TECHNICAL CHARACTERISTICS
Analogue control signals:
14V/18V - polarization selection (vertical/horizontal)
0 kHz/22 kHz - band selection (low/high band)
22 kHz tone burst - satellite selection (satellite A/B)
DiSEqC control signals according DiSEqC 2.0 protocol for specifications (see
www.eutelsat.com
).
Without DiSEqC signal and tone burst only satellite A will be accessible.
Multiswitch has own power supply unit, which ensure feeding voltages: 18 V through H lines, 14 V through V lines and
12 V through active terrestrial TV input.
To improve isolation from other SAT TV lines put 75 Ohm terminations with DC blocking on idle connectors if they are.
