Multiswitch (4 Satellites)
A3.5.3
This type of multiswitch allows to distribute the signal coming from 4 different
satellites. It uses a combination of OPTION, POSITION, Polarisation and Band
commands. The TV Explorer allows to use easily this type of multiswitch thanks
to the « OPT/POS » command, which sends the OPTION et POSITION commands
in the necessary order. Like in the others multiswitch, if itis wanted to change of
band or polarisation, if the satellite is even he himself, is necessary to send
OPT/POS command to cause the commutation again.
