Remedy
Check the mains connection and the main fuse.
1. The green LED should flash during data transmission.
If it doesn't, check the DMX connectors and cables for
proper connection.
2. If the green LED flashes and there is no response,
check the address settings and DMX polarity.
3. Try using another DMX controller.
4. 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.
