FMB125 Auto Geofence settings

AutoGeofence is based on the last known position after the movement has stopped. You can be notified using this function if your car is taken away. The shape and size of Geofence zones are set by parameters. It is possible to state whether entering or leaving the geofence triggers an asynchronous message. AutoGeofencing options can be configured by following parameters as depicted in the right hand side figure:
Activation timeout defines the delay between the creation of AutoGeofence within set Radius value around vehicle's most recent position and when the ignition is off. Note that AutoGeofencing does not require entering coordinates, instead it requires GPS visibility. Event generation can take place on Geofence Entrance, Exit or On Both. Eventual Records is used to enable or disable Eventual Records functionality. AutoGeofence can be deactivated by:

• Digital Input 1 – If DIN1 voltage becomes equal or higher than 6.9 V.
• iButton – If authorized iButton is attached.
• Power Voltage – If power voltage becomes higher than low voltage level (defined in Ignition settings).
• Engine RPM – If engine RPM value becomes higher than 0.

“Activation Timeout” has a second function. It works together with GNSS fix to indicate if the tracker moves after GNSS fix is los. When the geozone is created, and later these conditions are met:

• GNSS fix is lost;
• Movement is detected by Movement Source;
• Deactivation is not performed by the user;

The tracker starts monitoring GNSS status for the duration of “Activation Timeout”. If GNSS fix is achieved – the timeout pauses and will continue again once all 3 conditions are satisfied. If GNSS fix is not achieved during “Activation Timeout” – the tracker sends an eventual record with AVL ID 175 and value 0 (regardless of if the vehicle moves from or stays in the geozone). This timeout can be reset by triggering “Deactivate by” source, or if movement stops when there is no GNSS fix.
