1.
The last units DMX cable has to be terminated with a 120 ohm 1/4W resistor between pin
2(DMX-‐) and pin 3(DMX+) of a 3-‐pin XLR-‐plug and plug it in the DMX-‐output of the last unit.
2.
Connect the unit together in a `daisy chain` by XLR plug from the output of the unit to the
input of the next unit. The cable can not branched or split to a `Y` cable.
3.
The DMX output and input connectors are pass-‐through type to maintain the DMX circuit,
when one of the units’ power is disconnected.
4.
Each fixture needs to have an address set 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.
3 pin XLR: Pin 1: GND, Pin 2: Negative signal (-‐), Pin 3: Positive signal (+)
6. 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 output
1.
Check the power connection and main fuse.
B.
Not responding to DMX controller
1.
DMX LED should be on. If not, check DMX cables to see if linked correctly.
2.
If the DMX LED is on and no response to the controller, check the address settings and DMX
polarity.
3.
Try another DMX controller.
