2. Select the driver corresponding to your operating system.

3. If the driver is similar to setup.exe.

or

Install.exe

Install.exe, insert "USB to RS-232 serial port line", and the system will prompt you to find new hardware, so that you can determine the directory of the driver and point the directory to the location of the driver on the CD. Then click "Next". Generally speaking, it's OK music.
