Powered digital matter devices have a 'onboard speeding' parameter which 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.

Notes:
- 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.
- See notes here about Buzzing - Common Concepts - Buzzer/LED Setup
- When parameters are set to buzz - such as buzzing on over speed and buzz on no driver ID - in firmware this tells the following outputs to buzz
- The buzzer on the PCB for the G100 and G120
- The internal buzzer in the RFID driver ID reader if connected
- Any outputs set to 'buzz'
- So if you are already using the RFID reader - there is no need to wire any additional buzzers!
- When parameters are set to buzz - such as buzzing on over speed and buzz on no driver ID - in firmware this tells the following outputs to buzz
| Device | Firmware |
|---|---|
| Dart2 | 1.8 |
| G62 | 1.1 |
| G100 | 1.7 |
| G120 | 2.1 |
| G200 | 2.0 |
Example: If 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. Your settings would be the following:
- Threshold = 100km/h
- Delta = 5km/h
- Output 1 Function = Buzzer (if RFID reader isn't in use)
