APPENDIX
Under General Status:
Reference ID : This is the identifier given to the input by SecureSync.
Validity : Indicates the validity of the Time input and the PPS input. If the input signal is
valid the indicator will be green. If the signal is not valid, the indicator will be orange.
Use of Time Fault Discrete : There are two options:
Time Fault Discrete State : If this is valid, the indicator will be green. If it is not valid, the
indicator will be orange.
Use of Bit Synchronization (BS) : There are two options:
Reference Selection : Indicates which TOD signal is used for synchronization. This will be
either TOD 1 or TOD 2.
The incoming input time information may be provided as local time, but System Time may be
configured as UTC time, so internal computations need to be performed. With the Timescale
field set to "Local", select the name of a previously created Local Clock. The Time Zone and DST
rules, as configured in the Local Clock will be applied to the front panel time display. Refer to
for more information on Local Clocks.
Under Time of Day Inputs:
TOD Format : The user-selectable format being used. Available formats include:
428
Enabled : The TFD input signal is used to validate the STANAG input.
Disabled (default): The TFD input signal is ignored.
Enabled : The second STANAG input (TOD 2) is used to receive the BS (Bit
Stream) signal used with STANAG 4430-STM. When BS is active, the con
figuration of TOD2 is superseded and only used for BS.
Disabled : The second STANAG input (TOD 2) can be used to receive an inde
pendent TOD.
