FMB641 - Leading GNSS/GSM Terminal for Professional Applications

The Teltonika FMB641 is an updated version of the popular GNSS/GSM terminal for professional applications, the FMB640. Compared to the FMB640, the FMB641 features a new processor that enhances the device's computational power, allowing it to be tailored to more specific use cases. Switchable CAN terminators enable the device to be used in a CAN network with multiple nodes. Additionally, it can be powered via USB for easier configuration. All features supported by the FMB640 are also available in the FMB641, maximizing fleet efficiency with capabilities such as FMS CAN data (J1939), fuel CAN data (J1708), tachograph live data (K-Line), remote tachograph file download, support for various third-party RS232 or RS485 devices, and dual-SIM or eSIM compatibility. The terminal is suitable for applications including international logistics, refrigerated transport, agriculture, construction, mining, security, emergency services, and more.
