Note: Using "Auto" will enable the backup functionality.
Note: When the backup functionality is being used, the user can choose which
Receive Group is being used as follows: setting the "Pri Group" to the desired
group or by setting the "Active Group" to the desired group, and then activating
the backup functionality again by setting the "Active Group" to "Auto."
Setting the Primary Receive Group
Note: The Receive Group that is not selected as the Primary Receive Group, will be
the Backup Receive Group.
1 Use the Up and Down buttons to move the cursor to "Pri Group," then press the
Enter button.
2 Use the Up and Down buttons to select "1" or "2," then press the Enter button to
save the selection.
Setting the Switchover Trigger
This sets the failure that is used to initiate a switchover to the backup. It is either a
failure of the Receive Group reception ("TrigTSErr") that is detected by a lack of TS
Presence in the Receive Group, or when the video cannot be decoded ("TrigDecErr").
When "TrigDecErr" is used, the "Pri Rest" (Primary Restore) will be set to "Never"
and the "Pri Rest" option is not presented. This is done because the Primary restore
uses the TS Presence ("TrigTSErr") to detect when the primary is present, and
unstable operation could take place if the switchover triggers are not consistent.
1 Use the Up and Down buttons to move the cursor to "SwtchOver," then press the
Enter button.
2 Use the Up and Down buttons to select "TrigTsErr" or "TrigDecErr," then press
the Enter button to save the selection.
Note: Using "TrigDecErr" sets "Pri Rest" to "Never" and it does not need to be
changed.
