6. DMX512 CONNECTIONS
The DMX512 is widely used in intelligent lighting control, with a maximum of 512
channels.
Termination reduces signal errors and avoids signal transmission problems and
interference. It is always advisable to connect a DMX terminal. (Resistance 120 Ohms
1/4W between pin2 (DMX-) and pin3 (DMX+) of the last fixture.)
1. If you are using a controller with a 5-pin DMX output, you need to use a 5 to 3 pin
adapter-cable.
2. 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 branched 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.
3. The DMX output and input connectors are pass-through to maintain the DMX circuit
when one of the units’ power is disconnected.
4. 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.
5. 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).
6. 3-pin XLR connectors are more common than 5-pin XLR ones.

7. TROUBLESHOOTING
You will find below a few common
problems that may occur during
operation.
Here are some suggestions to ease the
troubleshooting:
The fixture does not work, no light
•
Check the connection to power and
the mains fuse.
•
Measure the mains voltage on the
main connector.
Not responding to DMX controller
•
DMX LED should be on. If not, check
DMX connectors and cables to see if the
units are linked correctly.
•
If the DMX LED is on but there is no
response to the channel, check the
address settings and the DMX polarity.
•
If you have intermittent DMX signal
problems, check the pins on the
connectors or on the PCB of the fixture
or the previous one.
•
Try to use another DMX controller.
•
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?
•
You may have a breakage in the DMX
cabling. Check the LEDs indicating
response to the master/ slave mode
signal.
•
Check DMX address.
No response to the sound
•
Make sure the fixture does not
receive any DMX signal
•
Check the microphone to see if it is
sensitive to sound by tapping lightly on
the microphone.
One of the channels is not working well
•
The stepper motor might be damaged
or the cable connected to the PCB is
broken.
•
The motor’s drive IC on the PCB might
be out of order.
8. FIXTURE CLEANING
The cleaning of internal optics must be
carried out periodically to optimize light
output. The frequency of cleaning
depends on the environment in which
the fixture is operated: damp, smoky or
particularly dirty surroundings can
cause a greater accumulation of dirt on
the fixture’s optics.
•
Clean with a 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.
