  • Page 8: Software Query

    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. By default the station filter is switched off. This results in data overflows at the output if you take the cassette in operation without corresponding settings.
  • Page 9 2.6 h tPs t h e m o d u l e wo r ks 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 with all their components (video, audio, data and service information), which can be changed using the TPS module.
  • Page 10 s s e m b l y When using quadruple cassettes in stations with more than eight slots, a maxi- mum of 8 cassettes may be operated, to prevent overloading the power supply and overheating the head-end station. All other slots must remain free! 3.1 i n s ta l l i n g t h e C a s s e t t e – 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.
  • Page 11 3.2 emC r e g u l at i o n s 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. The attenuation of shielding of the connection lines for ASI and antenna must meet the requirements for "Class A". CLASS • 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.

  • Page 13 3.5 r Ca e t r o f i t t i n g m o d u l e The cassette is equipped with two common interfaces. This allows you to con- nect two CA modules for various scrambling systems and service providers. Scrambled channels can only be descrambled with a CA module suitable for the scrambling system and the corresponding smart card.
