3.2.2.4 1:1 Redundant Mode
The redundancy feature is a functional mode. However the redundancy feature does not fully utilize all features
of the RC-1260.
NOTE: The redundancy feature in the RC-1260 is not recommended.
The requirements are to set the priority switch to the main LNA/LNB. Then, wire the waveguide switch coils
and indicator appropriately. The unit behaves like a 1:2 configuration when the non-priority LNA/LNB has
failed. The unit then waits for the priority LNA/LNB to fail before the unit switches over and returns to manual
mode.
3.2.2.5 1:2 Redundant Mode
In this mode, three LNAs are configured with two LNAs on line and one powered LNA/LNB. However, the
LNAs are on stand-by. The operator must select which LNA/LNB has priority, 1 or 2.
If the priority-selected LNA/LNB fails, the backup LNA/LNB will switch the unit on line for that LNA/LNB.
The backup LNA/LNB will then change the system to the manual mode.
If the non-priority LNA/LNB fails, the backup LNA/LNB will switch to priority, but the unit will remain in the
auto mode.
When the priority LNA/LNB fails, the backup LNA/LNB will leave the non-priority LNA/LNB failed as well.
The unit then switches to the backup LNA/LNB and is changed to manual mode. If the backup LNA/LNB
should fail while the LNA/LNB is in the backup position, the unit will switch to manual mode.
