6. DMX 512 Connection
The DMX 512 is widely used in intelligent lightings and with a maximum of 512 channels.
1.
If you using a controller with 5 pins DMX output, you need to use a 5 to 3 pin adapter-cable.
2.
At last unit, the DMX cable has to be terminated with a terminator. 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.
3.
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 cannot be branched or split to a ‘Y’ cable. DMX512 is a very
high-speed signal. Inadequate or damaged cables, solder joints or corroded connectors can
easily distort the signal and shut down the system.
4.
Each lighting unit 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).
7. Troubleshooting
Following are a few common problems that may occur during operation. Here are some
suggestions for easy troubleshooting:
The fixture does not work, no light
o
Check the connection of power and main fuse.
o
Measure the mains voltage on the main connector.
Not responding to DMX controller
o
DMX LED should be on. If not, check DMX connectors, cables to see if link
properly.
o
If the DMX LED is on and no response to the channel, check the address
settings and DMX polarity.
