Wallboard (Readerboard) Question - Interface Protocol


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 ?

Hi John,

Wondering if you had any luck find the protocal specification/s for communicating with wallboards?? I have recently acquired a couple of different wall boards, and i am seeking the same type of information for either the QMaster, CallSca or Navigator protocols to talk to a LUA MM 23213, Advatel TCD226R or a Symon MM232.

Any help appreciated...

Regards Neil
