Chapter 15 Touchscreens, Projectors, and Displays
Procedures
Connect to a Touchscreen
Tip Some touchscreens work as designed only after they are calibrated manually. If your touchscreen is one of these, its
calibration occurs during a later stage of DMP setup. The list of related topics for this procedure states where you can learn
about calibration.
DMP connections to a touchscreen are mostly the same as for other digital displays. However,
touchscreens employ a special cable that supports interactivity through touch. This might be either an
RS-232 serial cable or a USB cable, depending on the touchscreen model. Although some models
support both cable types for interactivity, you can use only one type at a time.
Before You Begin
•
Verify that your DMP model supports touchscreen technologies and that we support the touchscreen
brand, model, and device driver that you will use.
•
Check the documentation for your touchscreen to learn whether it requires a serial connection or a
USB connection to your DMP, or if it supports both.
