table are defined as follows:
Priority
—Defines the order or priority for each index (row). The range is 1 to 16,
with 1 being the highest priority and 16 being the lowest priority. The highest pri-
ority reference that is available and valid is the reference that is selected.
Time
—The reference selected to provide the necessary “Time” reference.
1PPS
—The reference selected to provide the necessary “1PPS” reference.
Enabled
—The reference is enabled.
Delete
—Removes the Index (row) from the Reference Priority table.
3.3.1.1
Configuring Input Reference Priorities
VelaSync can use numerous external time sources, referred to as "references". As
external time sources may be subject to different degrees of accuracy and reliability,
you can determine in which order (= priority) VelaSync calls upon its external time and
1PPS references.
