5.1. DMX Terminator
DMX is a resilient communication protocol, however errors still occasionally occur.
In order to prevent electrical noise from disturbing and corrupting the DMX control
signals, a good habit is to connect DMX output of last fixture in the chain to a DMX
terminator, especially over long signal cable runs.
The DMX terminator is simply an XLR connector with a 120Ω (ohm), 1/4 Watt resistor
connected across Signal (-) and Signal (+), respectively, pins 2 and 3, which is then
plugged into the output socket on last projector in the chain. The connections are
illustrated below.

DMX Terminator
Complimentary signal cable can transmits signals to 20 unit fixtures at most.
Signal amplifier is a must to connect more fixtures.
