Example of connection of the DMX line:
To avoid the risk of faulty operation, follow these indications:
Maximum cable length:
500 m
Max. N° of fixtures connected:
32 units
Cable runs:
Avoid running cables alongside power supply lines.
Termination:
A 120Ohm resistor between Pins 2 and 3 on the last fixture.
2.12
Construction of the DMX termination
The termination avoids the risk of DMX 512 signals being reflected back along the cable when they reaches
the end of the line: under certain conditions and with certain cable lengths, this could cause them to cancel
the original signals.
The termination is prepared by soldering a 120Ohm 1/4 W resistor between pins 2 and 3 of the 5-pin male
XLR connector (see diagram).
