Set Up:
Power Supply:
Before plugging your unit in be sure the source
voltage in your area matches the required voltage for your American
DJ
DP-DMX-20L.™ The DP-DMX-20L™ is available in a 115v and
®
230v version. Because line voltage may vary from venue to venue, you
should be sure to plug your power supply into a matching wall outlet
before attempting to operate you controller.
Data Cable (DMX Cable) Requirements:
Your power pack and your controller
require a standard 3-pin XLR connector
for data input and data output (Figure
1). If you are making your own cables
be sure to use standard two conductor
shielded cable (This cable may be pur-
chased at almost all pro sound and light-
ing stores). Your cables should be made
with a male and female XLR connector
on either end of the cable. Also, remem-
ber that DMX cable must be daisy
chained and can not be "Y"ed or split.

Notice:
Do not use the ground lug on the XLR connector. Do
not connect 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
POWER
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 behav-
ior.

Product Description:
The DP-DMX20L, ™ is 1, 2, or 4 channel DMX Dimmer Pack. This
pack can serve as a stand alone chaser or a DMX dimmer pack.
This pack is designed for zero-crossing circuitry which protects

aginst inductive loads, so it is safe for use with all lighting effects
that include transformers such as pin spots. Each channel comes

with two 3-prong Edison sockets inputs for a total of eight. This
unit features XLR female and male connection for DMX compat-
ability. Each channel is equiped with a fuse for each channel,
and a maximum output load of 10A per channel or 20A total.
This revision of our popular DP-DMX20™ has a great new case
POWER
design that makes it great for permanent or mobile applications.
