1 safety regulations and notes
• Assembly, installation and servicing should be carried out by authorised
electricians.
• Switch off the operating voltage of the system before beginning with assem-
bly 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 wa-
ter and dampness
- somewhere protected from direct sunlight
- not within the immediate vicinity of heat sources
- in an ambient temperature of 0 °C to +50 °C. In case of the formation of
condensation wait until the system is completely dried.
• Ensure that the head-end station is adequately ventilated. Do not cover the
ventilation slots.
• Beware of short circuits
• No liability is accepted for any damage caused by faulty connections or
inappropriate handling.
• Observe the relevant standards, regulations and guidelines on the installa-
tion and operation of antenna systems.
• The standards EN/DIN EN 50083 resp. IEC/EN/DIN EN 60728 must be
observed.
• For further information please read the assembly instructions for the head-
end station used.
• Test the software versions of the head-end station and the cassette and
update them if necessary. The current software versions can be found at
"www.gss.de/en".
Take action to prevent static discharge when working on the device!
Electronic devices should never be disposed of in the household rubbish. In
accordance with directive 2002/96/EC of the European Parliament and the
European Council from January 27, 2003 which addresses old electronic and
electrical devices, such devices must be disposed of at a designated collection
facility. At the end of its service life, please take your device to one of these
public collection facilities for proper disposal.

2.4 desCriPtion
The twin transmodulator cassette is a converter, which converts signals modu-
lated according to DVB-C/C2/T/T2
standard into two COFDM modulated sig-
nals for feeding into a cable network.
The
cassette
has two digital RF inputs and
one RF output.
Two common interfaces are present to descramble scrambled channels.

general
The cassette is equipped with two channel strips ("
A
" and "
B
").
Using ad-
equate CA modules scrambled channels can be descrambled via tuner "A"
and "B".
LEDs provide an indication of the input signal quality based on their colour
and indicate if the respective channel strip is switched on (LED illuminates) or
off (see Fig. on page 11).

Data rate overflow (output)
Off Channel strip (modulator) off
The integrated TPS module (Transport Stream Processing) processes the data
of the transport streams.
Channel as well as frequency setting is possible for modulators.
The COFDM modulated RF output signals are sent through the RF output of the
cassette to the output collector. The common output level of the channel strips
can be set at the output collector.
The control of the cassette takes place via the control unit of the head-end station.
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 ver-
sion of the control unit must be "V 45" or higher. You can find the current op-
erating software for the control unit and the cassette, the software "BE-Flash"
and the current assembly instructions on the website "www.gss.de/en".
The cassette is intended for use in the
PROFI-LINE
head-end stations.
2.5 soft ware 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. "V 45" appears.
Cassette
The software version of the cassette is shown in the display after activating the
cassette (see page 18).

2.6 how the tPs module works
After decoding the input signals, the demodulated data streams can be ac-
cessed via the integrated TPS module. These data streams, also called trans-
port streams, contain several stations in all their components (video, audio,
data and service information), which can be changed using the TPS module.
station filter
Individual stations can be deleted. This reduces the data rate and, conse-
quently, the output symbol rate.
Changing the tr ansPort stream and orgnet-id
The transport stream ID can be changed. If the stations of a transponder are
split into the transport streams of different channel strips, a new identification
must be allocated to the "new" transport streams to realise the channel search
of the settop boxes connected without mistakes.
If the ORGNET-ID is changed a new NIT must be generated.
Changing the nit
The transport stream contains data in the form of tables which the receiv-
ers evaluate and require for convenient use. The TPS module can adjust the
"Network Information Table" (NIT) to accommodate the new station data. The
"NIT" contains data which is required by the set-top boxes connected to the
cable network for the automatic search feature.

3 assembly
3.1 installing the Casset te
– 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 screws 1.

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 cable terminals.
When mounting the cassette in a head-end station which is installed in a 19"
cabinet, make sure the connections leading in and out for the 19" cabinet are
made using cable terminals.
CLASS
KLASSE
The attenuation of shielding of the connection lines for ASI and antenna must
meet the requirements for "Class A".
• Insert the required number of cable terminals in the openings provided in
the head-end station or in the 19
"
cabinet.
Tighten the nuts on the cable terminals until the teeth on the lock washer have
penetrated the exterior coating and a good connection is made between the hous-
ing and cable terminals.
