Following are a few common problems that may occur during operation. Here are some 

suggestions for easy troubleshooting:

Check the connection of power and main fuse.

Measure the mains voltage on the main connector.

Check the power on LED. 

B. Not responding to DMX controller 

1.

The 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.

If you have intermittent DMX signal problems, check the pins on connectors or on PCB of the 

unit or the previous one.

Try to use another DMX controller.

Check if the DMX cables run near or run alongside to high voltage cables that may cause 

damage or interference to DMX interface circuit.

slave mode signal.
