If your AMX Touch Panel USB driver shows a yellow exclamation point, it likely wasn't installed correctly. To reinstall it: * Disconnect the USB cable from the panel. * Connect the USB cable to the G4 panel; a USB icon should appear in the System Tray. * Double-click the icon to see the "AMX USB LAN LINK" device. * If the driver install dialog doesn't appear, select "Properties," then "Update Driver." * Click "Next" in the Install Driver dialog to accept defaults. Ignore any warnings about the digital signature and continue the installation. The exclamation point should disappear after installation.
