Note: A temperature fault is indicated if the unit is
≤ -20°C or ≥
85
°C. This creates a summary fault and will cause the unit to
mute itself and switchover to the back-up unit. However, the
9V supply to the FET transistors will remain on until the unit
reaches the thermal shutdown temperature of
≥ 90°C. For
protection reasons, the unit will shutdown the 9V supply to
the power transistors at temperatures at
≥ 90°C.
Summary Alarm
Status
Summary Alarm:
Confirmation:
Where: xx = Ok or FT
Summary Alarm is set to Fault (FT), if any of items in Alarm Status
are faulted.
Terminal Status
Change
Configuration Status:
Confirmation:
Where: nnn = Yes or No
The TSC_ command can be used to determine if the status of the
terminal has changed since it was last polled. If any of the
parameters listed in the RCS or RUS commands have changed as
a result of user operations or if any new fault conditions occur the
TSC_ command will return YES. The TSC_ command will then
continue to return YES until any of the following commands are
received: RCS_, RUS_, RAS_, PACRCS_, PACRUS_, or
PACRAS_.
Packed Configuration
Status
Configuration Status:
Confirmation:
Where:
aa = # of 0.25 dB steps in Hex above 0dB (0 to 120)
b = 1 = Amplifier is On; 0 = Off
c = 1 = TX On; 0 = Off
d = 1 = unit ONLINE; 0 = OFFLINE
e = 1 = Redundancy On; 0 = Redundancy Off
ff = KPA No. = BU = 01 or 02 ( e = 0, ff = 00)
g = A = Auto Mode; M = Manual Mode
h = 1 = Auto Recovery enabled; 0 if disabled
