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.
A DMX network will be required if:
a) The fixture inside the enclosure requires a DMX control signal
b) You wish to monitor the enclosure using RDM
c) You wish to control the enclosure lamp relay over DMX
DMX Terminations
Pinout: (1) Ground, (2) Data -, (3) Data +.
DMX Connectors:
1 DMX IN from network
2 DMX OUT to luminaire (or to network
if not controlling luminaire)
3 DMX IN from luminaire
4 DMX OUT to network
If the enclosed fixture does not use DMX,
then connector (2) on the controller is
DMX OUT for the enclosure.
DMX Line Terminations
DMX cable runs must be terminated at
the far end of the cable run with a
termination resistor as detailed in the
DMX512 standard.
The individual fixtures installed inside the
Tempest enclosures must NOT be terminated.
It is recommended that any line termination is
done using the 3-pin terminal connector fitted
to the DEC3.2 control circuit board.
