7.1 General Information
The touch screen consists of a pressure-sensitive resistance array that is
continuously monitored by a controller. When the screen is touched, the
coordinates of the position affected are computed based on the screen resolution
used and forwarded to the controller. Since the touch screen function is based on
resistance, users can operate it using an appropriate object such as the blunt end
of a pen or pencil or when wearing gloves.
Note
Do not use pointed objects to operate the screen, since these can damage the
polyester membrane surface.
This screen surface is waterproof and can be cleaned with a mild, non-abrasive
cleaner.
The touch screen system consists of the touch screen sensor and the touch
screen controller. The FI45 uses the built-in touch controller E271-2210 which is
connected to the RS232 interface of the basic module. The external cable (already
plugged in) connects the touch controller to the external COM2 port.
The plug-in jumpers on the mini circuit board of the touch controller are preset by
the manufacturer; these connections must not be changed.
There is no touch pad available for these devices. The necessary software for
operating the touch screeen is pre-installed.
The following section applies only to the first installation of your device.
