4. OPERATING INSTRUCTIONS

Configuring the Starting Address

DMX Operation

Each fixture requires a starting address from 1~512. A fixture requiring one or more channels for
control begins to read the data on the channel indicated by the starting address. For example, a
fixture that uses seven DMX channels and is addressed to start on DMX channel 100, will read data
from channels: 100, 101, 102, 103, 104, 105 and 106. Choose the starting addresses for each fixture
so that the channels used do not overlap. In addition, you should note the starting address selected
for future reference.

The LEDrain™ 38C fixture uses seven or three DMX 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.

5. APPENDIX

DMX Primer

There are 512 channels in a DMX connection. Channels may be assigned in any manner. 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 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+).

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 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.

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.

To avoid signal transmission problems
and interference, it is always advisable to
connect a DMX signal terminator.

DMX connector configuration

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:

Cable Connectors

Cabling must have a male XLR connector on one end and a female XLR connector on the other end.

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

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.

Fixture Linking

You will need a serial data link 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 serial data link determines the number of fixtures
the data link can support.

Fixtures on a serial data link must be daisy chained in one single line. To comply with the EIA­485 standard, no more than 32 fixtures should be connected on one data link. Connecting
more than 32 fixtures on one serial data link without the use of a DMX optically-isolated
splitter may result in deterioration of the digital DMX signal.

Maximum recommended serial data link distance: 500 m (1640 ft)
Maximum recommended number of fixtures on a serial data link: 32

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

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.
