Vanguard 3000 Multicarrier Cellular Data Modem & IP Router PN 134732-VG3000 Rev. D| Page 22
Network Time
The Vanguard 3000 is capable of maintaining the current time (UTC) by synchronizing itself with a Network Time
Protocol (NTP) Server. You may specify a server domain name or IP address and how frequently the router should
synchronize with the server. The router must have DNS access and a route to the internet to synchronize with the
supplied default ntp.org server – this is not always true on private cellular networks. The router does not save or track
time while powered off, so time will be inaccurate until the router can connect with the server, which it does on
startup (in addition to synchronizing according the Update Frequency specified).
NTP Client
Disabled by default. Select Enable to activate the router’s NTP client to synchronize with the specified server.
NTP Server
Enter the domain name or IP address of the desired NTP Server. Most public NTP Servers have a posted usage
policy. A review of usage policies and the choice of an appropriate server is recommended.
Update Interval
Specify the frequency to synchronize the router time with the configured NTP Server. By default,
synchronization is set 24 hour.

CARRIER
The Carrier tab enables you to configure the carrier (cellular provider) and credentials to be used for data calls. Two
carriers can be configured and either of them chosen to be the active carrier, or you can set parameters for automatic
carrier switching. Depending on the carrier(s) selected, more settings and actions are available in the Settings tab.
