If the USB driver for your AMX Touch Panel was incorrectly installed, reinstall it by following these steps: First, power up the panel without the USB cable connected. Then, plug the USB cable into the panel. A USB icon should appear in the System Tray. Double-click the icon to see the "AMX USB LAN LINK" device. If the "Install Driver" dialog doesn't appear, select the "Properties" button and then the "Update Driver" button. In the Install Driver dialog, click Next to accept the default prompts. If the OS warns about a missing digital signature, agree to continue the installation. After installation, the exclamation point should disappear.
