The Waveshare CAN FD Protocol Converter is an industrial DIN-rail module enabling bidirectional data translation between CAN FD/CAN 2.0 networks and Ethernet (TCP/IP), RS232, or RS485 interfaces. It supports high-speed data rates up to 5 Mbps and is designed for integration into industrial automation, EV/BMS, and control systems.

Features

  • Bidirectional CAN FD (up to 5 Mbps) to Ethernet (10/100M), RS232, and RS485 conversion.
  • Industrial-grade operation from -40°C to +85°C with wide 9-36V DC input voltage range.
  • Supports multiple conversion modes: transparent, Modbus TCP/RTU, and user-defined protocols.
  • Built-in 120Ω CAN termination resistors with DIP switch control for bus configuration.
  • Robust EMC protection with ESD, EFT, and surge protection on all communication ports.

Description

This converter serves as a critical gateway in industrial networks, translating data between the high-speed, robust CAN FD bus and common industrial serial/Ethernet standards. It maintains full backward compatibility with legacy CAN 2.0A/B networks, ensuring seamless integration into existing control architectures. The device handles protocol conversion with low latency, supporting transparent bridging, Modbus TCP/RTU master/slave modes, and custom protocol mapping for specialized applications.

Engineered for harsh environments, the module features a metal housing, DIN-rail mounting, and comprehensive electromagnetic compatibility (EMC) protection on all signal and power lines. Configuration and firmware updates are managed via dedicated PC software or AT commands over a serial connection, providing flexibility for system setup and maintenance.

Key Features

  • Industrial DIN-rail mount design with metal housing for durability.
  • Wide operating voltage range (DC 9V – 36V) suitable for vehicle and industrial power systems.
  • High-speed CAN FD support with data rates configurable from 100 kbps to 5 Mbps.
  • Integrated 10/100M Ethernet port with auto MDI/MDIX and support for TCP/UDP client/server modes.
  • Configurable RS232/RS485 serial port for legacy PLC and SCADA system integration.
  • Advanced frame filtering supporting up to 32 groups for efficient network traffic management.
  • Comprehensive EMC protection: ±8kV air/±6kV contact ESD, 2kV power/1kV signal line EFT.
  • Firmware upgradeable via host PC for future feature enhancements and compatibility.

Applications

  • Gateway for integrating CAN FD-based Electric Vehicle (EV) Battery Management Systems (BMS) with factory-floor Ethernet SCADA networks.
  • Protocol conversion in industrial automation for connecting CANopen or J1939 machinery to Modbus TCP/RTU controlled PLCs and HMIs.
  • Data acquisition bridge in traffic control systems, linking roadside CAN sensor networks (e.g., vehicle detection) to central RS485 or Ethernet-based control units.
  • Retrofitting legacy manufacturing lines by enabling modern CAN FD controllers to communicate with older RS232/RS485 controlled actuators and sensors.
  • Condition monitoring in renewable energy installations, converting CAN data from wind turbine or solar inverter controllers for remote Ethernet-based monitoring.

Frequently Asked Questions

What is the difference between the transparent and Modbus conversion modes?

In transparent mode, the converter acts as a simple bridge, forwarding raw CAN frames to the selected serial or Ethernet port without protocol translation. In Modbus mode, it actively maps specific CAN message IDs and data to Modbus TCP (over Ethernet) or Modbus RTU (over RS485/RS232) registers, allowing a Modbus master (like a PLC or SCADA) to read from and write to devices on the CAN bus.

How do I configure the built-in 120Ω CAN termination resistor?

The termination resistor is controlled by a DIP switch located on the device. You should enable it (switch ON) if this converter is positioned at either end of a CAN bus network. If the device is in the middle of a bus that is already terminated at both physical ends, the internal resistor should be disabled (switch OFF) to prevent signal reflection issues.

What software is used to configure this converter and update its firmware?

Waveshare provides dedicated configuration software for Windows PCs. You connect to the converter via its RS232 configuration port (using a USB-to-serial adapter if needed) or via its Ethernet IP address. This software allows you to set all communication parameters, configure filter rules, select conversion modes, and perform firmware upgrades.

Can this converter be powered directly from a vehicle's 12V or 24V electrical system?

Yes, its wide input voltage range of 9-36V DC makes it directly compatible with standard 12V and 24V vehicle and industrial power systems. Ensure the power source is stable and within the specified range, and use appropriate wiring and fusing as per automotive or industrial electrical standards.
