Deco 250™
Power Supply:
Before plugging your unit in, be sure the source volt-
age in your area matches the required voltage for your American DJ
Deco 250.™ The American DJ
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 fixture.
DMX-512:
DMX is short for Digital Multiplex. This is a universal
protocol 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
travels from fixture to fixture via the DATA "IN" and DATA "OUT" XLR
terminals 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 single
controller, as long as all fixtures and the controller are DMX compliant.
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.
Dip-switches 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 used for special functions such as sound activation.
Each dipswitch has a preset value. A specific DMX address is set by
®
combining the dipswitches that sum your desired value. For example:
To achieve a DMX address of 21, combine dipswitches 1, 3, and 5.
Sense dipswitch 1 has a value of 1, dipswitch 3 has a value of 4, and
dipswitch 5 has a value of 16, the combination of the create a DMX
value of 21.
Set DMX address 21:
Dipswitch # 1 = 1
Dipswitch # 3 = 4
Dipswitch # 5 = 16

The DMX address is set on the back panel of the Deco 250™. Your unit
and your DMX controller require a standard 3-pin
XLR connector for data input and data output
(Figure 1). If you are making your own cables, be
SOUND
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 figures two and three when making your own
cables. Do not use the ground lug on the XLR connector. Do not con-
