2. Connect the input end to the computer USB port, and connect the TX and RX of the output end with jumper caps.
At this time, the LED power indicator light will light up

3. At this point, open the USB device viewer or the built-in device manager on the computer,
which will display information about the USB device and four COM ports

4. Open the serial debugger, select one of the serial port numbers, choose the appropriate baud rate, open the serial port and send data.
The window will receive this data without packet loss, as shown in the following figure:
