Plug the USB-A (or USB-C) connector into an available port on your computer.
Driver Installation
-
Automatic: Most Windows 10 and 11 systems will automatically fetch the Prolific driver via Windows Update.
-
Manual: If the device is not recognized, visit the official UNITEK website or the SKYRS support portal to download the latest Prolific PL2303 driver package. Run the setup.exe file before plugging in the hardware.
Configuration and Verification
Once installed, you must identify which COM port the adapter has been assigned:
-
Open Device Manager: Right-click the Start button and select “Device Manager.”
-
Locate Ports: Expand the Ports (COM & LPT) section.
-
Identify Port: Look for “Prolific USB-to-Serial Comm Port (COMx).” The “x” represents the port number (e.g., COM3).
