Example 4 – Time set manually by the User. Other references may or may
not be available
Note:
In order for a manually set time to be considered valid and used to syn-
chronize VelaSync, a “User” needs to be created and enabled in the Refer-
ence Priority table.
"The "User/User" Reference" on page 116
In this use case, the objective is to use a hand-set time, in combination with VelaSync's oscil-
lator as a 1PPS source as valid references.
Step-by-step procedure:
1.
If necessary (see NOTE above), create a “User.”
2.
Move the reference which has “User 0” in the
Time
column and “User 0” in the
1PPS
column to the top of the table, with a
Priority
value of 1. Click the
Enabled
checkbox.
3.
For all other references, uncheck the
Enabled
checkbox, so that they are all dis-
abled.
If the objective is to use a manually set time as a
backup
to other references (such as
GNSS or IRIG):
1.
Move the "User/User" reference to a place in the table that has a priority lower than
the references the "User/User" reference will be backing up. Make sure the
Enabled
checkbox is selected.
2.
With “User/User” enabled, if no other higher priority references are enabled or avail-
able (or if the higher priority references have since been lost), you can now manually
set the
System
time to the desired value (
MANAGEMENT > OTHER: Time Man-
agement > System Time > Manual Time Set
for more information. VelaSync will go into synchronization using this set time once
you click the Submit button.
Note:
You will need to repeat this procedure each time VelaSync is power-
cycled (with no other references available), unless you enabled the feature
Synchronize to Battery Backed Time on Startup.
Example 5—Time at power-up ("Local System Time") to be considered
"Valid". GNSS input to serve as 1PPS reference
The objective of this use case is to allow VelaSync to use itself as a valid reference. This is
