DMX Connections
DMX refers to USITT DMX512, a commonly used control protocol in the entertainment industry,
running over RS485. Consult USITT DMX installation guidelines when laying out a system, or
employ a qualified DMX system integrator.
Note that DMX is optional – in many applications it is not required, and need not be connected.
DMX IN – Connect incoming DMX to the 2-part 3-pin terminal on the DEC3 control circuit board so
labeled.
Pinout: (1) Ground, (2) Data -, (3) Data +.
DMX THRU – there are two DMX pass-through terminals – one for a fixture inside the enclosure,
the other to run to the next DMX device in the network. Pinout: same as DMX IN.

DMX Line Termination
DMX cable runs must be terminated at the far end of the cable run with a termination resistor as
detailed in the DMX standard. This is particularly important for satisfactory operation of DMX/RDM
