1. if you using a controller with 5 pins DMX out put,you need to use a 5 to 3 pin
adapter-cable.
2. At last unit,the dmx cable has to be terminated with aterninator.Solder a 120 ohm 1/4w
resistor between pin 2(DMX -) and pin 3(DMX+) into a 3 -pin XLR-plug and plu g it in
the DMX-out put of the last unit.
3. Connect the unit together in a ' daisy chain ' soldered join ts or corroded connectors can
easily distort the signal and shout down the system.
4. The DMX output and input connectors are pass -through to maintain the DMX
circuit,when one of the units' power is disconnected.
5. Each lighting unit needs to have an address set
controller.The address number is between 0 -511(usually 0 & 1 are equal to 1).
6. The end of the DMX 512 system should be terminated to reduce signal errors.
7. 3 pin xlr connectors are more popular than 5 pin XLR.
3 pin XLR:Pin 1:GND,Pin2:Negative signal( -),Pin 3:Positive signal(+)
5 pin XLR:Pin1:GND,Pin 2;negative signal( -),Pin 3:Positive signal(+),Pin 4/pin 5 ;Not
used.
5 Troubleshooting
Following are a few common problems that may occur during operation.Here are some
suggestions for easy troubleshooting:
1. The unit does not work,no light and the fan does not work
a. check the connection of power and main fuse.
b. Measure the mains voltage on the main connector.
c. Check the power on Led.
2. Not responding to dmx controller
a. DMX LEDshould be on.If not ,check DMX connectors,cables to see if link properly.
b. If the DMXl LED is on and no response to the channel,check the address settings and
DMX polarity.
c. If you have intermittent DMX signal problems,check the pins on connectors or on PCB
of the uni t or the previous one.
d. Try to use another DMX controller.
