2. Windows Drivers and Installation Instructions
Before you connect your Pololu CP2102 device to a computer running Microsoft Windows, you should install its drivers:
- Download the CP2102 drivers for Windows (4MB zip).
- IMPORTANT: You must extract the zip archive into a temporary directory. attempt to double-click or run any of the files until you have extracted them.
- Open the temporary directory and run the appropriate executable. If you have a 64-bit operating system, you should run pololu-cp2102-setup-x64.exe. If you have a 32-bit operating system, you should run pololu-cp2102-setup-x86.exe.
- During the installation, Windows will ask you if you want to install the drivers. Click “Install” (Windows 8, 7, and Vista) or “Continue Anyway” (Windows XP).
- The installer should complete successfully.
Windows 8, Windows 7, and Windows Vista users: Your computer should now automatically install the necessary drivers when you connect a Pololu CP2102 device. No further action from you is required.
Windows XP users: You need to follow steps 6–10 for each new device you connect to your computer.
- Connect the device to your computer’s USB port. Your computer will detect the new hardware and open the Found New Hardware Wizard.
- When the Found New Hardware Wizard is displayed, select “No, not this time” and click “Next”.
- On the second screen of the Found New Hardware Wizard, select “Install the software automatically” and click “Next”.
- Windows XP will warn you again that the driver has not been tested by Microsoft and recommend that you stop the installation. Click “Continue Anyway”.
- When you have finished the Found New Hardware Wizard, click “Finish”.
If you now go to your computer’s Device Manager and expand the “Ports (COM & LPT)” list, you should see “Pololu USB-to-Serial Adapter” as one of the COM ports.
