6.1. 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 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 (+), respective-
ly, pins 2 and 3, which is then plugged into the output socket on last
projector in the chain. The connections are illustrated below.
Complimentary signal cable can transmits signals to 20 unit xtures at most.
Signal amplier is a must to connect more xtures.
6.2. 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.
Following the wiring correspondence between 3-Pin and 5-Pin plug and socket stan-
dards

7. FRONT/REAR PANELS
1. Laser Aperture: The laser effect output aperture. Never look inside the xture
through this aperture while the xture is operating.
2. Remote: Infrared remote receiver.
3. POWER: Main power indicating LED. Red is ON.
4. Sensitivity: Turn the knob to adjust sound activated sensitivity.
