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

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

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 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 ×
2. 6 mm. Mounting Method: DIN-rail mounting. Reload Button: Long press to restore factory settings. Indicators: POWER, WORK, COM, and CAN. Interface Parameters:. CAN Port Specifications: 1 CAN port; supports CAN FD; compatible with CAN
3. 0A/2.0B. CAN Port Baud Rate: Arbitration phase: 5 Kbps–1 Mbps; Data phase: 100 Kbps–5 Mbps. Termination Resistors: 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. Serial Port Specifications: Supports one RS485 or RS232 connection. Software Functions:. Modbus Gateway: 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). Conversion Direction: Supports bidirectional conversion, serial-to-CAN only, and CAN-to-serial only. Firmware Upgrade: Supports firmware upgrades via host PC software. Parameter Configuration: AT commands or host PC software configuration. Protection Parameters:. ESD Protection: Air discharge 8 kV, contact discharge 6 kV. Electrical Fast Transient (EFT): Power circuit 2 kV; RS485/RS232 circuit 1 kV; CAN circuit 1 kV. Surge immunity test: Power supply circuit—differential mode 1 kV, common mode 2 kV; CAN circuit—common mode 2 kV
