The Web UI list entries for these cards are: 1PPS/Frequency BNC and 1PPS/Frequency RS-
485.
The connector number is: J1 (BNC card); J1 (RS-485 card).
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 "Configuring Input Reference Priorities" on page157 for more information
on reference priorities.
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.
Reference Mode: Displays how the reference mode operates in determining its validity.
Frequency: Displays (in Hertz) the configured frequency of the input frequency signal.
The 1PPS Input signal is analyzed and an absence of the signal triggers a “Not Valid” indic
ation.
