- 3G/GSM cellular connectivity with internal antennas for remote reporting
- Built-in accelerometer for motion detection and crash or sudden movement events
- RS232/RS485 data interface to connect third party external devices and sensors
- Built-in features for driving monitoring such as green driving, overspeed, and excessive idling detection
Core Features of Teltonika - FMU125
- GNSS based real-time tracking for location acquisition and route history
- 3G/GSM connectivity with internal antennas for consistent reporting
- Integrated accelerometer to support movement, crash, and towing detection
- RS232 and RS485 interfaces for third party device integration and telemetry
- Driving behaviour monitoring features including green driving and overspeed detection
- Excessive idling detection and GNSS fuel counter functionality
- Immobilizer support and iButton read notification for security and access events
- Geofence capabilities including automatic geofence handling and manual geofence creation
How These Features Work with Plaspy
Plaspy receives position and event data from compatible FMU125 units and presents that information in dashboards, maps, and event streams so teams can act on location and status in near real time.
- Live vehicle position and route playback shown on Plaspy maps
- Motion and accelerometer events (for crash, towing, or sudden movement) appear as alerts and timeline entries
- Driving behaviour events such as overspeed, excessive idling, and green driving scores are available for reporting and operational review
- External device data sent via the RS232/RS485 interface can be included in device reports and event logs where the data format is supported
- Geofence entries and exits, whether automatic or manually defined, generate notifications and history records inside Plaspy
Typical Use Cases
- Fleet management and route oversight with continuous location updates
- Car rental and vehicle access monitoring using immobilizer and iButton events
- Taxi and public transport tracking for live location and service monitoring
- Logistics and delivery operations with geofence and overspeed alerts
- Asset protection and theft detection with unplug, towing, and crash notifications
- Driver behaviour programs using green driving and idling reports
Feature Availability Notes
- Feature availability depends on the device firmware level and the firmware features enabled by the manufacturer
- Hardware revisions and regional cellular variants can affect GNSS and mobile network behavior
- Some functions require correct installation and wiring to external sensors or accessories to surface in platform reports
- Third party device integration via RS232 or RS485 may require specific configuration or protocol support on both the device and the platform side
- Always consult device release notes and installation guides for the exact behavior of a given unit
