Digi Communications Port (COM18) Driver

The Digi Communications Port (COM18) driver enables Windows to communicate with compatible Digi USB-connected serial hardware through an assigned COM port. It is intended for users who need to connect serial equipment, restore a missing communications port, or resolve a driver-related connection problem.

Key Features

• Serial communication support: Allows compatible applications to access connected Digi hardware through a Windows communications port.
• Device recognition: Helps Windows identify supported Digi USB hardware and load the appropriate driver components.
• COM port access: Makes the assigned port available to serial software. COM18 is a Windows port assignment, not a unique hardware model, and may differ between computers.
• Support for listed Windows systems: Driver selection covers Windows 10, 8.1, 7, Vista, and XP, subject to the compatibility requirements of the specific Digi device and package.

How to Install Digi Communications Port (COM18) Driver

1. Identify your hardware and Windows edition. Check the Digi product label or its hardware IDs in Device Manager. Confirm whether your operating system is 32-bit or 64-bit; the COM18 label alone is not enough to select a driver.
2. Choose a matching package. Before starting your Digi Communications Port (COM18) driver download for Windows, review the supported models and operating systems. Select the latest version that explicitly supports your hardware. For Windows 10/11 systems, check each OS separately: Windows 11 support is not established by the compatibility list above.
3. Download and prepare the files. Use a trusted vendor-provided package when available. A free download should still be checked for compatibility and a valid publisher signature. Extract the archive if required.
4. Install the driver. Follow the included setup instructions, including any guidance about when to connect the device. If no installer is provided, open Device Manager, right-click the relevant device, choose Update driver, and browse to the extracted driver folder.
5. Verify the connection. Restart Windows if prompted, then check Device Manager for warning icons. Confirm the assigned COM port and select that same port in your serial application, using the communication settings required by your equipment.

Keep your driver updated when Digi provides a compatible release that addresses your needs. Before an update, review the release notes and retain the working installer so you can recover if needed. A newer package is useful only when it supports your specific hardware and Windows version.
