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 between 0-511 (usually 0 & 1 are equal to
1).
6. 3 pin XLR connectors are more popular than 5 pin XLR.
3 pin XLR: Pin1: GND, Pin2: Negative signal (-), Pin3: Positive signal (+)
5 pin XLR: Pin1: GND, Pin2: Negative signal (-), Pin3: Positive signal (+)
Pin4/5: Not Used.
8. Troubleshooting
Following are a few common problems that may occur during operation. Here are some
suggestions for easy troubleshooting:
A. The fixture does not work, no light
1. Check the connection of power and main fuse.
2. Measure the mains voltage on the main connector.
B. Not responding to DMX controller
1. DMX LED should be on. If not, check DMX connectors, cables to see if link properly.
2. If the DMX LED is on and no response to the channel, check the address settings and
DMX polarity.
3. If you have intermittent DMX signal problems, check the pins on connectors or on PCB
of the fixture or the previous one.
4. Try to use another DMX controller.
5. Check if the DMX cables run near or run alongside to high voltage cables that may
cause damage or interference to DMX interface circuit.
C. Some fixtures don’t respond to the easy controller
1. You may have a break in the DMX cabling. Check the LED for the response of the
master/ slave mode signal.
2. Wrong DMX address in the fixture. Set the proper address.
D. No response to the sound
1. Make sure the fixture does not receive DMX signal.
2. Check microphone to see if it is good by tapping the microphone.
9. Fixture Cleaning
The cleaning of internal 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 fixture’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.
