Connect fixtures using shielded 2-conductor twisted pair cable with 3-pin XLR male to
female connectors. The shield connection is pin 1, while pin 2 is Data Negative (S-), and
pin 3 is Data positive (S+).

4.2. 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.
