3. Installation
The unit should be mounted via its screw holes on the bracket. Always ensure that the
unit is firmly fixed to avoid vibration and slipping while operating. Always ensure that the
structure to which you are attaching the unit is secure and is able to support a weight of 10
times of the unit’s weight. Also always use a safety cable that can hold 12 times of the weight
of the unit when installing the fixture.
The equipment must be fixed by professionals. And it must be fixed at a place where is out
of the touch of people and has no one pass by or under it.
3.1 Fixture Jointing
Firstly, plug L type Hexagon wrench into the hole back of the fixture to fasten and locate two
fixtures so that movement won’t happen and jointing become more conveniently, please see
figure 1 showed below:

5. How To Control The Unit
You can operate the unit in two ways:
1. By master/slave built-in preprogram function
2. By DMX controller
No need to turn the unit off when you change the DMX address, as new DMX address setting
will be affected at once. Each time you turn the unit on, it will show “ ” on the display.
After that the unit will be ready to receive DMX signal or run the built in programs.
5.1 Master/Slave Built In Preprogrammed Function
By linking the units in master/slave connection, the first unit will control the other units to
give an automatic, sound activated, synchronized light show. This function is good when you
want an instant show. You have to set the first unit in master mode and select (random
show), (show 1) or …or (show 8). Its DMX input jack will have nothing
plugged into it, and Its master LED will be constantly on and sound LED will flash to the
music.
5.2 DMX Controller
Using universal DMX controller to control the units, you have to set DMX address from 1 to

11B
512 channel so that the units can receive DMX signal.
Press the MENU button up to when the is showing on the display. Pressing the ENTER
button and the display will blink. Use the DOWN and UP button to change the DMX512
address. Once the address has been selected, press and hold the ENTER button until the
display stops blinking or storing automatically 8 seconds later. To go back to the functions
without any change press the MENU button again.
If you use please refer to the following diagram to address your DMX512 channel for the first
4 /2 units.

6. DMX512 Connections
mode connection：
mode connection:

16B
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 “Y”
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 one of the units’ power is disconnected.
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 connectors are more popular than 5 pins XLR.
3 pin XLR: Pin 1: GND, Pin 2: Negative signal (-), Pin 3: Positive signal (+)
5 pin XLR: Pin 1: GND, Pin 2: Negative signal (-), Pin 3: Positive signal (+),
Pin4/5: not used
7. Troubleshooting
Following are a few common problems that may occur during operation. Here are some
suggestions for easy troubleshooting:
A. The fixture does not work, no light
1. Check the connection of power and main fuse.
2. Measure the mains voltage on the main connector.
B. 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

17B
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 circuit.
C. One of the channels is not working well
1. The stepper motor might be damaged or the cable connected to the PCB is broken.
2. The motor’s drive IC on the PCB might be out of condition.
8. Fixture Cleaning
The cleaning of internal 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 greater accumulation of dirt on the fixture’s optics.
yClean with soft cloth using normal glass cleaning fluid.
yAlways dry the parts carefully.
yClean the external optics at least every 20 days. Clean the internal optics at least every
30/60 days.
