CAN FD To ETH/RS232/RS485 Protocol Converter Bidirectional DIN Rail
The CAN FD ETH RS232/RS485 Converter is a DIN-rail CAN FD to Ethernet/RS232/RS485 bidirectional converter, featuring high-speed, low-latency, stable performance, ease of use, and cost-effectiveness. It supports five data conversion modes: transparent conversion, transparent conversion with ID, standard protocol conversion, Modbus protocol conversion, and custom protocol conversion. Enables interconnection between CAN and Network port / serial port devices, compatible with CAN FD and CAN 2.0A/2.0B protocols.
Features industrial-grade design, supports -40°C ~ 85°C stable working, 9V ~ 36V wide power input, 5Kbps~1Mbps CAN FD arbitration domain baud rate, and 100Kbps~5Mbps CAN FD data domain baud rate.
Supports parameter configuration via host computer, built-in 120Ω terminal resistors (switchable via DIP switches), supports DIN-rail mounting, easy to configure and install.

Function Overview
Heartbeat Packet Function *
CAN Heartbeat Packet: Acts as a fixed query command, sending heartbeat packets through the CAN network.
Network Heartbeat Packet: Notifies the server that the device is active and maintains a stable network connection with the server.
* when using the Ethernet port and CAN as data channels
Registration Packet Function *
Allows the server to identify the source device of incoming data, or serves as an authentication key for the device to access the server’s authorized functions.
* when using the Ethernet port and CAN as data channels
