1 Safety regulations

Caution

• The converter should be assembled, installed and serviced by authorised elec-

tricians.

• 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 inap-

propriate 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 modu-

lator 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 soft-

ware 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”, f or

example, is displayed.

3 Installation

3.1 Installation of the modulators

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.

•

Screw 3 screws S (TORX TX6) out of the cassette cover (Fig. 1).

• Push the cassette cover to the rear and remove it.

Fig. 1

• Screw the fastening screws T out

of the combiner

U (Fig. 2).

• Take the combiner out of the cassette.

Fig. 2

• Plug the HF output of the modulator C onto the HF input

of the combiner

(Fig. 2 / 3)

- 7 -

ENGLISH

• Insert the HF output of the

combiner U into the open-

ing

W of the cassette frame

and connect the connec-

tions of the modulator with

the socket strip

X on the

cassette board. Position the

ground connection Y in the

corresponding slot on the

board (Fig. 3). Pull the modu-

lator about 1…2 mm away

from the combiner if neces-

sary.

• Fasten the combiner U with

screws T (Fig. 2/3).

Fig. 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.

Fig. 4

• Push the cassette cover from the back of the cassette into the guides and fas-

ten it with the 3 screws

(Fig. 1).
