Power Supply
Power Supply: The ADJ UV LED Bar20 IR contains a automatic voltage switch, which will auto sense
the voltage when it is plugged into the power source. With this switch there is no need to worry about
the cor- rect power voltage, this unit can be plugged in anywhere.
DMX-512: DMX is short for Digital Multiplex. This is a universal protocol 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
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 using 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 UV LED BAR20 IR can be
controlled via DMX-512 protocol, and features multiple DMX channel modes. Your unit and your DMX
controller can operate with either a 3-pin or 5-pin XLR connector for data input and data output. 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 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.
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 connected 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 chances of erratic behavior.
5-Pin XLR DMX Connectors. Some manufacturers use 5-pin XLR connectors for DATA transmission
in place of 3-pin. 5-pin XLR fixtures may be implemented in a 3-pin XLR DMX line. When inserting
standard 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:

A DMX512 terminator reduces signal errors,
avoiding most signal reflection interference.
Connect PIN 2 (DMX-) and PIN 3 (DMX+) of
the last fixture in series with a 120 Ohm, 1/4 W
Resistor to terminate the DMX512.
