6. DMX512 Connections
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.
