Crystal Vision Introduction
FRX HD User Manual R1.0 306/09/2007
1Introduction
The FRX HD is a two-channel optical serial digital video receiver and distribution
amplifier for both High Definition and Standard Definition formats with up to two outputs
per channel.
The universal connection system allows a mixture of Crystal Vision modules in the frame.
The modules plug in the front and the rear connectors plug in the rear. Depending on
frame design, a hinged or removable front panel reveals LED indication of input and PSU
status when opened.
FRX HD two channel optical SDI distribution amplifier
The RM28 single slot rear connector provides two serial digital outputs per channel with
up to 24 modules in 4U of rack space.
The range of Crystal Vision optical boards has been designed to work in conjunction with
the Indigo 4 and the Indigo 2 and Indigo 1 frames of Issue 2 and above. The board may be
plugged into any of the PCB slots, the only proviso being where it needs to be placed
below a Standard Definition board. The rules governing frame configuration are
explained in the installation chapter.
The RM28 single slot rear connector provides two serial digital inputs and two optical
outputs with up to 24 modules in 4U of rack space.
Note: You can find the issue number of a frame inside at the front.
The Indigo frames have been designed to accept any selection of boards from our range of
Standard Definition, High Definition, audio and optical products. The high packing
density allows up to six modules in 1U, up to 12 modules in 2U and up to 24 modules in
4U.

Crystal Vision Introduction
FRX HD User Manual R1.0 406/09/2007
The main features of the FRX HD are as follows:
•Dual 1-in 2-out optical to HD/SD distribution amplifier
•LED optical input presence indication
•Selectable HD/SD slew rate
FRX HD
At the heart of the FRX HD is a two-channel state-of-the-art optical receiver module,
each channel consisting of an optical pin diode and signal conditioning circuitry coupled
to a two-output cable driver. The two identical channels of the FRX HD optical receiver
are completely independent of each other. Both channels are under the control of a CPU,
which monitors and reports their status.
FRX HD two-channel HD/SD optical receiver
Note: Caution must be taken when removing the FRX HD card if an optical
signal is present due to the possible damaging nature of high intensity light.
Although Crystal Vision optical products contain class 1 devices which are designed to be
safe under all circumstances, to avoid possible personal injury you are advised not to look
directly into a vacant optical slot where a third party piece of laser transmitting equipment
has been remotely connected to the Crystal Vision equipment.

Crystal Vision Hardware installation
FRX HD User Manual R1.0 506/09/2007
2Hardware installation
The Crystal Vision optical boards have been designed to work in conjunction with the
Indigo 4 frames, or Indigo 1 and 2 frames of issue 2 or higher. All modules can be
plugged in and removed while the frame is powered without damage.
Note: You can find the issue number of a frame inside at the front.
2.1 Handling
Due to its fragile nature, fibre optic equipment must be handled with care. Sharp blows or
snagging the fibre pigtails will fracture the internal glass filament and destroy its light
carrying ability. A degraded performance will also result if a build-up of dust and dirt film
on the connector ferrules is allowed to occur. It is strongly recommended that the supplied
dust caps are in place whenever the receiver card or rear module are de-mounted for any
reason.
PCB connectors with the dust caps fitted
The RM28 rear module is also fitted with dust caps on both sides of the optical connector.
The pair of dust caps that are internal to the frame must be removed before the rear
module is fitted. The external pair can then be removed when the fibre tails are connected.
It is also recommended that dust caps should be re-fitted if the fibre tails are to be
removed for any length of time. Should the FRX HD be removed for a while it is
recommended that the rear module should also be removed and stored with the dust caps
in place.

FRX HD User Manual R1.0 606/09/2007
RM28 rear module with dust caps fitted to both sides of the optical connector
2.2 Universal rear connectors
When using the RM28 single height rear connector, the 4U Indigo 4 frame will house up
to 24 modules and three power supplies. The 2U Indigo 2 frame will house up to 12
modules and dual power supplies, while the 1U Indigo 1 frame will house six modules
and a single or dual power supply. The Indigo DT desk top boxes do not currently accept
the Crystal Vision optical modules.
The Indigo frames have hinged front panels giving access to the PSU and all modules.
The universal frame wiring system allows any interface range modules to be fitted in any
position (1) with the use of pluggable rear modules.
(1) Due to height restraints, some restrictions apply when mixing optical modules with other Crystal Vision
modules.
Loading restrictions
The FRX HD can be loaded into any compatible frame’s slot but due to the extra height
of the FRX HD it is not possible to place cards from the Crystal Vision Standard
Definition or audio range directly above in certain positions. High Definition boards do
not share this restriction.
