UB 6H DMX Set Up
ADJ Products, LLC - www.adj.com - UB 6H User Manual Page 7
Power Supply: The ADJ UB 6H contains an automatic voltage switch, which will automatically 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 UB 6H can be controlled via
DMX-512 protocol. The UB 6H has 4 DMX channel modes; please see the Channel Mode sections of
this manual for the different modes. 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 connec-
tor at 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.
