Pro-face GPW-CB03 (COM9) Driver

The Pro-face GPW-CB03 (COM9) driver enables Windows to recognize the Digital USB programming cable and make its serial connection available to compatible Pro-face software. It is intended for users who need to connect a PC to supported Pro-face equipment for programming or data transfer, particularly when the cable is not detected or its COM port is unavailable.

Key Features

• USB communication support: Helps compatible applications communicate with supported Pro-face equipment through the GPW-CB03 cable.
• COM port access: Makes the connection available as a serial port. COM9 is the port shown in this device name, but Windows may assign a different number on another computer.
• 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: Installing the correct driver can resolve missing-driver warnings in Device Manager and allow your programming software to select the cable’s port.

How to Install Pro-face GPW-CB03 (COM9) Driver

1. Check your system. 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; Windows 11 compatibility is not confirmed here.
2. Choose the appropriate package. Before starting your Pro-face GPW-CB03 (COM9) driver download for Windows, check the package’s supported systems and source. If a free download is offered, verify that it is the correct driver rather than an unrelated installer.
3. Install the driver. Extract the downloaded archive if necessary, then follow the included instructions. Run the setup utility if provided, observing any directions about when to connect the cable.
4. Verify detection. Connect the cable and open Device Manager. Check for the device under Ports (COM & LPT) or the relevant USB category, and confirm that no driver warning appears.
5. Select the correct port. In your compatible Pro-face application, choose the COM number displayed in Device Manager. Restart the application or computer if the installation instructions require it.

Keep the driver updated when a compatible release addresses a connection issue or supports a system change. Before you update, compare the installed driver with the latest version available from a trusted source and review its compatibility notes. A working setup does not necessarily need replacement simply because another package is available.
