Installing the Monitor Chapter 2
Connect the Optional Touch Screen Interface
An optional touch screen provides a high-resolution touch input system. The
driver software included with the monitor allows the touch screen to function
with many Windows and Linux operating systems such as a pointing device or
mouse.
A touch screen interface to the computer can be configured using either the serial
RS-232 connection or USB connection.
Connect the Optional Serial RS-232 Touch Screen Interface
The RS-232 DB9 (female) D-shell connector on the bottom side of the monitor
provides the serial touch screen interface connection to the host.
Follow these directions to connect the touch screen interface.
1. For units with the touch screen option, connect one end of the included
touch screen serial cable to the RS-232 port connector on the monitor.
2. Connect the other end of the cable to a serial port on the host computer.
3. Tighten the captive screws on the cable connector to secure it.
The table shows how to connect the RS-232 wirings to the host serial port.
