Alternatively, you can use Paste Certificate to copy and paste the certificate from the
certreq.jsp
file into this field. Open the
certreq.jsp
file using a text editor (e.g., Notepad)
and copy the contents. The certificate should be base 64 encoded. Paste the contents in the
Paste Certificate field here, then click
Submit.
The S100 is self-signed, thus it can verify your certificate.
For more about how the S100 uses NTP keys and certificates, see

This section of the interface lets you view various aspects of the Symmetricom bc635/637
PCI board—the timing engine of the S100.
Main Settings
The timing engine mode choices you see in the drop-down list box are:
• GPS is the default, which obtains the time from GPS receiver and antenna.
• IRIG, which obtains the time from the IRIG time code input. (Note: IRIG time code
doesn’t include the year with its time information. Be sure to enter the year in the Year
field.)
• Free Running means there is no external timing source used, that the time is set
manually
• One Pulse Per Second, or 1PPS, syncs the oscillator to a user-supplied 1PPS
