WeightWatcher UART Bridge (COM4) Driver

The WeightWatcher UART Bridge (COM4) driver enables Windows to communicate with Henning’s USB-to-UART bridge through a serial COM port. You may need it when setting up the device for the first time, reinstalling Windows, or troubleshooting a missing or unrecognized serial connection.

Key Features

• USB-to-serial communication: Provides the driver interface needed for software to exchange data with the connected UART device over USB.
• COM port access: Allows compatible applications to use the bridge as a serial port. Although the device name includes COM4, Windows may assign a different port number.
• Support for listed Windows versions: Intended for Windows 10, 8.1, 7, Vista, and XP, provided you select a package that matches your operating system and architecture.
• Device recognition: Helps Windows identify the bridge correctly so you can check its status and assigned port in Device Manager.

How to Install WeightWatcher UART Bridge (COM4) Driver

1. Check your system and device. Confirm your Windows version and whether it is 32-bit or 64-bit. If the device is unrecognized, compare its hardware IDs in Device Manager with those supported by the driver package.
2. Choose a compatible package. Before starting your WeightWatcher UART Bridge (COM4) driver download for Windows, verify the supported operating systems and source. Look for the latest version compatible with your hardware, rather than assuming every newer release will work. When comparing Windows 10/11 compatibility, note that Windows 11 is not included in the supplied support list.
3. Download and extract the files. If a free download is offered, check that it contains the actual driver rather than an unrelated installer. Extract compressed files to an accessible folder.
4. Install the driver. Follow the package’s installation instructions. If no setup program is included, open Device Manager, select the bridge or unknown device, choose the driver update option, and browse to the extracted driver folder.
5. Verify the connection. Restart if prompted, then check Device Manager for errors and the assigned COM port. Select that same port in your application and use the serial settings required by your connected equipment.

Keep the driver updated when a compatible release addresses a connection issue or supports a system change. Before an update, retain a copy of the working package so you can restore it if needed; a stable connection does not always require the newest release.
