How to Install Unitek USB to Serial Driver on Windows 7 43

If you have a Unitek USB to serial cable and want to use it on your Windows 7 43 computer, you may need to install a driver first. A driver is a software that allows your computer to communicate with the device. Without a driver, your computer may not recognize the device or function properly.

In this article, we will show you how to install the Unitek USB to serial driver on Windows 7 43 step by step. Please follow the instructions carefully and make sure you have a stable internet connection.

Step 1: Download the Driver

The first step is to download the driver from the Unitek website. You can go to and search for your product model number. For example, if you have a Unitek USB 2.0 to Serial RS232 Cable with model number Y-108, you can type "Y-108" in the search box and click on the result.

Alternatively, you can also use the links below to download the driver directly:

  • Unitek USB 2.0 to Serial RS232 Cable (Y-108)

  • Unitek USB to Serial RS232 Cable (Y-105)

Once you find your product page, scroll down and click on the "Download" button under the "Driver" section. Save the file to your computer and remember its location.

Step 2: Extract the Driver

The next step is to extract the driver from the downloaded file. The file is usually compressed in a ZIP format, so you need a software that can unzip it. You can use Windows built-in extractor or any other third-party software such as WinRAR or 7-Zip.

To extract the driver using Windows built-in extractor, right-click on the file and select "Extract All". Choose a destination folder and click on "Extract". You should see a new folder with the same name as the file.

Step 3: Install the Driver

The final step is to install the driver on your computer. To do this, open the extracted folder and look for a file named "setup.exe" or similar. Double-click on it and follow the on-screen instructions. You may need to accept some terms and conditions, choose an installation location, and restart your computer.

After installing the driver, you should be able to connect your Unitek USB to serial cable to your computer and use it with any serial devices such as printer, label writer, ISDN terminal adapter, etc. You can check if the device is working properly by going to Device Manager and looking for a COM port under Ports (COM & LPT).

If you encounter any problems while installing or using the Unitek USB to serial driver on Windows 7 43, here are some tips that may help:

  • Make sure you download the correct driver for your product model number and operating system.
