Slim-Link® Web Server-Controller June 2001 Micro-Controller incorporates Web-Enabled, Real-time Operating System DESCRIPTION The Slim-Link family of Web Server-Controller products provides the ideal core technology for Internet enabled instruments and control systems. The Slim-Link Web Server Controllers are based on a 40 MHz AMD186ES microcontroller and feature MicroRTOS, a web enabled, real-time operating system developed spedifically for control system applications. MicroRTOS is embedded into each Slim-Link Web Server-Controller product with no additional cost or licensing fees. MicroRTOS MicroRTOS was created to simplify the process of designing a web enabled instrument or control system. This is accomplished by integrating a Preemptive Real-time Kernel, thin Web Server, and TCP/IP Stack into the fully-functioning operating system. The designer can then concentrate on the design of his application rather than integrating source codes from disparate applications. Three editions of MicroRTOS are available to support your application; the Basic edition, PPP Client Edition with Point-to-Point protocol for dial out applciations and the PPP Server Editon with Point-to-Point protocol for in bound dial-up applications. Models Six models of the Slim-Link® Web Server-Controller are currently offered. Each model is described below.

An AMD AM79C961A Ethernet Controller is linked to the AMD186 main controller to handle the local area network interface. The AM79C961 provides both the Ethernet Control functions and 10Base-T transceiver facilities. The integrated AM79C961A supports an IEEE 802.3 or ANSI 8802-3 compliant 10Base-T network connection. The ethernet controller handles all data framing, addressing and error detection tasks, and manages collision handling and avoidance. The AM79C961A operates in Bus Master mode permitting it to directly address all memory locations. The fixed Ethernet Physical address is stored in an on-board EEPROM with other configuration data. Slim-Link® Server Serial Ports The Slim-Link® Server includes a pair of serial ports for local communications. These ports come directly from the AM186 controller. Serial Port B supports hardware flow control lines as well as transmit and received data. Serial Port A supports only transmit and received data. Serial Port A Serial Port A corresponds to Serial Port 1 of the AM186 micro-controller. Serial Port A includes only the TXD (Transmit Data) and RXD (Received Data) signals. These signals are active low. Serial Port A does not support Hardware Flow Control. In-band flow control should be used instead. When using in-band flow control, predefined XON and XOFF characters serve as flow control signals from the controller and peripheral. The equipment places an XOFF character in the data stream when it can no longer accept data. An XON character is sent when data traffic can again be accepted. Serial Port A Signal TXDA RXDA AM186 Signal PIO27 PIO28 Serial Port B Serial Port B corresponds to Serial Port 0 of the AM186 micro-controller. Serial Port B includes hardware flow control lines RTS (Request to Send) and CTS (Clear to Send) as well as TXD (Transmit Data) and RXD (Received Data). All signals are active low. The hardware flow control lines regulate the flow of data between the Slim-Link® Server and its serial peripheral. When both devices can receive data the RTS and CTS lines remain active. The Slim-Link® Server should keep RTS active as long as it can accept data from the peripheral equipment. It should drop RTS to signal the peripheral equipment that it cannot accept data on RXD. The peripheral equipment will likewise manipulate CTS to indicate when it is unable to accept data on TXD. Serial Port B Signal TXDB RXDB RTSB CTSB AM186 Signal PIO22 PIO23 PIO20 PIO21 Advanced Web Communication (10) Slim-Link® Server AWC86A Analog Outputs The AWC86A includes two Analog Output pins. These outputs are supported by a 12-bit internal digital to analog convertor within the Slim-Link Server. Three of the AM186 Programmable Input/Output lines are used to support this function. Digital to Analog Convertor The Digital to Analog Convertor converts 24-bit serial data bytes into two analog output signals. The serial data is transmitted synchronously from the AM186 controller to the Digital to Analog Convertor. The first 12 bits define the level at DA0; the remaining 12 bits define the level at DA1. The maximum output voltage on either analog output is 4.095 volts, the Least Significant Bit equals 1 millivolt. The three signals which control the integral Digital to Analog Convertor are PIO3, PIO26 and PIO29. Serial data is presented to the digital to analog convertor on PIO26. The serial data clock is presented by PIO3. PIO3 controls the flow of data within the Digital to Analog Convertor. PIO3 low permits the serial data to be clocked into the input shift register. When PIO3 is high data is transferred from the shift register to the DAC Registers and updates the DA0 AND DA1 outputs. AWC86A Analog Input Lines The Slim-Link® Server is available with 8 Analog Input pins, AWC86A only. These inputs feed into a common 12-bit Analog to Digital Convertor, ADC. Three of the Programmable Input/Output lines from the AMD186 support these analog inputs. Analog to Digital Convertor, ADC An integral Analog to Digital Convertor converts the analog inputs to a serial digital data stream. The maximum sampling rate of the ADC is 16.8 KHz. The ADC provides 12-bit resolution; the least significant bit equals .00122 volts. The AWC86A multiplexes all eight analog inputs into a single ADC under the control of the AMD186 controller. With Programmable Input/Output 2 high the AMD186 controller sends the 4-bit multiplexor address on Programmable Input/Output 26. When Programmable Input/Output 2 is low, serial data flows from the ADC to the AMD186 controller on Programmable Input/Output 26. The synchronizing clock for the data is provided by the AMD186 on Programmable Input/Output 29. Analog Channel Selection As mentioned above, a 4-bit word is issued by the AMD186 controller to select the analog channel. The logic table below shows how each channel is addressed.

The Real-Time Clock tracks month, date, year, day, hours, minutes and seconds. Applying a battery voltage to Pin 24 permits the RealTime Clock to maintain the time when power is shut down to the AWC86A. The Real-Time Clock interfaces to the AM186 controller through Programmable Input/Output lines 15, 26, and 29. PIO15 controls the Real-Time Clock Reset. Reset must be high during serial communications and should be held low otherwise. PIO26 provides the serial data path to the Real-Time Clock. PIO29 provides the serial clock which synchronizes the data exchange with the AM186. Data sent to the Real-Time Clock is read on the Trailing edge of the serial clock; data is sent from the Real-Time Clock on the failing edge of the serial clock. Clock frequency should be no greater than 2 MHz. The Real-Time Clock stores Clock/Calendar data in seven registers. Other registers store control information and access a thirty byte RAM. Data can be read or written from the Real-Time Clock one register at a time or multiple registers may be addressed in a single burst. Command Byte: A command byte precedes each data transfer in the RealTime Clock. The bit mapping of the 8-bit command byte is shown below. Bit 7 - Most Significant Bit, Always 1 Bit 6 - 0 - Clock/Calendar Data 1 - RAM Data Bits 1-5 - Register Address Bit 0 - 0 - Write to Real-Time Clock 1 - Read from Real-Time Clock Clock/Calendar Registers: Seven registers store the clock and calendar information for the Real-Time Clock. Each of these registers is described below. Seconds: Register Address 00000 This register stores the second count in BCD form. The Clock Halt Flag is stored in bit seven. When this flag is set the clock’s oscillator is stopped. Minutes: Register Address 00001 This register stores the minute count in BCD form. Hours: Register Address 00010 This register stores the hour count in BCD form. Bit seven selects whether a 12-hour or 24-hour clock will be used. A 1 selects a 12-hour clock. When a 12-hour clock is used bit 5 stores AM/PM status. Date: Register Address 00011 This register stores the Date in BCD form. Month: Register Address 00100 This register stores the month in BCD form. Day: Register Address 00101 This register stores the day in BCD form. Year: Register Address 00110 This register stores the year in BCD form. Write Protect Register: Register address 00111 provides write protection for the Clock/Calendar Registers. New values cannot be written into these registers if bit seven of the Write Protect Register is set. Trickle Charge Register: The AWC86A can charge the battery used to backup the Real-Time Clock. The Trickle Charge Register, address 0100, controls the function. The bit-mapping of this register is shown below. The remaining bits set the maximum charging current as shown below.

Layer 7 4 3 2 1 Definition Application Transport Network Data Link Physical Embedded in Slim-Link® Server Web Server / Telnet Server / PPP / SMTP / SNMP TCP / UDP IP / ICMP ARP / Ethernet / PPP 10Base-T Protocol TCP UDP IP Definition Transport Control Protocol User Datagram Protocol Internet Protocol Description The Transport Control Protocol provides the means to insure that internet communications are reliable. The User Datagram Protocol facilitates the communication from one machine to another. The Internet Protocol performs three functions in internet communications: It defines the format of all data. It performs routing of the data through the network. I defines how hosts an routers should process the data packets. The Internet Control Message Protocol allows routers on the internet to report errors and unexpected occurrences. The Address Resolution Protocol increases internet efficiency by binding together machine IP addresses. Point ot Point Protocol permits the transport of datagrams over a point to point link such a analog modem connection. 10Base-T Ethernet provides a 10 Mbps communications bus over a twisted wire pair.
