[Arduino source code for KC868-A2]-05 RS485 modbus temperature humidity sensor

Hello, thank you for your video. Where can I download the PC software to read the Modbus sensor? When I use the default address 1 and 9600 baud rate same as your video, when I boot the A16v3 board, the screen displays "Loading... [sensor] and it stop at 70% .
It does not go anymore just stuck at 70% loading sensor. What is wrong? Wrong port? I need the software connect to PC to check the modbus address.
