4 Control Wiring Terminations
The DX3 system has inputs and outputs available for multiple protocols and control functions as
illustrated below.

4.1 DMX A & DMX B Connections
TB6 & TB7 are used to connect the DMX inputs. Note that the “OT” signals are to be used only when
connecting to Lehigh Electric manufactured consoles, as these are pins 4 & 5 of the standard XLR-5
connectors used for DMX. This “OT”, or “over-temp” is activated whenever any dimmer in the rack
exceeds its temperature limits, thus sending a signal to the console that there is an over-temp condition
in the rack.
