USR-DR404 - Industrial CAN to Ethernet & WiFi Converter

The USR-DR404 is an industrial-grade network converter designed to bridge CAN, RS485, Ethernet, and WiFi networks, enabling seamless data communication among multiple industrial protocols. With two CAN ports, one Ethernet port, and WiFi support, it allows flexible integration of legacy CAN and RS485 devices into modern TCP/IP networks, extending your industrial network with high reliability.

The DR404 supports transparent data transmission between CAN, Ethernet, and RS485 networks, as well as protocol conversion between Modbus RTU and Modbus TCP. Its rugged industrial design, wide voltage range, and extended operating temperature make it suitable for harsh environments and continuous operation. Configuration is simple via web server interface or AT commands, and the device can support custom applications for specialized industrial use cases.
