Connect xtures 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+).

CAUTION: Wires must not come into contact with each other; otherwise the
xtures will not work at all, or will not work properly.
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 xture 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 (+), respec-
tively, pins 2 and 3, which is then plugged into the output socket on
last projector in the chain. The connections are illustrated below.
4.3. 3-Pin vs 5-Pin DMX cables
DMX connection protocols used by controllers and xtures manufacturers are not stan-
dardized around the world. However, two are the most common standards: 5-Pin XLR
and 3-Pin XLR system. If you wish to connect SCENESPLIT 8 RACK to a 5-Pin XLR input
xture, you need to use an adapter-cable or make it by yourself.
