Power Supply:
Before plugging your unit in be sure the source volt-
age in your area matches the required voltage for your American DJ
®
DJ Roller.™ The American DJ
®
DJ Roller
™
is available in a 120v and
220v version. Because line voltage may vary from venue to venue,
you should be sure your unit voltages matches the wall outlet voltage
before attempting to operate you fi xture.
Data Cable (DMX Cable) Requirements
(For DMX Operation Only and Master-
Slave):
The DJ Roller™ may be controlled via
DMX-512 protocol. Your unit and your DMX con-
troller require a standard 3-pin XLR connector
for data input and data output (Figure 1). If you
are constructing your own cables, be sure to
use standard two conductor shielded cable as
detailed in fi gure two (This cable may be pur-
chased 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 may
not be split.
Notice:
Be sure to follow fi gure three when making your own cables.
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.

DMX Addressing
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 connector of the last
unit in your daisy chain to terminate the line. Using a cable terminator
(ADJ part number ZDMX/T) 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.
Figure 4
DMX is short for Digital Multiplex. This is a universal binary language
used as a form of communication between intelligent fixtures. Each
dip switch represents a binary value.
Dip Switch 1 address equals 1
Dip Switch 2 address equals 2
Dip Switch 3 address equals 4
Dip Switch 4 address equals 8
Dip Switch 5 address equals 16
Dip Switch 6 address equals 32
Dip Switch 7 address equals 64
Dip Switch 8 address equals 128
Dip Switch 9 address equals 256
Each dip switch has a preset value, a desired DMX address is set by
combining the dip switches that will create your desired value. For
example: To achieve a DMX address of 21, combine dip switches 1, 3,
and 5. Sense dip switch 1 has a value of 1, dip switch 3 has a value
of 4, and dip switch 5 has a value of 16, the combination of the create
a DMX value of 21.
Set DMX address 21:
Set DMX address 201:

3 = 4
4 = 8
5 = 16
7 = 64
