Industrial Grade Design
Supports Multiple Conversion Modes
Transparent conversion, transparent conversion with ID, standard conversion, Modbus protocol conversion, and custom conversion with custom headers and trailers
Transparent Conversion
Achieves original conversion between CAN FD frames and serial/Ethernet frames
Transparent Conversion with ID
Transmits ID information from serial/Ethernet frames to CAN FD frames
Standard Conversion
Conversion between 13-byte standard CAN frame format and 69-byte standard CAN FD frame format
Modbus Protocol Conversion
Implements Modbus data transmission over CAN bus through packet segmentation and reassembly
Custom Protocol Conversion
Users can customize frame headers and trailers to achieve bi-directional data conversion
3 Frame Filtering Methods, 32 Sets of Configurable Filters
Supports receiving only extended frames, receiving only standard frames, and custom frame ID reception. In custom mode, users can configure up to 32 sets of filtering methods to avoid large volumes of data interference
Parameter Configuration via Host Computer
Function Overview
Heartbeat Packet Function *
CAN Heartbeat Packet: Acts as a fixed query command, sending heartbeat packets over the CAN network.
Network Heartbeat Packet: Informs 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 transmission 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 authorized server functions.
* when using the Ethernet port and CAN as data transmission channels
Application Scenarios
BMS Battery Monitoring
Industrial Automation
EV Charging
