    The COFDM modulated HF output signals are sent through the HF output of the cassette to the output collector. The common output level of the channel strips can be set at the output collector. 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 44" 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.triax.com". The cassette is intended for use in CSE 3300 head-end systems. 2.5 s o f t wa r e q u e ry o n t r o l u n i t 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...
  • Page 8 2.6 h tPs t h e m o d u l e wo r ks After decoding QPSK- or 8PSK-modulated signals, the demodulated data streams and the data stream fed via the ASI socket can be accessed via the integrated TPS module. These data streams, also called transport 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. Additionally stations of the different transport streams can be assembled to a new transport stream. Tables are adjusted automatically.

    s s e m b l y 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 10 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. - 10 - CCS-2 1002...

Scrambled channels can only be descrambled with a CA module suitable for the scram- bling system and the corresponding smart card. The smart card contains all the information for authorisation, descrambling and subscription. Caution – Check with the distributor or manufacturer of the CA module to be used to ensure that it is suitable for decoding several channels. – The hardware and software of this cassette have been thoroughly prepared and tested. – Any changes made by programme provider to the structures in the pro- gramme data might impair or even prevent this function.
