Dmx 512 Connection - ACME iColorLed 18TC User Manual

6. DMX 512 Connection
The DMX512 is widely used in intelligent lighting control, with a maximum of 512 channels.
1. Connect the fixture together in a "daisy chain" with the 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, bad solder joints or corroded connectors can easily distort the
signal and shut down the system
2. The DMX output and input connectors 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: 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.
