This command is sent by the
STB in order to set the
STM8SPLNB1 application
number. If the data2 value
corresponds to the
STM8SPLNB1 AppliNum, then
the STM8SPLNB1 commands
SaTCR indicated in data1 to
send a tone having frequency:
F = BPF
20 MHz).
This command is sent by the
STB in order to set the L.O.
frequencies present in the LNB. If
the data2 value corresponds to
the STM8SPLNB1 LOfreqNum,
then the STM8SPLNB1
commands SaTCR indicated in
data1 to send a tone having
frequency: F = BPF
F = (BPF + 20 MHz).
When receiving this command
the STM8SPLNB1 commands all
connected SaTCRs to send a
tone in order to indicate their
respective BPF
frequencies.
