1 Safety regulations
Caution
• The converter should be assembled, installed and serviced by authorised electricians.
• Switch off the operating voltage of the system before beginning with assembly
or service work or pull the mains plug.
• Install the system …
- In a dust-free, dry environment
-
In such a manner that it is protected from moisture, fumes, splashing water
and dampness
- Where it is protected from direct exposure to sunlight
- Not within the immediate vicinity of heat sources
- At an ambient temperature of below 50 °C
•
Make sure the device is sufficiently ventilated.
Do not cover the ventilation slots!
• Avoid short circuits!
• No liability is accepted for damage caused by faulty connections or inappropriate handling.
• Observe the relevant standards, regulations and guidelines on the installation and
operation of antenna systems.
•
Earth the SAT receiver by means of the equipotential bonding rail in accordance
with DIN EN 50083 and VDE 0855.
• Do not perform installation and service work during thunderstorms.
Take measures to prevent electrostatic discharge when working on the device!

2.3 Description
The cassette is used to feed standardised audio and video signals into a cable
system from completely different audio and video sources (e.g. audio and video
reproduction devices, test picture generators, observation cameras etc.).
Furthermore you can equip the cassettes with up to 3 modulators to modulate
the fed-in signals on up to 3 freely adjustable channels (refer to “Technical
specifications”).
The audio and video sig
nals which are fed in via the cinch sockets of the modulator are modulated to an adjustable carrier frequency in the modulator and
supplied to the combiner. They are brought together with the active signals from
the other modulators there and are sent to the HF output collector of the head
end via the HF output socket. The output level of the cassette can be adjusted
with the level regulator (max. –20 dB) at the output collector of the head end.
The software version of the control unit appears on the two-line LC display after
switching on the head end.
The cassettes are intended for operation in the following head ends:
– STC 316
– STC 332
– STC 1200
– STR 19–8
2.3.1 Display of the control unit software version
This cassette requires a control unit with the
V.34
software version or
higher.
The software of the control unit may have to be updated. The latest software can be found at: http://www.gss.tv
• To display the control unit‘s software version:
Press two control keys (e.g. ) simultaneously (for about 5 sec-
onds) until the display darkens and the software version “V.34”, fo r
example, is displayed.

Note
Observe the ESD protective measures!
Danger of cut injuries!
The cassette is made of punched stainless steel parts. Some of them may have
sharp edges.

ground connection Y in the
corresponding slot on the
board (Fig. 3). Pull the modulator about 1…2 mm away
from the combiner if necessary.
• Fasten the combiner U with
screws T (Fig. 2/3).

• Connect the HF output of the respective modulator to the HF input of the com-
biner with the corresponding HF cable.
• Plug the modulators B and A onto the corresponding terminal strips X of
the cassette board as illustrated in Fig. 4. Position the ground connections Y
of the modulators in the respective slots on the board.
