4 Driver install
1) Install the driver: first insert the converter into the computer, then open the driver folder to find the driver of the corresponding
operating system, and click the exe file to install it. When the driver is successfully installed, unplug the converter and plug it
into the computer, the system will view a virtual serial port (such as: com5) in my computer device manager port to view Within
7, if the port number is too large it will affect the stability;
2) Set com port: set the virtual serial port number to the corresponding position of the software. If set to the COM port of the serial
debugging software;
3) Connect the hardware line, send data, the indicator light flashes during communication, and the USB converter works normally;
