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

  1. Send SMS command about opening the doors;
  2. FM device receives SMS command;
  3. FM device sends request to the CAN-CONTROL adapter;
  4. 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


Time zone configuration

It is recommends to you use NITZ+NTP time synchronization, because firstly device will try to get time from NITZ (Mobile operator which you are connected) so you should have time  (GMT+1) depending where you are in the world and if the device will switch to NTP, there is (GMT+0).  

  • You can configure your device NTP server which is local on your country to have a valid time and set time resync 1 hour. Device will update your device time every hour.


GPS issue

-If you have a problem with gps connection please change  the movement start delay to 10s by SMS/GPRS commands:

setparam 19001:10


.Bin file

Q: How to parse .bin file?

A: .bin file should be added to TAVL server to get records parsed.  Device should be added as object to TAVL server.
