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

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

1. 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 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. 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.

3. 0A/2.0B. CAN Baud Rate: Arbitration phase: 5 Kbps–1 Mbps; Data phase: 100 Kbps–5 Mbps. Termination Resistor: Two built-in 120Ω resistors; setting either DIP switch to ON connects one 120Ω resistor in parallel; setting both to ON connects two 120Ω resistors in parallel. Ethernet Port: RJ45, 10/100 Mbps, auto-MDI/MDIX. Serial Port: Supports one RS485 or RS232 connection. Software Functions:. Modbus Gateway: Ethernet: CAN (FD) to Modbus TCP (Master/Slave); Serial: CAN (FD) to Modbus RTU (Master/Slave). Transmit Messages: Supports configuration of up to 64 transmit messages. Receive Messages: Supports configuration of up to 64 receive messages. Conversion Modes: Transparent conversion, transparent conversion with ID, standard conversion, Modbus conversion, and custom frame header/footer conversion. CAN ID: Supports standard frames and extended frames. Frame ID Filtering: Supports standard frames only, extended frames only, and custom input frame IDs (up to 32 groups). Packetization (Frame Count/Time): Supports custom frame count and custom time interval for packetization (Ethernet port). Conversion Direction: Supports bidirectional conversion, Serial/Ethernet to CAN only, or CAN to Serial/Ethernet only. Firmware Upgrade: Supports firmware upgrades via host software. Parameter Configuration: AT commands Configuration via commands and host-side software. Other functions: Supports heartbeat packets and registration packets; operating modes include normal, loopback, and listen-only (for the Ethernet port). Protection parameters:.
