I have a TAC 50 04 with a bad 6300VC1 board (or24-1) in the COP. What requirements need to be met to replace these boards? They are all connected to the CAN via ethernet cables, this particular one is identified as 24-4 and has the cartop inspection and access inspection plugged into it. I guess what I'm trying to say, is if i replace this board, how will the can know that it is 24-4 and that these are the inputs plugged into it? I understand they are not intelligent boards, but I have to assume they are addressed somehow for the CAN to determine what is plugged into it?
