Fronius Converter USB (COM5) Driver

The Fronius Converter USB (COM5) driver helps Windows recognize your Fronius USB converter and makes its serial COM-port connection available to compatible software. It is intended for users who need to connect supported Fronius equipment to a PC, restore an unrecognized connection, or reinstall the driver after a Windows setup.

Key Features

• USB-to-serial communication: Enables compatible applications to communicate with the converter through a Windows COM port.
• Device recognition: Helps Windows identify the connected converter rather than leaving it listed as an unknown device.
• COM-port access: Allows you to check the assigned port in Device Manager and select it in your Fronius application. Although the device name includes COM5, Windows may assign a different port.
• Legacy Windows support: Listed operating systems include Windows 10, 8.1, 7, Vista, and XP. Choose a package that matches your Windows version and system architecture.

How to Install Fronius Converter USB (COM5) Driver

1. Check your Windows system. Confirm your operating system and whether it is 32-bit or 64-bit. For Windows 10/11 systems, note that Windows 10 is listed as supported, while Windows 11 compatibility should be verified with Fronius before installation.
2. Select the appropriate package. Before starting a Fronius Converter USB (COM5) driver download for Windows, verify the supported device and operating system. Prefer an official source or a trusted free download with clear package details.
3. Prepare the files. Extract the downloaded archive if necessary and review any included instructions. Connect or disconnect the converter as directed by the package documentation.
4. Install the driver. Run the provided installer, if available. For a driver-only package, open Device Manager, locate the converter, choose Update driver, and browse to the extracted driver folder.
5. Confirm the connection. Restart Windows if prompted, then check Device Manager for the converter and its assigned COM port. Select that same port in your compatible Fronius software and test communication.

Keep your driver updated when Fronius provides a compatible release that addresses connection issues or supports your software setup. Check the release notes before choosing the latest version, and avoid replacing a working driver solely because another package has a higher version number. A suitable update should match both your converter and your operating system.
