1. General Points
The Preh Touch Commander serves as graphical input device which makes the screen of
the computer react immediately on touching graphical operating characters (symbols,
keys, printings etc.). In this way the touchscreen allows simple, interactive handling of a
computer even for the PC-inexperienced user. For example this input media offers the
possibility of reducing training time and costs for the operating staff via a comfortable
user's dialogue. With its ergonomic design and its comfort in handling the Preh Touch
Commander is applicable in the fields of medicine, commerce, gastronomy, fast-food as
well in the restaurants and hotel business.
The Preh Touch Commander consists of two logical units, the active matrix color LCD
(TFT) and the highly sensitive touch sensor. These two units must be considered different
from each other in regard to their function. This means that the appearance of the picture
on the LCD (screen) is to be considered independent of the touch drivers. As far as the
computer is concerned the system is connected with the VGA output (LCD) as well as with
a serial interface (touching function).
The Touch Commander can thus take over the function of monitor and mouse. A
standard mouse can be used along with the Touch Commander. Both a standard
mouse and the Touch Sensor will control the position of the cursor on the screen.
The active matrix Color LCD (TFT) has a diagonal of 15" (381 mm) with a resolution of
1024x768 pixels as well as 262,144 colors. The display has an especially high degree of
brightness (typ.350cd/m²) and color brilliancy. The LCD parameters as for example
brightness, contrast, picture position etc. are adjustable via the On Screen Display (OSD).
The analog resistive 5 wire touch technology has a resolution of 1,024x1,024 points.
Inputting data is done by touching it e.g. with a finger. The activation force necessary to
register a touch is 1N. The touch surface consists of a hardened polyester foil with a high
resistance against scratches and an insensitivity to dirt, oil and water splashes. The
durability of the touch sensor is 35 million single actuation per touching point.
Multimedia models allow the possibility of giving the user audio feedback via sounds and
tones. The volume can be adjusted by a rotary control on the rear side of the base.

3. Installation of Touchscreen
Please read the following instructions prior to starting to use the Preh Touch Commander!
The following steps are necessary for a correct function of the device:
1 Adjust your computer for the proper video resolution [1024x768 / 60 Hz] and switch it
off, connect Touch, switch on computer and Touch Commander (see chapter 3.2). If
you are asked for confirming the new hardware "standard monitor", confirm according
to display instructions.
2 Adjust the video display on the Touch Commander for graphic card in the computer by
means of menu point "AUTO TUNING" of the OSD. This step is important for the best
quality of representation (see chapters 3.3).
3 Touch Commander:
Installation of touchscreen driver for the corresponding operating system
(see chapter 4).
3.1 Operating Conditions for the System
The Preh Touch Commander has been developed for the use with PC graphic adapters in
SVGA-setting with 1024x768 pixels of resolution. As an operating system it is necessary to
have either a DOS version 3.3 (or higher), Windows 3.1x, Windows 9x, Windows NT,
Windows 2000 Windows XP or OS/2.
For multimedia models a sound card with "Line Out" outputs for generating sounds is
necessary in addition.
3.2 Cable Installation and System Settings
The installation of the cables must be done with the computer switched off. Set the
correct screen resolution first. The optimum resolution is 1024x768 pixels and the refresh
rate 60 Hz.
To begin connect the VGA cable and the RS232 cable as well as the audio cable (see
pict. 3). Then plug in the AC power cable to the socket (see pict. 3).
If you now switch on the computer, the LED lights up green after about 3 seconds and the
corresponding picture appears on the screen. If the computer is in suspend or standby
mode the LED is red. If the SVGA cable between Touch Commander and computer is
disconnected, or that the computer power is switched off, the LED lights up red.

3.3 On Screen Display (OSD)

Important note to menu point AUTO TUNING:
Important information regarding the AUTO TUNING function.
Most video cards differ as to the video signal output. For this reason, the MC15
monitor may need to be readjusted after connecting it to a computer. The factory
setting of the monitor is set to produce the best results with a variety of industry
standard video cards.
To get the best picture quality, under Windows it would be best to use the
Shutdown screen when activating the AUTO TUNING menu option. By doing this,
the display tries to find the best possible adjustment. Please note that this AUTO
TUNING must be done for each display mode.
The PHASE option may also be used to manually fine tune the picture clarity after
AUTO TUNE has been done.
In some cases when using a notebook computer, it might be necessary to
deactivate the internal display of the notebook in order to obtain a good picture
quality.

4. Driver Installation
Important Note:
A new calibration is always necessary if another touchscreen was connected to the
computer or if the screen resolution was changed. This means that the calibration between
touchscreen and computer is adjusted to the mechanical features of the particular
touchscreen which was connected to the computer at that time.
A serial Touch Controller is integrated into the Touch Commander. The default setting is
9600 Bps. Normally this is clearly recognized by the setup programs. If, however, it is not
clearly recognized, the adjustment can be done manually or by restarting the
corresponding setup program.
Information for the driver installation is in the file:
D:\MC15\TOUCH\TouchKit\... (MC15 T4, T5 or T6)
D:\MC15\TOUCH\ELO\ (MC15 T7)
You can find detailed information in the path, named with your operating system. (The CD-
ROM drive of your Tocuh-CD is here defined with the letter „D“).

5. Care
Before cleaning, switch off the power supply. A soft cloth moistened with a mild cleaning
agent can be used for cleaning the housing. For cleaning the screen it is better to use a
soft paper towel moistened with a mild household cleaning agent. For cleaning the surface
do not apply the cleaning liquid directly but use a moistened paper towel. Please avoid
getting liquid into the housing.
6. Troubleshooting
6.1 General Points
Attention:
The Preh Touch Commander does not contain any electronic components that can be
replaced or repaired by the user. Consequently you should not try to do your own repair
work. Moreover, you would lose all warranty claims for this product. Activating the touch
sensor surface must not be done with a sharp object, such as credit card, long finger nails,
ring, etc. Sharp or pointed objects will cause damage to the touch sensor and are not
covered under warranty
If the Touch Commander must be returned for service, it must be packed in it's original
packing material. If this is not done, the sender will be made responsible for possible
transport damage.
6.2 Diagnostic Program
The diagnostic program COMDUMP is located in the path D:\TOUCH\MONTEST. It is
started in DOS mode or command prompt whereby the COM connection must be stated;
the baud rate is optional.
COMDUMP <number of COM port 1 or 2> [baudrate]
COMDUMP will then show you the data coming from touchscreen to COM port in
hexadecimal data on the screen. If you now contact the touch sensor the sent data should
be seen on the display.
