NOTICE!
Possible data transmission errors
For error-free operation make use of dedicated DMX cables and do not
use ordinary microphone cables.
Never connect the DMX input or output to audio devices such as mixers
or amplifiers.
In the following we list a few common problems that may occur during operation.
We give you some suggestions for easy troubleshooting:
Symptom Remedy
The unit does not work, no
light, the fan does not run
Check the mains connection and the main fuse.
No response to the DMX con‐
troller
1. The set DMX address should appear continu‐
ously in the display. If the address flashes in the
display, check the DMX connectors and cables for
correct connection.
2. If the set DMX address is displayed continuously
but there is still no response, check the address
settings and DMX polarity.
3. Try using another DMX controller.
4. Check whether the DMX cables run near or par‐
allel to high-voltage cables that may cause
damage or interference to a DMX interface circuit.
If the procedures recommended above do not succeed, please contact our Service
Center. You can find the contact information at www.thomann.de .
