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
