P
ower Supply:
The Elation EPAR QA 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 pro-
tocol used by most lighting and controller manufactures as a form of
communication between intelligent fixtures and controllers. A DMX
controller sends DMX data instructions from the controller to the fix-
ture. 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 compli-
ant. 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 EPAR QA has 6 DMX Channel Modes. 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.

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 con-
nected 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.

Some manufactures use 5-pin DMX-
512 data cables for DATA transmission in place of 3-pin. 5-pin DMX
fixtures may be implemented in a 3-pin DMX line. When inserting
standard 5-pin data cables 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.
