The DMX512 is widely used in intelligent
lighting control, with a maximum of 512
channels.
ì
If you are using a controller with a 5-pin
DMX output, you need to use a 5 to 3 pin
adapter-cable.
ì
Connect the fixtures together in a
“daisy chain” via XLR plug cables, from
the output of a fixture to the input of the
next fixture. The cable cannot be bran-
ched or split to a “Y” cable. Inadequate
or damaged cables, soldered joints or
corroded connectors can easily distort
the signal and shut down the system.
ì
The DMX output and input connectors
are pass-through to maintain the DMX
circuit when one of the units’ power is
disconnected.
ì
At the last fixture, the DMX cable has
to be terminated with a terminator to
reduce signal errors. Solder a 120-ohm
1/4W resistor between pin 2 (DMX-) and
pin 3 (DMX+) into a 3-pin XLR-plug and
plug it in the DMX-output of the last
fixture.
ì
Each lighting fixture needs to have an
address set to receive the data sent by
the controller. The address number is
comprised between 0-511 (usually 0 &
1 are equal to 1).
ì
3-pin XLR connectors are more
common than 5-pin XLR ones.
ì
3-pin XLR:
Pin 1: GND,
Pin 2: Negative signal (-),
Pin 3: Positive signal (+)
ì
5-pin XLR:
Pin 1: GND,
Pin 2: Negative signal (-),
Pin 3: Positive signal (+),
Pin 4/5: not used
8. TROUBLESHOOTING
You will find below a few common
problems that may occur during opera-
tion. Here are some suggestions to ease
the troubleshooting:
ì
The fixture does not work, no light
Check the connection to power and the
mains fuse.
ì
Measure the mains voltage on the main
connector.
Not responding to DMX controller
ì
DMX LED should be on. If not, check
DMX connectors and cables to see if the
units are linked correctly.
ì
If the DMX LED is on but there is no
response to the channel, check the
address settings and the DMX polarity.
ì
If you have intermittent DMX signal
problems, check the pins on the
connectors or on the PCB of the fixture
or the previous one.
ì
Try to use another DMX controller.
ì
Check if the DMX cables run near or
alongside high voltage cables that may
cause damage or interference to the
DMX interface circuit.
The device can’t slave to another one ?
ì
You may have a breakage in the DMX
cabling.
ì
Check the LEDs indicating response to
the master/ slave mode signal.
No response to the sound
ì
Make sure the fixture does not receive
any DMX signal.
ì
Check the microphone to see if it is
sensitive to sound by tapping lightly on
the microphone.
9. FIXTURE CLEANING
The cleaning of internal must be carried
out periodically to optimize light output.
Cleaning frequency depends on the envi-
ronment in which the fixture operates:
damp, smoky or par ticularly dir ty
surrounding can cause greater accumu-
lation of dirt on the fixture’s optics.
ì
Clean with soft cloth using normal glass
cleaning fluid.
ì
Always dry the parts carefully.
ì
Clean the external optics at least every
20 days. Clean the internal optics at
least every 30/60 days.

Termination reduces signal errors and avoids signal
transmission problems and interference. It is always
advisable to connect a DMX terminal.
