SEKONIC Lightmeter L-758Series Port (COM3) Driver

The SEKONIC Lightmeter L-758Series Port (COM3) driver allows Windows to recognize the USB-connected Sekonic light meter’s communication port so compatible software can communicate with the device. It is intended for L-758Series owners setting up a computer connection or troubleshooting a missing port, an unrecognized device, or a connection problem.

Key Features

• USB communication support: Provides the driver interface needed for compatible Sekonic software to access the connected light meter.
• COM port recognition: Enables Windows to identify the device as a communication port. Although the device name includes COM3, Windows may assign a different port number on your computer.
• Support for listed Windows releases: Intended for Windows 10, 8.1, 7, Vista, and XP, subject to the specific driver package’s compatibility requirements.
• Connection troubleshooting: Installing the appropriate driver can help resolve recognition issues caused by a missing or incorrectly installed driver.

How to Install SEKONIC Lightmeter L-758Series Port (COM3) Driver

1. Check your system. Confirm your Windows version and whether it is 32-bit or 64-bit. If comparing Windows 10/11 compatibility, note that Windows 11 is not included in the listed supported systems; verify support with Sekonic before proceeding.
2. Choose the correct package. Before starting your SEKONIC Lightmeter L-758Series Port (COM3) driver download for Windows, check that the package matches your meter and operating system. Use a trusted source, and confirm that any free download is the actual driver rather than an unrelated installer.
3. Prepare the connection. Extract the downloaded files if necessary and read any included instructions. Connect or disconnect the meter as directed by the driver documentation.
4. Install the driver. Run the supplied setup program, if available. For a manual installation, open Device Manager, locate the connected device, select Update driver, and browse to the extracted driver folder.
5. Verify operation. Restart Windows if prompted, then check Device Manager for the assigned COM port and any warning icons. Open your compatible Sekonic software and select the correct port if required.

Keep the driver updated when Sekonic provides a compatible release that addresses your needs. Before you update, compare the installed driver with the latest version available for your specific Windows release, and review any installation notes. A newer package is only useful if it supports your device and system.
