FAQ Answer
Support Context
This FAQ is sourced directly from our support database. It helps teams deploy GPSController faster, reduce onboarding friction, and understand platform compatibility for real-world fleet operations.
Answer summary
The emergency button needs a clean, debounced digital input to a dedicated GPIO pin—usually a ground pulse. The VTU firmware must be explicitly configured to recognize this as the emergency trigger. Proper debouncing is critical to prevent...
