The Network Ports can be configured under MANAGEMENT > Network Setup . For more
information, see "Configuring Network Settings" on page 54.

2.17.5 Signature Control

Signature Control is a user-set parameter that controls when a SecureSync output (for example,
1PPS, or IRIG) will be present. This feature allows you to determine how closely you want to link
an output to its input. This not only allows you to determine the quality of your output signal
(e.g., by deactivating it, when the holdover period expires), but also offers the capability to
indirectly send an input-reference-lost-alarm to a downstream recipient via the presence of the
signal.
E X A M P L E S :
You can setup Signature Control such that SecureSync's built in 1PPS output becomes disabled the
moment its input reference is lost (e.g., if a valid GNSS signal is lost).
Or, you can setup your output signal such that remains valid while SecureSync in holdover mode, but
not in free run.
The available options are:
I.
Output Always Enabled —The output is present, even if SecureSync is not synchronized
to its references (SecureSync is free running).
