Having a problem with a 401 cop2 board. Green led transmit not coming on. Checked for 12 volt to board and have it. Tried swapping board and chips. Still have the same problem. I see data wires on the print but I not sure which ones I need to concentrate on. Any suggestions??? 👍

Also you know you can use a fluke meter on Hz to see if you have communication across data lines. Think it was 1200 or 1800 Hz.
