USB232 Isolated port (COM22) Driver

The USB232 Isolated port (COM22) driver enables Windows to communicate with Hjelmslund’s isolated USB-to-serial device through a virtual COM port. It is needed by users connecting serial equipment to a PC over USB, particularly when the adapter is not recognized or serial software cannot open the assigned port.

Key Features

• USB-to-serial communication: Provides the interface Windows needs to make the connected adapter available to compatible serial applications.
• Virtual COM port access: Lets software communicate through an assigned port such as COM22. The actual port number can vary between computers and USB connections.
• Legacy Windows support: Listed operating systems include Windows 10, 8.1, 7, Vista, and XP. Choose a package that matches your Windows version and system architecture.
• Device recognition: Installing the correct driver can help resolve missing-driver warnings and make the adapter identifiable in Device Manager.

How to Install USB232 Isolated port (COM22) Driver

1. Check your system. Confirm your Windows edition and whether it is 32-bit or 64-bit. If comparing Windows 10/11 compatibility, note that Windows 11 is not included in the supplied support list; verify support with Hjelmslund before installing.
2. Select the correct package. Before starting a USB232 Isolated port (COM22) driver download for Windows, confirm that the package matches your Hjelmslund adapter. Look for the latest version compatible with your operating system, and use a trusted source when choosing a free download.
3. Prepare the files. Extract the downloaded archive if necessary and read any included instructions. Follow the package’s guidance on when to connect the adapter.
4. Install the driver. Run the supplied installer, if available. For a manual installation, open Device Manager, locate the adapter or unrecognized device, choose Update driver, and browse to the extracted driver folder.
5. Verify the connection. Reconnect the adapter or restart Windows if prompted. Check its assignment under Ports (COM & LPT), then select that same COM port in your serial application. Match the communication settings required by the connected equipment.

Keep the driver updated when Hjelmslund provides a compatible release that addresses your needs. Before an update, check the release notes and retain a copy of the working package so you can revert if necessary. A correctly installed driver is only part of a reliable connection—cabling, COM port selection, and serial settings also matter.
