EASY800-USB-CAB (COM3) Driver

The EASY800-USB-CAB (COM3) driver enables Windows to recognize Eaton’s USB programming cable as a serial communication interface for compatible easy800 control devices. It is intended for technicians, panel builders, and maintenance users who need to connect a PC to supported equipment for programming, configuration, or diagnostics using the appropriate Eaton software.

Key Features

• USB-to-serial connectivity: Provides the communication interface needed for compatible software to access the Eaton cable through a Windows COM port.
• COM port identification: Helps Windows list the connected cable under Ports (COM & LPT) in Device Manager. Although the device name includes COM3, Windows may assign a different port number.
• Legacy Windows support: Supported operating systems listed for this device are Windows 10, 8.1, 7, Vista, and XP. Match the driver package to your Windows version and system architecture.
• Programming connection support: Enables the cable connection used by compatible Eaton applications; the driver does not replace the programming software itself.

How to Install EASY800-USB-CAB (COM3) 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 support list.
2. Choose a compatible package. Before starting your EASY800-USB-CAB (COM3) driver download for Windows, check the package’s supported operating systems and hardware details. Look for the latest version compatible with your setup, rather than assuming every newer release supports older systems.
3. Download and prepare the files. Use a trusted source, preferably Eaton’s official support resources. If choosing a free download, verify its source and avoid unrelated download managers. Extract the archive if necessary.
4. Install the driver. Follow the package instructions, including when to connect the cable. If no installer is provided, open Device Manager, locate the cable, choose Update driver, and browse to the extracted driver folder.
5. Verify communication. Check that the device appears without a warning icon in Device Manager. Select its assigned COM port in your Eaton software, then test the connection when it is safe to do so.

Keep the driver updated when a compatible release addresses a connection problem or supports a system change. Before an update, review compatibility notes and retain the working installer so you can restore your previous setup if needed.
