1PPS Input: Status Window
To view the current settings of the PPS Input (also referred to as ‘Reference’), go to its Status win
dow. For instructions, see: "Viewing Input/Output Configuration Settings" on page329.
The Web UI list entries for these cards are:
1PPS In/Out
1PPS In/Out, Fiber
The connector number for the input is: J1
Note: SecureSync starts numbering I/O ports with 0 (only 1PPS and 10MHz out
puts start at1, because of the built-in outputs).
The Status window displays the following settings:
Reference ID: Name used to represent this 1PPS input reference in the Reference Priority
table. See also: "Configuring Input Reference Priorities" on page157.
1PPS Validity: Indicates “OK” (green) if the 1PPS input signal is present and valid. Indic
ates “Not Valid” (orange) if the 1PPS input signal is either not present or is not con
sidered valid.
Edge: Displays the selected Edge (rising of falling) of the 1PPS input that defines the on-
time point.
Offset: Displays the configured 1PPS offset values.
The 1PPS Input signal is analyzed and an absence of the signal triggers a “Not Valid” indic
ation.
