Waveshare CAN FD Protocol Converter CAN FD To ETH/RS232/RS485 Bidirectional Data Communication

1. The CAN FD ETH RS232/RS485 Converter is a DIN-rail mountable device designed for bidirectional conversion between CAN FD and Ethernet/RS485/RS232 interfaces. It features high speed, low latency, stable performance, ease of use, and excellent cost-effectiveness. Supporting five data conversion modes—Transparent, Transparent with ID, Standard Protocol, Modbus, and Custom Frame Header/Footer—it enables interconnection between CAN networks and Ethernet or serial devices and is compatible with CAN FD and CAN 2.0A/2.0B protocols.
2. Built with an industrial-grade design, the device operates reliably within a temperature range of -40C to 85C and supports a wide power input range of 9V to 36V. It accommodates baud rates of 5 Kbps to 1 Mbps for the arbitration field and 100 Kbps to 5 Mbps for the data field.
3. The device supports configuration via host-side software and features a built-in 120Ω bus resistor (selectable via DIP switch) and DIN-rail mounting capability, ensuring convenient and efficient setup and installation. Basic
