GNSS Performance & Positioning

The FMB640 supports satellite systems GPS, GLONASS, GALILEO, BEIDOU, SBAS, QZSS, and DGPS via 33/99 acquisition channels. Tracking sensitivity is -165 dBm with a positioning accuracy of under 3 m. Hot start takes less than one second, warm start under 25 seconds, and cold start under 35 seconds. Time synchronization is performed via GNSS, NITZ, or NTP. External high-gain antennas are used for GNSS and GSM.

Interfaces & Connectivity

The device features four digital inputs, four digital outputs, and four analog inputs. Two RS232 interfaces support modes such as Log Mode, NMEA, LLS, LCD, RFID HID/MF7, Garmin FMI, TCP ASCII/Binary, TCP ASCII/Binary (Buffered), Rec to LCD, Atol Tachograph, UL202-2 Fuel Sensor, TSM232 Satellite backup, and Carrier Freezer. One RS485 interface offers modes including Silent, Log Mode, NMEA, LLS, TCP ASCII/Binary, and TCP ASCII/Binary (Buffered). Additionally, two CAN J1939 interfaces, one J1708 interface, one K-line interface, and one 1-Wire port are available. Internal flash memory is 2 MB, expandable via micro-SD cards up to 32 GB. Connectivity is complemented by a USB 2.0 Mini-USB port and two status LEDs.

Fuel Monitoring

The FMB640 supports multiple fuel monitoring methods: analog LLS sensors, digital LLS sensors via RS232 and RS485, LV-CAN200, ALL-CAN300, CAN-CONTROL, and CAN FMS via J1939 and J1708. Additionally, ultrasonic level sensors can be connected. This range of supported methods enables fuel monitoring across various vehicle and machinery types.

Applications

The FMB640 is designed as a GNSS and GSM terminal for professional applications where a single device handles multiple tasks. It is ideal for international logistics, refrigerated transport, agriculture, construction and mining, as well as security and emergency services. The combination of CAN data reading via J1939 and J1708, multiple serial interfaces, and dual-SIM functionality makes it particularly suitable for heavy-duty vehicles and specialized machinery.

Power & Environmental Conditions

The input voltage range spans 10 to 30 V DC and includes overvoltage protection. An internal Ni-MH backup battery with 550 mAh and 8.4 V enables operation without an external power source. Three sleep modes—GPS Sleep, Online Deep Sleep, and Deep Sleep—reduce power consumption during idle periods. The operating temperature without the battery ranges from -40 °C to +85 °C, with the same range for storage. Humidity tolerance is 5 % to 95 % non-condensing, and the device meets IP41 protection standards. Battery storage temperature ranges from -20 °C to +45 °C.

Configuration & Firmware

Configuration and firmware updates are performed via FOTA Web, FOTA, or the Teltonika Configurator. SMS commands support configuration, event handling, DOUT control, and debugging. GPRS commands enable configuration, DOUT control, and debugging. These flexible remote access options simplify fleet management without requiring physical access to the device.
