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. Solder
a 120 Ohm 1/4 W resistor between Signal „―“ and Signal „+“ into a XLR
plug and plug it into the 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.
