Mega Bar 50RGB RC Set Up
Power Supply: The ADJ Mega Bar 50RGB RC contains an automatic voltage switch, which will auto-
matically sense the voltage when it is plugged into the power source. With this switch, there is no
need to worry about the correct power voltage, and this unit can be plugged in anywhere.
DMX-512: DMX is short for Digital Multiplex. This is a universal protocol that is 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 travels from fixture
to fixture via the DATA "IN" and DATA "OUT" XLR terminals located on all DMX fixtures (most control-
lers only have a DATA "OUT" terminal).
DMX Linking: DMX is a language allowing all makes and models of different manufacturers to be
linked together and operate from a single controller, as long as all fixtures and the controller are DMX
compliant. To ensure proper DMX data transmission, try to use the shortest cable path possible
when linking several DMX fixtures. 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 50RGB RC can be
controlled via DMX-512 protocol. The Mega Bar 50RGB RC has 7 DMX channel modes; please see
the Channel Mode sections of this manual for the different modes. The DMX address can be con-
figured using the control panel on the rear of the unit. Your unit and your DMX controller require an
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 XLR connector on one end of the cable and a female XLR
connector at the other. Also remember that DMX cable must be daisy chained and cannot be split.
