Spare ETC Sensor CEM

The Control Electronics Module (CEM) is required for Sensor systems. The CEM sets dimmer levels, monitors system status and enters your changes to system configuration settings. A Sensor dimming system will not function without a properly installed CEM. For control input, the CEM has two DMX512 input ports, port A and port B. You can use them individually or make them work together. The CEM location varies by cabinet type.
