My pen or finger touch operation will not interact with my computer. What should I do?

• Try the following:

  • Make sure a USB cable is connected from your computer's USB type A port to the projector's USB-B1 port.
  • BrightLink 1485Fi: If you connected to the control pad, make sure a USB cable is connected from your computer to the control pad.
  • Depending on which HDMI port and USB-B port you connect to on the projector, you may need to configure the port so the setting for the HDMI input matches the USB-B input. Go to Pen & Touch > PC Interactivity > USB-B2 to configure the port. See the options below.

    Setting	Options
    USB-B2	HDMI 1
    	HDMI 2
    	HDMI 3
    	Off

    • To use USB-B1 for interactivity on all HDMI ports, set the USB-B2 option to "Off."
    • To use USB-B2 for interactivity, set the USB-B2 option to the desired HDMI 1, 2 or 3 port.
  • If you need interactivity on a second computer, connect the USB port to the projector's USB-B2 port and one of the HDMI ports, then configure the USB-B2 setting match to the HDMI port. (The first PC can use USB-B1 for interactivity.)
