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.
To configure the unit to use a private NTP server:
1. From the System menu, click the NTP submenu.
2. Click the NTP box. The remaining boxes become available.
3. Click the Server box, and select PRIVATE SERVER.
4. To enter the private server’s IP address:
a. Click the Private Time Server box.
b. Enter the private server’s IP address.
c. Click OK.
