Resurrecting this thread since I got my hands on an Omnikey/Ultra.
Mine is from 1990, the DIP switches are not at the back, but on top, under the "Omnikey/Ultra" moniker.
It has suffered some abuse. The previous owner removed the connector for the detachable cable (I assume it was a PS/2 connector?) and replaced it with a DIN5 cable, soldered directly to the board.
The board has a connector on it with 6-pins, but when soldering in the new cable, he only attached 4 wires.
I'd like to try and restore this unit to its original state and need to know if all 6-pins should be connected, and how.
A pinout and/or pictures will be great!
Can anyone help?
