ELECOM USB-SERIAL Converter (COM4) Driver

The ELECOM USB-SERIAL Converter (COM4) driver allows Windows to recognize your Elecom USB-to-serial adapter and communicate with equipment that uses a serial connection. It is needed when connecting compatible legacy peripherals, instruments, or other serial devices through a USB port, especially if the adapter appears as an unknown device or your software cannot access its COM port.

Key Features

• USB-to-serial communication: Provides the driver interface needed for compatible applications to exchange data with connected serial equipment.
• COM port access: Makes the adapter available as a Windows serial port. COM4 is the assigned port shown in this device name; the number may differ on another computer.
• Legacy Windows support: Supported operating systems include Windows 10, 8.1, 7, Vista, and XP. Check the individual driver package for its supported Windows editions and architecture.
• Serial application compatibility: Enables software that uses COM ports to access the adapter, with communication settings selected to match the connected equipment.

How to Install ELECOM USB-SERIAL Converter (COM4) Driver

1. Identify your system and adapter. Check your Windows version and whether it is 32-bit or 64-bit, then confirm the adapter’s model or hardware ID in Device Manager. For Windows 10/11 systems, note that Windows 11 is not listed among the supported operating systems provided for this device.
2. Choose a matching package. Before starting your ELECOM USB-SERIAL Converter (COM4) driver download for Windows, verify that the package matches your hardware and operating system. If choosing a free download, use a trusted source and check its compatibility details.
3. Install the driver. Extract the downloaded archive if necessary and follow the included instructions. Run the installer if provided, or use Device Manager’s Update driver option to browse to the extracted driver folder.
4. Connect and verify. Follow any instructions about when to plug in the adapter. Open Device Manager and look under Ports (COM & LPT) to confirm that it appears without a warning icon.
5. Configure your application. Select the COM port displayed in Device Manager and match the baud rate, parity, and other serial settings to your connected equipment. Restart Windows if prompted.

Keep a working driver backed up before applying an update. Check for the latest version compatible with your exact adapter and Windows installation, particularly when troubleshooting connection problems; a newer release is not necessarily suitable for every older operating system.
