1. Check the DMX connectors and cables for proper con‐

nection.

2. If the unit is in DMX mode with a DMX controller con‐

nected and turned on, the display shows ‘Dmx In’ . If it

doesn't, no valid DMX signal is received. Check whether

the DMX controller is switched on. Check the DMX con‐

nectors and cables for proper connection.

3. If the display shows ‘Dmx In’ but there is still no

response, check the address settings and the DMX

polarity.

4. Try using another DMX controller.

5. Check whether the DMX cables run near or parallel to

high-voltage cables that may cause damage or interfer‐

ence to a DMX interface circuit.
