Brother MFC-9140CDN Remote Setup Port (COM8) Driver

The Brother MFC-9140CDN Remote Setup Port (COM8) driver helps Windows recognize the USB-connected remote setup interface used to communicate with your Brother multifunction printer. It is intended for users who need Brother’s Remote Setup software to access supported device settings, or who see an unrecognized remote setup port in Device Manager.

Key Features

• Remote setup communication: Provides the driver interface needed for compatible Brother software to communicate with the printer’s remote setup function.
• USB device recognition: Helps Windows identify the remote setup port separately from the printer’s printing and scanning interfaces.
• COM port identification: Supports the interface shown as COM8 on this system. Windows may assign a different COM number on another computer or after reconnecting the device.
• Legacy Windows support: Intended for Windows 10, 8.1, 7, Vista, and XP when used with the appropriate Brother package for your operating system and architecture.

How to Install Brother MFC-9140CDN Remote Setup Port (COM8) Driver

1. Check your Windows version. Confirm your operating system and whether it is 32-bit or 64-bit. If comparing Windows 10/11 options, note that Windows 11 is not included in the supplied compatibility list; verify support before proceeding.
2. Choose a compatible package. For a Brother MFC-9140CDN Remote Setup Port (COM8) driver download for Windows, select a Brother-provided package that explicitly matches your printer model and Windows version. Prefer the latest version available for that combination.
3. Download and prepare the installer. Use a trusted source for the free download, and check the package’s installation instructions. Extract the files if necessary, and connect or disconnect the USB cable as directed.
4. Install the driver. Run the installer and follow its prompts. If the package contains only driver files, use Device Manager’s Update driver option and browse to the extracted folder.
5. Verify the connection. Restart Windows if requested, then check Device Manager for warning icons. Open compatible Brother Remote Setup software to confirm communication with the device. Printing and scanning may require additional Brother drivers.

Keep the driver updated when Brother offers a compatible release that addresses your issue or improves support. Before you update a working installation, review the release notes and confirm OS compatibility; a newer package is not necessarily suitable for older Windows versions.
