TERMINATION OF THE DMX LINE

DMX communications bus
The DMX signal can be affected by electrical noise from other signals. It is recommended to install the DMX bus away from electric cables and
other interferences.
The maximum length of the DMX bus is around 100 m., although it varies depending on the conditions of each installation. In adverse
conditions, repeaters (splitters) (code 41645) should be installed in longer lengths or line branches.
The DMX signal is transmitted from equipment to equipment through a "daisy chain" type connection, where the equipment is connected in a
chain. The DMX cable with the original signal, leaves the DMX controller and is sent to the first equipment of the DMX link. From the first
equipment, the signal goes to the next one and so on. The DMX line is terminated in the last equipment (see next section). Different
equipment can be connected at any point of the line whatever the assigned address.
It is not possible to connect more than one DMX controller in the same DMX bus.
The cable used should be suitable for this type of signal: shielded, twisted pair with a nominal impedance of 120 ohms (80 - 150) and low
capacitance, with a minimum thickness equivalent to 24 AWG.
CONNECTING THE CABLES
Ensure that the projector is NOT receiving
voltage before performing any operation !!
To access inside, unscrew the 4 screws
and open the cover.
Connect the
projectors to the side strips. A maximum
of 4 projectors can be connected per DMX
Feeder.
It is recommended to use
packing gland to insert and seal the input
of cables.
The
DMX
input
cable,
necessary, the output cable, should be
connected to its own strip (DMX IN – DMX
OUT). Connect the DATA cable – to strip
–, the DATA cable + to strip + and the
earth cable to strip
.
Connect the coloured cables, R – Brown;
G – Black; B – Blue and COM – Green-
yellow, of each projector, in accordance
