Assigning DMX Address:
Each dipswitch has a preset value. A spe-
cific DMX address is set by combining the dipswitches that sum your
desired value. For example: To achieve a DMX address of 7, combine
dipswitches 1, 2, and 3. Since dipswitch 1 has a value of 1, dipswitch
2 has a value of 2, and dipswitch 3 has a value of 4, the combination
of the three create a DMX value of 7. (See example below).
Set DMX address 1:
Set DMX address 7:
Dip-switches # 1 = 1
Dip-switches # 1 = 1
2 = 2
3 = 4
= 7
Data Cable (DMX Cable) Requirements (For DMX and Master/Slave
Operation):
The Mini Emerald Beam™ can be controlled via DMX-512
protocol. The Mini Emerald Beam™ is a two channel DMX unit. The
DMX address is set on the rear panel of the Mini Emerald Beam.™
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 con-
nector 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 figures two and three when making your own
cables. 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.

Termination reduces signal errors and
avoids signal transmission problems

to connect a DMX terminal, (Resistance
120 Ohm 1/4 W) between PIN 2 (DMX-)
and PIN 3 (DMX +) of the last fixture.

Power Supply:
Before plugging your unit in, be sure the source volt-
age in your area matches the required voltage for your American DJ

is 120v
only. 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 fixture.
DMX-512:
DMX is short for Digital Multiplex. This is a universal pro-
tocol used as a form of communication between intelligent fixtures
and controllers.
A DMX controller sends DMX data instructions from
the controller to the fixture. DMX data is sent as serial data that trav-
els from fixture to fixture via the DATA “IN” and DATA “OUT” XLR ter-
minals located on all DMX fixtures (most controllers only have a DATA
“OUT” terminal).
DMX Linking:
DMX is a language allowing all makes and models of
different manufactures to be linked together and operate from a sin-
gle controller, as long as all fixtures and the controller are DMX com
-
pliant.
To ensure proper DMX data transmission, when using several
DMX fixtures try to use the shortest cable path possible. The order
in which fixtures are connected in a DMX line does not influence the
DMX addressing. For example; a fixture assigned a DMX address of 1
may be placed anywhere in a DMX line, at the beginning, at the end,
or anywhere in the middle. When a fixture is assigned a DMX address
of 1, the DMX controller knows to send DATA assigned to address 1
to that unit, no matter where it is located in the DMX chain.
Dipswitches in DMX mode:
This unit uses dipswitches to assign a
DMX address. Each dipswitch represents a binary value.
Dipswitch 1 address equals 1
Dipswitch 2 address equals 2
Dipswitch 3 address equals 4
Dipswitch 4 address equals 8
Dipswitch 5 address equals 16
Dipswitch 6 address equals 32
Dipswitch 7 address equals 64
Dipswitch 8 address equals 128
Dipswitch 9 address equals 256
Dipswitch 10 - Some units omit dipswitch 10. When a unit does
include dipswitch #10, it is usually used for special functions such as
