OPTOMUX Protocol

The OPTO 22 format is RS-422, Full-Duplex, 1200 BAUD, 8 bit, no parity, and 1 stop bit. The message format follows the OPTOMUX two pass protocol. The UNIPRO sends messages to set up the events board per the events partition, activate the appropriate outputs, and reads the input conditions. The UNIPRO initiates messages on this buss and waits ½ second for a reply.
