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 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 (+), 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 fixtures at most.
Signal amplifier is a must to connect more fixtures.
6.2. 3-Pin vs 5-Pin DMX cables
DMX connection protocols used by controllers and fixtures 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
fixture, 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
5-Pins XLR (plug)
Pin 1: GND (Screen)
Pin 2: Signal (-)
Pin 3: Signal (+)
Pin 4: N/C
Pin 5: N/C
3-Pins XLR (socket)
Pin 1: GND (Screen)
Pin 2: Signal (-)
Pin 3: Signal (+)
5-Pins XLR (socket)
Pin 1: GND (Screen)
Pin 2: Signal (-)
Pin 3: Signal (+)
Pin 4: N/C
Pin 5: N/C
3-Pins XLR (plug)
Pin 1: GND (Screen)
Pin 2: Signal (-)
Pin 3: Signal (+)
7. FRONT/REAR PANELS
1. Laser Aperture: The laser effect output aperture. Never look inside the fixture
through this aperture while the fixture 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.
