Position - GPS support

Certain Digi devices have native GPS support with a geofence application. There are two groups of

position settings. Static position settings define the latitude and longitude coordinates for the Digi

device. GPS geofence settings define perimeters around a point such that moving into, out of, or

being outside of the perimeter will be reported to the Digi device’s event log, an SNMP server, or

reported via e-mail. A supported GPS receiver must be configured for use by the device.

A GPS drive allows GPS data to be read from devices providing an NMEA-0183-compliant serial

stream via serial or USB. Data can be used by Python, the web interface, command line,Device

Cloud, and the geofencing application.

Static Position Settings

The static position settings define latitude and longitude coordinates for the Digi device. These

parameters can be queried with the RCI protocol, and this information can be used by applications

such as Device Manager.

 Latitude: The static latitude of the device, in degrees (-90.0 - 90.0).

 Longitude: The static longitude of the device, in degrees (-180.0 - 180.0).

Geofence Settings

Up to 16 geofences can be defined. To add a geofence, click the Add button. The configuration

settings for the geofence are displayed.

General Settings

 Name: A name to reference this geofence. This name will appear in the event log,

SNMP trap, and/or e-mail report.

 Latitude: Latitude of the center of the geofence, in degrees (-90.0 - 90.0).

 Longitude: Longitude of the center of the geofence, in degrees (-180.0 - 180.0).

 Maximum HDOP: This is the maximum tolerated horizontal dilution of precision that

is allowed for reporting a geofence event. When the reported HDOP is greater than this

value, fence event log reports, SNMP traps, and e-mail reports will not be sent. HDOP

tolerances vary by receiver.

 Entry Radius: The entry radius, in meters, is the distance from the center of the fence

for entry. That is, if the device is less than this distance from the defined center, an entry

event has occurred.

 Exit Radius: The exit radius, in meters, is the distance from the center of the fence for

exit. That is, if the device is more than this distance from the defined center, an exit

event has occurred. This is also the distance used to determine if the device is outside of

the fence for update events.

 Location Update Interval: The location update interval, in seconds, specifies the

amount of time to wait between reporting that the device is outside of the geofence. This

applies to event log, SNMP, and e-mail reports.
