Dmx Set Up - ADJ MINI DEKKER LZR User Instructions

DMX SET UP

Power Supply: The ADJ Mini Dekker LZR 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 correct 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 manufactures 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, when using several DMX fixtures try to use the shortest cable path possible. 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 Mini Dekker LZR
has two DMX channel modes; a 2 channel mode and 7 channel mode. The DMX address
is set electronically using the controls on the rear panel of the unit. Your unit and your DMX
controller require a approved DMX-512 110 Ohm Data cable for data input and data output.
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
professional sound and lighting stores). Your cables should be made with a male and
female XLR connector on either end of the cable. Also remember that DMX cable must be
daisy chained and cannot be split.
Notice: Be sure to follow figures two and three when making your own cables. Do not use the ground lug on the
XLR connector. Do not connect the cable's shield conductor to the ground lug or allow the shield conductor to
come in contact with the XLR's outer casing. Grounding the shield could cause a short circuit and erratic
behavior.
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 possibilities of erratic behavior.

Termination reduces signal errors and avoids
signal transmission problems and interference. It is
always advisable to connect a DMX terminal,
(Resistance 120 Ohm 1/4 W) between PIN 2 (DMX-
) and PIN 3 (DMX +) of the last fixture.
