MicroLink HART Protocol Modem (COM2) Driver

The MicroLink HART Protocol Modem (COM2) driver enables Windows to recognize Microflex’s USB modem and provides the serial communication interface used by compatible HART software. It is intended for technicians and engineers who connect a PC to HART field instruments for configuration, diagnostics, or maintenance.

Key Features

• USB-to-serial communication: Makes the modem available through a virtual COM port so compatible applications can communicate with connected HART devices.
• HART software connectivity: Provides the Windows interface required by supported instrument-management tools; the driver does not replace the HART application itself.
• Support for listed Windows systems: Supported operating systems include Windows 10, 8.1, 7, Vista, and XP. Choose a package that matches your Windows version and system architecture.
• COM port identification: Lets you check the modem’s assigned port in Device Manager. Although the device name includes COM2, Windows may assign a different port depending on your system.

How to Install MicroLink HART Protocol Modem (COM2) Driver

1. Check your Windows configuration. Confirm your operating system and whether it is 32-bit or 64-bit before selecting a package. For Windows 10/11 systems, note that Windows 10 is listed as supported, while Windows 11 compatibility requires separate confirmation from Microflex.
2. Select the appropriate download. Before starting your MicroLink HART Protocol Modem (COM2) driver download for Windows, review the package’s compatibility information. Look for the latest version that explicitly supports your setup, and verify the source of any free download.
3. Install the driver. Extract the downloaded files if necessary and follow the included instructions. Run the installer if one is provided, connecting the USB modem when prompted.
4. Confirm device recognition. Open Device Manager and locate the modem, typically under Ports (COM & LPT). If Windows requests a driver, use Update driver and browse to the extracted driver folder.
5. Configure your HART application. Select the COM port shown in Device Manager, then test communication with your instrument using the modem’s documented connection procedure. Restart Windows if the installer requests it.

Keep the driver updated when Microflex provides a compatible release that addresses your needs. Before an update, review the release notes and confirm support for both your Windows version and HART software, especially on older systems.
