Overview

FMC650 is a leading GNSS/LTE/GSM/BLE terminal built for advanced fleet applications. It combines 4G LTE Cat 1 connectivity with 2G fallback, dual-channel L1+L5 GNSS positioning, and an extensive interface set — including RS232, RS485, dual CAN (J1939/J1708) and K-Line — for reading tachograph and heavy-vehicle data. Dual-SIM support and a Bluetooth 5.0 LE radio round out a device designed for trucks, buses and other professional fleets.
