We have an existing installation that we have recently upgraded for the customer. The set up was using a UCM with an RS232 daughter board to connect to a centralite system.
After upgrading the UCM to 7.XX there appears to be no communication out of the UCM.
When an RS232 communication is sent...- There is a flashing LED on the main board L10 L11 - NO flashing LED on the UCM D9 and D10
Am I correct in saying that the LED's D9 and D10 should flash when an RS232 communication is sent?
