Hello everyone. Yesterday my PC Access Installer version 1.9A quit communicating with my OnQ 1050 panel. Main panel and serial interface board seem to be working. I get a blink on the RCV light on the serial board when I trying to communicate with the board, but no response. PC Access has worked years with no problem. I checked the keypad and the installer code and PC access code are correct. The problem started after a service tech installed a new 4G cellular transmitter to replace my old 3G transmitter
Regards,
Dave
