3.2 Connecting the USB Controller to a Computer
- Connect the provided USB Cable to the USB port on the 4-Wire USB Controller Card.
- Connect the other end of the USB Cable to an available USB port on your computer or host device.
- The system should automatically detect the USB controller. Most modern operating systems (Windows, Linux, macOS) will install generic HID (Human Interface Device) drivers automatically, making the device plug-and-play.

4. Operating Instructions
4.1 Basic Touch Functionality
Once connected and recognized by your operating system, the touch panel will function as a standard input device. You can interact with the connected LCD display (not included) by touching the surface of the resistive touch panel.
4.2 Calibration
Resistive touch panels may require calibration to ensure accurate touch point detection, especially after initial setup or if the display resolution changes. Calibration tools are typically provided by your operating system or can be found through third-party software. Refer to your operating system's documentation for specific calibration procedures.
5. Maintenance
5.1 Cleaning the Touch Panel
- Use a soft, lint-free cloth (e.g., microfiber cloth) to gently wipe the surface of the touch panel.
- For stubborn smudges, lightly dampen the cloth with water or a mild, non-abrasive screen cleaner. Avoid spraying liquids directly onto the panel.
- Do not use harsh chemicals, abrasive cleaners, or solvents, as these can damage the touch panel surface.
5.2 Storage
When not in use, store the touch panel and controller in a dry, dust-free environment, away from direct sunlight and extreme temperatures.
6. Troubleshooting
- No Touch Response:
- Ensure all cables (FPC and USB) are securely connected.
- Verify the USB controller is receiving power (some controllers have an indicator LED).
- Try connecting to a different USB port on your computer.
- Restart your computer.
- Inaccurate Touch or Jumpy Cursor:
- Perform a touch screen calibration through your operating system settings.
- Ensure the touch panel surface is clean and free from obstructions.
- Device Not Recognized by Operating System:
- Check the USB cable for damage and try a different cable if available.
- Connect to a different USB port.
- Verify that your operating system is up to date.
