RabbitCore RCM3305/RCM3315
1. INTRODUCTION
The RCM3305 and RCM3315 RabbitCore modules feature a
compact module that incorporates the latest revision of the powerful Rabbit® 3000 microprocessor, flash memory, mass storage
(serial flash), static RAM, and digital I/O ports. The RCM3305
and RCM3315 feature an integrated 10/100Base-T Ethernet port,
and provide for LAN and Internet-enabled systems to be built as
easily as serial-communication systems.
In addition to the features already mentioned above, the RCM3305 and RCM3315 have
two clocks (main oscillator and real-time clock), reset circuitry, and the circuitry necessary
for management of battery backup of the Rabbit 3000’s internal real-time clock and the
static RAM. Two 34-pin headers bring out the Rabbit 3000 I/O bus lines, parallel ports,
and serial ports.
The RCM3305’s and the RCM3315’s mass-storage capabilities make them suited to running
the optional Dynamic C FAT file system module and the featured remote application
update where data are stored and handled using the same directory file structure commonly used on PCs.
The RCM3305 or RCM3315 receives +3.3 V power from the customer-supplied motherboard on which it is mounted. The RCM3305 and RCM3315 can interface with all kinds
of CMOS-compatible digital devices through the motherboard.
The Development Kit has what you need to design your own microprocessor-based
system: a complete Dynamic C software development system and a Prototyping Board
that allows you to evaluate the RCM3305 or RCM3315, and to prototype circuits that
interface to the RCM3305 or RCM3315 module.

• Supports 1.15 Mbps IrDA transceiver
The RCM3900/RCM3910 and RCM3365/RCM3375 RabbitCore modules are similar to
the RCM3305/RCM3315 and RCM3309/RCM3319, but they use fixed NAND or removable media for their mass-storage memories instead of the fixed serial flash options of the
RCM3305/RCM3315 and the RCM3309/RCM3319.

a USB port with an RS-232/USB converter, or directly over an Ethernet link using the featured remote application update or the Dynamic C download manager with or without a
RabbitLink.
Appendix A provides detailed specifications for the RCM3305 and the RCM3315.

1.2 Comparing the RCM3309/RCM3319 and RCM3305/RCM3315
We can no longer obtain certain components for the RCM3305/RCM3315 RabbitCore
modules that support the originally specified -40°C to +70°C temperature range. Instead of
changing the design of the RCM3305/RCM3315 RabbitCore modules to handle available
components specified for the original temperature range, we decided to develop a new
product line — the RCM3309/RCM3319 — based on the RCM3900 RabbitCore modules
that were released for the same reason.
The RCM3309/RCM3319 modules are similar in form, dimensions, and function to the
RCM3305/RCM3315 modules. We strongly recommend that existing RCM3305/3315
customers and designers of new systems consider using the new RCM3309/RCM3319
RabbitCore modules.
This section compares the two lines of RabbitCore modules.
• Temperature Specifications — RCM3305/RCM3315 RabbitCore modules manufactured after May, 2008, are specified to operate at 0°C to +70°C. The RCM3309/
RCM3319, rated for -40°C to +85°C, are offered to customers requiring a larger
temperature range after May, 2008.
• Maximum Current — The RCM3305/RCM3315 draws 390 mA vs. the 325 mA
required by the RCM3309/RCM3319.
• LEDs — The SPEED and user (USR/BSY)LED locations have been swapped between
the RCM3305/RCM3315 and the RCM3309/RCM3319, the LNK/ACT LEDs have been
combined to one LED on the RCM3309/RCM3319, and the RCM3309/RCM3319 has
an FDX/COL LED instead of the SF LED on the RCM3305/RCM3315. The SF LED
on the RCM3305/RCM3315 blinks when data are being written to or read from the
serial flash. The FDX/COL LED on the RCM3309/RCM3319 indicates whether the
Ethernet connection is in full-duplex mode (steady on) or that a half-duplex connection
is experiencing collisions (blinks).
NOTE: The change in LED indicators means that there is no indication on the
RCM3309/RCM3319 when data are being written to or read from the serial flash.
• Ethernet chip. A different Ethernet controller chip is used on the RCM3309/RCM3319.
The Ethernet chip is able to detect automatically whether a crossover cable or a straightthrough cable is being used in a particular setup, and will configure the signals on the
Ethernet jack interface.
• Dynamic C — As long as no low-level FAT file system calls were used in your application developed for the RCM3305/RCM3315, you may run that application on the
RCM3309/RCM3319 after you recompile it using Dynamic C v. 9.60.

RabbitCore RCM3305/RCM3315
1.3 Advantages of the RCM3305 and RCM3315
• Fast time to market using a fully engineered, “ready-to-run/ready-to-program” microprocessor core.
• Competitive pricing when compared with the alternative of purchasing and assembling
individual components.
• Easy C-language program development and debugging
• Program download utility (Rabbit Field Utility) and cloning board options for rapid
production loading of programs.
• Generous memory size allows large programs with tens of thousands of lines of code,
and substantial data storage.
• Integrated Ethernet port for network connectivity, with royalty-free TCP/IP software.
• Ideal for network-enabling security and access systems, home automation, HVAC
systems, and industrial controls

RabbitCore RCM3305/RCM3315
1.4.2 Software
The RCM3305 and the RCM3315 are programmed using version 9.25 or later of Rabbit’s
Dynamic C. A compatible version is included on the Development Kit CD-ROM.
Dynamic C v. 9.60, which is required for the related RCM3309 and RCM3319 RabbitCore
modules, includes the popular µC/OS-II real-time operating system, point-to-point protocol (PPP), FAT file system, RabbitWeb, and other select libraries that were previously sold
as indidual Dynamic C modules.
Rabbit also offers for purchase the Rabbit Embedded Security Pack featuring the Secure
Sockets Layer (SSL) and a specific Advanced Encryption Standard (AES) library. In addition to the Web-based technical support included at no extra charge, a one-year telephonebased technical support subscription is also available for purchase. Visit our Web site at
www.rabbit.com for further information and complete documentation, or contact your
Rabbit sales representative or authorized distributor.
1.4.3 Connectivity Interface Kits
Rabbit has available a Connector Adapter Board.
• Connector Adapter Board (Part No. 151-0114)—allows you to plug the RCM3305/
RCM3315 whose headers have a 2 mm pitch into header sockets with a 0.1" pitch.
Visit our Web site at www.rabbit.com or contact your Rabbit sales representative or authorized distributor for further information.
1.4.4 Online Documentation
The online documentation is installed along with Dynamic C, and an icon for the documentation menu is placed on the workstation’s desktop. Double-click this icon to reach the
menu. If the icon is missing, use your browser to find and load default.htm in the docs
folder, found in the Dynamic C installation folder.
The latest versions of all documents are always available for free, unregistered download
from our Web sites as well.

2. GETTING STARTED
This chapter describes how to set up and use an RCM3305 series
module and the Prototyping Board included in the Development Kit.
NOTE: It is assumed that you have a Development Kit. If you purchased an RCM3305
series module by itself, you will have to adapt the information in this chapter and elsewhere to your test and development setup.
2.1 Install Dynamic C
To develop and debug programs for an RCM3305 series module (and for all other Rabbit
hardware), you must install and use Dynamic C.
If you have not yet installed Dynamic C version 9.25 (or a later version), do so now by
inserting the Dynamic C CD from the Development Kit in your PC’s CD-ROM drive. If
autorun is enabled, the CD installation will begin automatically.
If autorun is disabled or the installation otherwise does not start, use the Windows
Start | Run menu or Windows Disk Explorer to launch setup.exe from the root folder
of the CD-ROM.
The installation program will guide you through the installation process. Most steps of the
process are self-explanatory.
Dynamic C uses a COM (serial) port to communicate with the target development system.
The installation allows you to choose the COM port that will be used. The default selection is COM1. You may select any available port for Dynamic C’s use. If you are not certain which port is available, select COM1. This selection can be changed later within
Dynamic C.
NOTE: The installation utility does not check the selected COM port in any way. Specifying a port in use by another device (mouse, modem, etc.) may lead to a message such
as "could not open serial port" when Dynamic C is started.
Once your installation is complete, you will have up to three icons on your PC desktop.
One icon is for Dynamic C, one opens the documentation menu, and the third is for the
Rabbit Field Utility, a tool used to download precompiled software to a target system.
If you have purchased the optional Dynamic C Rabbit Embedded Security Pack, install it
after installing Dynamic C. You must install the Rabbit Embedded Security Pack in the
same directory where Dynamic C was installed.

2.2 Hardware Connections
There are three steps to connecting the Prototyping Board for use with Dynamic C and the
sample programs:
1. Attach the RCM3305 series RabbitCore module to the Prototyping Board.
2. Connect the programming cable between the RCM3305 series RabbitCore module and
the workstation PC.
3. Connect the power supply to the Prototyping Board.

Figure 2. Install the RCM3305/ Series Module on the Prototyping Board
NOTE: It is important that you line up the pins from the headers on the bottom side of the
RCM3305 series module exactly with the corresponding pins of header sockets JA and
JB on the Prototyping Board. The header pins may become bent or damaged if the pin
alignment is offset, and the module will not work. Permanent electrical damage to the
module may also result if a misaligned module is powered up.
Press the module’s pins firmly into the Prototyping Board header sockets—press down in
the area above the header pins using your thumbs or fingers over the connectors as shown
in Figure 2. Do not press down on the middle of the RCM3305 series module to avoid
flexing the module, which could damage the module or the components on the module.
Should you need to remove the RCM3305 series module, grasp it with your fingers along the
sides by the connectors and gently work the module up to pull the pins away from the sockets
where they are installed. Do not remove the module by grasping it at the top and bottom.

Programming Cable
Figure 3(b). Connect Programming Cable and Power Supply
NOTE: Be sure to use the serial programming cable (part number 101-0542)—the programming cable has blue shrink wrap around the RS-232 converter section located in the
middle of the cable. The USB programming cable and programming cables with clear or
red shrink wrap from other Rabbit kits are not designed to work with RCM3305/
RCM3315 modules.
Connect the other end of the programming cable to a COM port on your PC.
NOTE: It may be possible to use an RS-232/USB converter with the serial programming
described in this section. An RS-232/USB converter (part number 20-151-0178) is
available through the Web store. Note that not all RS-232/USB converters work with
Dynamic C.

RabbitCore RCM3305/RCM3315
2.2.3 Step 3 — Connect Power
When all other connections have been made, you can connect power to the Prototyping
Board.
If you have the universal power supply, prepare the AC adapter for the country where it
will be used by selecting the plug. The RCM3305 Series Development Kit presently
includes Canada/Japan/U.S., Australia/N.Z., U.K., and European style plugs. Snap in the
top of the plug assembly into the slot at the top of the AC adapter as shown in Figure 3(a),
then press down on the spring-loaded clip below the plug assembly to allow the plug
assembly to click into place.
Depending on the style of adapter, connect the AC adapter to 3-pin header J2 or jack J1 on
the Prototyping Board as shown in Figure 3(a) or Figure 3(b).
Plug in the AC adapter. The red CORE LED on the Prototyping Board should light up.
The RCM3305 series RabbitCore module and the Prototyping Board are now ready to be
used.
NOTE: A RESET button is provided on the Prototyping Board to allow a hardware reset
without disconnecting power.
2.2.3.1 Alternate Power-Supply Connections
All Development Kits sold up to May, 2008, included a header connector that may be used
to connect your power supply to 3-pin header J2 on the Prototyping Board. The connector
may be attached either way as long as it is not offset to one side—the center pin of J2 is
always connected to the positive terminal, and either edge pin is negative. The power
supply should deliver 8 V to 30 V DC at 8 W.
User’s Manual

2.3 Starting Dynamic C
NOTE: Dynamic C v. 9.60 or a later version is required if you are using an RCM3309 or
an RCM3319 RabbitCore module.
Once the RCM3305 series module is connected as described in the preceding pages, start
Dynamic C by double-clicking on the Dynamic C icon on your desktop or in your Start
menu. Select Code and BIOS in Flash, Run in RAM on the “Compiler” tab in the
Dynamic C Options > Project Options menu. Click OK.
If you are using a USB port to connect your computer to the RCM3305/RCM3315 module,
choose Options > Project Options and select “Use USB to Serial Converter” on the
Communications tab. Click OK.
2.4 Run a Sample Program
Use the File menu to open the sample program PONG.C, which is in the Dynamic C
SAMPLES folder. Press function key F9 to compile and run the program. The STDIO window will open on your PC and will display a small square bouncing around in a box.
This program shows that the CPU is working. The sample program described in
Section 6.5, “Run the PINGME.C Sample Program,” tests the TCP/IP portion of the board.
2.4.1 Troubleshooting
If Dynamic C cannot find the target system (error message "No Rabbit Processor
Detected."):
• Check that the RCM3305 series module is powered correctly — the red CORE LED on
the Prototyping Board should be lit when the module is mounted on the Prototyping Board and
the AC adapter is plugged in.
• Check both ends of the programming cable to ensure that they are firmly plugged into
the PC and the PROG connector, not the DIAG connector, is plugged in to the programming port on the RCM3305 series module with the marked (colored) edge of the programming cable towards pin 1 of the programming header.
• Ensure that the RCM3305 series module is firmly and correctly installed in its connectors on the Prototyping Board.
• Dynamic C uses the COM port or USB port specified during installation. Select a different COM port within Dynamic C. From the Options menu, select Project Options,
then select Communications. Select another COM port from the list, then click OK.
Press to force Dynamic C to recompile the BIOS. If Dynamic C still reports it
is unable to locate the target system, repeat the above steps until you locate the COM
port used by the programming cable.
• If you get an error message when you plugged the programming cable into a USB port,
you will have to install USB drivers. Drivers for Windows XP are available in the
Dynamic C Drivers\Rabbit USB Programming Cable\WinXP_2K folder —
double-click DPInst.exe to install the USB drivers. Drivers for other operating systems are available online at www.ftdichip.com/Drivers/VCP.htm.
14
RabbitCore RCM3305/RCM3315
If Dynamic C appears to compile the BIOS successfully, but you then receive a communication error message when you compile and load the sample program, it is possible that
your PC cannot handle the higher program-loading baud rate. Try changing the maximum
download rate to a slower baud rate as follows.
• Locate the Serial Options dialog in the Dynamic C Options > Project Options >
Communications menu. Select a slower Max download baud rate.
If a program compiles and loads, but then loses target communication before you can
begin debugging, it is possible that your PC cannot handle the default debugging baud
rate. Try lowering the debugging baud rate as follows.
• Locate the Serial Options dialog in the Dynamic C Options > Project Options >
Communications menu. Choose a lower debug baud rate.
2.5 Where Do I Go From Here?
If the sample program ran fine, you are now ready to go on to other sample programs and to
develop your own applications. The source code for the sample programs is provided to allow
you to modify them for your own use. The RCM3305/RCM3315 User’s Manual also
provides complete hardware reference information and describes the software function calls
for the RCM3305 and the RCM3315, the Prototyping Board, and the optional LCD/keypad
module. The RCM3309/RCM3319 User’s Manual also provides complete hardware reference information and describes the software function calls for the RCM3309 and the
RCM3319, the Prototyping Board, and the optional LCD/keypad module.
For advanced development topics, refer to the Dynamic C User’s Manual and the
Dynamic C TCP/IP User’s Manual, also in the online documentation set.

3. RUNNING SAMPLE PROGRAMS
To develop and debug programs for the RCM3305/RCM3315
(and for all other Rabbit hardware), you must install and use
Dynamic C.
3.1 Introduction
To help familiarize you with the RCM3305 and RCM3315 modules, Dynamic C includes
several sample programs. Loading, executing and studying these programs will give you a
solid hands-on overview of the RCM3305/RCM3315’s capabilities, as well as a quick
start using Dynamic C as an application development tool.
NOTE: The sample programs assume that you have at least an elementary grasp of the C
programming language. If you do not, see the introductory pages of the Dynamic C
User’s Manual for a suggested reading list.
More complete information on Dynamic C is provided in the Dynamic C User’s Manual.
In order to run the sample programs discussed in this chapter and elsewhere in this manual,
1. Your RCM3305/RCM3315 must be plugged in to the Prototyping Board as described
in Chapter 2, “Getting Started.”
2. Dynamic C must be installed and running on your PC.
3. The programming cable must connect the programming header on the RCM3305/
RCM3315 to your PC.
4. Power must be applied to the RCM3305/RCM3315 through the Prototyping Board.
Refer to Chapter 2, “Getting Started,” if you need further information on these steps.
To run a sample program, open it with the File menu, then press function key F9 to compile and run the program. The RCM3305/RCM3315 must be in Program Mode (see
Figure 8) and must be connected to a PC using the programming cable.
User’s Manual

3.2 Sample Programs
Of the many sample programs included with Dynamic C, several are specific to the
RCM3305 and the RCM3315. Sample programs illustrating the general operation of the
RCM3305/RCM3315, serial communication, and the serial flash are provided in the
SAMPLES\RCM3300 folder. Each sample program has comments that describe the purpose
and function of the program. Follow the instructions at the beginning of the sample program. Note that the RCM3305/RCM3315 must be installed on the Prototyping Board
when using the sample programs described in this chapter.
• CONTROLLED.c—Demonstrates use of the digital inputs by having you turn the LEDs
on the Prototyping Board on or off from the STDIO window on your PC.
Once you compile and run CONTROLLED.C, the following display will appear in the
Dynamic C STDIO window.
Press “2” or “3” or “4”or “5”on your keyboard to select LED DS3 or DS4 or DS5 or
DS6 on the Prototyping Board. Then follow the prompt in the Dynamic C STDIO window to turn the LED on or off.
• FLASHLED.c—Demonstrates assembly-language program by flashing the USR LED
on the RCM3305/RCM3315 and LEDs DS3, DS4, DS5, and DS6 on the Prototyping
Board.
• SWRELAY.c—Demonstrates the relay-switching function call using the relay installed
on the Prototyping Board through screw-terminal header J17.
• TOGGLESWITCH.c—Uses costatements to detect switches S2 and S3 using debouncing. The corresponding LEDs (DS3 and DS4) will turn on or off.
Once you have loaded and executed these five programs and have an understanding of
how Dynamic C and the RCM3305/RCM3315 modules interact, you can move on and try
the other sample programs, or begin building your own.

RabbitCore RCM3305/RCM3315
3.2.1 Use of Serial Flash
3.2.1.1 Onboard Serial Flash
The following sample programs can be found in the SAMPLES\RCM3300\SerialFlash
folder.
• SFLASH_INSPECT.c—This program is a handy utility for inspecting the contents of a
serial flash chip. When the sample program starts running, it attempts to initialize a
serial flash chip on Serial Port B. Once a serial flash chip is found, the user can perform
two different commands to either print out the contents of a specified page or clear (set
to zero) all the bytes in a specified page.
• SFLASH_LOG.c—This program runs a simple Web server and stores a log of hits in
the serial flash. This log can be viewed and cleared from a browser.
3.2.1.2 SF1000 Serial Flash Card
The following sample program can be found in the SAMPLES\RCM3300\SF1000 folder.
• SERFLASHTEST.c—An optional SF1000 Serial Flash card is required to run this demonstration. Install the Serial Flash card into socket J11 on the Prototyping Board. This
sample program demonstrates how to read and write from/to the Serial Flash card.
3.2.2 Serial Communication
The following sample programs can be found in the SAMPLES\RCM3300\SERIAL folder.
• FLOWCONTROL.C—This program demonstrates hardware flow control by configuring
Serial Port F for CTS/RTS with serial data coming from TxE (Serial Port E) at 115,200
bps. One character at a time is received and is displayed in the STDIO window.
To set up the Prototyping Board, you will need to tie
TxE and RxE together on the RS-232 header at J14,
and you will also tie TxF and RxF together as shown in
the diagram.
J14
TxE RxE GND TxF RxF 485+ GND 485
A repeating triangular pattern should print out in the
STDIO window. The program will periodically switch flow control on or off to demonstrate the effect of no flow control.
• PARITY.C—This program demonstrates the use of parity modes by repeatedly sending
byte values 0–127 from Serial Port E to Serial Port F. The program will switch between
generating parity or not on Serial Port E. Serial Port F will always be checking parity,
so parity errors should occur during every other sequence.
To set up the Prototyping Board, you will need to tie
TxE and RxF together on the RS-232 header at J14 as
shown in the diagram.
The Dynamic C STDIO window will display the error
sequence.
User’s Manual
J14
TxE RxE GND TxF RxF 485+ GND 485
19
• SIMPLE3WIRE.C—This program demonstrates basic RS-232 serial communication.
Lower case characters are sent by TxE, and are received by RxF. The characters are
converted to upper case and are sent out by TxF, are received by RxE, and are displayed
in the Dynamic C STDIO window.
To set up the Prototyping Board, you will need to tie
TxE and RxF together on the RS-232 header at J14, and
you will also tie RxE and TxF together as shown in the
diagram.
J14
TxE RxE GND TxF RxF 485+ GND 485
• SIMPLE5WIRE.C—This program demonstrates 5-wire RS-232 serial communication
with flow control on Serial Port F and data flow on Serial Port E.
To set up the Prototyping Board, you will need to tie
TxE and RxE together on the RS-232 header at J14,
and you will also tie TxF and RxF together as shown in
the diagram.
J14
TxE RxE GND TxF RxF 485+ GND 485
Once you have compiled and run this program, you can
test flow control by disconnecting TxF from RxF while the program is running. Characters will no longer appear in the STDIO window, and will display again once TxF is
connected back to RxF.
• SWITCHCHAR.C—This program transmits and then receives an ASCII string on Serial
Ports E and F. It also displays the serial data received from both ports in the STDIO
window.
To set up the Prototyping Board, you will need to tie
TxE and RxF together on the RS-232 header at J14, and
you will also tie RxE and TxF together as shown in the
diagram.
J14
TxE RxE GND TxF RxF 485+ GND 485
Once you have compiled and run this program, press
and release S2 and S3 on the Prototyping Board. The data sent between the serial ports
will be displayed in the STDIO window.
Two sample programs, SIMPLE485MASTER.C and SIMPLE485SLAVE.C, are available
to illustrate RS-485 master/slave communication. To run these sample programs, you will
need a second Rabbit-based system with RS-485—another Rabbit single-board computer
or RabbitCore module may be used as long as you use the master or slave sample program
associated with that board.
Before running either of these sample programs on the RCM3305/RCM3315 assembly,
make sure pins 1–2 and pins 5–6 are jumpered together on header JP5 to use the RS-485
bias and termination resistors. The sample programs use Serial Port C as the RS-485 serial
port, and they use PD7 to enable/disable the RS-485 transmitter.
20
RabbitCore RCM3305/RCM3315
The RS-485 connections between the slave and master devices are as follows.
•
RS485+ to RS485+
•
RS485– to RS485–
•
GND to GND
• SIMPLE485MASTER.C—This program demonstrates a simple RS-485 transmission of
lower case letters to a slave. The slave will send back converted upper case letters back
to the master and display them in the STDIO window. Use SIMPLE485SLAVE.C to
program the slave.
• SIMPLE485SLAVE.C—This program demonstrates a simple RS-485 transmission of
lower case letters to a master. The slave will send back converted upper case letters
back to the master and display them in the STDIO window. Use SIMPLE485MASTER.C
to program the master.
3.2.3 Real-Time Clock
If you plan to use the real-time clock functionality in your application, you will need to set
the real-time clock. Set the real-time clock using the SETRTCKB.C sample program from
the Dynamic C SAMPLES\RTCLOCK folder, using the onscreen prompts. The RTC_
TEST.C sample program in the Dynamic C SAMPLES\RTCLOCK folder provides additional examples of how to read and set the real-time clock.
3.2.4 RabbitNet
Sample programs are available for each RabbitNet peripheral card, and can be found in the
Dynamic C SAMPLES\RabbitNet folder. When you run any of these sample programs
in conjunction with the RCM3305/RCM3315 and the Prototyping Board, you need to add
the line
#use rcm33xx.lib
at the beginning of the sample program.
TIP: You need to add #use rcm33xx.lib at the beginning of any sample program
that is not in the Dynamic C SAMPLES\RCM3300 folder.
3.2.5 Other Sample Programs
Section 6.6 describes the TCP/IP sample programs, and Appendix C.7 provides sample
programs for the optional LCD/keypad module that can be installed on the Prototyping
Board.

RCM3315. Visit the Web site for further information.
Headers J3 and J4 are standard 2 × 34 headers with a nominal 2 mm pitch. An RJ-45 Ether-
net port is also included with the RCM3305/RCM3315.
Pins 29–32 on header J3 are configured using 0 Ω resistors at locations JP4, JP5, JP6, and
JP7 to be PD2, PD3, PD6, and PD7 respectively. They may also be reconfigured to carry
the Ethernet signals TPI+, TPI–, TPO+, and TPO–.
Pins 33 and 34 on header J3 are wired to carry the LINK and ACT signals that illuminated
the corresponding LEDs on the RCM3305/RCM3315 module. These signals may be “disconnected” by removing 0 Ω surface-mount resistors R41 and R42.
See Appendix A.5 for more information about the locations of these surface-mount
resistors.

Notes
1. When using pins 33–34 on header J3 to drive LEDs, these pins can handle a sinking
current of up to 8 mA.
2. The VRAM voltage is temperature-dependent. If the VRAM voltage drops below about
1.2 V to 1.5 V, the contents of the battery-backed SRAM may be lost. If VRAM drops
below 1.0 V, the 32 kHz oscillator could stop running. Pay careful attention to this voltage if you draw any current from this pin.

RabbitCore RCM3305/RCM3315
4.1.1 Memory I/O Interface
The Rabbit 3000 address lines (A0–A18) and all the data lines (D0–D7) are routed
internally to the onboard flash memory and SRAM chips. I/0 write (/IOWR) and I/0 read
(/IORD) are available for interfacing to external devices.
Parallel Port A can also be used as an external I/O data bus to isolate external I/O from the
main data bus. Parallel Port B pins PB2–PB5 and PB7 can also be used as an external
address bus.
When using the external I/O bus for a digital output or the LCD/keypad module on the
Prototyping Board, or for any other reason, you must add the following line at the beginning of your program.
#define PORTA_AUX_IO
// required to enable external I/O bus
4.1.2 Other Inputs and Outputs
The status, /RESET_IN, SMODE0, and SMODE1 I/O are normally associated with the
programming port. Since the status pin is not used by the system once a program has been
downloaded and is running, the status pin can then be used as a general-purpose CMOS
output. The programming port is described in more detail in Section 4.2.3.
/RES is an output from the reset circuitry that can be used to reset external peripheral
devices.
4.1.3 LEDs
The RCM3305/RCM3315 has three Ethernet status LEDs located beside the RJ-45 Ethernet jack—these are discussed in Section 4.2.
Addiitionally, there are two other LEDs. The SF LED at DS3 blinks when data are being
written to or read from the flash mass-storage device. The red USR LED at DS3 is a userprogrammable LED, which is controlled by PD0 on the Rabbit 3000’s Parallel Port D. The
sample program FLASHLED.C provided in the Dynamic C SAMPLES\RCM3300 folder
shows how to set up and use this user-programmable LED.
User’s Manual

4.2 Serial Communication
The RCM3305/RCM3315 does not have any serial transceivers directly on the board.
However, a serial interface may be incorporated into the board the RCM3305/RCM3315
is mounted on. For example, the Prototyping Board has RS-232 and RS-485 transceiver
chips.
4.2.1 Serial Ports
There are six serial ports designated as Serial Ports A, B, C, D, E, and F. All six serial
ports can operate in an asynchronous mode up to the baud rate of the system clock divided
by 8. An asynchronous port can handle 7 or 8 data bits. A 9th bit address scheme, where
an additional bit is sent to mark the first byte of a message, is also supported.
Serial Port A is normally used as a programming port, but may be used either as an asynchronous or as a clocked serial port once the RCM3305/RCM3315 has been programmed
and is operating in the Run Mode.
Serial Port B is used to communicate with the serial flash on the RCM3305/RCM3315 and
is not available for other use.
Serial Ports C and D can also be operated in the clocked serial mode. In this mode, a clock
line synchronously clocks the data in or out. Either of the two communicating devices can
supply the clock.
Serial Ports E and F can also be configured as HDLC serial ports. The IrDA protocol is
also supported in SDLC format by these two ports.

4.2.3 Programming Port
The RCM3305/RCM3315 is programmed either through the serial programming port,
which is accessed using header J1, or through the Ethernet jack. The RabbitLink may be
used to provide a serial connection via the RabbitLink’s Ethernet jack. The programming
port uses the Rabbit 3000’s Serial Port A for communication; Serial Port A is not used
when programming is done over an Ethernet connection via the Dynamic C download
manager or the remote application update. Dynamic C uses the programming port to
download and debug programs.
The programming port is also used for the following operations.
• Cold-boot the Rabbit 3000 on the RCM3305/RCM3315 after a reset.
• Remotely download and debug a program over an Ethernet connection using the
RabbitLink EG2110.
• Fast copy designated portions of flash memory from one Rabbit-based board (the
master) to another (the slave) using the Rabbit Cloning Board.
In addition to Serial Port A, the Rabbit 3000 startup-mode (SMODE0, SMODE1), status,
and reset pins are available on the programming port.
The two startup mode pins determine what happens after a reset—the Rabbit 3000 is
either cold-booted or the program begins executing at address 0x0000.
The status pin is used by Dynamic C to determine whether a Rabbit microprocessor is
present. The status output has three different programmable functions:
1. It can be driven low on the first op code fetch cycle.
2. It can be driven low during an interrupt acknowledge cycle.
3. It can also serve as a general-purpose CMOS output.
The /RESET_IN pin is an external input that is used to reset the Rabbit 3000 and the
RCM3305/RCM3315 onboard peripheral circuits. The serial programming port can be
used to force a hard reset on the RCM3305/RCM3315 by asserting the /RESET_IN signal.
Alternate Uses of the Programming Port
All three clocked Serial Port A signals are available as
• a synchronous serial port
• an asynchronous serial port, with the clock line usable as a general CMOS I/O pin
The programming port may also be used as a serial port once the application is running.
The SMODE pins may then be used as inputs and the status pin may be used as an output.
Refer to the Rabbit 3000 Microprocessor User’s Manual for more information.

RabbitCore RCM3305/RCM3315
4.3 Programming Cable
The programming cable is used to connect the programming port of the RCM3305/
RCM3315 to a PC serial COM port. The programming cable converts the RS-232 voltage
levels used by the PC serail port to the CMOS voltage levels used by the Rabbit 3000.
When the PROG connector on the programming cable is connected to the RCM3305/
RCM3315 programming port, programs can be downloaded and debugged over the serial
interface.
The DIAG connector of the programming cable may be used on header J1 of the RCM3305/
RCM3315 with the RCM3305/RCM3315 operating in the Run Mode. This allows the
programming port to be used as a regular serial port.
4.3.1 Changing Between Program Mode and Run Mode
The RCM3305/RCM3315 is automatically in Program Mode when the PROG connector
on the programming cable is attached, and is automatically in Run Mode when no programming cable is attached. When the Rabbit 3000 is reset, the operating mode is determined by the state of the SMODE pins. When the programming cable’s PROG connector
is attached, the SMODE pins are pulled high, placing the Rabbit 3000 in the Program
Mode. When the programming cable’s PROG connector is not attached, the SMODE pins
are pulled low, causing the Rabbit 3000 to operate in the Run Mode.

A program “runs” in either mode, but can only be downloaded and debugged when the
RCM3305/RCM3315 is in the Program Mode.
Refer to the Rabbit 3000 Microprocessor User’s Manual for more information on the programming port.
4.3.2 Standalone Operation of the RCM3305/RCM3315
The RCM3305/RCM3315 must be programmed via the Prototyping Board or via a similar
arrangement on a customer-supplied board. Once the RCM3305/RCM3315 has been programmed successfully, remove the programming cable from the programming connector
and reset the RCM3305/RCM3315. The RCM3305/RCM3315 may be reset by cycling the
power off/on or by pressing the RESET button on the Prototyping Board. The RCM3305/
RCM3315 module may now be removed from the Prototyping Board for end-use
installation.
CAUTION: Disconnect power to the Prototyping Board or other boards when removing
or installing your RCM3305/RCM3315 module to protect against inadvertent shorts
across the pins or damage to the RCM3305/RCM3315 if the pins are not plugged in
correctly. Do not reapply power until you have verified that the RCM3305/RCM3315
module is plugged in correctly.

RabbitCore RCM3305/RCM3315
4.4 Other Hardware
4.4.1 Clock Doubler
The RCM3305/RCM3315 takes advantage of the Rabbit 3000 microprocessor’s internal
clock doubler. A built-in clock doubler allows half-frequency crystals to be used to reduce
radiated emissions. The 44.2 MHz frequency specified for the RCM3305/RCM3315 is
generated using a 22.12 MHz resonator.
The clock doubler may be disabled if 44.2 MHz clock speeds are not required. This will
reduce power consumption and further reduce radiated emissions. The clock doubler is
disabled with a simple configuration macro as shown below.
1. Select the “Defines” tab from the Dynamic C Options > Project Options menu.
2. Add the line CLOCK_DOUBLED=0 to always disable the clock doubler.
The clock doubler is enabled by default, and usually no entry is needed. If you need to
specify that the clock doubler is always enabled, add the line CLOCK_DOUBLED=1 to
always enable the clock doubler.
3. Click OK to save the macro. The clock doubler will now remain off whenever you are
in the project file where you defined the macro.
4.4.2 Spectrum Spreader
The Rabbit 3000 features a spectrum spreader, which helps to mitigate EMI problems. The
spectrum spreader is on by default, but it may also be turned off or set to a stronger setting.
The means for doing so is through a simple configuration macro as shown below.
1. Select the “Defines” tab from the Dynamic C Options > Project Options menu.
2. Normal spreading is the default, and usually no entry is needed. If you need to specify
normal spreading, add the line
ENABLE_SPREADER=1
For strong spreading, add the line
ENABLE_SPREADER=2
To disable the spectrum spreader, add the line
ENABLE_SPREADER=0
NOTE: The strong spectrum-spreading setting is unnecessary for the RCM3305/RCM3315.
3. Click OK to save the macro. The spectrum spreader will now be set to the state specified
by the macro value whenever you are in the project file where you defined the macro.
NOTE: Refer to the Rabbit 3000 Microprocessor User’s Manual for more information
on the spectrum-spreading setting and the maximum clock speed.
User’s Manual

4.5 Memory
4.5.1 SRAM
RCM3305/RCM3315 boards have 512K of program-execution fast SRAM at U11. The
program-execution SRAM is not battery-backed. There are 512K of battery-backed data
SRAM installed at U10.
4.5.2 Flash EPROM
RCM3305/RCM3315 boards also have 512K of flash EPROM at U9.
NOTE: Rabbit recommends that any customer applications should not be constrained by
the sector size of the flash EPROM since it may be necessary to change the sector size
in the future.
Writing to arbitrary flash memory addresses at run time is also discouraged. Instead, use a
portion of the “user block” area to store persistent data. The functions writeUserBlock() and readUserBlock() are provided for this. Refer to the Rabbit 3000
Microprocessor Designer’s Handbook and the Dynamic C Function Reference Manual for
additional information.
4.5.3 Serial Flash
A serial flash is supplied on the RCM3305 and the RCM3315 to store data and Web pages.
Sample programs in the SAMPLES\RCM3300 folder illustrate the use of the serial flash.
These sample programs are described in Section 3.2.1, “Use of Serial Flash.”
4.5.4 Dynamic C BIOS Source Files
The Dynamic C BIOS source files handle different standard RAM and flash EPROM sizes
automatically.

RabbitCore RCM3305/RCM3315
5. SOFTWARE REFERENCE
Dynamic C is an integrated development system for writing
embedded software. It runs on an IBM-compatible PC and is
designed for use with controllers based on the Rabbit microprocessor. Chapter 5 describes the libraries and function calls
related to the RCM3305/RCM3315.
5.1 More About Dynamic C
Dynamic C has been in use worldwide since 1989. It is specially designed for programming embedded systems, and features quick compile and interactive debugging. A complete reference guide to Dynamic C is contained in the Dynamic C User’s Manual.
You have a choice of doing your software development in the flash memory or in the static
SRAM included on the RCM3305/RCM3315. The flash memory and SRAM options are
selected with the Options > Program Options > Compiler menu.
The advantage of working in RAM is to save wear on the flash memory, which is limited
to about 100,000 write cycles. The disadvantage is that the code and data might not both
fit in RAM.
NOTE: An application should be run from the program execution SRAM after the programming cable is disconnected. Your final code must always be stored in flash memory
for reliable operation. RCM3305/RCM3315 modules running at 44.2 MHz have a fast
program execution SRAM that is not battery-backed. Select Code and BIOS in Flash,
Run in RAM from the Dynamic C Options > Project Options > Compiler menu to
store the code in flash and copy it to the fast program execution SRAM at run-time to
take advantage of the faster clock speed. This option optimizes the performance of
RCM3305/RCM3315 modules running at 44.2 MHz.
NOTE: Do not depend on the flash memory sector size or type in your program logic.
The RCM3305/RCM3315 and Dynamic C were designed to accommodate flash
devices with various sector sizes in response to the volatility of the flash-memory
market.
Developing software with Dynamic C is simple. Users can write, compile, and test C and
assembly code without leaving the Dynamic C development environment. Debugging
occurs while the application runs on the target. Alternatively, users can compile a program
to an image file for later loading. Dynamic C runs on PCs under Windows 2000 and
later—see Rabbit’s Technical Note TN257, Running Dynamic C® With Windows Vista®,
User’s Manual
37
for additional information if you are using a Dynamic C release prior to v. 9.60 under Windows Vista. Programs can be downloaded at baud rates of up to 460,800 bps after the program compiles.
Dynamic C has a number of standard features.
• Full-feature source and/or assembly-level debugger, no in-circuit emulator required.
• Royalty-free TCP/IP stack with source code and most common protocols.
• Hundreds of functions in source-code libraries and sample programs:
X Exceptionally fast support for floating-point arithmetic and transcendental functions.
X RS-232 and RS-485 serial communication.
X Analog and digital I/O drivers.
X I2C, SPI, GPS, file system.
X LCD display and keypad drivers.
• Powerful language extensions for cooperative or preemptive multitasking
• Loader utility program to load binary images into Rabbit targets in the absence of
Dynamic C.
• Provision for customers to create their own source code libraries and augment on-line
help by creating “function description” block comments using a special format for
library functions.
• Standard debugging features:
X Breakpoints—Set breakpoints that can disable interrupts.
X Single-stepping—Step into or over functions at a source or machine code level, µC/OS-II aware.
X Code disassembly—The disassembly window displays addresses, opcodes, mnemonics, and
machine cycle times. Switch between debugging at machine-code level and source-code level by
simply opening or closing the disassembly window.
X Watch expressions—Watch expressions are compiled when defined, so complex expressions
including function calls may be placed into watch expressions. Watch expressions can be updated
with or without stopping program execution.
X Register window—All processor registers and flags are displayed. The contents of general registers
may be modified in the window by the user.
X Stack window—shows the contents of the top of the stack.
X Hex memory dump—displays the contents of memory at any address.
X STDIO window—printf outputs to this window and keyboard input on the host PC can be
detected for debugging purposes. printf output may also be sent to a serial port or file.

5.1.1 Developing Programs Remotely with Dynamic C
Dynamic C is an integrated development environment that allows you to edit, compile,
and debug your programs. Dynamic C has the ability to allow programming over the
Internet or local Ethernet. This is accomplished in one of two ways.
1. Via the Rabbit RabbitLink, which allows a Rabbit-based target to have programs downloaded to it and debugged with the same ease as exists when the target is connected
directly to a PC.
2. The RCM3305/RCM3315 has a featured remote application update written specifically
to allow the RCM3305/RCM3315 to be programmed over the Internet or local Ethernet. These programs, DLP_STATIC.C and DLP_WEB.C, are available in the Dynamic C
SAMPLES\RCM3300\RemoteApplicationUpdate folder. Complete information on
the use of these programs is provided in the Remote Application Update instructions,
which are available with the online documentation.
Dynamic C provides sample programs to illustrate the use of a download manager.
User’s Manual
39
5.2 Dynamic C Functions
5.2.1 Digital I/O
The RCM3305/RCM3315 was designed to interface with other systems, and so there are
no drivers written specifically for the I/O. The general Dynamic C read and write functions allow you to customize the parallel I/O to meet your specific needs. For example, use
WrPortI(PEDDR, &PEDDRShadow, 0x00);
to set all the Port E bits as inputs, or use
WrPortI(PEDDR, &PEDDRShadow, 0xFF);
to set all the Port E bits as outputs.
When using the external I/O bus on the Rabbit 3000 chip, add the line
#define PORTA_AUX_IO
// required to enable external I/O bus
to the beginning of any programs using the external I/O bus.
The sample programs in the Dynamic C SAMPLES/RCM3300 folder provide further
examples.
5.2.2 SRAM Use
The RCM3305/RCM3315 have a battery-backed data SRAM and a program-execution
SRAM. Dynamic C provides the protected keyword to identify variables that are to be
placed into the battery-backed SRAM. The compiler generates code that creates a backup
copy of a protected variable before the variable is modified. If the system resets while the
protected variable is being modified, the variable's value can be restored when the system
restarts.
The sample code below shows how a protected variable is defined and how its value can
be restored.
protected nf_device nandFlash;
int main() {
...
_sysIsSoftReset();
// restore any protected variables
The bbram keyword may also be used instead if there is a need to store a variable in battery-backed SRAM without affecting the performance of the application program. Data
integrity is not assured when a reset or power failure occurs during the update process.
Additional information on bbram and protected variables is available in the Dynamic C
User’s Manual.
40
RabbitCore RCM3305/RCM3315
5.2.3 Serial Communication Drivers
Library files included with Dynamic C provide a full range of serial communications support. The RS232.LIB library provides a set of circular-buffer-based serial functions. The
PACKET.LIB library provides packet-based serial functions where packets can be delimited
by the 9th bit, by transmission gaps, or with user-defined special characters. Both libraries
provide blocking functions, which do not return until they are finished transmitting or
receiving, and nonblocking functions, which must be called repeatedly until they are finished, allowing other functions to be performed between calls. For more information, see
the Dynamic C Function Reference Manual and Technical Note TN213, Rabbit Serial
Port Software.
5.2.4 TCP/IP Drivers
The TCP/IP drivers are located in the LIB\TCPIP folder. Complete information on these
libraries and the TCP/IP functions is provided in the Dynamic C TCP/IP User’s Manual.
5.2.5 Serial Flash Drivers
The Dynamic C SerialFlash\SFLASH.LIB library is used to interface to serial flash
memory devices on an SPI bus such as the serial flash on board the RCM3305 and the
RCM3315, which use Serial Port B as an SPI port. The library has two sets of function
calls—the first is maintained for compatibility with previous versions of the SFLASH.LIB
library. The functions are all blocking and only work for single flash devices. The new
functions, which should be used for the RCM3305/RCM3315, make use of an
sf_device structure as a handle for a specific serial flash device. This allows multiple
devices to be used by an application.
More information on these function calls is available in the Dynamic C Function Reference Manual.

6. USING THE TCP/IP FEATURES
6.1 TCP/IP Connections
Programming and development can be done with the RCM3305/RCM3315 modules without connecting the Ethernet port to a network. However, if you will be running the sample
programs that use the Ethernet capability or will be doing Ethernet-enabled development,
you should connect the RCM3305/RCM3315 module’s Ethernet port at this time.
Before proceeding you will need to have the following items.
• If you don’t have Ethernet access, you will need at least a 10Base-T Ethernet card
(available from your favorite computer supplier) installed in a PC.
• Two RJ-45 straight-through Ethernet cables and a hub, or an RJ-45 crossover Ethernet
cable.
A straight-through and a crossover Ethernet cable are included in both the RCM3305/
RCM3315 Development Kit. Figure 9 shows how to identify the two cables based on the
wires in the transparent RJ-45 connectors.

Now you should be able to make your connections.
1. Connect the AC adapter and the programming cable as shown in Chapter 2, “Getting
Started.”
2. Ethernet Connections
There are four options for connecting the RCM3305/RCM3315 module to a network
for development and runtime purposes. The first two options permit total freedom of
action in selecting network addresses and use of the “network,” as no action can interfere with other users. We recommend one of these options for initial development.
• No LAN — The simplest alternative for desktop development. Connect the
RCM3305/RCM3315 module’s Ethernet port directly to the PC’s network interface
card using an RJ-45 crossover cable. A crossover cable is a special cable that flips
some connections between the two connectors and permits direct connection of two client systems. A standard RJ-45 network cable will not work for this purpose.
• Micro-LAN — Another simple alternative for desktop development. Use a small Ethernet 10Base-T hub and connect both the PC’s network interface card and the
RCM3305/RCM3315 module’s Ethernet port to it using standard network cables.
The following options require more care in address selection and testing actions, as
conflicts with other users, servers and systems can occur:
• LAN — Connect the RCM3305/RCM3315 module’s Ethernet port to an existing
LAN, preferably one to which the development PC is already connected. You will need
to obtain IP addressing information from your network administrator.
• WAN — The RCM3305/RCM3315 is capable of direct connection to the Internet and
other Wide Area Networks, but exceptional care should be used with IP address
settings and all network-related programming and development. We recommend that
development and debugging be done on a local network before connecting a RabbitCore system to the Internet.
TIP: Checking and debugging the initial setup on a micro-LAN is recommended before
connecting the system to a LAN or WAN.
The PC running Dynamic C does not need to be the PC with the Ethernet card.
3. Apply Power
Plug in the AC adapter. The RCM3305/RCM3315 module and Prototyping Board are
now ready to be used.

RabbitCore RCM3305/RCM3315
6.2 TCP/IP Primer on IP Addresses
Obtaining IP addresses to interact over an existing, operating, network can involve a number of complications, and must usually be done with cooperation from your ISP and/or
network systems administrator. For this reason, it is suggested that the user begin instead
by using a direct connection between a PC and the RCM3305/RCM3315 using an Ethernet crossover cable or a simple arrangement with a hub. (A crossover cable should not be
confused with regular straight through cables.)
In order to set up this direct connection, the user will have to use a PC without networking,
or disconnect a PC from the corporate network, or install a second Ethernet adapter and set
up a separate private network attached to the second Ethernet adapter. Disconnecting your
PC from the corporate network may be easy or nearly impossible, depending on how it is
set up. If your PC boots from the network or is dependent on the network for some or all
of its disks, then it probably should not be disconnected. If a second Ethernet adapter is
used, be aware that Windows TCP/IP will send messages to one adapter or the other,
depending on the IP address and the binding order in Microsoft products. Thus you should
have different ranges of IP addresses on your private network from those used on the corporate network. If both networks service the same IP address, then Windows may send a
packet intended for your private network to the corporate network. A similar situation will
take place if you use a dial-up line to send a packet to the Internet. Windows may try to
send it via the local Ethernet network if it is also valid for that network.
The following IP addresses are set aside for local networks and are not allowed on the
Internet: 10.0.0.0 to 10.255.255.255, 172.16.0.0 to 172.31.255.255, and 192.168.0.0 to
192.168.255.255.
The RCM3305/RCM3315 uses a 10/100Base-T type of Ethernet connection, which is the
most common scheme. The RJ-45 connectors are similar to U.S. style telephone connectors, except they are larger and have 8 contacts.
An alternative to the direct connection using a crossover cable is a direct connection using
a hub. The hub relays packets received on any port to all of the ports on the hub. Hubs are
low in cost and are readily available. The RCM3305/RCM3315 uses 10/100 Mbps Ethernet, so the hub or Ethernet adapter can be a 10 Mbps unit, a 100 Mbps unit, or a 10/100
Mbps unit.
In a corporate setting where the Internet is brought in via a high-speed line, there are typically machines between the outside Internet and the internal network. These machines
include a combination of proxy servers and firewalls that filter and multiplex Internet traffic. In the configuration below, the RCM3305/RCM3315 could be given a fixed address
so any of the computers on the local network would be able to contact it. It may be possible to configure the firewall or proxy server to allow hosts on the Internet to directly contact the controller, but it would probably be easier to place the controller directly on the
external network outside of the firewall. This avoids some of the configuration complications by sacrificing some security.

your mail server, and your domain name for some of the sample programs.

RabbitCore RCM3305/RCM3315
6.2.1 IP Addresses Explained
IP (Internet Protocol) addresses are expressed as 4 decimal numbers separated by periods,
for example:
216.103.126.155
10.1.1.6
Each decimal number must be between 0 and 255. The total IP address is a 32-bit number
consisting of the 4 bytes expressed as shown above. A local network uses a group of adjacent IP addresses. There are always 2N IP addresses in a local network. The netmask (also
called subnet mask) determines how many IP addresses belong to the local network. The
netmask is also a 32-bit address expressed in the same form as the IP address. An example
netmask is:
255.255.255.0
This netmask has 8 zero bits in the least significant portion, and this means that 28
addresses are a part of the local network. Applied to the IP address above
(216.103.126.155), this netmask would indicate that the following IP addresses belong to
the local network:
216.103.126.0
216.103.126.1
216.103.126.2
etc.
216.103.126.254
216.103.126.255
The lowest and highest address are reserved for special purposes. The lowest address
(216.102.126.0) is used to identify the local network. The highest address
(216.102.126.255) is used as a broadcast address. Usually one other address is used for the
address of the gateway out of the network. This leaves 256 - 3 = 253 available IP
addresses for the example given.
User’s Manual
53
6.2.2 How IP Addresses are Used
The actual hardware connection via an Ethernet uses Ethernet adapter addresses (also
called MAC addresses). These are 48-bit addresses and are unique for every Ethernet
adapter manufactured. In order to send a packet to another computer, given the IP address
of the other computer, it is first determined if the packet needs to be sent directly to the
other computer or to the gateway. In either case, there is an Ethernet address on the local
network to which the packet must be sent. A table is maintained to allow the protocol
driver to determine the MAC address corresponding to a particular IP address. If the table
is empty, the MAC address is determined by sending an Ethernet broadcast packet to all
devices on the local network asking the device with the desired IP address to answer with
its MAC address. In this way, the table entry can be filled in. If no device answers, then
the device is nonexistent or inoperative, and the packet cannot be sent.
Some IP address ranges are reserved for use on internal networks, and can be allocated
freely as long as no two internal hosts have the same IP address. These internal IP
addresses are not routed to the Internet, and any internal hosts using one of these reserved
IP addresses cannot communicate on the external Internet without being connected to a
host that has a valid Internet IP address. The host would either translate the data, or it
would act as a proxy.
Each RCM3305/RCM3315 RabbitCore module has its own unique MAC address, which
consists of the prefix 0090C2 followed by a code that is unique to each RCM3305/
RCM3315 module. For example, a MAC address might be 0090C2C002C0.
TIP: You can always obtain the MAC address on your board by running the sample program DISPLAY_MAC.C from the SAMPLES\TCPIP folder.
54
RabbitCore RCM3305/RCM3315
6.2.3 Dynamically Assigned Internet Addresses
In many instances, devices on a network do not have fixed IP addresses. This is the case
when, for example, you are assigned an IP address dynamically by your dial-up Internet
service provider (ISP) or when you have a device that provides your IP addresses using
the Dynamic Host Configuration Protocol (DHCP). The RCM3305/RCM3315 modules
can use such IP addresses to send and receive packets on the Internet, but you must take
into account that this IP address may only be valid for the duration of the call or for a
period of time, and could be a private IP address that is not directly accessible to others on
the Internet. These addresses can be used to perform some Internet tasks such as sending
e-mail or browsing the Web, but it is more difficult to participate in conversations that
originate elsewhere on the Internet. If you want to find out this dynamically assigned IP
address, under Windows 98 you can run the winipcfg program while you are connected
and look at the interface used to connect to the Internet.
Many networks use IP addresses that are assigned using DHCP. When your computer
comes up, and periodically after that, it requests its networking information from a DHCP
server. The DHCP server may try to give you the same address each time, but a fixed IP
address is usually not guaranteed.
If you are not concerned about accessing the RCM3305/RCM3315 from the Internet, you
can place the RCM3305/RCM3315 on the internal network using an IP address assigned
either statically or through DHCP.
User’s Manual
55
6.3 Placing Your Device on the Network
In many corporate settings, users are isolated from the Internet by a firewall and/or a
proxy server. These devices attempt to secure the company from unauthorized network
traffic, and usually work by disallowing traffic that did not originate from inside the network. If you want users on the Internet to communicate with your RCM3305/RCM3315,
you have several options. You can either place the RCM3305/RCM3315 directly on the
Internet with a real Internet address or place it behind the firewall. If you place the
RCM3305/RCM3315 behind the firewall, you need to configure the firewall to translate
and forward packets from the Internet to the RCM3305/RCM3315.

6.4 Running TCP/IP Sample Programs
We have provided a number of sample programs demonstrating various uses of TCP/IP for
networking embedded systems. These programs require you to connect your PC and the
RCM3305/RCM3315 board together on the same network. This network can be a local private network (preferred for initial experimentation and debugging), or a connection via the
Internet.

6.4.1 How to Set IP Addresses in the Sample Programs
With the introduction of Dynamic C 7.30 we have taken steps to make it easier to run
many of our sample programs. You will see a TCPCONFIG macro. This macro tells
Dynamic C to select your configuration from a list of default configurations. You will
have three choices when you encounter a sample program with the TCPCONFIG macro.
1. You can replace the TCPCONFIG macro with individual MY_IP_ADDRESS, MY_NETMASK, MY_GATEWAY, and MY_NAMESERVER macros in each program.
2. You can leave TCPCONFIG at the usual default of 1, which will set the IP configurations
to 10.10.6.100, the netmask to 255.255.255.0, and the nameserver and gateway
to 10.10.6.1. If you would like to change the default values, for example, to use an IP
address of 10.1.1.2 for the RCM3305/RCM3315 board, and 10.1.1.1 for your PC,
you can edit the values in the section that directly follows the “General Configuration”
comment in the TCP_CONFIG.LIB library. You will find this library in the LIB\TCPIP
directory.
3. You can create a CUSTOM_CONFIG.LIB library and use a TCPCONFIG value greater
than 100. Instructions for doing this are at the beginning of the TCP_CONFIG.LIB
library in the LIB\TCPIP directory.
There are some other “standard” configurations for TCPCONFIG that let you select different features such as DHCP. Their values are documented at the top of the TCP_CONFIG.LIB library in the LIB\TCPIP directory. More information is available in the
Dynamic C TCP/IP User’s Manual.

6.4.2 How to Set Up your Computer for Direct Connect
Follow these instructions to set up your PC or notebook. Check with your administrator if
you are unable to change the settings as described here since you may need administrator
privileges. The instructions are specifically for Windows 2000, but the interface is similar
for other versions of Windows.
TIP: If you are using a PC that is already on a network, you will disconnect the PC from
that network to run these sample programs. Write down the existing settings before
changing them to facilitate restoring them when you are finished with the sample programs and reconnect your PC to the network.
1. Go to the control panel (Start > Settings > Control Panel), and then double-click the
Network icon.
2. Select the network interface card used for the Ethernet interface you intend to use (e.g.,
TCP/IP Xircom Credit Card Network Adapter) and click on the “Properties” button.
Depending on which version of Windows your PC is running, you may have to select
the “Local Area Connection” first, and then click on the “Properties” button to bring up
the Ethernet interface dialog. Then “Configure” your interface card for a “10Base-T
Half-Duplex” or an “Auto-Negotiation” connection on the “Advanced” tab.
NOTE: Your network interface card will likely have a different name.
3. Now select the IP Address tab, and check Specify an IP Address, or select TCP/IP and
click on “Properties” to assign an IP address to your computer (this will disable “obtain
an IP address automatically”):
IP Address : 10.10.6.101
Netmask : 255.255.255.0
Default gateway : 10.10.6.1
4. Click or to exit the various dialog boxes.

6.5 Run the PINGME.C Sample Program
Connect the crossover cable from your computer’s Ethernet port to the RCM3305/
RCM3315 board’s RJ-45 Ethernet connector. Open this sample program from the SAMPLES\TCPIP\ICMP folder, compile the program, and start it running under Dynamic C.
The crossover cable is connected from your computer’s Ethernet adapter to the RCM3305/
RCM3315 board’s RJ-45 Ethernet connector. When the program starts running, the green
LINK light on the RCM3305/RCM3315 module should be on to indicate an Ethernet connection is made. (Note: If the LNK light does not light, you may not be using a crossover
cable, or if you are using a hub perhaps the power is off on the hub.)
The next step is to ping the board from your PC. This can be done by bringing up the MSDOS window and running the pingme program:
ping 10.10.6.101
or by Start > Run
and typing the entry
ping 10.10.6.101
Notice that the yellow ACT light flashes on the RCM3305/RCM3315 module while the
ping is taking place, and indicates the transfer of data. The ping routine will ping the board
four times and write a summary message on the screen describing the operation.
6.6 Running Additional Sample Programs With Direct Connect
The following sample programs are in the Dynamic C SAMPLES\RCM3300\TCPIP\
folder.
• BROWSELED.C—This program demonstrates a basic controller running a Web page.
Two “device LEDs” are created along with two buttons to toggle them. Users can use
their Web browser to change the status of the lights. The DS3 and DS4 LEDs on the
Prototyping Board will match those on the Web page. As long as you have not modified
the TCPCONFIG 1 macro in the sample program, enter the following server address in
your Web browser to bring up the Web page served by the sample program.
http://10.10.6.100
Otherwise use the TCP/IP settings you entered in the TCP_CONFIG.LIB library.
• MBOXDEMO.C—The optional LCD/keypad module (see Appendix C) must be plugged
in to the Prototyping Board when using this sample program. This program demonstrates sending e-mail messages that are then shown on the LCD/keypad module display. The keypad is used to scroll through a menu to view the messages, flip to other
messages, mark messages as read, and delete messages. When a new e-mail arrives, an
LED on the LCD/keypad module turns on, and then turns off once the message has
been marked as read. A log of all e-mail actions is kept, and can be displayed in the
Web browser. All current e-mails can also be read with the Web browser.
• PINGLED.C—This program demonstrates ICMP by pinging a remote host. It will flash
LEDs DS3 and DS4 on the Prototyping Board when a ping is sent and received.
60
RabbitCore RCM3305/RCM3315
• SMTP.C—This program demonstrates using the SMTP library to send an e-mail when
the S2 and S3 switches on the Prototyping Board are pressed. LEDs DS3 and DS4 on
the Prototyping Board will light up when e-mail is being sent.
6.6.1 RabbitWeb Sample Programs
You will need to have the Dynamic C RabbitWeb module installed before you run the
sample programs described in this section. The following sample programs are in the
Dynamic C SAMPLES\RCM3300\TCPIP\RABBITWEB folder.
• BLINKLEDS.C—This program demonstrates a basic example to change the rate at
which the DS3 and DS4 LEDs on the Prototyping Board blink.
• DOORMONITOR.C—The optional LCD/keypad module (see Appendix C) must be plugged
in to the Prototyping Board when using this sample program. This program demonstrates adding and monitoring passwords entered via the LCD/keypad module.
• SPRINKLER.C—This program demonstrates how to schedule times for the relay and
digital outputs in a 24-hour period.
6.6.2 Remote Application Update
The following programs that make up the featured application for the RCM3305/
RCM3315 can be found in the SAMPLES\RCM3300\RemoteApplicationUpdate folder.
• DLP_STATIC.C—This program uses the TCP/IP HTTP.LIB library, and outputs a
basic static Web page.
• DLP_WEB.C—This program outlines a basic download program with a Web interface.
Complete information on the use of these programs is provided in the Remote Application
Update instructions, which are available with the online documentation.
6.6.3 Dynamic C FAT File System, RabbitWeb, and SSL Modules
The Dynamic C FAT File System, RabbitWeb, and Secure Sockets Layer (SSL) modules
have been integrated into a sample program for the RCM3305 and the RCM3315. The
sample program requires that you have installed the Dynamic C FAT File System, RabbitWeb, and SSL modules.
TIP: Before running any of the sample programs described in this section, you should
look at and run sample programs for the TCP/IP ZSERVER.LIB library, the FAT file
system, RabbitWeb, SSL, the download manager, and HTTP upload to become more
familiar with their operation.
The INTEGRATION.C sample program in the SAMPLES\RCM3300\Module_Integration folder demonstrates the use of the TCP/IP ZSERVER.LIB library and FAT file system functionality with RabbitWeb dynamic HTML content, all secured using SSL. The
sample program also supports dynamic updates of both the application and its resources
using the Rabbit Download Manager (DLM) and HTTP upload capability, respectively—
note that neither of these currently supports SSL security.

First, you need to format and partition the serial flash. Find the FMT_DEVICE.C sample
program in the Dynamic C SAMPLES\FileSystem folder. Open this sample program
with the File > Open menu, then compile and run it by pressing F9. FMT_DEVICE.C
formats the mass storage device for use with the FAT file system. If the serial flash or
NAND flash is already formatted, FMT_DEVICE.C gives you the option of erasing the
mass storage flash and reformatting it with a single large partition. This erasure does not
check for non-FAT partitions and will destroy all existing partitions.
Next, run the INTEGRATION_FAT_SETUP.C sample program in the Dynamic C
SAMPLES\RCM3300\Module_Integration folder. Open this sample program with the
File > Open menu, then compile and run it by pressing F9. INTEGRATION_FAT_
SETUP.C will copy some #ximported files into the FAT file system.
The last step to complete before you can run the INTEGRATION.C sample program is to
create an SSL certificate. The SSL walkthrough in the online documentation for the
Dynamic C SSL module explains how to do this.
Now you are ready to run the INTEGRATION.C sample program in the Dynamic C
SAMPLES\RCM3300\Module_Integration folder. Open this sample program with the
File > Open menu, then compile and run it by pressing F9.
NOTE: Since HTTP upload and the Dynamic C SSL module currently do not work
together, compiling the INTEGRATION.C sample program will generate a serious
warning. Ignore the warning because we are not using HTTP upload over SSL. A
macro (HTTP_UPLOAD_SSL_SUPRESS_WARNING) is available to suppress the
warning message.
Open a Web browser, and browse to the device using the IP address from the TCP_
CONFIG.LIB library or the URL you assigned to the device. The humidity monitor will
be displayed in your Web browser. This page is accessible via plain HTTP or over SSLsecured HTTPS. Click on the administrator link to bring up the admin page, which is
secured automatically using SSL with a user name and a password. Use myadmin for user
name and use myadmin for the password.
The admin page demonstrates some RabbitWeb capabilities and provides access to the
HTTP upload page. Click the upload link to bring up the HTTP upload page, which allows
you to choose new files for both the humidity monitor and the admin page. If your browser
prompts you again for your user name and password, they are the same as above.
Note that the upload page is a static page included in the program flash, and can only be
updated by recompiling and downloading the application. This page is protected so that
you cannot accidentally change the upload page, possibly restricting yourself from performing future updates.
To try out the update capability, click the upload link on the admin page and choose a simple text file to replace monitor.ztm. Open another browser window and load the main
page. You will see that your text file has replaced the humidity monitor. To restore the
monitor, go back to the other window, click back to go to the upload page again, and
choose HUMIDITY_MONITOR.ZHTML to replace monitor.ztm and click Upload.

RabbitCore RCM3305/RCM3315
When you refresh the page in your browser, you will see that the page has been restored.
You have successfully updated and restored your application's files remotely!
When you are finished with the INTEGRATION.C sample program, you need to follow a
special shutdown procedure before powering off to prevent any possible corruption of the
FAT file system. Press and hold switch S2 on the Prototyping Board until LED DS3 blinks
rapidly to indicate that it is now safe to turn the RCM3305/RCM3315 off. This procedure
can be modified by the user to provide other application-specific shutdown tasks.
6.7 Where Do I Go From Here?
NOTE: If you purchased your RCM3305/RCM3315 through a distributor or through a
Rabbit partner, contact the distributor or partner first for technical support.
If there are any problems at this point:
• Use the Dynamic C Help menu to get further assistance with Dynamic C.
• Check the Rabbit Technical Bulletin Board and forums at www.rabbit.com/support/bb/
and at www.rabbit.com/forums/.
• Use the Technical Support e-mail form at www.rabbit.com/support/questionSubmit.shtml.

The measurements are taken at the 50% points under the following conditions.
• T = -40°C to 85°C, V = VDD ±10%
• Internal clock to nonloaded CLK pin delay ≤ 1 ns @ 85°C/3.0 V
The clock to address output delays are similar, and apply to the following delays.
• Tadr, the clock to address delay
• TCSx, the clock to memory chip select delay
• TIOCSx, the clock to I/O chip select delay
• TIORD, the clock to I/O read strobe delay
• TIOWR, the clock to I/O write strobe delay
• TBUFEN, the clock to I/O buffer enable delay
The data setup time delays are similar for both Tsetup and Thold.
When the spectrum spreader is enabled with the clock doubler, every other clock cycle is
shortened (sometimes lengthened) by a maximum amount given in the table above. The
shortening takes place by shortening the high part of the clock. If the doubler is not
enabled, then every clock is shortened during the low part of the clock period. The maximum shortening for a pair of clocks combined is shown in the table.

A.4 I/O Buffer Sourcing and Sinking Limit
Unless otherwise specified, the Rabbit I/O buffers are capable of sourcing and sinking
6.8 mA of current per pin at full AC switching speed. Full AC switching assumes a
22.1 MHz CPU clock and capacitive loading on address and data lines of less than 100 pF
per pin. The absolute maximum operating voltage on all I/O is 5.5 V.

APPENDIX B. PROTOTYPING BOARD
Appendix B describes the features and accessories of the Prototyping Board.
User’s Manual
79
B.1 Introduction
The Prototyping Board included in the Development Kit makes it easy to connect an
RCM3305/RCM3315 module to a power supply and a PC workstation for development. It
also provides some basic I/O peripherals (RS-232, RS-485, a relay, LEDs, and switches),
as well as a prototyping area for more advanced hardware development.
For the most basic level of evaluation and development, the Prototyping Board can be
used without modification.
As you progress to more sophisticated experimentation and hardware development, modifications and additions can be made to the board without modifying or damaging the
RCM3305/RCM3315 module itself.
The Prototyping Board is shown below in Figure B-1, with its main features identified.

RabbitCore RCM3305/RCM3315
B.1.1 Prototyping Board Features
• Power Connection—A power-supply jack and a 3-pin header are provided for connection to the power supply. Note that the 3-pin header is symmetrical, with both outer
pins connected to ground and the center pin connected to the raw V+ input. The cable
of the AC adapter provided with the North American version of the Development Kit
ends in a plug that connects to the power-supply jack (J1). A header plug leading to
bare leads is provided for overseas customers to connect their power supply to the 3-pin
header (J2)—the center pin of J2 is always connected to the positive terminal, and
either edge pin is negative.
Users providing their own power supply should ensure that it delivers 8–30 V DC at 1 A.
• Regulated Power Supply—The raw DC voltage provided at the POWER IN jack is
routed to a 5 V switching voltage regulator, then to a separate 3.3 V linear regulator.
The regulators provide stable power to the RCM3305/RCM3315 module and the Prototyping Board. The voltage regulators will get warm while in use.
• Power LED—The power LED lights whenever power is connected to the Prototyping
Board.
• Core LED—The core LED lights whenever an RCM3305/RCM3315 module is
plugged in correctly on the Prototyping Board and the RCM3305/RCM3315 module is
not being reset.
• Relay LED—The relay LED lights whenever the Prototyping Board relay is energized.
• Reset Switch—A momentary-contact, normally open switch is connected directly to the
RCM3305/RCM3315’s /RESET_IN pin. Pressing the switch forces a hardware reset of
the system.
• I/O Switches and LEDs—Two momentary-contact, normally open switches are connected to the PG0 and PG1 pins of the RCM3305/RCM3315 module and may be read
as inputs by sample applications.
Four user LEDs (DS3–DS6) are connected to alternate I/O bus pins PA0–PA3 pins of
the RCM3305/RCM3315 module via U8, and may be driven as output indicators. PE7
and PG5 control the registers in U8 as shown in the sample applications.
• Prototyping Area—A generous prototyping area has been provided for the installation
of through-hole components. +3.3 V, +5 V, and Ground buses run along one edge of
this area. Several areas for surface-mount devices are also available. Each SMT pad is
connected to a hole designed to accept a 30 AWG solid wire.
• LCD/Keypad Module—Rabbit’s LCD/keypad module may be plugged in directly to
headers LCD1JA, LCD1JB, and LCD1JC. The signals on headers LCD1JB and
LCD1JC will be available only if the LCD/keypad module is plugged in to header
LCD1JA. Appendix C provides complete information for mounting and using the
LCD/keypad module.
User’s Manual
81
• Module Extension Headers—The complete pin set of the RCM3305/RCM3315
module is duplicated at headers J8 and J9. Developers can solder wires directly into the
appropriate holes, or, for more flexible development, 2 × 17 header strips with a 0.1"
pitch can be soldered into place. See Figure B-4 for the header pinouts.
• Digital I/O—Four digital inputs are available on screw-terminal header J6. See
Figure B-4 for the header pinouts.
• RS-232—Two 3-wire serial ports or one 5-wire RS-232 serial port are available on the
Prototyping Board at screw-terminal header J14.
• RS-485—One RS-485 serial port is available on the Prototyping Board at screw-terminal header J14.
• Quadrature Decoder—Four quadrature decoder inputs (PF0–PF3) from the Rabbit
3000 chip are available on screw-terminal header J5. See Figure B-4 for the header
pinouts.
• H-Bridge Motor Driver—Two pairs of H-bridge motor drivers are supported using
screw-terminal headers J3 and J4 on the Prototyping Board for stepper-motor control.
See Figure B-4 for the header pinouts.
• RabbitNet Port—One RS-422 RabbitNet port (shared with the serial flash interface) is
available to allow RabbitNet peripheral cards to be used with the Prototyping Board.
• Serial Flash Interface—One serial flash interface (shared with the RabbitNet port) is
available to allow Rabbit’s SF1000 series serial flash to be used on the Prototyping
Board.

B.3 Power Supply
The RCM3305/RCM3315 requires a regulated 3.15 V to 3.45 V DC power source to operate. Depending on the amount of current required by the application, different regulators
can be used to supply this voltage.
The Prototyping Board has an onboard +5 V switching power regulator from which a
+3.3 V linear regulator draws its supply. Thus both +5 V and +3.3 V are available on the
Prototyping Board.
The Prototyping Board itself is protected against reverse polarity by a diode at D1 as
shown in Figure B-3.

RabbitCore RCM3305/RCM3315
The Prototyping Board comes with the basic components necessary to demonstrate the
operation of the RCM3305/RCM3315. Four user LEDs (DS3–DS6) are connected to
alternate I/O bus pins PA0–PA3 pins of the RCM3305/RCM3315 module via U8, and may
be driven as output indicators when controlled by PE7 and PG5 as shown in the sample
applications. Two switches (S2 and S3) are connected to PG0 and PG1 to demonstrate the
interface to the Rabbit 3000 microprocessor. Reset switch S1 is the hardware reset for the
RCM3305/RCM3315.
The Prototyping Board provides the user with RCM3305/RCM3315 connection points
brought out conveniently to labeled points at J8 and J9 on the Prototyping Board. Although
locations J8 and J9 are unstuffed, 2 × 17 headers are included in the bag of parts.
RS-232 and RS-485 signals are available on screw-terminal header J14, quadrature decoder
inputs are available on screw-terminal header J5, and digital inputs are available on screwterminal header J6. A 1 × 5 header strip from the bag of parts may be installed at J12 for four
sinking digital outputs. The clocked Serial Port B signals from the RCM3305/RCM3315
are used for the serial flash, and cannot be accessed via header J13 on the Prototyping
Board.
If you don’t plan to use the LCD/keypad module, additional signals may be brought out on 1 × 5
and 1 × 8 headers from the bag of parts that you install at J15 and J16. If you don’t plan to use
the stepper-motor control option, additional CMOS outputs are available via a 1 × 8 header
that you install at J10.
There is a through-hole prototyping space available on the Prototyping Board. The holes in
the prototyping area are spaced at 0.1" (2.5 mm). +3.3 V, +5 V, and GND traces run along
one edges of the prototyping area. Small to medium circuits can be prototyped using pointto-point wiring with 20 to 30 AWG wire between the prototyping area, the +3.3 V, +5 V, and
GND traces, and the surrounding area where surface-mount components may be installed.
Small holes are provided around the surface-mounted components that may be installed
around the prototyping area.
B.4.1 Adding Other Components
There are two sets of pads for 6-pin, 16-pin, and 28-pin devices that can be used for surface-mount prototyping devices. There are also pads that can be used for SMT resistors
and capacitors in an 0805 SMT package. Each component has every one of its pin pads
connected to a hole in which a 30 AWG wire can be soldered (standard wire wrap wire can
be soldered in for point-to-point wiring on the Prototyping Board). Because the traces are
very thin, carefully determine which set of holes is connected to which surface-mount pad.

B.4.2 Digital I/O
B.4.2.1 Digital Inputs
The Prototyping Board has four digital inputs, IN0–IN3, each of which is protected over a
range of –36 V to +36 V. The inputs are pulled up to +3.3 V as shown in Figure B-5.

Figure B-5. Prototyping Board Digital Inputs
The four quadrature decoder inputs on screw-terminal header J5 may be used as inputs
IN4–IN7. To use the PF0 signal from the Rabbit microprocessor, which goes to QD1B,
remember to reconfigure the jumper on header JP3 to jumper pins 1–2.
The actual switching threshold is between 0.9 V and 2.3 V. Anything below this value is a
logic 0, and anything above is a logic 1.
The digital inputs are each fully protected over a range of -36 V to +36 V, and can handle
short spikes of ±40 V.

B.4.4 Sinking Digital Outputs
Four sinking digital outputs shared with LEDs DS3–DS6 are available at J12, and can each
handle up to 500 mA. Figure B-6 shows a wiring diagram for a typical sinking output.

B.4.6.1 RS-232
RS-232 serial communication on the Prototyping Board is supported by an RS-232 transceiver installed at U9. This transceiver provides the voltage output, slew rate, and input
voltage immunity required to meet the RS-232 serial communication protocol. Basically,
the chip translates the Rabbit 3000’s signals to RS-232 signal levels. Note that the polarity
is reversed in an RS-232 circuit so that a +5 V output becomes approximately -10 V and 0
V is output as +10 V. The RS-232 transceiver also provides the proper line loading for
reliable communication.
RS-232 can be used effectively at the RCM3305/RCM3315 module’s maximum baud rate
for distances of up to 15 m.
RS-232 flow control on an RS-232 port is initiated in software using the
serXflowcontrolOn() function call from LIB\RS232.LIB, where X is the serial port
(E or F). The locations of the flow control lines are specified using a set of five macros.
SERX_RTS_PORT—Data register for the parallel port that the RTS line is on (e.g., PGDR).
SERX_RTS_SHADOW—Shadow register for the RTS line's parallel port (e.g., PGDRShadow).
SERX_RTS_BIT—The bit number for the RTS line.
SERX_CTS_PORT—Data register for the parallel port that the CTS line is on (e.g., PCDRShadow).
SERX_CTS_BIT—The bit number for the CTS line.
Standard 3-wire RS-232 communication using Serial Ports E and F is illustrated in the following sample code.
#define EINBUFSIZE 15
#define EOUTBUFSIZE 15
// set size of circular buffers in bytes
#define FINBUFSIZE 15
#define FOUTBUFSIZE 15

B.4.6.2 RS-485
The Prototyping Board has one RS-485 serial channel, which is connected to the Rabbit
3000 Serial Port C through an RS-485 transceiver. The half-duplex communication uses
an output from PD7 on the Rabbit 3000 to control the transmit enable on the communication line. Using this scheme a strict master/slave relationship must exist between devices
to insure that no two devices attempt to drive the bus simultaneously.
Serial Port C is configured in software for RS-485 as follows.
#define
#define
#define
#define
#define
#define

ser485getc serCgetc
#define CINBUFSIZE 15
#define COUTBUFSIZE 15
#ifndef _485BAUD
#define _485BAUD 115200
#endif
The configuration shown above is based on circular buffers. RS-485 configuration may
also be done using functions from the PACKET.LIB library.

The Prototyping Boards with RCM3305/RCM3315 modules installed can be used in an
RS-485 multidrop network spanning up to 1200 m (4000 ft), and there can be as many as
32 attached devices. Connect the 485+ to 485+ and 485– to 485– using single twisted-pair
wires as shown in Figure B-8. Note that a common ground is recommended.

The Prototyping Board comes with a 220 Ω termination resistor and two 681 Ω bias resistors installed and enabled with jumpers across pins 1–2 and 5–6 on header JP5, as shown
in Figure B-9.

Figure B-9. RS-485 Termination and Bias Resistors
For best performance, the termination resistors in a multidrop network should be enabled
only on the end nodes of the network, but not on the intervening nodes. Jumpers on boards
whose termination resistors are not enabled may be stored across pins 1–3 and 4–6 of
header JP5.
B.4.7 RabbitNet Ports
The RJ-45 jack labeled RabbitNet is a clocked SPI RS-422 serial I/O expansion port for
use with RabbitNet peripheral boards. The RabbitNet jack does not support Ethernet connections. Header JP3 must have pins 2–3 jumpered when using the RabbitNet port.
The RabbitNet port is enabled in software by setting PD2 = 1. Note that the RabbitNet
port and the J11 interface cannot be used simultaneously.
User’s Manual
93
B.4.8 Other Prototyping Board Modules
An optional LCD/keypad module is available that can be mounted on the Prototyping
Board. The signals on headers LCD1JB and LCD1JC will be available only if the LCD/
keypad module is installed. Refer to Appendix C, “LCD/Keypad Module,” for complete
information.
Rabbit’s SF1000 series serial flash may be installed in the socket labeled J11. The J11
interface is enabled in software by setting PD2 = 0. Header JP3 must have pins 2–3 jumpered when using the J11 interface. Note that the RabbitNet port and the J11 interface
cannot be used simultaneously.
B.4.9 Quadrature Decoder
Four quadrature decoder inputs are available on screw-terminal header J5. To use the PF0
input from the Rabbit microprocessor, which goes to the QD1B input, remember to reconfigure the jumper on header JP3 to jumper pins 1–2.
Additional information on the use of the quadrature decoders on Parallel Port F is provided in the Rabbit 3000 Microprocessor User’s Manual.
B.4.10 Stepper-Motor Control
The Prototyping Board can be used to demonstrate the use of the RCM3305/RCM3315 to
control a stepper motor. Stepper motor control typically directs moves in two orthogonal
directions, and so two sets of stepper-motor control circuits are provided for via screwterminal headers J3 and J4.

Figure C-1.
LCD/Keypad Modules
Figure C-1. LCD/Keypad Module Versions
Only the version without the bezel can mount directly on the Prototyping Board; if you
have the version with a bezel, you will have to remove the bezel to be able to mount the
LCD/keypad module on the Prototyping Board. Either version of the LCD/keypad module
can be installed at a remote location up to 60 cm (24") away. Contact your Rabbit sales
representative or your authorized for further assistance in purchasing an LCD/keypad
module.

C.2 Contrast Adjustments for All LCD/Keypad Modules
Starting in 2005, LCD/keypad modules were factory-configured to optimize their contrast
based on the voltage of the system they would be used in. Be sure to select a KDU3V
LCD/keypad module for use with the Prototyping Board for the RCM3305/RCM3315 —
these modules operate at 3.3 V. You may adjust the contrast using the potentiometer at R2
as shown in Figure C-3. LCD/keypad modules configured for 5 V may be used with the
3.3 V RCM3300 Prototyping Board, but the backlight will be dim.

Figure C-3. LCD/Keypad Module Contrast Adjustments
You can set the contrast on the LCD display of pre-2005 LCD/keypad modules by adjusting the potentiometer at R2 or by setting the voltage for 3.3 V by connecting the jumper
across pins 3–4 on header J5 as shown in Figure C-3. Only one of these two options is
available on these LCD/keypad modules.
NOTE: Older LCD/keypad modules that do not have a header at J5 or a contrast adjustment potentiometer at R2 are limited to operate only at 5 V, and will not work with the
Prototyping Board for the RCM3305/RCM3315. The older LCD/keypad modules are
no longer being sold.

C.7 Sample Programs
Sample programs illustrating the use of the LCD/keypad module with the Prototyping
Board are provided in the SAMPLES\RCM3300\LCD_KEYPAD folder.
These sample programs use the external I/O bus on the Rabbit 3000 chip, and so the
#define PORTA_AUX_IO line is already included in the sample programs.
Each sample program has comments that describe the purpose and function of the program. Follow the instructions at the beginning of the sample program. To run a sample
program, open it with the File menu (if it is not still open), then compile and run it by

APPENDIX D. POWER SUPPLY
Appendix D provides information on the current requirements
of the RCM3305/RCM3315, and includes some background on
the reset generator.
D.1 Power Supplies
Power is supplied from the motherboard to which the RCM3305/RCM3315 is connected
via header J4. The RCM3305/RCM3315 requires a regulated 3.15 V to 3.45 V DC power
source. An RCM3305/RCM3315 with no loading at the outputs operating at 44.2 MHz
typically draws 350 mA.
D.1.1 Battery Backup
The RCM3305/RCM3315 does not have a battery, but there is provision for a customersupplied battery to back up the data SRAM and keep the internal Rabbit 3000 real-time
clock running.
Header J4, shown in Figure D-1, allows access to the external battery. This header makes
it possible to connect an external 3 V power supply. This allows the SRAM and the internal Rabbit 3000 real-time clock to retain data with the RCM3305/RCM3315 powered
down.

A lithium battery with a nominal voltage of 3 V and a minimum capacity of 165 mA·h is
recommended. A lithium battery is strongly recommended because of its nearly constant
nominal voltage over most of its life.
The drain on the battery by the RCM3305/RCM3315 is typically 6 µA when no other power
is supplied. If a 165 mA·h battery is used, the battery can last about 3 years:
165 mA·h
------------------------ = 3.1 years.
6 µA
The RCM3305/RCM3315 does not drain the battery while it is powered up normally.
Cycle the main power off/on on the RCM3305/RCM3315 after you install a backup battery
for the first time, and whenever you replace the battery. This step will minimize the current
drawn by the real-time clock oscillator circuit from the backup battery should the
RCM3305/RCM3315 experience a loss of main power.
NOTE: Remember to cycle the main power off/on any time the RCM3305/RCM3315 is
removed from the Protoyping Board or motherboard since that is where the backup
battery would be located.
Rabbit’s Technical Note TN235, External 32.768 kHz Oscillator Circuits, provides additional information about the current draw by the the real-time clock oscillator circuit.

Figure D-2. RCM33305/RCM3315 Backup Battery Circuit
The battery-backup circuit serves three purposes:
• It reduces the battery voltage to the SRAM and to the real-time clock, thereby limiting
the current consumed by the real-time clock and lengthening the battery life.
• It ensures that current can flow only out of the battery to prevent charging the battery.
• A voltage, VOSC, is supplied to U1, which keeps the 32.768 kHz oscillator working
when the voltage begins to drop.

RabbitCore RCM3305/RCM3315
D.1.3 Reset Generator
The RCM3305/RCM3315 uses a reset generator to reset the Rabbit 3000 microprocessor
when the voltage drops below the voltage necessary for reliable operation. The reset occurs
between 2.85 V and 3.00 V, typically 2.93 V.
The RCM3305/RCM3315 has a reset pin, pin 28 on header J4. This pin provides access to
the reset input of the reset generator, whose output drives the reset input of the Rabbit
3000 and peripheral circuits. The /RESET output from the reset generator is available on
pin 1 of header J4 on the RCM3305/RCM3315, and can be used to reset user-defined circuits on the motherboard on which the RCM3305/RCM3315 module is mounted.

APPENDIX E. RABBITNET
E.1 General RabbitNet Description
RabbitNet is a high-speed synchronous protocol developed by Rabbit to connect peripheral cards to a master and to allow them to communicate with each other.
E.1.1 RabbitNet Connections
All RabbitNet connections are made point to point. A RabbitNet master port can only be
connected directly to a peripheral card, and the number of peripheral cards is limited by
the number of available RabbitNet ports on the master.

Use a straight-through Ethernet cable to connect the master to slave peripheral cards, unless
you are using a device such as the OP7200 that could be used either as a master or a slave. In
this case you would use a crossover cable to connect an OP7200 that is being used as a slave.
Distances between a master unit and peripheral cards can be up to 10 m or 33 ft.

RabbitCore RCM3305/RCM3315
E.2 Physical Implementation
There are four signaling functions associated with a RabbitNet connection. From the master’s point of view, the transmit function carries information and commands to the peripheral card. The receive function is used to read back information sent to the master by the
peripheral card. A clock is used to synchronize data going between the two devices at high
speed. The master is the source of this clock. A slave select (SS) function originates at the
master, and when detected by a peripheral card causes it to become selected and respond
to commands received from the master.
The signals themselves are differential RS-422, which are series-terminated at the source.
With this type of termination, the maximum frequency is limited by the round-trip delay
time of the cable. Although a peripheral card could theoretically be up to 45 m (150 ft)
from the master for a data rate of 1 MHz, Rabbit recommends a practical limit of 10 m (33
ft).
Connections between peripheral cards and masters are done using standard 8-conductor
Ethernet cables. Masters and peripheral cards are equipped with RJ-45 8-pin female connectors. The cables may be swapped end for end without affecting functionality.
E.2.1 Control and Routing
Control starts at the master when the master asserts the slave select signal (SS). Then it
simultaneously sends a serial command and clock. The first byte of a command contains
the address of the peripheral card if more than one peripheral card is connected.
A peripheral card assumes it is selected as soon as it receives the select signal. For direct
master-to-peripheral-card connections, this is as soon as the master asserts the select signal. The connection is established once the select signal reaches the addressed slave. At
this point communication between the master and the selected peripheral card is established, and data can flow in both directions simultaneously. The connection is maintained
so long as the master asserts the select signal.

E.3 Function Calls
The function calls described in this section are used with all RabbitNet peripheral cards,
and are available in the RNET.LIB library in the Dynamic C RABBITNET folder.
int rn_init(char portflag, char servicetype);
Resets, initializes, or disables a specified RabbitNet port on the master single-board computer. During
