4. OPERATING INSTRUCTIONS 
Configuring the Starting Address 
The Obsession™ LED fixture uses three DMX channels. The highest channel that the fixture may 
be set to in order to function properly is 510. Any address higher than this will prevent access to 
all of the channels. 
If this is your first time using DMX, we recommend reading the “DMX Primer” section in the  
“Appendix”. 
This is the operating mode which will allow for control with an external DMX controller. You must 
set the starting address for this mode. If this is your first time using DMX, then it is recommended 
that you refer to the “DMX Primer” section in the “Appendix” of this manual. 
  Mode    DIP switches 
DMX    1~9 = set to the DMX starting address  
    10 = On 
Master/Slave Mode (Sound-Active, Auto Mode) 
This mode allows a single unit to auto change in Standalone Mode. 
Turn switch to the Slave position on the slave units, and they will react the same as the Master. 
The Master must be set to standalone mode.

5. Appendix  10  12/20/2010 2:38 PM 

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 
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. 
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 
Maximum capacitance between conductors:  30 pF/ft 
Maximum capacitance between conductor and shield:  55 pF/ft 
Maximum resistance:  20 ohms/1000 ft 
Nominal impedance:  100 ~ 140 ohms 
5. Appendix  11  12/20/2010 2:38 PM 

Cabling must have a male XLR connector on one end and a female XLR 
connector on the other end. 
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. 
120 ohm ¼ W resistor 
between pin 2 (DMX -) and 
pin 3 (DMX +) on the 
output of the last fixture 
To avoid signal transmission problems 
and interference, it is always advisable to 
connect a DMX signal terminator.

3-Pin to 5-Pin Conversion Chart 
If you use a controller with a 5-pin DMX output connector, you will need to use a 5-pin to 
3-pin adapter. The chart below details a proper cable conversion: 
3-PIN TO 5-PIN CONVERSION CHART 
Setting up a DMX Daisy Chain 
1. Connect the (male) 3-pin connector side of 
the DMX cable to the output (female) 3-pin 
connector of the controller.  
2. Connect the end of the cable coming from the 
controller which will have a (female)  3-pin 
connector to the input connector of the next 
fixture consisting of a (male) 3-pin connector. 
3. Then, proceed to connect from the output as 
stated above to the input of the following 
fixture and so on.

illustration of the 
DMX input/output 
panel of a lighting 
fixture. 
5. Appendix  13  12/20/2010 2:38 PM 

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. 
The cleaning of external optical lenses and/or mirrors must be carried out periodically to optimize 
light output. Cleaning frequency depends on the environment in which the fixture operates. 
Damp, smoky or particularly dirty surroundings can cause greater accumulation of dirt on the 
unit’s optics. Clean with soft cloth using normal glass cleaning fluid. Clean the external optics at 
least every 20 days. Clean the fixture at least every 30/60 days. 
Always dry the parts carefully after cleaning them. 
Never spin a fan using compressed air. 
Returned merchandise must be sent prepaid and in the original packing; call tags will not be 
issued. Package must be clearly labeled with a Return Merchandize Authorization Number (RMA 
#). 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). 
If you are given an RMA #, please include the following information on a piece of paper 
inside the box: 
1)  Your name 
2)  Your address 
3)  Your phone number 
4)  The RMA # 
5)  A brief description of the symptoms 
Damage incurred in shipping is the responsibility of the shipper; therefore, the damage must be 
reported to the carrier upon receipt of merchandise. It is the customer's responsibility to notify 
and submit claims with the shipper in the event that a fixture is damaged due to shipping. Any 
other claim for items such as missing component/part, damage not related to shipping, and 
concealed damage, must be made within seven (7) days of receiving merchandise.
