There are two types of DMX cables, 3-pin or 5-pin, and they feature XLR type
connectors. This unit transmits from a 3-pin female connector on the back edge
of the unit. If your fixtures use 5 pin connectors, we recommend you acquire
a 3-pin male XLR to 5-pin female XLR adapter. Some fixtures use a reversed
signal scheme. This means the DATA - and DATA + pins are reversed. This unit
features a reversing switch on the back so as to accommodate those types
of fixtures. The table below shows the pin assignments for both normal and
reversed operation.

Channels should never overlap. If they do, this will result in erratic operation of
the fixtures whose starting address is set incorrectly. You can however, control-
multiple fixtures of the same type using the same starting address as long as
the intended result is that of uniform movement or operation. In other words, the
fixtures will be slaved together and all respond exactly the same.
When using multiple DMX devices, they should be connected together as a
chain of devices. The devices should be wired in a daisy chain fashion, meaning
the control cable will go from the controller to the first fixture and then to other
fixtures. Most fixtures have a DMX IN and a DMX OUT port for this purpose.
Do not split the control cable into a multiple run star arrangement with a cable
running from the controller directly to each fixture.

In controller mode, the last fixture of a DMX chain has to be “terminated”. This
prevents electrical noise from disturbing and corrupting the DMX control sig-
nals. To terminate the last fixture solder a 1/4 Watt, 120 Ohm resistor across the
DMX Termination
