Power supply
• The compact multiswitches are powered via an energy-saving switch mode power
supply (voltage range 100...240 V, 50...60 Hz).

Remote power
The multiswitch supports 3 LNB-supply modes:
12 V: all 8 IF-inputs provide 12 Volts remote
voltage (mode for SMATV-LNBs)
18 V: the vertical IF-inputs provide 12 Volts,
the horizontal inputs provide 18 Volts
(mode for Twin-LNBs)
22 kHz: as 18 Volts mode, but high-band
inputs are modulated with 22 kHz
(mode for Universal-LNBs)
The selected LNB mode does not effect the
IF-selection logic.
!
• The total current load for the LNBs must not exeed 1 Ampere
(maximum 500 mA per connector).
Standby mode
• The multiswitch system supports a standby mode. The Sat-IF amplifiers and the LNB
remote voltage are only available when at least one receiver feeds a remote voltage to
its multiswitch outlet. Cascaded multiswitches activate upper devices via a control voltage
on trunkline 1.
• The rising remote voltage from the receiver causes a reset signal for the corresponding
DiSEqC microcontroller. The controller restarts in backwards compatible mode (see
analogue control signals).
• The terrestrial distribution is not effected by standby mode.
