Operator Manual

For UDR systems, the address of the 942-200-80 Communications board in the UDR must be set 4040 and the baud rate must be set to 4800 baud. If the wiring of the Communications option board to the P2 connector is suspected, a loop test can be performed as described in "Loop Test Mode". The instruction manual for the Communications option board (P/N 942-200-80-1) contains information on how to set up the serial board in the UDR.

Firmware Version

This system requires a PROM for operation. For the part number and the latest revision of the PROM, see the Factory Test Data Sheet. This Manual has been prepared for use with the P/N 227LNK, Rev. 2, PROM.
