Network Time Protocol (NTP) Service
The TruVision Navigator Server has the ability to act as an NTP Service for devices on
the network (you also have the flexibility to use other 3rd party NTP Services should you
choose).
Enable the NTP Service in TruVision Navigator by going to Start – All Programs –
TruVision Navigator – Enable NTP Service. This will enable the NTP Service on the
TruVision Navigator Server. You will need to configure the device’s NTP Server field
with the IP Address of the TruVision Navigator Server where this NTP Service is
running.

If your system is closed (meaning no Internet access), the devices configured to point to
the TruVision Navigator NTP Service will use that server machine’s CMOS clock. Please
ensure this clock is up to date. If your system is open (meaning it has Internet access),
you can still have the devices point to the TruVision Navigator NTP Service for time sync
AND have the TruVision Navigator NTP Service point externally to a time reference
server to maintain that system time. This alleviates the maintenance of manually
ensuring the time on the TruVision Navigator Server is up to date.
