If
you connected your computer to a
Computer or
HDMI port on the projector, you also need to
connect the USB cable so you can use the pens and your fingers with
your computer.
Note: A Touch
Unit is optional for the BrightLink 1480Fi
and must be installed for finger touch operation.
Note: If your
computer is connected to an HDMI input on the control pad
(BrightLink 1485Fi), connect the computer's
USB cable to the control pad's USB-B port.
