American DJ IMAGE 8 DMX - Manual (Page 4)

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

Image 8 DMX.™ The American DJ

Image 8 DMX ™ 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 attempt-
ing 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

Image 8 DMX™ Control & Functions
5. Dip Switches - These switches serve two functions. In master-
slave mode these switches are used to assign a specific head address.
In DMX mode these switches are used to assign a DMX address to the
unit. In DMX mode each switch corresponds to a specific value based
on binary code. See pages 8-9 for a detailed explanation of DMX
binary code.
6. XLR Output Jack - This female output jack is used to transmit the
incoming DMX signal to another DMX fixture, or transmit a Master/
Slave signal to the next Image 8 DMX™ in the chain. For best results
in DMX or Master/Slave mode terminate this jack if it is the last unit in
the chain. See “Terminator” on page 10.
7. XLR Input Jack - This male input jack is used to accept an incom-
ing DMX signal or Master/Slave signal.
8. Audio Sensitivity Knob - This adjusts the audio sensitivity of the
internal microphone (1). Turning the sensitivity knob in the clockwise
direction will increase the sensitivity to sound. Turning the knob in
the counter clockwise direction will decrease the fixture’s sensitivity
to sound. If the knob is turned completely in the counter-clockwise
direction the sound sensitivity function will turn off.
