Power Supply - American DJ Mega Par Profile User Instructions

Mega Par Profile
ower Supply:
P The American DJ Mega Par Profile 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 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 Mega Par Profile can be controlled via DMX-512 protocol. The Mega
Par Profile 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 Profile. 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 figures 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.

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.

fixtures 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.
