4.4 DMX512 CONNECTION
1.
In the last unit, the DMX has to be terminated with a termination plug.
Solder a 120 ohm 1/4W resistor between pin 2(DMX-) and pin
3(DMX+) into a 3-pin XLR-plug and plug it in the DMX-output of the
last unit.
2.
Connect the units together in a `daisy chain` with an XLR plug from
the output of the unit to the input of the next unit. The cable can not
be branched or split to a `Y` cable.
3.
The DMX output and input connectors are a pass-through type to
maintain the DMX circuit when one of the units’ power is
disconnected.
4.
Each lighting unit needs to have an address setup to receive the data
sent by the controller. The address number is between 0-512 (usually
0 & 1 are equal to 1).
5.
The end of the DMX 512 system should be terminated to reduce signal
errors.

5.Troubleshooting
Following are a few common problems that may occur during
operation and some suggestions for easy troubleshooting:
A. The unit does not work, no light and the fan does not work
1.
Check the connection of the power and the main fuse.
B. Not responding to DMX controller
1.
Check DMX cables to see if linked correctly.
2.
If the DMX address is showing but no response to the controller,
check the address settings and DMX polarity.
3.
Try another DMX controller.
C. No response to the sound
1.
Make sure the unit is not receiving a DMX signal.
2.
Check the microphone to see if it is good by tapping it. The
microphone is located on the bottom plate of the unit.
6. Fixture Cleaning
The cleaning of external optical lenses must be carried out periodically to
optimize light output. Cleaning frequency depends on the environment in
which the fixture operates: damp, smoky or particularly dirty surrounding
can cause a greater accumulation of dirt on the unit’s optics.
Clean with a soft cloth using normal glass cleaning fluid or mild soapy
water.
Always dry the parts carefully.
Clean the external optics at least every 20 days.
