Configuring Input Reference Priorities

SecureSync can use numerous external time sources, referred to as "references".
As external time sources may be subject to different degrees of accuracy and reli-
ability, you can determine in which order (= priority) SecureSync calls upon its
external time and 1PPS references.

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.
