Extract Files: A small window will appear. Click "Extract" to unpack the driver files into a temporary folder.

Disconnect the Device: Unplug the USB device from your computer before starting the installation to prevent hardware conflicts.

If the driver fails to install or the device isn't recognized, consider these common fixes:

Run as Administrator: Right-click on the downloaded Cdm20830 -setup.exe file and select "Run as Administrator."

Check Device Manager: Open Device Manager (Win + X > Device Manager). Look under "Ports (COM & LPT)" or "Universal Serial Bus controllers" to see if the device appears without a yellow exclamation mark.

Accept License Agreement: Read and accept the FTDI license terms.

FTDI VCP (Virtual COM Port) Driver: This makes the USB device appear to your operating system as a standard RS232 serial port.
