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.

close doors

Send SMS command about opening the doors;
FM device receives SMS command;
FM device sends request to the CAN-CONTROL adapter;
CAN-CONTROL adapter sends request to the vehicle computer about opening the doors.

counting running engine hours

We would recommend to measure the power voltage when ignition switch is ON and:

engine OFF (Vacc);
engine IDLE (Vidle).

A running engine implies higher power voltages than an engine switched off.

In the configuration then

use ignition source from power voltage;
set low voltage (mV) halfway between Vacc and Vidle.

Then you will get ignition value = 1 only when the engine is running.

Example:

Vacc = 25 V
Vidle = 27.5 V
=> low voltage = 2,600 mV

Geofence using sms

Q: How to activate geofencing notifications using SMS?

A: In this case You should simply create the recipient specifying required GSM number and then while creating new Geofencing rule (or editing current rule) add as a recipient Your created recipient that uses GSM number
