How to Install USR602 2 Port Isolated Serial Converter Driver
- Check your Windows version and system type.
Confirm whether your installation is 32-bit or 64-bit before choosing a package. For Windows 10/11 systems, note that Windows 10 is listed as supported, but Windows 11 compatibility is not confirmed here.
- Choose a compatible driver package.
Before starting your USR602 2 Port Isolated Serial Converter driver download for Windows, verify that the package identifies this model and your operating system. Select the latest version that explicitly supports your setup. If choosing a free download, use a trusted source and check the publisher information.
- Extract the files and review the instructions.
If the download is compressed, extract it to a local folder. Follow any included guidance about whether the converter should be connected before or after installation.
- Install the driver.
Run the supplied installer if one is included. Otherwise, open Device Manager, locate the converter or unidentified USB device, select Update driver, and browse to the extracted driver folder.
- Connect and test the converter.
Restart Windows if prompted, then check Device Manager for the serial ports and any warning icons. Select the appropriate COM port in your software and match the communication settings required by the connected equipment.
Keep the driver updated when a compatible release addresses an issue or supports a change to your system. Before you update a working installation, review the package notes and retain the previous installer so you can restore your existing setup if necessary.
