Power Supply: The American DJ Mega Par Prole System contains

a automatic voltage switch, which will auto sense the voltage when it is

plugged into a 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 pro-

tocol 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 trav-

els from fixture to fixture via the DATA “IN” and DATA “OUT” XLR ter-

minals 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

dierent manufactures to be linked together and operate from a single

controller, as long as all xtures 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 Mega Par Prole System can be controlled via DMX-512 protocol.

The Mega Par Prole System has 3 DMX channel modes, please see

page 9 for the dierent modes. The DMX address is set on the back panel

of the Mega Par Prole System. Your unit and your

DMX controller require a standard 3-pin XLR con-

nector for data input and data output (Figure 1). 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 pro 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 gures two and three when making your own

cables. Do not use the ground lug on the XLR connector. Do not con-

nect 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 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.

5-Pin XLR DMX Connectors.

Some manufactures use 5-pin DMX-

512 data cables for DATA transmission in place of 3-pin. 5-pin DMX

xtures may be implemented in a 3-pin DMX line. When inserting stan-

dard 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.
