NTP
The unit’s internal time can be synchronized with an external time source using the Network Time Protocol (NTP) configuration option.
The unit allows you to configure the following settings:
• NTP: When selected, allows you to configure a NTP server to which the HVR’s internal time is synchronized.
NOTE: If the NTP option is set to ON, the Date/Time option is unavailable.
• Server: Allows you to select a public or private NTP server. The default setting is PUBLIC SERVER. If you select a public NTP server, the
HVR computes the average time from five public servers: time.nist.gov, time-a.nist.gov, timeb. nist.gov, ntp.nasa.gov, and clock.isc.org.
• Private Time Server: Allows you to enter the IP address of a private NTP server. The server must be set to PRIVATE SERVER before you
can enter an IP address.
• Sync. interval: Specifies how often the HVR synchronizes with the NTP server: daily (1 DAY), weekly (1 WEEK), monthly (1 MONTH), or
hourly (1 HOUR). The default setting is 1 DAY.
• NTP Test: Verifies network access to the NTP server.
