Inadequate or damaged cables, soldered joints or corroded connectors can easily distort the signal
and shut down the system.
4. The DMX output and input connectors are pass-through to maintain the DMX circuit, when one of the
units' power is disconnected.
5. Each lighting unit 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. The end of the DMX 512 system should be terminated to reduce signal errors.
7. 3 pin XLR connectors are more popular than 5 pin XLR.
3 pin XLR: Pin 1: GND, Pin 2: Negative signal (-), Pin 3: Positive signal (+)
5 pin XLR: Pin 1: GND, Pin 2: Negative signal (-), Pin 3: Positive signal (+), Pin 4/Pin 5: Not used.
5. Troubleshooting
Following are a few common problems that may occur during operation. Here are some
suggestions for easy troubleshooting:
A. The unit does not work, no light and the fan does not work
1. Check the connection of power and main fuse.
2. Measure the mains voltage on the main connector.
3. Check the power on LED.
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
polarity.
3. If you have intermittent DMX signal problems, check the pins on connectors or on PCB of the unit 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 units 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 unit. Set the proper address.
D. No response to the sound
1. Make sure the unit does not receive DMX signal.
2. Check microphone to see if it is good by tapping the microphone
E. One of the channels is not working well
1. The stepper motor might be damaged or the cable connected to the PCB is broken.
2. The motor's drive IC on the PCB might be out of condition
