    Control Panel > Tablet PC Settings

Step 4 - Configure touch input

  • Click Setup under the "Configure" section.

  • When prompted: "What type of screen do you want to identify?", select Touch input.

  • On your CommBox screen, you’ll see:
    “Tap this screen with your tablet pen to set it as the Tablet PC screen.”

  • Tap the CommBox screen with your finger.

  • Press Enter on the keyboard.

  • Make sure you're signed in as Administrator before configuring input.

  • Reboot the system and try again if touch or pen input doesn’t register.
