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.

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
