You can find the current operating software for the control unit and the cassette, the software “BE-Flash” and the current assembly instructions on the website “www.gss.tv”. The cassette is designed for use in the following head-end stations: – STC 1200 –...
2.5 Software query Control unit If necessary, you can activate the indication of the software version of the con- trol 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 37” appears. 2.6 How the TPS module works After decoding QPSK- or 8PSK-modulated signals, the demodulated data stream can be accessed via the integrated TPS module.
2.7 Explanation of the term “symbol rate” Modulation schemes such as QPSK and QAM transmit multiple bits simultane- ously. These are referred to as symbols. In addition to the user data flow which transmits video and audio information, error correction bits are transferred. The FEC number states the ratio of user bits to the complete transmitted bits.
2.8 Bandwidth-efficient assignment of cable channels with low bandwidths (SelecPlex ® Channels with low bandwidths are the result of filtering out stations which are not required. These “narrow” channels can then be arranged in one channel to save space. To do this, activate the “Setting the output frequency” menu (assign- ment outside the official channel raster).
Assembly 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. –...
The operating software of the cassette can be updated via the 9-Pin D-SUB socket “RS 232” using a PC or notebook and the software “BE-Flash”. You can find the current operating software on the website “www.gss.tv”. - 11 - - 11 -...
3.4 Retrofitting a CA module The cassette is equipped with a common interface. It allows you to connect a CA module for various encryption systems and service providers. Encoded channels can only be decoded with a CA module suitable for the encoding system and the corresponding smart card.
The control panel at a glance 4.1 Menu items Program the cassette using the buttons on the control unit of the head-end station. The two-line display of the control unit then shows the menus. The parameters and functions to be set are underlined. Use the key to select the following main menu items: –...
Programming 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 (s. page 20 / 21) and adjust the TV test receiver to this channel. •...

5.4 Programming the cassette —> Pressing the button for longer than 2 seconds cancels the pro- gramming procedure. This takes you back to the program item “Selecting the cassette” from any menu. Any entries that have not been saved are reset to the previous settings.
Selecting the channel strip Bx 4A DVBS2-TPS A / B • By pressing , select channel strip “A” or “B” —> The display shows e.g. the menu “Bx 4A DVBS2-TPS”: “Bx” stands for cassette (box), “4” for slot 4 “A” for channel strip “A”...

Setting the output frequency In this menu you set the output frequency of the channel strip (42.0 … 860.0 MHz). Additionally the modulator of the chan- nel strip can be switched off or on. Bx 4A OUTPUT ◀ ▶ ◀ ▶...
• Measure and note down the output level of the channel strip. • Save the settings by pressing the button. • Select the other channel strip (page 19), measure and note down its output level. • Activate the “LEVEL” menu of the channel strip with the higher output level.
Setting the input symbol rate The symbol rates of the satellite transponders can be found in the current channel table of the satellite operator, in various satellite magazines and in the Internet. Bx 4A SYMBOL ◀ ▶ ◀ ▶ 27500 DVB-S DVB-S / DVB-S 2 •...
Setting the input frequency If three dots “ … “ appear in the second line of the display, the cassette is in the “station search” mode. Please wait until the process has finished. Once the HF receiver has synchronised to the input signal, any offset to the target frequency is displayed in MHz, e.g.

Bx 4A (+ 9.6) OK 12.0 dB Current signal to noise ratio This value shows the difference between the quality of the input signal and the threshold of the tuner at this type of modulation. At a value lower than “5” picture dropouts can oc- cur.
Setting the station filter The default setting for the station filter is “off”. In this menu you define the stations received to be transmitted. If stations are activated the output symbol rate increases. If the station filter is switched off (factory default) all stations of the transport stream passes the station filter.
