User Instructions
The LSC® PP-DMX20L™ is controlled via a standard DMX controller
such as the LSC® Show Designer,™ or the LSC® DMX-Operator.™ This
unit allow you to control special effect lighting, that normally could not
be controlled, by a DMX controller. With this revision to our popular PPDMX20™ we have eliminated confusing dipswitches and replaced them
with an easy to use digital switching device that incorporates the use of
an easy to read LCD display.

Power Supply: Before plugging your unit in be sure the source
voltage in your area matches the required voltage for your LSC® PPDMX20L.™ The PP-DMX20L™ 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 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”ed or split.
Notice: Do not use the ground lug on the XLR connector. Do
not connect the cableʼs shield conductor to the ground lug or allow
the shield conductor to come in contact with the XLRʼs 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 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.

Product Description:
The PP-DMX20L,™ is 1, 2, or 4 channel DMX Power Pack. This pack
can serve as a stand alone chaser or a DMX power pack. This pack
is designed for zero-crossing circuitry which protects against inductive
loads, so it is safe for use with 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 compatibility. Each channel is equipped
with a fuse for each channel, and a maximum output load of 6A per
channel or 15A total. This revision of our popular PP-DMX20L™ has
a great new case design that makes it great for permanent or mobile
applications.
