Power Management
 ID
This identification number serves to distinguish this unit from other units in the network. It is at the same time the
TAIP identification for GPS reporting and serves as the 'syslocation' for the SNMP facility.
Power Management
The Vanguard 3000 unit is designed to stay ON even if the ignition is turned off. The unit can be configured to automatically
shut down 1, 5, 30, 60 or 240 minutes after ignition has been turned off or when the supply voltage drops to a certain level.
 Shutdown Method
Disabled by default. Select "Power off" to enable power management.
 After Ignition Line Off
Select between the following time intervals: 1, 5, 30, 60 or 240 minutes.
 When Voltage Drops Below
Enter desired voltage. Enter "0" to disable (and give precedence to time delay configured under "After ignition
time off").
Network Time
The Vanguard 3000 is capable of maintaining the current time (UTC) by synchronizing itself with a Network Time Protocol
(NTP) Server. The user may specify a server URL and how frequently the router should synchronize with the server. The
router must have an internet connection to synchronize with the server. The router does not save/track time while
powered off, so time will be inaccurate until the router can connect with the server.
 NTP Client
Disabled by default. Select Enabled to activate the router’s NTP client to synchronize with the specified server.
 NTP Server
Enter the URL of the desired NTP Server. Most NTP Servers have a posted usage policy. A review usage policies
and the choice of an appropriate server is recommended.
 Update Frequency
Set to 24 hours by default. Specify the frequency to synchronize the router time with the specified NTP Server.
