Example of connection
Example 1: The DMX signal is generated by a DMX controller, the signal cable goes in and out from each projector up to the
last one.
The projectors will execute the same scenes if the DMX addresses are the same (factory set is 1) or they can be driven one by
one if the DMX addresses are different from each other. (each projector uses 1 or 3 DMX channels):
Projector 1: DMX address 1 Projector 2: DMX address 4 Projector 3: DMX address 7
Example 2: The DMX signal is generated by a projector on stand alone mode (MASTER).
The projector MASTER will automatically execute scenes and it will drive the projector SLAVE of the same model.
In the two examples the projectors can be fed from different power sources, it is not necessary to switch on the projectors at the
same time.
If the DMX controller or the MASTER projector is not switched on, the projectors are on black-out (version with
dimmer/black-out) or they will project white light (version without dimmer/black-out).
DMX signal cable
Use only shielded and twisted cables with EIA485 (RS485) standards. The cable must be low capacity and an impedance
between 82 and 120 ohm.
It is preferable not to use audio cables.
We advise you to read the example of the following tables as a reference to use to correct cables.
Cables with 1 pair of wires Cables with 2 pairs of wires
Type Cod. AWG Impedance (ohm) Type Cod. AWG Impedance (ohm)
BELDEN 1162A 20 100 BELDEN 8102 24 100
BELDEN 8227 20 100 BELDEN 8162 24 100
BELDEN 89207 20 100 BELDEN 89696 22 100
ALPHA 9109 20 100 PROPLEX PC224P 22 110
ALPHA 9817 20 100 PROPLEX PC224T 22 110
ALPHA 9818 20 100
The wire size we recommended is 26 AWG or higher.
It is preferable:
- not to insert over 32 projectors each DMX chain
- not to use more than 150m of signal cable (with low quality cable)
- not to use more than 300m of signal cable (with good quality cable)
