The "Speeding" section of the Dart system parameters allows a maximum speed Threshold (km/h) to be stored on the device. If the Threshold speed is set, the device will sound a buzzer output when the GPS speed exceeds the Threshold. The buzzer will remain active until the GPS speed drops by the Delta (km/h) value below the Threshold. 


  • This has no effect on logging. Speed violation notifications should still be setup on the software platform. This is designed to control driver speed with buzzer feedback.
  • An output must be setup as a buzzer on the device. The output (yellow) provides the ground to the buzzer. 

Example: The customer wants a buzzer to sound when 100 km/h is breach and to turn off when the speed drops 5km/h under this amount once breached.

Threshold = 100km/h
Delta = 5km/h
Output 1 Function = Buzzer

How you would setup this example on the Speeding tab and the buzzer output on the Digital Output 1 tab;
