SEL COM Port 1 (COM1) Driver

The SEL COM Port 1 (COM1) driver helps Windows recognize and communicate with the associated USB-connected serial interface from Schweitzer Engineering Laboratories. It is intended for users who need a working COM port for compatible SEL equipment and software, particularly when the connection is missing or appears with a warning in Device Manager.

Key Features

• USB-to-serial communication: Enables compatible software to communicate with the connected SEL interface through a Windows COM port.
• Device recognition: Helps Windows identify the interface correctly instead of listing it as an unknown device.
• COM port access: Makes the serial connection available to applications that require a selected COM port. Check Device Manager for the actual port assignment, as it may differ from COM1.
• Support for listed Windows systems: Supported operating systems include Windows 10, 8.1, 7, Vista, and XP. Select a package that matches your Windows version and system architecture.

How to Install SEL COM Port 1 (COM1) Driver

1. Check your system and device. Confirm your Windows version and whether it uses a 32-bit or 64-bit architecture. Verify that the driver package supports your specific SEL interface. For Windows 10/11 systems, note that Windows 11 is not included in the supplied compatibility list; confirm support before proceeding.
2. Choose the appropriate package. When selecting an SEL COM Port 1 (COM1) driver download for Windows, review its compatibility information rather than assuming the latest version supports every older operating system. Use a trusted source, and verify the publisher even if the package is offered as a free download.
3. Extract and install the driver. Unzip the files if necessary, then follow the included installation instructions. If no installer is provided, open Device Manager, select the relevant device, choose Update driver, and browse to the extracted driver folder.
4. Connect and verify the interface. Follow any instructions about when to connect the USB cable. Check Device Manager under Ports (COM & LPT) and confirm that the device appears without a warning icon.
5. Configure your application. Select the assigned COM port in your compatible SEL software and use the communication settings required by the connected equipment. Restart Windows if the installation instructions request it.

Keep the driver updated when a compatible release addresses connection issues or supports changes to your system. Before you update a working installation, review the release notes and retain the previous package so you can roll back if needed.
