3.12 Touchscreen (Optional)
The touchscreen is connected to the internal RS-232 port. Its function is similar to
that of a mouse. There are 3 kinds of touchscreens that support the PPC-155T: resis-
tive, capacitive and SAW type.
It is necessary to install the touchscreen driver before it will function. The touch-
screen drivers for various operating systems are stored on the CD-ROM disc inside
the accessory box.
