I open the switch and took another look see.

The DXCPU-68K card in my unit does not have a port marked maintenance.

It has the dip switches you mentioned earlier - all in the off position

It has four ports (1)RS232 1 (2)RS232 (3)Relay 1 & 2 (4) Relay 3 & 4


Thanks - Paul

You are plugged in the maintenance port right, it is for programming. It is the bottum plug on the CPU. If your not in that one try it.
