4.2.1.1.4.3 Stored/Faults – TX Interface
DISPLAY SELECTIONS/DESCRIPTION
TX INTERFACE 0
NO FAULT
Note: “-” indicates status of parameter is OK.
“+” indicates a fault.
Reverse contrast “+” indicates an
alarm.
TX CLK PLL
--▓----
Transmitter phase-locked loop fault. Indicates
the transmitter Phase-Locked Loop (PLL) is
not locked
CONFIGURATION
------▓
Tx interface configuration fault.
Indicates the Tx interface cannot execute a
programmed configuration parameter
4.2.1.1.4.4 Stored/Faults – RX Interface
DISPLAY SELECTIONS/DESCRIPTION
RX INTERFACE 0
NO FAULT
Note: “-” indicates status of parameter is OK.
“+” indicates a fault.
Reverse contrast “+” indicates an
alarm..
RX DATA/AIS
--▓-----------
Data or AIS. When data fault is selected in
the Configuration Interface menu (4.2.1.1.1),
the fault indicates a data stable condition.
This indicates the data coming from the
satellite is all 1s or 0s (i.e., data is not
transitioning). When AIS is selected, the
Alarm indicates the data is all 1s from the
satellite. When None is selected in the
Configuration Interface menu, the RX
Data/AIS Fault/Alarm is not activated.
Note: AIS is an alarm, not a switching fault.
BUFFER CLK PLL
-----▓--------
Buffer clock phase-locked loop fault. Indicates
the buffer clock PLL is not locked
CONFIGURATION
-------------▓
Configuration alarm
