ABOUT THIS MANUAL
This manual is intended as a reference guide for the Interactive Touchscreen running under
Windows XP™ or Windows Vista™.
This User Manual provides the information needed to set up the touchscreen. In addition, this
manual describes basic technical information about the touchscreen and troubleshooting.
CONTACT INFORMATION
If you have any questions or issues, please contact your original equipment supplier
SHIPPING DAMAGE/UNPACKING
Every precaution is taken in testing and packing this monitor prior to shipment.
On delivery of the monitor, check the shipping carton for damage. If any damage is seen that
could have caused damage to the contents, keep all packing materials for later inspection by
the carrier who are responsible for any shipping damage.
CARE AND CLEANING OF THE TOUCHSCREEN
Thorough cleaning of the touch screen should be performed regularly in order to assure
optimum performance.
The touch screen surface should be kept free of dust, dirt, fingerprints and other foreign
material as contamination of the screen can affect its optical properties such as brightness and
clarity of image.
Use a soft, clean, slightly damp cloth with any commercially available window cleaner for
cleaning the glass surface of the touch screen. Avoid applying the cleaner directly onto the
screen but apply it to the cloth instead.

INTRODUCTION
This manual will explain the workings and setup of the touchscreen fitted to your display. An
explanation of the monitor and its workings is covered in the Monitor Manual that came with this
product. The following pages will tell you how to install the software needed by the touchscreen to
function and go through the adjustments that user’s can change to enable the screen to perform
effectively in many different environments.
The Ma7 Driver software has been written to interface between the Interactive Touchscreen
and a computer running the Windows XP™ operating system.
Limited testing has been carried out using Windows Vista™ with no noticeable issues. Further
testing is ongoing.
Contact your supplier for more information on other operating systems.
The software comes in three executable files:
The Driver (Ma7_Driver.exe) controls the mouse pointer and activates the mouse left button in
various modes when a user touches the touchscreen.
The Control Program (Ma7_Control_En.exe) is used to set up the driver.
The Setup Program (Ma7_Setup_En.exe) is used to set up the calibration and sensitivity of the
driver from the touchscreen without using the mouse.
The configuration of the touchscreen is stored in a file called Ma7.ini, this file is saved in the
same directory as the Ma7_Driver.exe file. Once set up, only these files are required to run the
driver.
COMPATIBILITY
This program is compatible with Windows XP™.
Limited Windows Vista™ testing has not shown up any issues with running the touch software but
has shown up an issue with one of the program element; Ma7_Setup_En.exe. Further tests are
ongoing. In the mean time see the installation instructions listed for Windows Vista™.
The default settings for the touchscreen driver disable the mouse cursor
movement of the touchscreen. The user must enable this in the later stages
of the touchscreen driver setup. You must save the configuration before
closing the Ma7_Control.En.exe program after the following setup
procedure.

INSTALLATION
LOADING THE TOUCH DRIVER SOFTWARE ONTO PC
1. Switch on monitor
Do not plug the touchscreen interface cable into your computer.
2. Insert the ‘Information & Touch Software installation CD’ into the PC and follow the
automatic installation instructions.
If the installation does not start automatically;
1. Click START on the Windows™ Taskbar; then click RUN.
2. Type d:\Autorun.exe where d is the letter of your CD-ROM drive. Click OK
3. Select the ‘Touch software’ button from the on-screen menu.
The software will create a subdirectory call TouchScreen on your PC in the ‘Program Files’
sub directory and copy all the relevant files necessary to run the touchscreen into it. Once
completed, ‘launch the application’ will finish the installation. Please follow the instructions in
the next section to complete the installation and the setting up of your touch screen.
For Windows Vista™ users; When the installation has finished and the
dialogue box asks if you want to launch the application, un-tick the box. Instead, Select
‘Start’, ‘All Programs’, ‘Touchscreen’ and select Ma7_Control_En.exe to continue.

STARTING THE DRIVER CONTROL PROGRAM
Connect the touchscreen cable to a free serial port of the.
1. If the Touchscreen control panel is not already running, start the driver by clicking the icon on
the desktop or select the Windows™ START button and RUN "Ma7_Control_En.exe"with the
necessary path or double click Ma7_Control_En.exe from ‘Windows Explorer™’ or click the
short cut placed on the desktop.
When the program is started it displays the following window (Fig 1):
Fig 1
CONFIGURING THE COMMUNICATIONS PORT
When the program has loaded:
1. Select the Comms tab.
2. Select the comm port the Touchscreen is connected to.
3. Make sure the driver box called 'Present' is red and select the appropriate port that the
touchscreen is connected to.
4. Select a Baud rate of 19,200.
5. Tick the 'Open' box in the Status section.
6. When the driver recognizes the screen, the Open, Active and Valid boxes will go red (fig 2).
7. The button called Reset will reset the touchscreen driver when pressed.

EXPLANATION OF THE STATUS SECTION
1. The following explanation of the Status section assumes that the touchscreen is physically
attached to a serial port of the PC:
Open - will go red and remain red only when the driver is present, the correct port is chosen and
the Baud rate is set correctly.
If the Open box does not go red then the driver is not loaded or another driver has taken the
port.
If the Open box goes on and off repeatedly then the driver is loaded but another piece of
hardware is on that port or the Baud rate is set incorrectly.
Active - will go red and remain red only when the driver is present, the correct port is chosen
and set to the correct Baud rate and when Open is red.
Active - will flash on and off to indicate there is activity on the port but it is some other hardware
device.
Valid - will only go red and remain in this state when both Open and Active are red and the
Baud rate is set correctly.
Only when Open, Active and Valid boxes have all changed to red and remain red is the
touchscreen ready for the next stage of driver setup.
When communications exist between the driver and the touchscreen, the three boxes Size, Lost,
Rate, will display data. These indicate the following information:
Size - number of wires in the touch sensor.
Lost - how many data scans have not been captured by the driver.
Rate - how many scans of the touchscreen per 1 second.
Reasons why the driver does not see the touchscreen are usually:
•Touchscreen is on a different port to the one selected
•The Baud rate is incorrect
•Another device, driver or program is using the port

The mouse pointer will not respond to a touch until it has been enabled in the
Output section of the Control Program. Details of this will follow later in this manual.
The Reset button loads fresh data from the touchscreen. This is used as a reference for detecting
any new touches. This may be necessary if the touchscreen environment has been changed; for
example, the touchscreen has been moved.

ADJUSTING THE TOUCH SENSITIVITY LEVEL
Automatic Setup
When you receive your unit, the sensitivity settings will have been optimised when the unit was
manufactured. These settings should only be altered if you are experiencing problems such as
an electrically noisy environment. Contact your supplier if you need further explanation.
1. To select the sensitivity setup click on the Sense tab.
Fig 3
2. First set the Course Sensitivity to approximately two thirds by dragging the bar with your
mouse.
3. Set the Press Threshold to approximately one third by dragging the bar with your mouse.
4. Click on Start Auto Threshold. The following image appears:
Fig 4
5. Place your finger over the centre red circle (Fig4.) and follow it with your finger until it turns
green, then remove your finger. The automatic adjustment of sensitivity is now complete and
the screen returns to Fig 3.
Manual Sensitivity Setup
6. The Coarse Sensitivity slider is used to set the sensitivity of the touchscreen. If the slider is
set to the right, the touchscreen is more sensitive to detecting a touch. More or less
sensitivity may be required, dependent upon glass thickness or if the system is to be used
with gloved hands.
