Unpacking:
Every DJ Scan 250HP™ has been thoroughly tested and has been
shipped in perfect operating condition, there is no assembly neces-
sary. Carefully check the shipping carton for damage that may have
occurred during shipping. If the carton appears to be damaged, care-
fully inspect your unit for any damage and be sure all equipment nec-
essary to operate the unit has arrived intact. In case damage has been
found or parts are missing, please contact our toll free customer sup-
port number for further instructions, please do not return the unit to
your dealer.
Power Supply:
Before plugging your unit in be sure the source voltage in your area
matches the required voltage for your American DJ® DJ Scan 250HP.™
The American DJ® DJ Scan 250HP
™
is available in a 120v and 220v ver-
sion. Because line voltage may vary from venue to venue, you should
be sure to plug your unit into a matching wall outlet before attempting
to operate you controller.
Data Cable (DMX Cable) Requirements:
Your controller and packs require a standard 3-pin XLR connector for
DMX data input and DMX data output (Figure 1). If you are making your
own cables be sure to use standard two conductor shielded cable (This
cable may be purchased at almost all pro 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 can not be “Y-d” or split.
Notice: 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.

Notice: Be sure to follow figures two and three when making your own
cables.
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 connected 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 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.
