Page 8: 2.4.3 General
To operate this cassette the software version of the control unit must be "V 41" 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 on the website "www.gss.de". The cassette is designed for use in the following head-end stations: PSU 12, PSU 8, PGT 8 and PST 19-1. -
Page 9: Assembly
Assembly 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. -
Page 10: Connecting The Cassette
The operating software of the cassette can be updated via the 9-Pin D- SUB socket "RS 232" using a PC or laptop and the software "BE-Flash". You can find the current operating software and the software "BE-Flash" on the website "www.gss.de". The LAN socket and the slot for a CA module are without function. -

Page 12: Programming
Programming 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 (see page 19) and adjust the TV test receiver to this channel. • Switch on the channel strip (modulator) if necessary (see page 19). For each channel strip, there is a status LED which indicates if the channel strip is switched on. -

For this setting please take the required information from the documentation (technical data) of the ASI component to be connected. Bx 4 ASI OPTION 188 pos. cont. • Press the buttons to set the size of the data packets ("188" or "204" bits). • If the polarity of the data to be transmitted has to be changed, press the buttons to place the cursor under "pos."... -

• Press the button. —> The "Selecting channel / frequency setting" – "OUTPUT" menu is acti- vated. Selecting channel / frequency setting In this menu, you can choose the channel or frequen c y setting for the adjust- ment 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 …... -
Page 19: Setting The Output Channel
Setting the output channel In this menu you set the output channel of the channel strip. Additionally the modulator of the channel strip can be switched off or on. Bx 4A OUTPUT • Use the buttons to set the output channel. Setting the output frequency In this menu you set the output frequency of the channel strip (42.0 … 860.0 MHz). -

Page 21: Setting The Input Symbol Rate
Setting the input symbol rate Setting the DVB mode The symbol rates of the satellite transponders can be found in the current chan- nel table of the satellite operator, in various satellite magazines and in the Internet. The cassette recognizes the transmitted DVB mode and switches over between the normal QPSK mode (DVB-S) and the DVB-S2 mode. Receiving stations with DVB-S2 mode, we suggest to preset the DVB mode to shorten the time for searching stations. -
Page 22: Testing The Signal To Noise Ratio
• Use to position the cursor under the digits of the frequency display to be set. • Press to set the input frequency. • Set the frequency offset shown in the display (e.g. "– 1.8") to less than 1 MHz by varying the input frequency using the buttons. -

Setting "MIX+TABLES": In addition to the functions of the "MIX"... -
Page 24: Setting The Qam Modulation
Setting the QAM modulation Inverting the user signal In this menu, you can set the QAM modulation and invert the user signal. For exceptional cases and "older" digital cable receivers, the spectral position of the user signal can be inverted. Bx 4A 256-QAM normal Setting the QAM modulation to set the QAM modulation ("4" … "256"). • Use —> For higher QAM modulation, the output symbol rate is lowered. —> An output QAM modulation of > 64 QAM places a large burden on the cable network. Due to noise, delay and frequency response problems, reception of the converted output signal can be impeded. - Page 25 input signal therefore must be built in such a way so that the output symbol rate set ("Number 1") is not exceeded. The symbol rates of the transport streams built by the cassette can be measured at the setting "OUTROUTE ASI=>ASI" and be displayed in the respective channel strip. • Use the buttons to place the cursor under the number to be changed ("Number 1") and set the symbol rate with the buttons...
