RGB 3C IR DMX Set Up
Power Supply:
Before plugging your unit in, be sure the source volt-
age in your area matches the required voltage for your ADJ RGB 3C IR.
The ADJ RGB 3C IR is 120v only. Only use the included power supply
to power RGB 3C IR.
DMX-512:
DMX is short for Digital Multiplex. This is a universal pro-
tocol used by most lighting and controller manufactures as a form of
communication between intelligent fixtures and controllers. A DMX
controller sends DMX data instructions from the controller to the fix-
ture. DMX data is sent as serial data that travels from fixture to fixture
via the DATA “IN” and DATA “OUT” XLR terminals located on all DMX
fixtures (most controllers only have a DATA “OUT” terminal).
DMX Linking:
DMX is a language allowing all makes and models of
different manufactures to be linked together and operate from a single
controller, as long as all fixtures and the controller are DMX compli-
ant. To ensure proper DMX data transmission, when using several
DMX fixtures try to use the shortest cable path possible. The order
in which fixtures are connected in a DMX line does not influence the
DMX addressing. For example; a fixture assigned a DMX address of 1
may be placed anywhere in a DMX line, at the beginning, at the end,
or anywhere in the middle. Therefore, the first fixture controlled by
the controller could be the last fixture in the chain. When a fixture is
assigned a DMX address of 1, the DMX controller knows to send DATA
assigned to address 1 to that unit, no matter where it is located in the
DMX chain.
Data Cable (DMX Cable) Requirements (For DMX and Master/Slave
Operation):
Your DMX controller require a standard 3-pin XLR connec-
tor for data input and data output (Figure 1). We recommend Accu-Cable
DMX cables. If you are making your own cables, be
sure to use standard 110-120 Ohm shielded cable
(This cable may be purchased at almost all pro
lighting stores). Your cables should be made with
a male and female XLR connector on either end of
the cable. Also remember that DMX cable must be
daisy chained and cannot be split.

Notice:
Be sure to follow figures two and three when making your own
cables. Do not use the ground lug on the XLR connector. Do not con-
nect the cable’s shield conductor to the ground lug or allow the shield
conductor to come in contact with the XLR’s outer casing. Grounding
the shield could cause a short circuit and erratic behavior.

Special Note: Line Termination.
When longer runs of cable are
used, you may need to use a terminator on the last unit to avoid erratic
behavior. A terminator is a 110-120 ohm 1/4 watt resistor which is con-
nected between pins 2 and 3 of a male XLR connector (DATA + and
DATA -). This unit is inserted in the female XLR connector of the last
unit in your daisy chain to terminate the line. Using a cable terminator
(ADJ part number Z-DMX/T) will decrease the possibilities of erratic
behavior.
