11- DMX SIGNAL CONNECTION
The unit operates using the digital DMX 512 (1990) signal.
Connection between the mixer and the projector or between projectors must be carried
out using a two pair screened ø 0.5 mm cable and a XLR 5 or 3 pins connector.
Ensure that the conductors do not touch each other.
Do not connect the cable ground to the XLR chassy.
The plug housing must be isolated. Connect the mixer signal to the DMX IN projector
plug and connect it to the next projector by connecting the DMX OUT plug on the first
projector to the DMX IN plug of the second one.
This way, all the projectors are cascade connected.
NB. If the display showing the DMX address flashes, then one of the following errors
has occurred:
- DMX signal not present
- DMX address not valid
- DMX reception problem
For Installations where long distance DMX cable connections are needed, we suggest
to use a DMX terminator.
The DMX terminator is a male XLR 3-5 pins connector with a 120 ohm resistor
between pin 2 and 3.
The DMX terminator must be plugged into the last unit (DMX out panel connector) of
the DMX line.
PLACE A 120 OHM RESISTOR BETWEEN PIN 2
AND 3 OF A MALE XRL CONNECTOR AND PLUG IT
INTO THE DMX OUT PANEL CONNECTOR OF THE
LAST UNIT CONNECTED TO THE DMX LINE
