RS232 INTERFACE CONNECTOR
The projector can be controlled from a PC: simply hookup
the interface connector to a PC’s RS232 serial cable or to a
PC's USB 1.1 cable.
Do not place objects between the remote control and the
receiver on the projector, as this can prevent the remote from
working.

12Volt
120 mA
The projector is equipped with two outputs (Voltage: 12 Vdc)
for motorised projection screen and screen masking systems,
used for masking off the projection area to match the projected
image aspect ratio (Fig. 17).
The +12V output is activated when the projector is switched
on (blue LED on) and is de-activated when the projector is in
standby mode (red LED on). The output can be set with the
“Screen control” adjustment in the “Aspect” menu. This output
allows reduction in the area of a 16:9 screen, into a 4:3 format,
by activating a horizontal screen masking system.

8 REMOTE CONTROL
The remote control requires four 1.5 V batteries, size AAA.
Insert the batteries, taking care to match the polarity, as indi-
cated in the battery compartment in the handset (Fig. 23).
Change the batteries in the remote control if experiencing
difficulty in sending commands to the projector.
Remove batteries from the remote control if it is not to be used
for a long period of time. The batteries are prone to leak and
corrode the remote control’s circuits.
The remote control sends commands to the projector via
infrared signals.
The projector is equipped with an infrared sensor on its front
panel and can therefore be controlled by pointing the remote
control towards the projection screen; the IR beam reflects off
the screen towards the projector (Fig. 19).
There is another infrared sensor in the rear of projector.
