To activate an electric motorised screen a 12 Volt output is
provided at the rear of the DigiOptic™ Image Processor.  This
can be connected to a screen interface unit, which can be
supplied by screen manufacturers 
(Fig. 10).
 
Fig. 10
The output is activated (Voltage: 12 Vdc) when the Projector is
switched on and is de-activated (no Voltage output) when the
projector is in stand-by mode.
Some manufacturers offer screen-masking systems to help fra-
me the projected image and improve picture contrast....

most common types of video sources and the corresponding
input connectors to use on the DigiOptic™ Image Processor).

The video or graphic signals that can be connected to this
input can have horizontal scan frequencies (H-sync) of between
15 and 110 kHz and a vertical frequency (V-sync) of between
40 and 100 Hz. Image resolution can vary between 640x480
and 1600x1200 pixels (VGA, SVGA, XGA, SXGA, UXGA).

This input allows you to advantage from  the quality of the digital
images .
If your source is equipped with a DVI-D output, YCrCb or RGB

The HT300 LINK system consists of the Projector and the
DigiOptic™ Image Processor (which is also the system control
centre). The DigiOptic™ Image Processor sends commands
to the Projector and receives operating status information from
the Projector and function commands from the user. The system
can be controlled from either the remote control (via the infrared
sensors on the DigiOptic™ Image Processor and on the
Projector) or the keypad located on the rear of the Projector.
The two units have...

Typically, the picture will appear after 15-20 seconds. Pressing
a key from 1-9 on the remote control selects the corresponding
input; pressing 0 selects the input active at the time the system
was last switched off.
If the system is switched on very soon after it was last switched
off, the lamp may fail to come on because it is too hot. In this
case just wait a few minutes to allow the lamp to cool.

7  REMOTE CONTROL
The remote control transmits commands to the system by
infrared signals.
There are three infrared sensors, one at the front of the Projector,
one at the rear of the Projector and one on the front panel of the
DigiOptic™ Image Processor.
It is possible to control the projector by pointing the remote
control at the screen; the sensor at the front of the projector will
pick up the reflected infrared commands.

The various menus only offer the relevant adjustments in
accordance with the type of input signal displayed (e.g. certain
typical adjustments for video signals, not necessary for graphic
signals, do not appear on the menus, and vice versa).
Some adjustments (e.g. 
BRIGHTNESS and CONTRAST) are
associated with a numerical value that can be varied within the

will be shown in black and white. Increasing the value, try to
find the point at which the colours look natural: suitable
references include skin tones and grass in landscape shots.
TINT
Controls the purity of the colours. Basically determines the
red-green ratio of the picture.
Reducing the value will boost the red contents of the picture,
increasing the value will boost the green tones. For this
adjustment use skin tones or a test pattern...
