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

Overview & Features

. The CAN FD to RS232/RS485 converter is a DIN-rail mountable device designed for bidirectional data conversion between CAN FD and RS232/RS485 interfaces. It features high speed, low latency, stable performance, ease of use, and cost-effectiveness. It supports five data conversion modes—Transparent, Transparent with ID, Standard Protocol, Modbus, and Custom Frame Header/Footer—enabling interconnection between CAN and serial devices, while remaining compatible with CAN FD and CAN 2.0A/2.0B protocols. Built with an industrial-grade design, the device operates reliably within a temperature range of -40C to 85C and supports a wide input voltage 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. The device supports configuration via host software and features a built-in 120Ω bus resistor (selectable via DIP switch). Designed for DIN-rail mounting, it offers convenient configuration and efficient installation... Basic Parameters:. Operating Voltage: DC 9V–36V. Dimensions: 110 × 27 × 85.6 mm.
