AC Power
This fixture accepts an input of 100~240 VAC, 50/60 Hz. Before powering on the unit, make sure
the line voltage to which you are connecting it is within the range of accepted voltages. Also
make sure that the fixtures you are plugging into the DMX-4 LED match the input voltage.
Input voltage equals output voltage.
To determine the power requirements for a particular fixture, see the label affixed to the back
plate of the fixture or refer to the fixture’s specifications chart. A fixture’s listed current rating
indicates its average current draw under normal conditions.
Always connect the fixture to a switched circuit. Never connect the fixture to a rheostat
(variable resistor) or dimmer circuit, even if the rheostat or dimmer channel is used only
as a 0 to 100% switch.
Always connect the fixture to a circuit with a suitable electrical ground.
Notes on “Switch” Operation
Dimmer/switch packs are primarily intended for lamp-based PAR cans. Connecting a fixture
equipped with an electronic (switching) power supply to a dimmer/pack switch may damage the
fixture or make it work erratically.
The improved DMX-4 LED’s design now allows you to switch on and off loads equipped with
electronic power supplies, such as LED-based luminaries or laser fixtures. However, the DMX-4
LED must be in “switch” mode before connecting this type of loads to it. Please see the
instructions on how to set the DMX-4 LED in switch mode below.
Always make sure that the DMX-4 LED is in switch mode before connecting a load
equipped with an electronic power supply to it. Doing otherwise could damage the load.
Changing between “Dimmer” and “Switch”
The DMX-4 LED has two different methods for controlling the output of the four (4) channels. This
must be set by the user via the control panel.
Please see the steps below for this procedure.
1. Unplug any units from the four output channels.
2. Plug the DMX-4 LED into power.
3. Press <MODE> until ~ appears on the LED display.

DMX Primer
There are 512 channels in a DMX connection. A fixture capable of receiving DMX will require one
or a number of sequential channels. The user must assign a starting address on the fixture that
indicates the first channel reserved in the controller. There are many different types of DMX
controllable fixtures and they all may vary in the total number of channels required. Choosing a
start address should be planned in advance. Channels should never overlap. If they do, this will
result in erratic operation of the fixtures whose starting address is set incorrectly. You can
however, control multiple fixtures of the same type using the same starting address as long as the
intended result is that of unison movement or operation. In other words, the fixtures will all
respond exactly the same.
DMX fixtures are designed to receive data through a daisy chain. A daisy chain connection is
where the DATA OUT of one fixture connects to the DATA IN of the next fixture. The order in
which the fixtures are connected is not important and has no effect on how a controller
communicates to each fixture. Use an order that provides for the easiest and most direct cabling.
Connect fixtures using shielded two conductor twisted pair DMX data cable with three pin XLR
male to female connectors. The shield connection is pin 1, while pin 2 is Data Negative (S-) and
pin 3 is Data positive (S+).
Fixture Linking (Daisy Chain)
You will need a daisy chain to run light shows of one or more fixtures using a DMX controller or to
run synchronized shows on two or more fixtures set to a master/slave operating mode. The
combined number of channels required by all the fixtures on a daisy chain determines the number
of fixtures the data link can support.
To comply with the EIA-485 standard, do not connect more than 32 fixtures on one daisy
chain. Connecting more than 32 fixtures on one daisy chain without the use of a DMX
optically-isolated splitter may result in deterioration of the digital DMX signal.
Maximum recommended cable distance: 500 m (1640 ft)
Maximum recommended number of fixtures on a daisy chain: 32
Data Cabling
To link fixtures together you must obtain data cables. You can purchase CHAUVET® certified
DMX cables directly from a dealer/distributor or construct your own cable. If you choose to create
your own cable please use data-grade cables that can carry a high quality signal and are less
prone to electromagnetic interference.
DMX Data Cable
Use a Belden© 9841 or equivalent cable which meets the specifications for EIA RS-485
applications. Standard microphone cables cannot transmit DMX data reliably over long distances.
The cable must have the following characteristics:
Type:
shielded, 2-conductor twisted pair
30 pF/ft
Maximum capacitance between conductors:
Maximum capacitance between conductor and shield:
Maximum resistance:
Nominal impedance:
55 pF/ft
20 ohms/1000 ft
100 ~ 140 ohms

Do not allow contact between the common and the fixture’s chassis ground. Grounding
the common can cause a ground loop, and your fixture may perform erratically. Test
cables with an ohm meter to verify correct polarity and to make sure the pins are not
grounded or shorted to the shield or each other.
Setting the Starting Address
This DMX mode enables the use of a universal DMX controller device. Each fixture requires a
start address from 1~512. A fixture requiring one or more channels for control begins to read the
data on the channel indicated by the start address. For example, a fixture that uses six DMX
channels and was addressed to start on DMX channel 100, would read data from channels: 100,
101, 102, 103, 104, and 105. Choose start addresses so that the channels used do not overlap,
and note the start address selected for future reference.
If this is your first time addressing a fixture using the DMX control protocol, we suggest jumping
to the “Appendix” section and reading the heading “DMX Primer”. It contains very useful
information that will help you understand its use.

General Maintenance
To maintain optimum performance and minimize wear, fixtures should be cleaned frequently.
Usage and environment are contributing factors in determining frequency. As a general rule,
fixtures should be cleaned at least twice a month. Dust build up reduces light output performance
and can cause overheating. This can lead to reduced lamp life and increased mechanical wear.
Be sure to power off fixture before conducting maintenance.
Unplug fixture from power.
Use a vacuum or air compressor and a soft brush to remove dust collected on external
vents.
Clean all lenses when the fixture is cool with a mild solution of glass cleaner or
Isopropyl Alcohol and a soft lint free cotton cloth or lens tissue.
Apply solution to the cloth or tissue and drag dirt and grime to the outside of the lens.
Gently polish optical surfaces until they are free of haze and lint.
Always dry the parts carefully after cleaning them.
Never spin a fan using compressed air.

#). Products returned without the RMA # will be refused. Call CHAUVET® and request an RMA #
prior to shipping the fixture. Be prepared to provide the model number, serial number and a brief
description of the cause for the return. Be sure to pack fixture properly; any shipping damage
resulting from inadequate packaging is the customer’s responsibility. As a suggestion, proper
UPS packing or double-boxing is always a safe method to use. CHAUVET® reserves the right to
use its own discretion to repair or replace product(s).
