DMX-512: DMX is short for Digital Multiplex. This is a universal protocol used as a form of communi-
cation 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 Encore LB15IP can be con-
trolled via DMX-512 protocol, and features multiple DMX channel modes. Your unit and your DMX
controller require a 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 termi-
nator 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.
