Termination reduces signal errors and to avoid signal transmission problems and interference. It is always
advisable to connect a DMX terminal. (resistance 120ohm 1/4W ) between pin2 (DNX-) and pin3 (DMX+)
of the last fixture.
1.
Connect the fixture together in a “daisy chain” by XLR plug cable from the output
of the fixture to the input of the next fixture. The cable cannot be branched or
split to a 2Y” cable. Inadequate or damaged cables, soldered joints or corroded
connectors can easily distort the signal and shut down the system.
2.
The DMX output and input connectors are pass-through to maintain the DMX
circuit when no power is connected to the fixture.
3.
At last fixture, the DMX cable has to be terminated with a terminator to reduce
signal errors. 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 fixture.
4.
Each lighting fixture needs to have an address set to receive the data sent by the
controller. The address number is between 0-511 (usually 0 & 1 are equal to 1).
5.
3 pin XLR: Pin 1: GND, Pin 2: Negative signal (-), Pin 3: Positive signal (+).
Notice:
A. If no any touch the button within 20 seconds, the LED display will be close, if touch
any button at this time, the LED display will be recover the original status. All the button
will be recover the function,
B. This fixture have the excess temperature self defective function. When the brightness
is obvious reduce, please check if the fan work in normal, after clear the trouble clear,
please power supply, the light will be release defend, and work in normal.
C. Turn on the fixture, it will show the Version No. like V2.0. It will keeps two seconds,
then under the working mode which the user set up.

TROUBLESHOOTING
Following are a few common problems that may occur during operating. Here are some
suggestions for easy troubleshooting:
•
The fixture does not work, no light & the fan does not work
:
1.
Check the connection of power and main fuse.
2.
Measure the mains voltage on the main connector.
•
Not responding to DMX controller
:
1.
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.
3.
If you have intermittent DMX SIGNAL problems, check the pins on connectors or
on PCB of the fixture or the previous one.
4.
Try to use another DMX controller
5.
Check if the DMX cables run near or run alongside to high voltage cables that
may cause damage or interference to DMX interface sircuit.
