Control and Data Connections

Sensor3 racks support a variety of control and data connections on the CEM3 backplane.

CEM3 backplanes have connectors for:

• Two DMX512 Cables (Universes)

• External Panic Circuit Activation and Indication

• Remote Redundant Tracking selection switch (Dual Backplane Only)

• Ethernet Network

• Station Wiring

Dual and Single Backplane Differences

To use dual control modules your rack must be fitted with a dual tracking backplane. Racks

without dual tracking may have an empty second slot, or use the second slot to hold a

network switch. The exception is ESR3-12 racks, which only have space for a single control

module.

Racks with a dual backplane also have a three position switch which allows manual

switching of control of the rack to the top CEM3, the bottom CEM3, or for automatic

switching between the two.
