The Belkin USB to Serial Adapter connects compatible serial equipment to a Windows computer through a USB port. Its driver allows Windows to recognize the adapter and create a virtual COM port that serial applications can use to communicate with the connected device.

Key Features

• Virtual COM port access: Makes the adapter available to software that communicates through a standard serial port, including terminal utilities and equipment configuration tools.
• USB-to-serial communication: Enables data exchange between your computer and compatible serial hardware, such as modems, control equipment, and console interfaces.
• Serial connection settings: Allows supported applications to use the baud rate, parity, stop bits, and flow control required by the attached equipment.
• Windows device integration: Helps Windows identify and manage the adapter through Device Manager. For Windows 11, 10, 8, or 7, choose a driver that explicitly supports both your operating system and the adapter’s exact model or hardware revision.

How to Install

1. Identify your adapter and Windows version. Check the model number on the Belkin adapter’s label and confirm whether your Windows installation is 32-bit or 64-bit. Driver compatibility can vary between adapter revisions, so the product name alone may not be enough to select the correct package.

1. Download the matching driver. Select a trusted driver package that lists your model and operating system. Extract the files if they arrive in a compressed folder, and review any included installation instructions.

1. Run the installer. If a setup program is included, launch it and follow the prompts, granting administrator permission when requested. Connect or disconnect the adapter as directed by the installer.

1. Install manually if needed. If there is no setup program, connect the adapter and open Device Manager. Locate the unrecognized adapter, select Update driver, then choose the option to browse your computer and point Windows to the extracted driver folder.

1. Verify the serial connection. After installation, check Ports (COM & LPT) in Device Manager for the adapter’s assigned COM number. Select that port in your serial application and match its communication settings to the connected equipment. Restart Windows if prompted.

If Windows does not recognize the adapter, try another USB port and recheck the driver’s model compatibility. Older adapter revisions may not have official driver support for every listed Windows version.

Common Issues and Fixes

• Install fails or rolls back: Run the Belkin installer as administrator and use the driver package that matches your Windows version. Reboot before retrying; if setup still fails, extract the driver and update it manually via Device Manager.
• Device not detected / no COM port: Plug the adapter directly into another USB port, not a hub. Check Device Manager for an unknown device or missing Ports entry, then unplug/replug and manually point the driver update to the extracted Belkin files.
• Version conflicts or Code 10: Uninstall existing USB-to-serial drivers, including hidden devices, reboot, then install the Belkin driver. If the COM number conflicts, open Ports > Properties > Port Settings > Advanced and assign an unused COM port.
