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
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.

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 4 address equals 8
Dip Switch 5 address equals 16
Dip Switch 6 address equals 32

Power Supply: Before plugging your unit in, be sure the source volt-
age in your area matches the required voltage for your American DJ®
Alpha Moon.™ The American DJ® Alpha Moon
™
is available in a 120v
and 220v version. Because line voltage may vary from venue to venue,
be sure to plug your unit into a matching wall outlet before attempting
to operate.
Data Cable (DMX Cable) Requirements (For DMX Operation
Only and Master-Slave): The Alpha Moon can be controlled via
DMX-512 protocol. The American DJ® Alpha Moon™ is a three chan-
nel DMX unit. The DMX address is set on the
front panel of the Alpha Moon. Your unit and your
DMX controller require a standard 3-pin XLR con-
nector 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 split.
Notice: Be sure to follow 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.
