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 DMX channel):
Projector 1: DMX address 1
Projector 2: DMX address 2
Projector 3: DMX address 3
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 will project white light.
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.

The wire size we recommended is 26 AWG or higher.
The external diameter of cable must be included between 4 and 7mm (PG9 cable clamps).
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)
