  Digital IO Board


This is the pinout for the 40 pin headers on the IO Board. Pin 1 is the pin nearest the Excalibur board, and furthest from the yellow IC on the top (it may be marked with an 'H'). Header 1 is nearest the Excalibur board, and uses the Verilog pins IOBOARD_A[0:7] and IOBOARD_B[0:7]. Header 2 uses IOBOARD_A[8:15] and IOBOARD_B[8:15].


  IR Module

This is a PIC-26043SM Farnell order code 139-877. It takes 5V on pin 3, GND on pin 2 and gives an open collector output on pin 1. The output is also inverted, and so is pulled to ground (sinks current) when a IR signal is received. It thus needs a 470 Ohm pull-up resistor to 5V to be able to interface it to TTL logic.
