Brother MFC-490CW Remote Setup Port (COM4) Driver

The Brother MFC-490CW Remote Setup Port (COM4) driver helps Windows communicate with the Brother MFC-490CW’s remote setup interface so compatible Brother software can access device settings. It is intended for users setting up the multifunction device, restoring a missing port component, or troubleshooting remote configuration—not for installing a standalone camera.

Key Features

• Remote setup communication: Supports the connection between compatible Brother configuration software and the device’s remote setup interface.
• Port recognition: Helps Windows identify the Remote Setup Port component. COM4 is the assigned port name on this system; the number may differ on another computer.
• Windows compatibility options: Driver packages may be available for Windows 10, 8.1, 7, Vista, and XP. Match the package to your operating system and architecture before installation.
• Part of the Brother software setup: This component may be included in a broader Brother driver or software package rather than offered as a separate installer. It does not replace the drivers needed for printing or scanning.

How to Install Brother MFC-490CW Remote Setup Port (COM4) Driver

1. Check your Windows version. Confirm your operating system and whether it is 32-bit or 64-bit in Windows system information. For Windows 10/11 systems, verify compatibility carefully: Windows 11 is not included in the supported OS list provided here.
2. Select the matching package. When choosing a Brother MFC-490CW Remote Setup Port (COM4) driver download for Windows, confirm that the package supports the MFC-490CW and includes the required remote setup component. Choose the latest version compatible with your system.
3. Download from a trusted source. Prefer Brother’s official support resources for a free download, and avoid installers that require unrelated software or payment to unlock drivers.
4. Run the installer. Extract the files if necessary, launch the setup program, and approve administrator permissions when prompted. Connect the device only when instructed, using the connection method supported by the package.
5. Verify operation. Restart Windows if requested, then check Device Manager for warning symbols and open the compatible Brother Remote Setup utility to test communication.

Keep the driver updated when Brother offers a compatible release that addresses your issue or improves support. Before an update, review the package notes and retain a working installer if possible. If remote setup already works reliably, avoid replacing the driver with an unverified version solely because it is labeled newer.

Common Issues and Fixes

• Install fails or rolls back: Disconnect the MFC-490CW, uninstall existing Brother MFC-490CW/Remote Setup Port entries in Device Manager and Programs, reboot, then run the driver as administrator. Use the package matching your Windows version; older packages may be blocked.
• Device not detected / COM4 missing: Power on the printer, connect directly via USB (no hub), try another USB port/cable, and check Device Manager under Ports (COM & LPT). If COM4 is absent, rescan hardware or reinstall the Remote Setup Port driver.
• COM4 already in use or version conflict: Another serial/virtual COM device or older Brother software may own COM4. Remove conflicting ports/old Brother utilities, reboot, then let Windows reassign or reinstall the port; avoid running multiple Brother driver versions.
