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 
frame  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
For 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 achie
-
ved 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 E-LINK system, 
connect the various signal sources using good quality cables 
designed for video applications (rated impedance 75Ω).
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.  Ge
-
nerally,  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 E-LINK system is equipped with an excel
-
lent Video Decoder and Deinterlacer and therefore even inferior 
quality signals will produce high quality results.
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).

source connector
VIDEO 1 2 3 
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 4 5 
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 prefe
-
rable because it offers a clearer and sharper picture.
COMPONENT / RGBS 6 7 8 9
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: compo
-
site  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  pro
-
gressive 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 E-LINK system rather than on the source because the 
HT300 E-LINK system is equipped with Faroudja’s sophisticated 
directional correlation deinterlacing technology (DCDi™).
Progressive signals usually provide better quality than interla
-
ced  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 E-LINK system 
in the two cases: deinterlacing performed by the HT300 E-LINK 
system (thanks to Faroudja DCDi™ technology) is often more 
effective  than  that  performed  at  the  source  (typically  a  DVD 
player).
RGB GRAPHICS 10 11 
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 synchro
-
nisation or composite H+V.
The video or graphic signals that can be connected to this input 
can have horizontal scan frequencies (H-sync) of between 32 
and  80  kHz  and  a  vertical  frequency  (V-sync)  of  between  48 
and 100 Hz. Image resolution can vary between 640x480 and 
1600x1200 pixels (VGA, SVGA, XGA, SXGA, UXGA).

DVI-D 12
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 E-LINK system.
HDMI 
With this input it is possible to integrate the optimal quality of a 
digital image with a multichannel audio signal. 
The  HDMI™  (High  Definition  Multimedia  Interface)  in  fact  in
-
tegrates  a  multichannel  audio  signal  with  the  uncompressed 
high definition video signal.
The  interface  also  allows  the  exchange    between  the  video 
source and the  HT 300 E-LINK system of control data to opti
-
mise the quality of the projected image.
The HDMI™ input allows connection to video sources that use 
the HDCP (High-Bandwidth Digital Content Protection) protocol 
to protect their contents. This protocol is in fact incorporated in 
the definition of  the HDMI™ technology.
Once  the  video  source  has  been  connected  to  the  HDMI™ 
input, internal processing by the  DIGIOPTIC IMAGE PROCES
-
SOR separates the video information from the audio information. 
This  information  is  then  made  available  via  an  optical  digital 
output  with  a  female  TOSLINK  connector  in  accordance  with 
the  S/PDIF standard.
CONTROL (RS232)
The system can be controlled via a personal computer or home 
automation  systems  by  means  of  the  serial  port:  simply  con
-
nect this 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.

  HT300  E-LINK  system  consists  of  the  Projector  and  the  Di-
giOptic™  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 sen
-
sors 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).

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).

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 affec-
ting 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.
MAIN MENU
To access the main menu of the On Screen Display press the 
MENU key on the keypad or the MENU+ or MENU- key on the remote

COLOR
This control (also called Saturation) increases or decreasethe 
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 adjust
-
ment 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    ap
-
pear 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  or  DVD  players.  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 
fl / ‡ 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.
