FMB641 – Leading GNSS/GSM Terminal for Professional Applications

Teltonika FMB641 is an updated version of the currently most popular GNSS, GSM terminal for professional applications FMB640. Compared to FMB640, FMB641 has a new processor that improves the devices computation power. Therefore it can be tailored to more specific use cases. Switchable CAN terminators will allow you to use the device in a CAN network with numerous nodes. Lastly, it can be powered via USB for an easier configuration process. All the features that are supported by FMB640 are also supported by FMB641, for the purpose of maximizing your fleet efficiency with features like FMS CAN data (J1939), fuel CAN data (J1708), tachograph live data (K-Line), remote tachograph file download, various third party RS232 or RS485 devices support and dual-SIM or eSIM compatibility. The terminal is suitable for applications like international logistics, refrigerated transport, agriculture, construction & mining, security & emergency services and even more.
