The Teltonika RUT204 is an industrial 4G LTE Cat 4 router with native CAN bus, RS232, GNSS, dual SIM, two Ethernet ports and Wi-Fi 4. It is built for vehicles, machinery and energy equipment where data needs to come straight off the CAN bus and back to a central system.

The defining capability of the RUT204 is direct access to CAN bus data. Instead of adding a separate gateway, the router reads machine data itself, logs it and forwards it to local or cloud servers with its Data to Server tool. GNSS adds location data for fleet and mobile assets, and two SIM slots with automatic switching keep the connection up when a network drops.
