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.  These
systems can be connected to output, at the rear of the
DigiOptic™ Image Processor 
(Fig. 11).
 
Fig. 11
PFor rear projection the screen must be translucent.
For front projection, we recommend the use of screens with
low gain specifications (i.e. 1.3 to 2).  The use of high gain
screens should be avoided due to their limited viewing angle,
which is undesirable for a large audience.
Preferably, use a screen with black, non-reflecting borders,
which will perfectly frame the projected image.
Avoid light shining directly on the screen during projection as
this will reduce contrast and black level detail on the projected
image.  For the true cinema experience best results are
achieved with little or no ambient light.
Furniture and other objects with reflecting surfaces, as well as
light coloured walls should be avoided, as they are likely to
interfere with the screen’s characteristics.
CONNECTING THE VIDEO SOURCES
Connect the cables from the video sources, the serial cable
from the external control unit and the optical fibre cables for
connection to the Projector, to the rear panel of the DigiOptic™
Image Processor.
To obtain the best performance from the HT300 LINK system,
connect the various signal sources using good quality cables
designed for video applications (rated impedance 75 
).
Ensure that:
•the cables are routed in such a way that they do not present
an obstruction to people moving around the room;
•the connectors are inserted carefully to avoid damaging the
pins;
•the cables are not twisted or crushed;
•when disconnecting the cables the connectors are not
violently pulled out of the sockets on the various units.
Video sources (television receivers, VCRs, DVD players, etc.)
often feature several outputs. To obtain the best performance
from your system, carefully choose which output to use.
Generally, the type of signal offering the best picture quality is
DVI-D, followed by RGB, Components, S-Video and Composite
Video, in that order.
However, the  HT300 LINK system is equipped with an excellent
Video Decoder and Deinterlacer and therefore even inferior
quality signals will produce high quality results. 
						

							10
Table 1 shows the types of signals usually available for the
most common types of video sources and the corresponding
input connectors to use on the DigiOptic™ Image Processor).

VIDEO   
These inputs should be connected to a Composite Video signal
(CVBS) by means of a cable with an RCA connector.
The connector on the source is usually yellow and is frequently
labelled VIDEO.
Although other types of signals are preferable (since they allow
better picture quality), this is still the most common type of
output, and nearly all television receivers, video-recorders, DVD
players, video cameras, etc., are equipped with CVBS outputs.
S-VIDEO   
These inputs should be connected to an S-Video signal by
means of a cable with a 4-pin mini-DIN type connector.
The corresponding output on the source can be identified by
the wording S-VIDEO or Y/C.
Almost as widespread as Composite Video, S-VIDEO is
preferable because it offers a clearer and sharper picture.
COMPONENT / RGBS     
These inputs are composed of three sets of 5 RCA connectors
(5,6,7) and a set of 5 BNC connectors (8).
Each set of connectors is suitable for RGB and Component
signals.
RGB signals can have the following synchronisations:
composite sync on the green signal (RGsB), H+V Composite
Sync, or separate H/V Sync.Connect the R, G, B outputs of the source to the respective R,
G, B inputs of the DigiOptic™ Image Processor (paying attention
not to invert the positions) and any synchronisation signals to
the HV input or the H and V inputs. When connecting the three
sets of RCA connectors use the colours as a guide: connector
R is red, G is green, B is blue, H/HV is white and V is black.
By using a suitable SCART to RCA (or BNC) connector adapter
cable, an RGB video signal from a source equipped with an
SCART connector can be connected to this input.
Component signals are connected to inputs Y, Cr and Cb, taking
care to observe the correspondence with the outputs on the
source.
Since the latter can be labelled in various ways, refer to 
Table 1
to establish the correspondence between the various signals.
The connector colours can also be of help, as shown in the
table.
Input 5 is dedicated for RGB and YCrCb signals up to 32 KHz
only. In fact, in order to guarantee a high image quality, even
with not so accurate sources, the input signal is elaborated by
specific circuit boards in the  DigiOptic™ Image Processor.
The video signal suitable for inputs 6-7-8 can have a scan
frequency of 15KHz (standard video resolution) or 32KHz or
more (progressive scan video, high definition video).
Some sources provide the facility to choose between a
progressive signal or an interlaced signal. Although in general
a progressive signal is higher quality than an interlaced signal,
it is often preferable to perform the deinterlacing operation on
the HT300 LINK system rather than on the source because the
HT300 LINK system is equipped with Faroudja’s sophisticated
directional correlation deinterlacing technology (DCDi™).
Progressive signals usually provide better quality than interlaced
signals, but if the source features both progressive and
deinterlaced signal outputs it is good practice to compare the
quality of the pictures reproduced by the HT300 LINK system
in the two cases: deinterlacing performed by the HT300 LINK
system (thanks to Faroudja DCDi™ technology) is often more
effective than that performed at the source (typically a DVD
player).
RGB GRAPHICS  
This input should be connected to an RGB-type video or graphic
signal using a cable with a DB15HD type connector.
The signal source device (typically a personal computer or
game console) must be able to provide separate H/V
synchronisation or composite H+V synchronisation or
composite synchronisation on the green signal (RGsB). 
						

							11
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).
DVI-D 
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
connect it to this input to exploit the quality of the HT300 LINK
system.
CONTROL (RS232)
The system can be controlled via a personal computer or home
automation systems by means of the serial port: simply connectthis input via a serial cable from an RS232 serial port. On
request, SIM2 will send you a document containing the serial
port settings and the list of main commands.
DIGITAL INPUT 12
The Digital Input allows to extend the signal quality to audio
signal as well.
Through this input it is possible to connect to source capable
of delivering excellent digital images supported by multi-
channel digital audio and by control data.
The internal data elaboration by the DigiOptic™ Image
Processor divides the video data from audio data.
The audio data is available through a TOSLINK connector for
fiber optic output.

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 separate power supplies however: after
connecting the unit to the electrical mains supply:
1) Set the two power switches to “I”; the DigiOptic™ Image
Processor power switch is located on the external power supply
unit
 (Fig. 13c), while the Projector switch is on the rear panel
(Fig. 13a).
2) Turn on the DigiOptic™ Image Processor  by pressing the
button on the front panel 
(Fig. 13b).
After a few seconds (system initialisation interval), the
DigiOptic™ Image Processor and the Projector assume stand-
by mode.
System status information is provided by two LEDs (green and
blue) on the front panel of the DigiOptic™ Image Processor, a
blue and green LEDS on the rear of the Projector.Significant status signals are given in 
Table 3.

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.
Switching the system off 
(Fig.15):
•  from the remote control (
 key)
•  from the Projector keypad (
 key).
If you wish to power off the system completely, wait at least one
minute in stand-by before setting the mains power switches on
the units to the “O” position or disconnecting the power supply
cables. This is to allow the fans in the Projector unit sufficient
time to cool the lamp.
Fig.15
In case the Projector unit is shut down (for example due to a
shut down of the projector unit by putting the switch in the “O”
position or by accidentally unplugging the power cord cable)
to re-boost the HT300LINK system it is necessary to shut down
the DigiOptic™ Image Processor and repeat the power-on pro-
cedure described in point 1 and 2.
In case the connection  with the fiber optics between the two
unit is interrupted (for example by unplagging one or more
cable), to restore the system, it is necessary to turn off the two
units through the main switches and once the connecectin is
restored, repeat steps 1 and 2 of the power-on procedure.

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. 
(Fig. 16).

remote control performance.
Insert the batteries, taking care to match the polarity, as
indicated in the battery recess of the remote 
(Fig. 17).
Change the batteries in the remote control if experiencing
difficulty in sending commands to the projector.
If the remote control is not to be used for a long period of time
remove the batteries. Replace all batteries at the same time;
do not replace one new battery with a used battery. If the
batteries have leaked, carefully wipe the case clean and replace
with new batteries.

Input 11 is capable of receiving YCrCb or RGB signals coming
from DVI-D sources.
The selection should be made from the drop menu following
the indications described above.
After selecting the source signal (by means of the 
 and 
keys), press MENU+/MENU - to confirm and close the pull-
down menu; the value you have just set will be displayed on
the right of the < symbol.
As with the other inputs, you can now select the input just set
by pressing the  key.
During the short time it takes to find the signal, a box appears
showing the signal requested. As soon as the signal is shown
in the box additional information is displayed concerning the
video standard (for video signals) or resolution (for graphic
signals), and format.
Fom the 
SETUP menu it is possible to choose to visualize or not
this information, for more details check the “
SOURCE
INFORMATION
” in “MENU” section.
INPUTS
The input selection menu (Inputs) is called by pressing 0 on
the remote control and, when no other menu is displayed, using
the 
 and  keys on the keypad. To select an input, scroll the
list with the 
 and  keys until the desired input is highlighted,
then press .
Display of the input selection menu is terminated
by pressing the ESC key, or when the time allowed for displaying
the on-screen menu has lapsed (set in the Set-up Menu).
Input 5 can accept RGB and YCrCb signals with a scan
frequency up to 32Khz.
Inputs 6, 7 and 8 can receive RGB and YCrCb signals, at 15
kHz, 32 kHz or higher. The association between the input and
the type of signal is made from the pull-down menu that appears
on the right of the < symbol after pressing the  key 
(Fig. 18b). All system functions can be activated from the keypad or remote control with the aid of a practical and comprehensive system of
on screen menus.

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
set limits using the keys  / .  For others (e.g. 
VIDEO TYPE) you
can choose among three options presented on the same

These submenus are accessed by pressing the  key, while
exit and return to the upper level occurs by pressing 
MENU+/-.
Press 
ESC on the remote control or keypad to interrupt the
menu display or wait for it to disappear automatically after the
number of seconds set on the 
SETUP page.
PICTURE
This menu features the adjustments related to picture quality.
Adjustments that are not available for a given input do not
appear on the menu. 
Table 4 summarises the adjustments
available for each input. For a complete overview of the on-
screen menus, consult the ‘On screen menu layout’ in the
“Additional Information” section.
BRIGHTNESS
Use this control to adjust the image’s black level without
affecting white areas. Increasing the value will give more detail
in darker parts of the picture. For correct adjustment it may
prove useful to display the signal relative to the grey scale within
which the black level and the level immediately above it must
be separately identifiable. Alternatively use a scene composed
of black objects alongside other dark coloured objects.
CONTRAST
Use this control to adjust the image’s black level without
affecting white areas.
To ensure correct adjustment, it may prove useful to display
the signal relative to the grey scale, within which the white level
and the level immediately below it must be separately
identifiable. Alternatively use a scene composed of well-lit white
objects surrounded by light coloured objects with lower level
lighting.
COLOR
This control (also called Saturation) increases or decreases 
						

							18
the picture colour intensity. When set to zero, colour images
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 image with colour
bars as a reference.
SHARPNESS
Use this adjustment to increase and decrease the level of
picture detail.
When the sharpness value is reduced the image details
appear less pronounced, while increasing the value raises
image definition, making the outline of objects sharper.
Note that an excessively high value may result in a ‘noisy’ picture
and the edges of objects may be unnaturally defined.
SHARPNESS MODE
This allows you to select the type of processing associated
with sharpness adjustment. In the case of a progressive or
interlaced video signal 
VIDEO mode is advisable; with PC graphic
signals use 
GRAPHIC MODE.
FILTER
This allows you to select the mode in which the input signal
is processed. Selecting the most appropriate value for a given
input signal ensures the best horizontal and vertical definition
and makes the picture sharper.
CINEMA MODE
In AUTO the deinterlacer recognises if the video signal source
is a movie film (obtained from a Telecine device with 3:2 or 2:2
pull-down) and applies a deinterlace algorithm optimised for this
type of signal.
If the video signal source is not identified as a film, or if you
select 
NO the deinterlacer applies a Motion compensated
algorithm optimised for video camera signals.
VIDEO TYPE
Activates a filter to improve stability of pictures from video
recorders. To toggle between 
NORMAL, VCR1 mode and VCR2
mode press  on the remote control.
NOISE  REDUCTION
This adjustments allows to choose the filter value for noise
reduction purposes.
As soon as this option is selected on the menu, the image is
divided in two parts.
In the left side the image is not altered by the filter, in the right
part the filter is activated.
This allows you to compare the effect of the filter.
It is possible to deactivated the filter (
NOT ACTIVE), to use the
automatic adjustments (
AUTO) or to manually select (MANUAL)
the value suitable for the image with the 
VALUE adjustment.
In case of using the 
VALUE adjustement, it is enoght to select to
cursor below and set the value with the  /  keys of the remote
control.
Associated to the 
NOISE REDUCTION there is the possibility to use the
specific function 
(FLESH TONE CORRECTION) to make skin tone more
natural. Often the use of noise reduction filter slightly degrades
the image in those areas where skin tones are visible. With the
use of this function it is possible to maintain an excellent image
quality throughout the entire projected image.
