DMX TERMINATOR
In the Controller mode, at the last fixture in the chain, the DMX output has to be connected with a DMX terminator. This
prevents electrical noise from disturbing and corrupting the DMX control signals.
The DMX terminator is simply an XLR connector with a 120
Ω
(ohm) resistor connected across pins 2 and 3, which is
then plugged into the output socket on the last projector in the chain. The connections are illustrated below.
