Description
CAN FD Protocol Converter
Key Features
CAN FD TO RS232/RS485 is a bidirectional CAN FD to RS232/RS485 converter for DIN rail mounting, providing high-speed, low-latency, and stable operation. The device is easy to use and cost-effective.
Supports five data conversion modes:
- Transparent conversion
- Transparent conversion with ID
- Standard protocol conversion
- Modbus protocol conversion
- Custom protocol conversion
Enables interaction between CAN devices and serial ports, compatible with CAN FD and CAN 2.0A/2.0B protocols.
Industrial-grade design, stable operation from -40°C to 85°C, wide power range of 9V–36V, CAN FD arbitration domain baud rate of 5Kbps–1Mbps, and data domain baud rate of 100Kbps–5Mbps.
Supports parameter configuration via host computer, built-in 120Ω termination resistors (switchable via DIP switches), supports DIN rail mounting, easy to set up and install.
