Description

This industrial protocol converter facilitates robust communication between CAN FD (Controller Area Network with Flexible Data-rate) buses and legacy RS232 or RS485 serial interfaces. It operates in five configurable modes, including transparent transmission, Modbus protocol conversion, and custom frame mapping, allowing for tailored integration into complex control architectures.

Engineered for harsh environments, the module features a wide operating temperature range, surge protection, and a DIN-rail mountable metal housing. Its wide input voltage tolerance from 9V to 36V DC ensures compatibility with standard industrial power supplies, making it suitable for deployment in factory automation, robotics, electric vehicle systems, and remote monitoring applications.

Key Features

  • Bidirectional conversion between CAN FD/CAN 2.0 and RS232 or RS485 serial interfaces.
  • Supports five operational modes: transparent, Modbus Master, Modbus Slave, and custom protocol conversion.
  • High-speed CAN FD support with configurable baud rates: arbitration domain (5 Kbps–1 Mbps) and data domain (100 Kbps–5 Mbps).
  • Industrial-grade construction with -40°C to +85°C operating temperature and wide 9–36V DC input range.
  • Integrated ESD protection (8 kV air discharge, 6 kV contact discharge) and switchable 120Ω CAN termination resistor.
  • Standard DIN-rail mounting for easy installation in control cabinets and industrial enclosures.
  • Configurable via dedicated host configuration software and AT commands for flexible setup.
  • Single-channel design ensures focused and reliable point-to-point or network gateway functionality.

Applications

  • Industrial automation gateways for connecting PLCs with CAN-based motor drives or I/O modules.
  • Electric vehicle (EV) and battery management system (BMS) data logging and diagnostic interfaces.
  • Building management systems (BMS) integrating HVAC controllers over RS485 Modbus with CAN FD vehicle networks.
  • Robotics control systems requiring communication between CAN-based servo drives and a central RS232/485 control panel.
  • Remote monitoring and data acquisition (DAQ) in harsh environments like renewable energy plants or oil & gas facilities.

Frequently Asked Questions

What is the difference between the RS232 and RS485 output on this converter?

This converter provides a single serial channel that can be configured as either RS232 (point-to-point, voltage-based) or RS485 (multi-drop, differential). The selection is made via hardware jumpers or software configuration. RS485 is preferred for longer distances and noisy industrial environments, while RS232 is suitable for direct connections to legacy equipment like PCs or displays.

How do I configure the Modbus conversion mode on this device?

The converter is configured using the dedicated Waveshare host configuration software or via AT commands sent through its serial port. You can set it to act as a Modbus Master (polling RS485 devices) or Modbus Slave (responding to CAN requests). The software allows mapping of specific CAN IDs to Modbus register addresses for seamless protocol translation.

What power supply is required for the 9-36V DC input?

Any stable DC power source within 9V to 36V range is suitable, such as a 12V or 24V industrial switching power supply. The wide input range ensures compatibility with common vehicle electrical systems (12V/24V) and standard industrial control cabinet voltages (24V). Ensure the power supply can deliver sufficient current, typically a few hundred milliamps.

Does this module include the necessary termination resistors for CAN bus?

Yes, the module includes a built-in 120Ω termination resistor for the CAN bus line, which can be enabled or disabled via a switch. This resistor should be enabled only if the module is at one end of the CAN bus network. If multiple devices with termination are present on the same bus, ensure only the two devices at the physical ends have termination enabled to prevent signal reflection.
