3.3.1.4 Reference Priorities: EXAMPLES
Example 1 – GNSS as primary reference, IRIG as backup:
In this use case, the objective is to use:
GNSS as the primary Time, and 1PPS reference
IRIG as the backup Time, and 1PPS reference.
Step-by-step procedure:
1.
Move the reference which has “GPS 0” in the Time column and “GPS 0” in the
1PPS column to the top of the table, with a Priority value of 1. Click the Enabled
checkbox.
2.
Move the reference which has “GPS 0” in the Time column and “GPS 0” in the
1PPS column to the top of the table, with a Priority value of 1. Click the Enabled
checkbox.
3.
Move the reference which has “GPS 0” in the Time column and “GPS 0” in the
1PPS column to the top of the table, with a Priority value of 1. Click the Enabled
checkbox.
Since both of these references are
default
references, no additional references need to be
added to the Reference Priority table.
Example 2 – IRIG as primary reference, NTP input as backup
In this use case, the objective is to use:
IRIG as the primary reference input
Another NTP server as backup reference
Step-by-step procedure:
1.
Move the reference which has “IRIG 0” in both the Time column and “IRIG 0” in the
1PPS column to the top of the table, with a Priority value of 1. Click the Enabled
checkbox.
2.
Move the reference which has “NTP” in the Time column and “NTP” in the 1PPS
column to the second place in the table, with a Priority value of 2. Click the
Enabled checkbox.
3.
For all other references, uncheck the Enabled checkbox, so that they are all dis-
abled.
Since both of these references are
default
references, no additional references need to be
added to the Reference Priority table.
