USB485 Isolated 2 wire port (COM15) Driver

The USB485 Isolated 2 wire port (COM15) driver enables Windows to communicate with Hjelmslund’s isolated USB-to-RS485 adapter through a serial COM port. It is intended for users connecting compatible two-wire RS485 equipment, such as industrial controllers or monitoring devices, to a PC without a built-in RS485 interface.

Key Features

• USB-to-serial communication: Provides the Windows interface needed for serial applications to exchange data with connected RS485 equipment.
• COM port access: Makes the adapter available to compatible software as a serial port. COM15 is the port assignment shown for this device; Windows may assign a different number after installation.
• Two-wire RS485 operation: Supports communication through the adapter’s two-wire interface. Electrical isolation is provided by the adapter hardware, not added by the driver.
• Support for listed Windows systems: Intended for Windows 10, 8.1, 7, Vista, and XP, subject to the compatibility details of the selected driver package.

How to Install USB485 Isolated 2 wire port (COM15) Driver

1. Check your Windows configuration. Confirm your Windows version and whether it uses a 32-bit or 64-bit architecture. For Windows 10/11 systems, note that Windows 10 is listed as supported, but Windows 11 compatibility is not confirmed here.
2. Choose a matching package. Before starting your USB485 Isolated 2 wire port (COM15) driver download for Windows, verify that the package identifies Hjelmslund and supports your adapter and operating system. If a free download is offered, check its source and compatibility before proceeding.
3. Install the driver. Extract the downloaded archive if necessary, then follow the included setup instructions. If no installer is supplied, use Device Manager’s “Update driver” option and browse to the extracted driver folder.
4. Connect and verify the adapter. Follow any connection instructions supplied with the package. Open Device Manager and check under “Ports (COM & LPT)” for the adapter and its assigned COM number.
5. Configure your application. Select the matching COM port and set the baud rate, parity, and other serial parameters required by your connected equipment. Restart Windows if prompted.

Keep the driver updated when a compatible release addresses a connection problem or supports a system change. Before you update, check that the latest version still supports your Windows edition and adapter, and retain a working installer in case you need to roll back.
