The RTX system combines the signal processing capabilities
of  the  DigiOptic™  Image  Processor  with  the  high  fidelity
reproduction of the DLP™ technology Display by linking the
two units via a fibre optic cable.
The  DigiOptic™  Image  Processor,  which  should  be  ideally
located close to the signal sources, supports and processes a
wide range of video signals, transmitting them to the display by
means of a fibre optic link cable.
The large number of inputs available (2 Composite Video inputs,
2 S-Video inputs, up to 4 Component or RGB inputs, 2 graphic
RGB inputs and 1 DVI-D input,1HDMI™) ensures the system
supports a  wide variety of analogue and digital sources: DVD
players,  VCRs,  satellite  and  terrestrial  receivers,  computers,
game consoles, video cameras, etc.
The  signal  processing  capabilities  of  the  Image  Processor
ensure optimum reproduction of a broad range of input signals,
from interlaced video to high definition and graphics.
Conversion of interlaced video signals to progressive signals
by  means  of  prestigious  DCDi™  technology  produces  fluid,
natural, images free of flicker and stairstepping artefacts.
Faithful reproduction of signals at higher resolutions (such as
high  definition  video  and  graphics)  occurs  without  loss  of
information  or  reduction  of  image  sharpness  thanks  to  the
processor’s high pixel rate signal acquisition capabilities.
Adaptation of the input signal resolution to the Display resolution
occurs without alterations of image quality, in accordance with
an ample choice of aspect ratios, including several definable
by the user.
All image adjustments can be performed with the remote control
with the aid Ôf the On Screen Display; alternatively, the unit
can be controlled by from a home automation system through
the serial port.
The Display, with its elegant and original design, produces an
image using the very latest Texas Instruments DLP™ technology
(1280x720  pixel  DMD™  panel  with  12°  technology),  a
proprietary  dust-sealed  optical  system,  a  new  six-segment
colour wheel and a new type of Fresnel lens. All these features
combine  to  provide  a  top  quality  image,  with  definition,
sharpness, colorimetry and contrast on a par with the famous
frontal Displays in SIM2’s Grand Cinema line.
The two units are connected via a three-core fibre optic cable
for transmission of the digital signal from the DigiOptic™ Image
Processor to the Display and control signals in both directions.
Transmission occurs without interference or attenuation over
distances of up to 500 m.
Moreover, the flexibility and small size of the cable allow the
maximum freedom when installing the system in your home.
SIM2 carries out comprehensive functional testing
in order to guarantee the maximum product quality.
For this reason, when you start using the product
lamp operating hours may already be at between
30 and 60.
In addition to the regular tests, the Quality Control
department performs additional statistical tests at
the time of shipment.
In this case the packing may show signs of having
been opened, and the accumulated lamp operating
hours may be slightly higher than the hours associ-
ated with the standard tests.

The RTX system consists of two separate units (the DigiOptic™
Image Processor and the Display), each of which is equipped
with a power cable; the two units are interconnected by a 20 m
fibre optic cable.
The ideal location for the DigiOptic™ Image Processor is on a
cabinet shelf or on a rack (dimensions compatible with a stan-
dard 19" rack). Make sıre 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. 6).
Use exclusively the power supply unit provided with the system
or an alternative power supply unit expressly approved by SIM2.
The Display is designed to stand on the floor. Place the Display
on  a  flat,  level  surface  where  it  has  sufficient  space  for
ventilation;  to  prevent  glare  and  reflections,  avoid  places
exposed to direct sunlight or intense light sources.
The mains power input socket and the power switch are both
located on the rear panel.
Adjust  the  rear  feet  to  obtain  the  optimum  viewing  angle  in

accordance with the distance and height of the viewing position
in front of the Display (Fig. 2).
The  system  can  be  fully  controlled  using  the  supplied  IR
(infrared)  remote  control  handset.  There  is  a  single  remote
control  for  both  the  DigiOptic™  Image  Processor  and  the
Display; 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 20 m 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 cables (Fig. 3). Never
pull the individual optical cables or connectors; if necessary, you
may pull the main three-core cable.

immediately 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
Display (Fig. 4).
• Make sure that the single optical cables are not switched: the
numbers  on  the  cables  must  match  the  numbers  on  the
connectors.
• Check that the connectors are correctly inserted.
• Use the cable clamps on the rear panel of the Display to
• 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 damaged.
After removing the protective caps from the fibre optic cable
connectors  and  the  panel  connectors,  insert  the  fibre  optic
connectors carefully, matching the numbers shown on each
element (Fig.4). Be very careful when handling optical fibres
