Setting Description
Backup receive frequency
1/2
This is the RF input frequency for the backup
carrier configuration.
Backup Symbol rate 1/2 This is the backup nominal symbol rate, used
when we fail to lock on the primary demodulator
parameters.
Carrier switch delay
This is the time interval (in seconds) between
consecutive demodulator carrier switch
operations.
When this time is to short the device is unable to
connect to the other frequency and can result in
permanent loss of satellite link connection.
By default this is 60 seconds.
Carrier switching enable Use this variable to enable or disable the
switching between the two demodulation carriers.
Carrier switch count The number of times we have dynamically
switched to another carrier (with or without
success).
