OPERATING INSTRUCTIONS
Operating Modes
The Omega™ 250C DMX-250C can be operated in three ways.



A stand-alone mode will listen to sound and run through its diverse range of built in programs.
Master/Slave mode will allow the command of up to as many units you want in a synchronized light
show to the sound.
DMX control mode will provide the greatest flexibility and creativity. Each fixture trait can be controlled
individually using any universal DMX-512 controller.
Stand Alone
The Stand Alone mode is activated automatically when the fixture is absent of DMX signal or a
controller is not connected. The Omega™ 250C will run through its built in programs as it listens to
the sound.
Master/Slave
The Master/Slave mode will allow you to link up to as many units you want in a daisy chain fashion. In
this mode, the first unit in the daisy chain will automatically command all other units following. The
programs are constructed based on the control of four units. Connecting the Omega™ 250Cs for
(Master/Slave) operation does not require any menu or setting selections. Simply connect each
Omega™ 250C in a daisy like fashion using qualified 3 pin DMX cables as described below.
MAST ER/ SL AVE SET T I NG S
1)
Connect the (male) 3 pin connector side of the DMX cable to the output (female) 3 pin connector
of the first fixture.
2)
Connect the end of the cable coming from the first fixture which will have a (female) 3 pin
connector to the input connector of the next fixture consisting of a (male) 3 pin connector. Then,
proceed to connect from the output as stated above to the input of the following fixture and so on
as illustrated below in figure 5.
The built in programs were created using a set of 4 fixtures. When connecting fixtures together,
leaving all dipswitches in the off position, will enable the auto-location function. The auto-location

DMX Mode
Operating in a DMX Control mode environment gives the user the greatest flexibility when it comes to
customizing or creating a show. You can tailor your programming to suit a specific event. Whether it
is a wedding where a spot light may be required or a lead singer requiring a color solo, the
opportunities are end less. In this mode you will be able to control each individual trait of the fixture
independently.
SET T I NG T HE ST ART I NG ADDRESS
This DMX mode enables the use of a universal DMX controller device. Each fixture requires a "start
address" from 1 to 511. 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 occupies or uses 6 channels
of DMX 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 notate
the start address selected for future reference.
If this is your first time addressing a fixture using the DMX-512 control protocol then I suggest jumping
to the Appendix Section and read the heading “DMX Primer”. It contains very useful information that
will help you understand its use.
Set the start address using the group of DIP switches located usually on bottom of the fixture. Each
dip switch has an associated value. Adding the value of each switch in the ON position will provide

the start address. Determining which switches to toggle ON given a specific start address can be
accomplished in the following manner. By subtracting the largest switch value possible from the
selected start address which does not cause a negative number.

APPENDIX
DMX Primer
There are 512 channels in a DMX-512 connection. Channels may be assigned in any manner. A
fixture capable of receiving DMX 512 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 be slaved together and all respond exactly the same.
DMX fixtures are designed to receive data through a serial 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 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+). CHAUVET
carries 3-pin XLR DMX compliant cables, DMX-10 (33’), DMX-4.5 (15’) and DMX-1.5 (5’)

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 and internal components. Clean all glass when the fixture is cold 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. Do not to touch the lamp glass when cleaning fixture. Oil
and dirt can cause damage and premature aging of the lamp. In the event that the lamp is touched or
becomes dirty, clean the lamps with an alcohol wipe.
The cleaning of internal and 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 surrounding can cause greater accumulation of dirt on the unit’s
optics. Clean with soft cloth using normal glass cleaning fluid. - Always dry the parts carefully. - Clean
the external optics at least every 20 days. Clean the internal optics at least every 30/60 days.
Returns Procedure
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 Merchandise Authorization Number (RA #). Products
returned without an RA # will be refused. Call CHAUVET and request RA # 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 properly pack fixture, any shipping damage resulting from inadequate
packaging is the customer’s responsibility. CHAUVET reserves the right to use its own discretion to
repair or replace product(s). As a suggestion, proper UPS packing or double-boxing is always a safe
method to use.
Claims
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.
