Caution

• Assembly, installation and servicing should be carried out by authorised
electricians.

• Switch off the operating voltage of the system before beginning with assembly
or service work or pull out the mains plug.

• Do not perform installation and service work during thunderstorms.

• Install the system so it will not be able to vibrate…

- in a dust-free, dry environment

-

in such a manner that it is protected from moisture, fumes, splashing water and

dampness

- somewhere protected from direct sunlight

2.4 Description

The twin transmodulator cassette is a QPSK-converter, which converts all sta­tions modulated according to DVB-S
lated cable signals.

The

cassette

standard and

QPSK

into two

QAM

has two digital SAT IF inputs and an HF output.
It is equipped with two channel strips (“A” and “B”). Each channel strip consists
of a digital tuner, a digital signal preparation unit and a modulator.
The prepared input signals reach the HF output collector of the head-end station
via the HF output socket. The common output level of the channel strips can be
set at the output collector of the head-end station.
Two LEDs indicate if the respective channel strip is switched on (LED illuminates)
or off, and also provide an indication of the signal quality based on their
colour. Additionally the quality of the data stream received is displayed
(“CN…”).
The output symbol rate is fixed to a value of 6900 kSymb/s. If the symbol rate
being transmitted exceeds this value change to a high-order modulation (e.g.
from 64 QAM to 256 QAM).
When the head-end station is switched on, the two-line LC display shows the
software version of the control unit.
To operate this cassette the software version of the control unit must be “V 37”
or higher. You can find the current operating software for the control unit and
the cassette, the software “BE-Flash”

and the current assembly instructions
website “www.gss.tv”.
The

cassette is

designed for use in the following head-end stations:
– STC 1200
– STC 316
– STR 19-8

-modu-

on the

2.5 Software query
Control unit

If necessary, you can activate the indication of the software version of the con­trol unit manually:

• Press any two keys on the control unit of the head-end station simultaneously
until the display goes dark and

the software version, e.g. “

CLASS

KLASSE

3.1 Installing the cassette
– Ensure the head-end station is mounted so it will not be able to vibrate.

Avoid, for example, mounting the head-end station onto a lift shaft or any
other wall or floor construction that vibrates in a similar way.

– Before installing or changing a cassette unplug the power cable from the

mains power socket.

• Remove the fastening screws

1 of an unoccupied slot from the bracket of the

head-end station.

• Insert the cassette in this slot and push it into the housing.

• Align the cassette and apply slight pressure to connect it to the connections of
the board and the HF bus bar.

• Fasten the cassette with the 1 screws.

3.2 EMC regulations
To comply with the current EMC regulations, it is necessary to connect the

lines leading in and out of the head-end station using F terminals.

The attenuation of shielding of the connection lines must meet the require-

KLASSE

CLASS

ments for “Class A”.

When mounting the cassette in a STR 19-8 head-end station which is in-

stalled in a 19” cabinet, make sure the connections leading in and out for
the 19” cabinet are made using F terminals.

- 6 -

- 7 -

• Insert the required number of F terminals in the openings provided in the
head-end station or in the 19" cabinet.

—> F terminals are not included in the scope of delivery.

3.3 Connecting the cassette

Tighten the nut on the F terminal until the teeth on the lock washer have pen­etrated the exterior coating and a good connection is made between the
housing and F terminal.

5.1 Preparation

• Connect the test receiver to the HF output or the test output of the head-end
station.

• Set the output channel / output frequency of the

cassette

adjust the TV test receiver to this channel / frequency.

•

Switch on the channel strip (modulator) if necessary (s. page 15). For each
channel strip, there is a status LED which indicates if the channel strip is
switched on.

(page 14 / 15) and

• Balance the output levels of the channel strips “A” and “B” if the difference in
level is ≥ 1 dB (page 15).

5.2

Notes on level setting

In order to prevent interference within the head-end station and the cable sys­tem, the output level of the QPSK-QAM module must be lowered by 10 dB
compared to analogue modulators at 64 QAM, and by 4 dB compared to
analogue modulators at 256 QAM.

• Measure the output levels of the other

cassettes

and tune them to a uniform
output level using the appropriate level controls or software dependent on the
head-end station used.

Please regard the assembly instructions of the respec-

tive head-end station.

Selecting channel / frequency setting

In this menu, you can choose the channel or frequen cy setting
for the adjustment of the HF output. The channel setting cov­ers the range of channels S21 … C69, the frequency setting
covers the range from 42.0 MHz to 860.0 MHz.

The QAM signal is normally transmitted with a bandwidth of
8 MHz. This means that you can only use the channel centre
frequency of the existing channel raster in the range of chan­nels S21 … C69 (frequency raster 8 MHz). The CCIR chan­nel raster is 7 MHz in the range of the lower frequency bands
(channels C2 … S20). Therefore the frequency setting is used
here. If one uses the existing channel raster of 7 MHz in these
channel ranges, this will result in interference (overlapping)
with the 8 MHz QAM signal packages, thus causing trans­mission problems.
