Dmx Setup - ADJ ENCORE LP18IP User Manual

DMX-512: DMX is short for Digital Multiplex. This is a universal protocol used as a form of commu-
nication 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 LP18IP can be con-
trolled via DMX-512 protocol, and features multiple DMX channel modes. Your unit and your DMX
controller require either a 3-pin (for EU markets) or 5-pin (for US markets) 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 pro lighting stores). Your cables should be
made with a male XLR connector at one end and a female XLR connector on the other. Also remem-
ber 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 ter-
minator 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 transmis-
sion in place of 3-pin. 5-pin XLR fixtures may be implemented in a 3-pin XLR DMX line. When insert-
ing 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:
