between 120v ~ 240v. Be sure to only use the included I.E.C. power
cable supplied with the unit, this cable matches the current require-
ments of the unit.
DMX-512:
DMX is short for Digital Multiplex. This is a universal pro-
tocol used as a form of communication between intelligent fixtures
and controllers. A DMX controller sends DMX data instructions from
the controller to the fixture. DMX data is sent as serial data that trav-
els from fixture to fixture via the DATA "IN" and DATA "OUT" XLR ter-
minals 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. 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 Operation):
The Mega Bar LED™ can be controlled via DMX-512 protocol. The Mega
Bar LED™ can be a two, three, four, six, seven or 11 channel DMX unit.
The DMX address is set on the back panel of the Mega Bar LED™. 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 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.

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.

may be implemented in a 3-pin XLR DMX line. When inserting stan-
dard 5-pin XLR connectors in to a 3-pin line a cable adaptor must be
used, these adaptors are readily available at most electric stores. The
chart below details a proper cable conversion.
