How can ydlidar g4 communicate with raspberry pi 4b?

"G4 uses the serial port to interact with external devices for commands and data. When an external device sends a system command to G4, G4 resolves the system command and returns a corresponding reply message. According to the command content, G4 switches the corresponding working status. According to the content of the message, the external system can parse the message and obtain the response data."
