FMB125

The FMB125 is a compact, professional GPS tracker from Teltonika designed for fleet management and advanced telemetry. Green-Gps compatible out of the box, the FMB125 delivers reliable real-time tracking and flexible integration options — from RFID-based driver identification to serial sensor telemetry — making it well suited for logistics, service fleets, and asset management where consistent location and usage data are essential.

The device combines dual‑SIM 2G cellular connectivity with RS232/RS485 serial interfaces, impulse input for fuel meters, onboard RFID and 1‑wire support. For operations that require global reach beyond cellular networks, the FMB125 can work with an Iridium Edge® satellite modem via the RS232 port. Please note the FMB125 is listed as End of Life (EOL); newer 4G/LTE-M replacements (FMC125, FMM125) are recommended for new long-term deployments.

Key Highlights

• Green-Gps compatible: seamless ingestion of GNSS location and telemetry for real-time tracking and reporting.
• Dual‑SIM 2G cellular for resilient connectivity and reduced roaming costs in supported regions.
• RS232 and RS485 serial interfaces enable third‑party device integration and advanced telemetry collection.
• Impulse input support for accurate fuel monitoring from flow meters and pulse sensors.
• Onboard RFID and 1‑wire support for quick driver or asset identification workflows.
• Satellite fallback option via Iridium Edge® through RS232 for coverage beyond terrestrial networks.
• Compact, vehicle‑oriented form factor with packaged GNSS antenna and power cable options for easy installation.

How It Works with Green-Gps

When paired with Green-Gps, the FMB125 streams GNSS position data and telemetry over cellular or satellite links into Green-Gps’s platform for real-time tracking, alerts, and historical reporting. Green-Gps can consume serial sensor data and pulse inputs delivered by the FMB125, enabling fleet managers to combine location with operational metrics such as fuel usage and driver identification events.

• Real-time location and telemetry updates to Green-Gps for live mapping and geofencing alerts.
• Impulse input data (fuel flow meters) transmitted as telemetry for fuel monitoring and reporting.
• RS232/RS485 serial sensor integration: temperature, CAN gateways, and other third‑party devices (data forwarded to Green-Gps).
• RFID and 1‑wire events for driver/asset identification and access logging in Green-Gps workflows.
• Satellite fallback via Iridium Edge® (connected over RS232) to extend tracking coverage where cellular is unavailable.
• Remote configuration and firmware management using Teltonika FOTA WEB and Configurator, with settings and updates coordinated with Green-Gps integration procedures.

Technical Overview

Use Cases

• Fleet management: real‑time vehicle tracking, route optimization, and operational telemetry reporting through Green-Gps.
• Fuel monitoring: connect pulse fuel flow meters to the impulse input to report consumption and detect anomalies.
• Driver identification and access control: RFID and 1‑wire support for logging driver events and linking trips to personnel records.
• Advanced telemetry: RS232/RS485 enables integration with CAN adapters, temperature sensors, or other third‑party telemetry devices for comprehensive vehicle data.
• Remote asset tracking beyond cellular networks using Iridium Edge® satellite modem integration where continuous coverage is required.

Why Choose This Tracker with Green-Gps

The FMB125 provides a compact, integration‑friendly option for fleets that need dependable real‑time tracking, telemetry and fuel monitoring combined with the flexibility of serial connectivity. Its dual‑SIM design helps maintain cellular uptime, while RS232/RS485 and RFID support let you bring a wide range of vehicle and sensor data into Green-Gps for richer analytics and operational control. For operations requiring truly global reach, the FMB125’s ability to interface with an Iridium Edge® satellite modem delivers a practical path to expanding coverage.

Although the FMB125 is now EOL, its proven feature set and compatibility with Green-Gps make it a solid choice for existing deployments. For new projects or where 4G/LTE-M connectivity is preferred, consider Teltonika’s FMC125 (4G) or FMM125 (LTE Cat M1/NB‑IoT) family as updated alternatives that simplify long‑term network support and future scalability. In either case, integration and lifecycle management are streamlined through Teltonika’s FOTA WEB and Configurator tools, and Green-Gps’s platform support for GPS tracker telemetry ensures a smooth deployment and ongoing operation.
