How to Detect Accessory/Quadro State Using Teltonika Device Parameters?

TELEMATICS
1

I am working on a GPS tracking application using a Teltonika device (FMBXXX series). I need to determine the Accessory/Quadro state of a vehicle based on the data received from the device.

Currently, I have access to the following parameters:

  • 239 - Ignition Status (0 for Off, 1 for On).
  • 240 - Movement Status (0 for Not Moving, 1 for Moving).
  • 66 - External Voltage (in volts, with values like ~12.0V for Off and ~13.8V for On).

I can differentiate between Ignition Off and Ignition On states using parameter 239. However, I need guidance on how to identify when the vehicle is in the Accessory/Quadro state, which occurs when the key is turned but the ignition is not fully on (engine not running).

Questions:

  1. Are there specific thresholds or combinations of parameters (e.g., 66 External Voltage or others) that can reliably indicate the Accessory/Quadro state?
  2. Does Teltonika provide additional I/O elements or configurations that can help detect this state?
  3. Can I use any custom configurations or event triggers within the Teltonika device to identify this state more precisely?

Thank you for your assistance! Any guidance or recommendations would be greatly appreciated.

Hello
Good day!

I suggest you to use a CAN adapter along with FMBXX, this device will give you the engine information (RPM, Temp, statute, etc…),
the Din (ID240) is dedicated to the Ignition, not to the engine, however, you can use as an alternative way to the CAN Adapter (but it is not accurate) the ID 66 (External Voltage), as when the engine is running, the vehicle dynamo will work to charge the battery, and this will rais the voltage to be >13V, normally the voltage if the engine is off will be similar to the battery voltage (in range of 12V)
