Dmx Set Up - ADJ MEGA BAR RGBA User Manual

D M X S E T U P
Power Supply: The ADJ Mega Bar RGBA contains an automatic voltage switch, which will automati-
cally 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, this unit can be plugged in almost 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 in-
structions 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 controllers
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 together. 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 RGBA can be con-
trolled via DMX-512 protocol, and features 7 selectable DMX channel modes, as detailed in the DMX
Traits section of this manual. The DMX address is set on the back panel of the fixture. Your unit and
your DMX controller require a standard 3-pin XLR connector 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 XLR connector at one end and a female XLR connector at the
other. Also remember that DMX cable must be daisy chained and cannot be split.
