3.2 DMX operation
3.2.1 Building a serial chain
Connect the DMX-output of the first unit in the DMX-chain with the DMX-input of the next
fixture. Always connect one output with the input of the next unit until all fixtures are
connected.
The last unit of the DMX chain has to be terminated with a resistor. Connect a 120 Ohm
resistor between Signal “-“ and Signal “+” to DMX-output-socket of the last unit .
3.2.2 LED PAR operates as a DMX master
In the DMX master mode, the LED operates as a DMX controller to the connected units in the
DMX chain.
If the LED PAR is used as a DMX master, it must be the first unit in the DMX chain. Unplug
the DMX input cable of the LED PAR which operates as a DMX master.
3.2.3 LED PAR operates as a DMX slave
In the DMX slave mode the LED PAR operates as a normal DMX receiver. It is controlled by
an external DMX controller.
