I have a bunch of "CallScan" (now QPC) wallboards which were previously used with VU-ACD software (Nortel platform).
They are 26x2 LED, and display "CallScan 7415 V1 ID:25 Multi Line Wallboard V1.2" when powered. They appear to just local-echo back the output sent to the RS-232/485 ports.
Would anyone happen to know a protocol specification for these so that I can write output to them?
Does anyone know what these were before they were rebadged by CallScan ?
