This button is used to exit menus and to scroll
backwards through certain menus only.
2. Up Button -
This button is used to scroll forward when navigating
through the system menu.
3. Down Button -
This button is used to scroll backwards when navi-
gating through the system menu.
4. Software Update Input Jack -
This jack is used to update the
latest software version into the unit.
5. Enter Button -
This button is used to select and confirm a func
-
tion when working in the system menu. It is also used to exit certain
menus.
6. XLR Output Jack -
This jack is used to transmit the incoming
DMX signal to another DMX fixture, or transmit a Master/Slave signal
to the next Accu LED MH 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 11.
7. XLR DMX Input Jack -
This jack is used to receive an incoming
DMX signal or Master/Slave signal.
8. Power Switch -
This switches the power to the fixutre “On” and
“Off”.
9. Power Cord Inlet/Fuse Holder -
This unit is equipped with a remov-
able I.E.C. power cord. Be sure to only use the power cord included
with the unit, this cord is designed to match the electrical require-
ments of the unit. Other cords may cause the unit to overheat or mal-
function. Voltage may vary from venue to venue, when connecting this
unit to a power supply be sure to connect to a matching power outlet.
Never use this fixture if the ground prong has been removed or broken
off. The ground prong is designed to reduce the risk of fire or electrical
shock in the event the unit suffers from an internal short.
The fuse housing stores a 8 amp (4 amp 220v) GMA protective fuse.
Never defeat the fuse, the fuse is designed to protect the electronics in
the event of severe power fluctuations. Always be sure to replace the
fuse with an exact match as the one being replaced, unless otherwise
told to do so by an authorized American DJ
®
service technician.
Power Supply:
Before plugging your unit in, be sure the source volt-
age in your area matches the required voltage for your American DJ

Accu LED MH.™ The American DJ
®
Accu LED MH is available in a
120v and 220v version. Because line voltage may vary from venue to
venue, you should be sure your unit voltage matches the wall outlet
voltage before attempting to operate you fixture. Also be sure to only
use the included I.E.C. power cable supplied with the unit, this cable
matches the voltage and current requirements of the unit.
DMX-512:
DMX is short for Digital Multiplex. This is a universal pro-
tocol used by most lighting and controller manufactures as a form of
communication between intelligent fixtures and controllers.
A DMX
controller sends DMX data instructions from the controller to the fix
-
ture. 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. Therefore, the first fixture controlled
by the controller could be the last fixture in the chain. 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.
Data Cable (DMX Cable) Requirements (For DMX
and Master/Slave Operation):
The Accu LED MH
can be controlled via DMX-512 protocol. The Accu
LED MH is a nine channel DMX unit. The DMX
address is set electronically using the controls on
the side panel of the unit. Your unit and your DMX
controller require a standard 3-pin XLR connec-
tor for data input and data output (Figure 1). If you
are making your own cables, be sure to use standard two conductor
