How It Works with Plaspy
The BN-403D integrates with Plaspy using industry-standard transport protocols to deliver continuous location and telemetry into the Plaspy platform. Position fixes, status updates and alarm events are forwarded over TCP, UDP or SMS so Plaspy dashboards and mobile apps receive timely information for real-time tracking, geofence enforcement and historical playback. Configuration commands can be issued remotely or via Bluetooth for on‑vehicle setup.
- Real-time location and telemetry updates transmitted to Plaspy for live tracking and route playback.
- Ignition (ACC), door and alarm status reporting for anti-theft and operational monitoring.
- Optional fuel monitoring: remaining fuel queries and fuel detection alarms when paired with the supported fuel sensor.
- Remote power cut control via the included relay—commonly used to disable vehicle power safely from Plaspy when required.
- Bluetooth configuration for quick setup and automatic induction arming/disarming; compatible with in-vehicle accessories and easy commissioning.
