usage scenario
immobilizer
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
