The default is Off.
The KPA output automatically muted in the
event of a detected fault. Auto Fault Recovery,
if enabled, will cause the output signal to go
active (unmuted) if all faults clear. If disabled,
the output will remain muted even after all
faults clear until a MUT_OFF command is
received.
6.9.3 Mode Commands
Note : There are two modes of operation that may intersect: Redundancy Mode and
Automatic Mode.
Redundancy Mode Comtech EF Data’s KPA family is designed to automatically sense and configure into redundancy mode when the
redundant loop cable is connected. Polling on the dedicated redundancy buss will not begin until the redundancy loop
cable is connected. Each KPA’s designation in a redundant subsystem is determined automatically via the
redundancy interface cable connected between the two (1:1 subsystem) or three (1:2 subsystem) KPAs in the
redundant subsystem.
Automatic/Manual
Mode Select Automatic Mode:
Confirmation:
Automatic Status:
Confirmation:
<DEV/SAM_y'cr' xxx
>DEV/SAM_y'cr'' lf']
<DEV/SAM_'cr'
>DEV/SAM_y'cr'' lf'] Where: y = A for Auto
M for Manual
The default is Off.
This command provides for automatic
switching by the backup KPA if both units are
in the Redundancy Mode. This command is
only accepted by the backup KPA. If a primary
KPA is set in Manual Mode and a fault occurs,
the backup KPA will log the occurrence and
not act upon further information from the KPA
until put into Automatic Mode.
Backup Mode Initiate a Backup:
Confirmation:
Retrieve Backup Status:
Confirmation: <DEV/FBU_x_y'cr'
>DEV/FBU_x_y'cr'' lf']
<DEV/FBU_'cr'
>DEV/FBU_zzzzz'cr'' lf'] Where: x = 1 or 2 KPA number.
Y = F to force a backup
N = to remove a backup
zzzzz = NONE, if no backup active.
ACTIVE, if an automatic backup
has occurred.
FORCED, if a forced backup is
active.
This command allows the user to force a
backup condition for mainternace and test
purposes. This command must be sent to the
KPA designated as the backup KPA to
configure the Waveguide switch to a position
such that the backup KPA is Online and the
primary KPA is Offline.
Priority Select Set Prority:
Confirmation:
Retrieve Prority Status:
Confirmation: <DEV/PRI_x'cr'
>DEV/PRI_x'cr'' lf']
<DEV/PRI_'cr'
>DEV/PRI_x'cr'' lf'] Where x = 1 or 2
This command allows the user to assign
prority when operating in a 1:2 redundant
subsystem. This command provides
arbitration in the event that both primary KPAs
are faulted simulataneously.
