Power Supply:
Before plugging your unit in, be sure the source
voltage in your area matches the required voltage for your American

has a user
selectable voltage switch Because line voltage may vary from venue
to venue, you should be sure your unit voltage matches the wall outlet
voltage before attempting to operate you fixture.
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 as-
signed 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):
The X-Move LED™ can be controlled via DMX-512 pro-
tocol. The Electra LED DMX™ is be a three chan-
nel DMX unit. The DMX address is set using the
dipswitches on the bottolm of the unit. Your unit
and your DMX controller require a approved DMX-
512 110 Ohm Data cable 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 professional sound and lighting
Figure 1
stores). Your cables should be made with a male and female XLR con-
nector 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.
