Trunklines (SMS 9941 NF and SMK 99xx F) • Trunkline output 0 provides a remote voltage of 18 Volts (max. 500 mA) to supply cascaded multiswitches. The terrestrial trunkline must therefore be connected even if no terrestrial signals are distributed! • All trunklines (0...8) have to be terminated with the isolated terminations (ZFR 75 DC) supplied. • Unused inputs and taps (A...D/A...F/A...H) must be terminated for EMC conformity. Terrestrial • The terrestrial input has an adjustable attenuator (SMS types). The terrestrial amplifier is CATV-compatible (push-pull technique). • Turning the adjustable attenuator fully CCW, the terrestrial amplifier is switched off and bypassed (SMS 9401 / 9601 / 9801 NF only). Terrestrial distribution will then be completely passive and return-path compatible. • Aerial signals must be fed via diplexers or multiband-amplifiers (selective multibandamplifiers type MBV... / MVF... or selective FM devices as FM filter FMP 30 or FM amplifier VFM.. F). It is not recommended to connect an aerial directly. • Max. outputlevel - SMS 9941 NF (trunkline): MHz 47 - 450 47 - 606 47 - 862 dBµV / 60 dB / DIN EN 50083-3 dBµV / 1R8-15 IMA 3 IMA 2 CTB CSO CENELEC CTB 72 dB CSO 69 dB 109 108 104 106 A: 19 K 107 106 99 99 C: 29 K 106 102 97 93 E: 42 K 96 96 -- -- 97 1) 1) 96 1) 1TR8-1 (28 analog + 63 digital) at 60 dB - SMS 9401 / 9601 / 9801 NF (tap): MHz 47 - 450 47 - 606 47 - 862 dBµV / 60 dB / DIN EN 50083-3 dBµV / 1R8-15 IMA 3 IMA 2 CTB CSO CENELEC CTB 72 dB CSO 69 dB 89 88 84 82 A: 19 K 78 72 88 84 81 80 C: 29 K -- -- 86 81 80 75 E: 42 K -- --
SAT IF distribution • The IF amplifier units are equipped with a synchronous level adjuster for every IF pair to equalise different signal levels from the satellite systems. A level decrease up to 10 dB is possible. • The max. input level is typically 85dBµV for SMS 9941 NF and 92dBµV for SMS 9401 / 9601 / 9801 NF (max. channel occupation, level adjusters fully CCW). • The IF signals must be connected as shown on the case of the multiswitch to ensure correct access to the signals. • Max. outputlevel - SMS 9941 NF - SMS 9401 / 9601 / 9801 NF trunkline: tap: EN 50083-3 35 dB IMA 2 105 dBµV 110 dBµV 35 dB IMA 3 950 ... 2200 MHz 950 ... 2200 MHz EN 50083-3 35 dB IMA 3 88 dBµV 35 dB IMA 2 86 dBµV Multicarrier load: • For multicarrier load the maximum output level must be derated in assistance with the following table. Number of carriers Level reduction (dB) 2 3 4 6 8 10 16 24 36 0 2 3 5 6 7 9 10,5 12,5 Selection logic • The selection logics of different taps are totally independent and can be controlled by either the known analogue control signals or DiSEqC signals. • Switching is backwards compatible with the analogue control signals until a valid DiSEqC command is received. Analogue control signals will be ignored afterwards until a reset is done (interruption of the remote voltage or interruption of mains power or DiSEqC command 'Reset'). Mixed use of DiSEqC and non DiSEqC receivers is possible at the same tap when the remote voltage is interrupted when changing the receiver. • Analogue control signals: - 14 V/18 V polarity selection (vertical/horizontal) - 0 kHz/22 kHz band selection (low/high band) - ToneBurst satellite selection (Satellite A/B) • DiSEqC control signals: Polarity vertical/horizontal Band low band/high band Position A (east)/B (west)
