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 90-120 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 socket 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 behav-
ior.

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.

5-Pin XLR DMX Connectors.
Some manufactures use 5-pin XLR
connectors for DATA transmission in place of 3-pin. 5-pin XLR fixtures
may be implemented in a 3-pin XLR DMX line. When inserting stan-
dard 5-pin XLR connectors 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.

Mega Flash DMX™ Operating Instructions
Power Supply:
This unit is available only in 120v. Before plugging
your unit in be sure the source voltage in your area matches the
required voltage for your American DJ
®
Mega Flash DMX.™
General Operation:
This fixture is designed to operate as a stand
alone, sound-active unit, or in a Master/Slave configuration. It can
also operate via DMX controller. The Mega Flash DMX™ is ready to
be plugged in out of the box.
Duty Cycle:
Because the Mega Flash DMX™ can be used for continuous output
(ie while simulating lightning), it can build up intense heat. Due to the
build up of intense heat the unit should not run for 15 minutes con-
tinuously. After 15 minutes of continuous use, allow the unit to cool
for about fifteen minutes, this will greatly increase the lamp life and
insure product longevity.
Operating Modes:
Stand Alone and Sound Active Modes:
To run the strobe in stand alone mode, dipswitches #9 and #10 must
be in the “off” position. In stand alone mode the unit will function
as a normal strobe light. Rate (speed), and intensity (brightness),
are set directly on the unit. Note that these settings are made using
the knobs on the back of the unit. Once the settings are made they
can only be changed by physically adjusting the knobs on the unit.
Be aware of this if you plan on installing your strobe in a permanent
application, if your are not satisfied with your settings you will have to
physically remove the unit and adjust the knobs.
In sound active mode, dipswitch #9 must be in the “on” postion. The
dimming will still be controlled by the knob on the back of the unit.
But the beat of the music will control the flash speed. Note that these
settings are made using the knobs on the back of the unit. Once the
settings are made they can only be changed by physically adjusting
the knobs on the unit. Be aware of this if you plan on installing your
strobe in a permanent application, if your are not satisfied with your
settings you will have to physically remove the unit and adjust the
knobs.
Universal DMX Control:
This mode allows you to use a universal
DMX-512 controller such as the American DJ
