DMP connections to a touchscreen are similar to connections 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.
