POSITIONING THE TWO UNITS
The  HT500LINK  system  consists  of  two  separate  units  (the  DigiOptic™  Image  Processor  and  the  Projector),  each  of  which  is 
equipped with a power cable; the two units are interconnected by a 20 m fibre optic cable.

POSITIONING PROJECTOR
Position  the  projector  on  a  stable,  suitable  platform  or  utilise 
the optional bracket for a fixed ceiling installation.
CAUTION:  In the case of ceiling mounting using a suspen-
sion bracket, follow the instructions carefully and comply with 
the safety standards you will find in the box together with the 
bracket. If you use a bracket different to the one supplied by 
SIM2 Multimedia, you must make sure that the projector is at 
least 65 mm (2-9/16 inch) from the ceiling and that the bracket 
is not obstructing the air vents of the projector.
Position the projector the desired distance from the screen: the 
size of the projected image is determined by the distance from 
the  lens  of  the  projector  to  the  screen  and  the  zoom  setting. 
See ADDITIONAL INFORMATION for more information.
POSITIONING  DIGIOPTIC™ IMAGE PROCESSOR
The  ideal  location  for  the  DigiOptic™  Image  Processor  is  on 
a  cabinet  shelf  or  on  a  rack  (dimensions  compatible  with  a 
standard 19" rack). Make sure that the support surface is stable 
and  that  the  unit  has  sufficient  space  around  it  for  ventilation 
purposes (at least 3 cm). 
The unit is connected to the mains via an external power supply 
unit with an output of +7 Vdc; the unit’s main power switch is 
on the power supply unit.Connect the power supply unit output 
cable to the POWER socket located on the rear panel (Fig. 2). 
Use  exclusively  the  power  supply  unit  provided  with  the  sy
-
stem  or  an  alternative  power  supply  unit  expressly  approved 
by SIM2.
To  mount  the  DigiOptic™  Image  Processor  on  an  equipment 
rack  use the screws and RH / LH supports supplied with the 
appliance.  Unscrew  the  screws  that  secure  the  cover  to  the 
DigiOptic™  unit  base,  position  the  RH  and  LH  supports  and 
fix  into place with the supplied screws. To secure the unit to 
the  rack use the supplied screws 
(Fig.6).

CONNECTING THE TWO UNITS
The system can be fully controlled using the supplied IR (infra
-
red) remote control handset. There is a single remote control 
for both the DigiOptic™ Image Processor and the Projector; the 
remote control can be directed towards either unit since they 
are both equipped with an IR sensor.
The  connection  between  the  two  units  is  made  with  a  single 
cable  containing  three  fibre  optic  cables  each  terminating  in 
an  LC  connector.  The  standard  cable  length  of  20m  will  be 
sufficient for most installation requirements. 
During installation of the fibre optic cable:
•   The individual optical cables are delicate: always handle 
the main cable without touching the individual optical ca
-
bles (Fig. 7). 
  Never  pull  the  individual  optical  cables  or  connectors;  if  necessary, you may pull the main three-core cable.
•  Check that the connectors are correctly inserted. 
•  Make sure that the cable does not constitute an obstacle 
for persons moving around the room. 
•  Take  care  not  to  create  knots  in  the  cable;  the  minimum 
radius of bends in the cable is 2 cm. 
•  Prevent the cable from pulling and mechanical stress: this 
could  cause  the  connectors  to  be  pulled  out  and  dama
-
ged.

•  Only remove the cap protecting the connector ferrule im-
mediately  before  inserting  the  connector;  if  the  ferrule  is 
allowed  to  come  into  contact  with  foreign  material  it  may 
be damaged, making the connector unusable.
•   Take particular care when inserting fibre optic connectors in 
their respective sockets on the rear panel of the DigiOptic™ 
Image Processor and the rear panel of the Projector. 
•  Make sure that the single optical cables are not switched: 
the  numbers  on  the  cables  must  match  the  numbers  on 
the connectors (Fig.8-9).

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 HT500 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.  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  HT500 LINK system is equipped with an excellent 
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
).

VIDEO 1 2 
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 3 4 
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 5 6 7 8   
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 
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 HT500LINK system rather than on the source because the 
HT500LINK 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 HT500LINK system 
in the two cases: deinterlacing performed by the HT500 LINK 
system (thanks to Faroudja DCDi™ technology) is often more 
effective  than  that  performed  at  the  source  (typically  a  DVD 
player)
GRAPHICS RGB 9 10  
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 11  
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 HT500LINK 
system.
HDMI 12 
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  HT500 LINK system of control data to optimise 
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 Processor
 
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.

The  HT500LINK  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). 
After a few seconds (system initialisation interval), the DigiOp
-
tic™  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
.
Table  3
If  the  No  optical  link   or Error   signals  are  active  the  system 
cannot be operated; if the  Warning signal is active the system 
will operate but it may be unable to read certain input signals 
correctly.

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 HT500LINK 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).
Avoid placing obstructions between the remote control and the 
infrared sensor at the front of the projector; this will impair the 
remote control performance.
