Hi guys

I have a problem with DMC elevator. I can't stablish comunication between CLC and FAST. Also I have fixtures TURNED OFF, calls buttons activate and deactivate. This is the first time I have communication problems with this elevator.

I checked R5 and R6 resistors on 6300BP4 CLC are not working, it looks an open circuit if you read with multimeter. Does anyone know the R5 and R6 nominal values to replace?

Regards
