Communication Diagnostics
The PC109x control boards have communication status LEDs and a system status LED, which indicate the
current communication status.
For CIM diagnostic LEDs, refer to page 78.
Communication Status LEDs
The CA250B, CA4500B, CA8500B, EC1500B, EC2500B, CB-485, and CPB-10-2 have communication LEDs for
diagnostics and troubleshooting. The table below outlines the LED and its diagnostic function. When calling
Keyscan technical support, indicating the LEDs state assists our technicians in isolating potential difficulties.
