How to Install PU23 (COM3) Driver

1. Check your system details. Confirm your Windows version and whether it uses a 32-bit or 64-bit architecture. For Windows 10/11 systems, note that Windows 10 is listed as supported, while Windows 11 compatibility should be verified with the vendor before installation.
2. Choose a compatible package. Before starting your PU23 (COM3) driver download for Windows, review the package details and source. Look for the latest version compatible with your system, rather than assuming the newest release supports every older Windows edition. If offered as a free download, check that it is the actual driver rather than an unrelated installer.
3. Prepare the installation files. Extract the downloaded archive if necessary and read any included instructions. Follow the package guidance on when to connect the USB device.
4. Install the driver. Run the supplied setup program, if available. Alternatively, open Device Manager, locate the PU23 or unrecognized device, select Update driver, and browse to the extracted driver folder.
5. Verify the connection. Restart Windows if prompted, then check Device Manager for warnings. Confirm the assigned COM port and select that same port in the software you use with the device.

Keep the driver updated by checking for compatible releases from a trusted source, especially when troubleshooting or changing Windows versions. Before you update a working installation, review any release notes and keep a copy of the previous driver so you can roll back if needed.
