Digi Communications Port (COM15) Driver

The Digi Communications Port (COM15) driver helps Windows recognize a compatible Digi USB-connected serial interface and makes its COM port available to communication software. You may need it when setting up Digi hardware, restoring a missing port, or troubleshooting an application that cannot connect through COM15.

Key Features

• Serial communication support: Allows compatible applications to exchange data with connected equipment through a Windows COM port.
• Device recognition: Helps Windows identify the supported Digi interface rather than leaving it listed as an unknown device.
• COM port configuration: Provides access to supported serial settings, such as baud rate and flow control, through Windows or your communication application.
• Legacy Windows options: Driver packages may support Windows 10, 8.1, 7, Vista, and XP; check the individual package for your hardware model and system architecture.

How to Install Digi Communications Port (COM15) Driver

1. Identify your hardware and Windows version. Open Device Manager and check the device’s properties. If the model is unclear, use its hardware IDs to confirm compatibility. COM15 is an assigned port number, not a unique hardware model.
2. Choose a matching package. Before starting your Digi Communications Port (COM15) driver download for Windows, confirm that the package supports your Digi device and your 32-bit or 64-bit operating system. Select the latest version that explicitly supports both.
3. Download and prepare the files. Obtain the driver from a trusted source, checking any free download for a valid publisher signature where available. Extract the archive if necessary and review the included instructions.
4. Install the driver. Run the supplied installer and follow its connection prompts. If no installer is provided, open Device Manager, right-click the device, select Update driver, and browse to the extracted driver folder.
5. Verify the connection. Restart Windows if requested, then check Ports (COM & LPT) in Device Manager. Confirm that the Digi port appears without a warning icon and select its assigned COM number in your application—it may differ from COM15.

Keep the driver updated when Digi provides a compatible release that addresses your needs, and review release notes before you update a working setup. For Windows 10/11 systems, verify support separately: Windows 10 is listed for this device, but Windows 11 compatibility is not confirmed by the supplied information. Avoid forcing an older package onto an unsupported system.
