ET-USB/RS232 MINI (COM1) Driver

The ET-USB/RS232 MINI (COM1) driver enables Windows to communicate with Ett’s USB-to-RS232 adapter, allowing compatible serial equipment to connect through a USB port. You may need it when setting up the adapter for the first time, reinstalling Windows, or troubleshooting a missing COM port or an unrecognized USB device.

Key Features

• USB-to-serial communication: Helps Windows use the adapter to exchange data with compatible RS232 devices, such as instruments, controllers, and legacy peripherals.
• COM port access: Makes the adapter available to software that communicates through a serial port. Although the device name includes COM1, Windows may assign a different port number.
• Windows compatibility: Listed supported operating systems include Windows 10, 8.1, 7, Vista, and XP. Choose a package that matches your Windows version and system architecture.
• Device recognition: Provides the driver Windows needs to identify and operate the adapter rather than leaving it listed as an unknown device.

How to Install ET-USB/RS232 MINI (COM1) Driver

1. Check your system. Confirm your Windows version 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 supported OS list; verify compatibility with Ett before proceeding.
2. Select the appropriate package. Before starting your ET-USB/RS232 MINI (COM1) driver download for Windows, check the package’s supported systems and device details. Use a trusted source, and verify that any free download matches this adapter.
3. Prepare the files. Extract the downloaded archive if necessary and read any included instructions. Follow the package guidance on when to connect the adapter.
4. Install the driver. Run the included installer, if provided. Otherwise, open Device Manager, locate the adapter or unknown device, select Update driver, and browse to the extracted driver folder.
5. Verify the connection. Restart Windows if prompted, then check Device Manager under Ports (COM & LPT). Select the assigned COM port in your serial application and match its communication settings to the connected equipment.

Keep a working driver backed up before you update. Check for the latest version compatible with your operating system when resolving connection problems or preparing for system changes, and review any release notes before replacing a stable installation.
