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 OFF;
  • ignition switch is ON and engine OFF (also called: accessory position);
  • ignition switch is ON and engine IDLE.

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

In the configuration then

  • use the ignition source from power voltage and
  • in the low voltage (mV) setup a bit more less than the voltage with running engine.

Then you will always see that Ignition value 1 only then when the engine is running.
