Manual
: Except for the GPI trigger in
Edge
mode,
the manual switching action always provides the
input switch regardless of whether the input is safe
or not. For the GPI trigger in
Edge
mode, the switch
request may be refused by Amethyst III if the input is
not safe.
Redundancy
: the on-air TS input remains on-air
while it is safe.
Main/Spare
: the main TS input is on-air when it is
safe. When it is erroneous, the back-up TS input
becomes on-air, until the main TS input is safe again.
Mode
Automatic
Manual: GPI trigger, front panel, Web GUI, SNMP
