A P T E R 1 Hardware Overview The following figure identifies various Digi Connect SP and Digi Connect Wi-SP connectors, LEDs and switches. Digi Connect SP Hardware Overview DB-9 Ethernet connector Power LEDs MEI switch Reset button Note: MEI switches and the Reset button are in the same location for both the Digi Connect SP and Digi Connect Wi-SP. 6 Digi Connect Wi-SP Overview LEDs Digi Connect SP and Digi Connect Wi-SP have three LEDs. Two LEDs are connected directly to the hardware; the other is software programmable. See the following table for more information. LED Descriptions LED Power Color Red (labeled PWR) Purpose This LED is software programmable. The default is that this LED indicates power (and is therefore always on). See “LEDs” on page 15 for more information Network link status: – On - unit is associated with an access point Link ACT 7 Green Yellow Digi Connect SP Hardware Reference – Blinking slowly - unit is in ad hoc mode – Blinking quickly - unit is scanning for a network This LED is wired to the Ethernet hardware. – On indicates bad initialization – Off indicates ready – Blinking indicates network activity Reset Button The behavior of the reset button is user-defined. See “Reset Button” on page 16 and the NS520 BSP Porting Guide for LED programming information. Antenna The Digi Connect Wi-SP is available with 1 RP-SMA connector. The antenna is connected to the product with a reverse polarity SMA connector (sub-miniature size A). The antenna only fits on the product one way to ensure a proper connection. Another option for both signal reception and design flexibility is to use a 30cm antenna extension cord (Digi part number DC-ANT-E-24DP) with .5dB loss to separate the antenna from the product.. Caution: This Part 15 radio device operates on a non-interference basis with other devices operating at this frequency when using the antennae listed in the Antenna Specification table. Any changes or modification to the product not expressly approved by Digi International could void the user’s authority to operate the device.

GPIO General Information The NS7520 processor supports 16 general purpose I/O (GPIO) pins, some of which are reserved for specific functions and some of which can be customized. These pins fall into three categories:  Those labeled “Reserved” in the following table are dedicated to a specific use and must not be reprogrammed, or the unit may not operate correctly. Often, these pins are not connected to external interfaces.  Those labeled “Allocated” in the following table are exposed to an external interface and allocated to a specific use by the software but can be customized safely with code modifications.  Those labeled “Available” are exposed to an external interface, not controlled directly by the software, and can be customized. GPIO Registers Two registers, named PORTA and PORTC, govern the 16 GPIO pins. Each register is responsible for eight pins, and each GPIO pin uses the following four bits to completely describe its behavior:  Mode (CMODE)  Direction (CDIR)  Special function (CSF). This is only applicable to PORTC.  Data value The first three bits describe the functionality of the GPIO pin. The data bit provides the current value of the pin when read and allows control of the value of an output pin when written. 13 Digi Connect SP Hardware Reference In order to configure a pin as either a GPIO input or GPIO output, the corresponding bit positions in the appropriate register must be configured according to the information in the following table: GPIO Configuration Input Output – CMODE = 0 – CMODE = 0 – CDIR = 0 – CDIR = 1 – CSF = 0 – CSF = 0 Since each register controls 8 GPIO pins, it is safest to read the full 32 bit register, modify the bits corresponding to the pin, and then write the full 32 bits back. In this way, the behavior of other GPIO pins will be preserved. For more information regarding the format and programming of the GPIO registers, see the NS7520 Hardware Reference. GPIO Pin Use GPIO Pin Use Register Bit Category External Interface Description PORTA7 PORTA0 Reserved NA NA PORTC7 Reserved NA NA PORTC6 Allocated Used as a power indicator (always on). It could be reassigned as a general Connected to the purpose LED. It must remain a GPIO red LED output for the LED to operate correctly. The LED is lit when the signal is a logic "high." PORTC5 Available Connected to the It should be configured as a GPIO input. reset button. PORTC4 PORTC0 Reserved NA NA 14 LEDs General information The device server has two types of LEDs:  LEDs connected directly to GPIO pins on the processor and controlled directly in software  LEDs connected to other hardware components (normally the Ethernet hardware) and not directly programmable by the operating system The development kit supplies software to control the LEDs. This behavior can often be modified by manipulating the LED table in the BSP code. See gpio.c for details. As with any GPIO output, the GPIO register must be properly configured in order to assert values on the pin. The appropriate bits should be configured as:  CMODE = 0  CDIR = 1  CSF=0 About LEDs The device server has three LEDs:  The green LED is wired directly to the Ethernet hardware and indicates that a link has been established.  The yellow LED is wired directly to the Ethernet hardware and signals Ethernet activity.  The red LED is software programmable. It is wired to processor GPIO register bit PORTC6. The LED is wired to be active high. The development kit software is implemented by default so that this LED reflects "power" (and is, therefore, always lit). Flash General Information Digi Connect SP and Digi Connect Wi-SP device servers each have 4 MB of flash memory, which is controlled by chip select 0, located at 0x02000000. 15 Digi Connect SP Hardware Reference Memory Digi Connect SP and Digi Connect Wi-SP device servers each have 16 MB of SDRAM memory, which is controlled by chip select 1, located at 0x00000000 in the processor address space and aliased at 0x04000000 and 0x08000000. The application program (EOS) is loaded at address 0x08080000. Reset Button The device servers have a push button connected to a GPIO pin. This pin is named "/INIT." In the processor, the GPIO register bit associated with "/INIT" is PORTC5. The GPIO pin will read as high normally, and low when the button is pushed. See "Reset Button" on page 8 for the external location. 16 Specifications A P P E N D I X A Network Interfaces Digi Connect SP  RJ-45 connector  10/100Base-T  Half- and full-duplex support Digi Connect Wi-SP 17  Standard: IEEE 802.11b  Data Rate: Up to 11 Mbps with automatic fallback  WEP (64-bit and 128-bit encryption)  WPA (Wi-Fi Protected Access)/WPA2/802.11i  Frequency: 2.4 GHz  Modulation: CCK (11/5 Mbps), DQPSK (2 Mbps), DBPSK (1 Mbps)  Transmit power: 16 dBm typical  Receive sensitivity: – 1Mbps: -92 dBm – 2Mbps: -89 dBm – 5.5Mbps: -87 dBm – 11Mbps: -82 dBm  Antenna connector: RP-SMA  10/100Base-T auto-sensing  Half- and full-duplex support Digi Connect SP Hardware Reference Serial Interface One EIA-232/422/485 switch-selectable serial port with full modem control.
