immobilize vehicle leaving geofence

It is possible to do this using Codec12 Protocol, that is designed for the FM device and server communication.

For example:

Configure Auto-Geofence on High Priority
Eventual Records -> Enable
Generate Event -> On Exit
Deactivate by -> iButton or Digital Input 2/ Digital Input 3 and connect an additional button for Authorized Driving, would only need to send Voltage higher than 2.5 V to DIN2/DIN3
if Vehicle is being stolen and leaves the Auto-Geofence, an event is generated that the vehicle left the Zone, with Event I/O ID 175 ()
Server parses the Record and if it finds the Event I/O ID 175 sends GPRS command:
00000000000000140C01050000000C7365746469676F757420313F010000DED1

This will set DOUT1 to High for Infinite time.
