3 1 Safety regulations Warning Assembly, installation and servicing must be carried out by an authorised electrician. Switch off operating voltage before the start of assembly or service work or pull out the mains plug. Install the system - in a dust-free, dry environment - so that it is protected from moisture, vapours, splashing water and damp - somewhere protected from direct sunlight - away from the immediate vicinity of heat sources - at an ambient temperature of < 50 C. Make sure the device is adequately ventilated. Do not cover the ventilation slots. Beware of short circuits! No liability is accepted for damage caused by faulty connection or inexpert handling. Observe the relevant norms, regulations and guidelines on the installation and operation of antenna systems. Earth the SAT receiver using the equipotential bonding rail in accordance with DIN EN and VDE Do not perform installation and service work during thunderstorms. Take action to prevent static discharge when working on the device. 2 General information 2.1 Packing contents 1 Cassette PSDP 1200 or PSDP 3200 or PSDP 4200 or PSDP HF cables (F-connector, screw connectors) 1 Assembly instruction 1 Measuring log ENGLISH

Each Cassette has two digital SAT ZF inputs and an HF output. Each Cassette is equipped with two channel strips (A and B). Each channel strip consists of a digital tuner, a digital signal preparation unit and an output converter. The channel strip A can decode encoded channels via a corresponding CA module. Depending on the hardware and CA module, two channels can be decoded simultaneously with a CA module, with the second one supplied via channel strip B. The control of the Cassettes takes place via the head end. By means of the a and b levels of the channel strips, channel selection according to a timer is possible. A Cassette s channel strips are indicated by Bx / Box A or B in the control unit display. The prepared input signals reach the HF output collector of the head end via the HF output socket. The common output level of the channel strips can be set with the level regulator (max. 20 db) at the output collector of the head end. When the head end is switched on, the two-line LC display briefly shows the software version of the control unit. The dialog guidance takes place in the 2-line LC display of the control unit. Approx. 5 minutes after the last button has been pressed, the display switches off automatically. Press any button to reactivate it. The Cassettes are designed for use in the following head ends: PSU 8 PGT 8 PSU 12 ENGLISH 1) DVB-S = Digital Video Broadcasting - Satellite 2) QPSK = Quadrature Phase Shift Keying

34 6 Technical terms in the digital transmission technology / satellite technology fields CA (Conditional Access) An encrypted digital channel (conditional access) can only be viewed with the CA module for the encryption system in conjunction with the corresponding smart card. The smart card contains all of the necessary subscriber and channel data for the authorisation and enabling of the corresponding channel provider. The digital encryption systems most commonly in use in Europe are: Conax, CryptoWorks, Irdeto, Nagravision, Seca and Viaccess. CI (Common Interface) The common interface slot (CI) is the interface for DVB receivers, into which a CA module of the various encryption systems can be inserted. DVB (Digital Video Broadcast) With DVB, the limited resources of terrestrial transmitters and satellite transponders can be used in a considerably more efficient manner. It is possible to store 6 digital TV and radio channels on one channel/transponder without compromising quality. FEC (Forward Error Correction) FEC is a standardised error protection system for digital television transmissions. In this process, redundant data (only back-up data containing no picture or audio data) is transmitted along with the original picture and audio data. This is necessary since there is no saved data protocol between the transmitter and the satellite receiver. If transmission faults occur, the receiver can reconstruct the missing information using the redundant data. The FEC describes the relationship of original picture and audio data to redundant data. An FEC of 3/4 states that a data volume consisting of 3/4 original data and 1/4 redundant data is being transmitted. Hierarchical modulation In order to attain with less field strength a greater range for broadcasters, with DVB- T so-called hierarchical modulation is used. In this process, several data streams are modulated onto a DVB-T data stream using Quadrature Amplitude Modulation (QAM). The robust High Priority data stream (HP) with a lower data rate is modulated onto the more sensitive Low Priority data stream, which possesses a higher data rate. In good reception conditions, the receivers can receive both data streams; in poorer reception conditions, only the HP portion. Several receivers can be supplied simultaneously with various services via one channel. MCPC (Multi Channel Per Carrier) This is a common process for accomodating several picture and audio channels on one carrier per transponder

35 MPEG (Motion Picture Expert Group) This internationally recognised norm group has created the basis for digital television (DVB) and many other interactive digital services. Digital television as it stands works with MPEG-2, where HDTV is also defined (see also ISO norm - ISO ). PID (Program ID) To be able to filter out a single channel from the data stream of an MCPC carrier, identity codes are transmitted for every channel for picture and audio transmissions (i.e. video PID and audio PID). The receiver has saved the PIDs in its channel list for every station and can route the correct data to the television. The PIDs are determined anew during every automatic search. In order to view a certain station, it may be necessary (only in exceptional cases) with some receivers to enter the PIDs manually. QPSK (Quadrature Phase Shift Keying) Quadrature Phase Shift Keying With QPSK, the carrier oscillation can take in four discrete phase conditions, which are allocated the four possible combinations or two consecutive bits of the binary code signal. This makes it possible to transmit two bits with one phase condition. Correspondingly, carrier oscillation phase jumps of 90, 180, 270 and 360 (0 ) are possible. The amplitude and frequency of the carrier oscillation therefore remain constant. SCPC (Single Channel Per Carrier) In an SCPC process, only one digital picture or audio channel is on one carrier. A number of carriers can be stored on one transponder. SR (Symbol Rate) The symbol rate specifies at which speed data is to be sent. The receiver must synchronise to this speed. Symbol rates between and kilosymbols per second are common for MCPC channels; SCPC channels work with symbol rates between 2000 and 7000 kilosymbols per second. Smart card Access/Authorisation card of a channel provider with which the paying subscriber can view the encrypted satellite channels of this provider. The smart cards contain a chip, in which all necessary subscriber and channel data for the authorisation and enabling of encrypted satellite channels are saved. Cyclical information is sent for all subscribers via the transmitter. The CA module filters the relevant information for the subscriber noted on the card and checks their authorisation. ENGLISH
