How to Operate
The Touch Screen responds to the slightest contact, therefore you do not
have to apply much pressure when working with the screen. This does not
only safe time, but is also kind to your joints!
Touching the touch glass has the same effect as clicking the left mouse
button. You only need to apply a little pressure with the fingertip. In this ca-
pacitive process only fingertip contact is recognized. The screen does not
react in any way if touched, for example, with a pencil or a glove.
You can adjust the brightness and the loudness with the thumb wheels
located down to the right of the front of the screen.
Cleaning Instructions
Always turn off the system before cleaning. The glass surface of your
Touch Screen should be cleaned with a mild, commercially available glass
cleaning product. All pH neutral materials (pH 6 to 8) are good for clea-
ning. Cleaners with pH values 9 to 10 are not recommended. Cleaning
with water and isopropyl alcohol is possible as well. Do not use solvents
containing acetic acid. Use a soft, fine-meshed cloth to clean the surface.
Dampen the cloth slightly and then clean the screen.
A wrong maintenance may cause damages to the screen, which are not
covered by guarantee or warranty.
COM Board for Touch Screen
The COM Board is an additional board for the LCD-Controller-A with an
ISA bus interface that has 2 or 4 COM interfaces (COM5, 6, 7, 8). COM5
and COM6 are linked to the BA72 controller via a plug connector. COM5
is a reduced COM interface for RxD and TxD signals and is intended for
the use of the (optional) touch function.
As an option the COM board can be equipped with a COM7 and a COM8
interface. These can alternatively be operated as power-supplied interfa-
ces (COM7* /COM8*) or as powerless interfaces (COM7 / COM8).
