Power Supply: The American DJ Mega Par Prole contains a auto-

matic 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 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

different 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 can be controlled via DMX-512 protocol. The Mega

Par Prole has 7 DMX channel modes, please see page 9 for the different

modes. The DMX address is set on the back panel

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

controller require a standard 3-pin XLR connec-

tor 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.
