3M™ MicroTouch™ Software MT 7 User Guide  
If this is a new installation, the default option reflects the driver that best suits your  
system.  
If this is not a new installation, the chosen option reflects the driver you currently  
use.  
Note that some systems may not show a touch digitizer driver option. This option  
appears only if your system supports Windows' Tablet PC. Tablet PC is supported on  
Windows® 7, Vista, and some XP operating systems.  
Also, note that each driver presents different functions. Choose a driver based on what  
will suit your needs best.  
Touch Digitizer- Has tablet features when used in conjunction with Windows 7. This  
includes flicking, an onscreen keyboard, and a press, hold, liftoff action for the right-  
click function.

Utilities and Tools  
The Blank Cursor option enables you to hide the cursor. By selecting this, MT 7  
Software installs a blank cursor on your system. To always hide the cursor, open the  
Windows® Control Panel, select mouse settings and then browse to the MicroTouch  
folder and select blank cursor.  
Performing a Silent Install  
If you have to perform multiple system installations, you may want to take advantage of  
the MT 7 software silent install.  
To begin, you must create a silent install script that contains the recorded installation  
instructions. You create this script by running the Setup program in record mode. During  
a silent install, the Setup program receives input from the recorded install script rather  
than from a user. Once you record an installation script, you can run it on as many  
similar systems as you like.  
The first step in producing a silent installation is to record your standard installation.  
Open a command line window and set your working directory to the directory containing  
the MT 7 for Windows® setup program. Issue the command "setup -r" and run the  
installation normally.  
When the installation finishes, it creates a recording file, setup.iss, in your Windows®  
system directory (such as C:\Windows). Copy this file to the directory containing the MT  
7 for Windows® setup program.  
To run the silent installation, simply issue the command "setup -s". This replays the  
installation you recorded above.

12  
3M™ MicroTouch™ Software MT 7 User Guide  
Note that the silent installation fails if the installer reacts differently than when it was  
recorded. For example, if you record an installation using the "Upgrade" option and  
replay it on a system without MT 7 for Windows, the installation may fail. You should  
test the silent installation on all expected configurations.  
Since the recording process creates a file, the MT 7 program must be on a hard drive and  
not on a CD-ROM. Once the file is created, you can make a CD-ROM, or equivalent  
media, with the distribution files and the setup.iss file. Your use of this CD-ROM is  
subject to the license agreement of this software. This feature does not give you the right  
to distribute this software if that right is not already granted to you by the license  
agreement.  
Customizing Your Settings  
Once you have installed MT 7 software, you can optimize the performance of the sensor  
using the MT 7 Control Panel. You can adjust settings for touch sounds, double-click  
speed, and double-click area (not applicable to WIN CE or Linux® systems).  
Note: You can define touch settings using the MT 7 Control Panel. MT 7 stores the  
touch settings in the Windows® system registry. Whenever you save changes to the MT7  
Control Panel, MT 7 software records the new settings in the system registry. These  
changes take effect immediately.  
Uninstalling MT 7 Software  
The Uninstall program removes all MT 7 software components from your computer.  
These components include MT 7 software files, directories, folders, and registry key  
items. The Uninstall program also removes all MT 7 software entries from the system  
registry files.  
Note: For details on how to uninstall MT 7 for Windows® CE, Windows® XP  
Embedded, and Linux, refer to Chapters 3, 4, and 5.  
To uninstall MT 7 software:  
1. Close MT 7 software if it is open.  
2. Click on Start Programs MicroTouch MT 7 Uninstall MT 7 Software  
The path may be different if you performed a custom installation and chose a custom  
name for the MT 7 software program group.  
3. Follow the onscreen instructions to remove MT 7 software. 3M Touch Systems  
strongly suggests you reboot your system when complete.

3M™ MicroTouch™ Software MT 7 User Guide  
Main Tab  
This tab covers sensor calibration as well as basic support information.  
Calibration  
The calibration process aligns the sensor with the underlying video. Specifically,  
calibration defines the dimensions of the active area of the sensor and locates the center  
of the sensor. If the sensor is not calibrated, the active area of the sensor may not be  
aligned properly or may be unnecessarily small.  
You should calibrate the sensor in the following cases:  
Any time you change the size and position of the video image by adjusting the  
horizontal and vertical controls on your display.  
Any time the cursor does not follow the movement of your finger, or does not reach  
the edges of the sensor. If you continue to need additional accuracy along the edges,  
use the Edge Adjustment tab.

Calibrating the Sensor  
1. Select the Main tab.  
2. Click the Calibrate button.  
Note: If you are using a stylus (pen) and you are in Pen/Finger mode, a dialog will  
ask whether you wish to calibrate using Pen or Finger. Calibrate using each option  
separately and when you are done, MT 7 will restore your touch mode to  
Pen/Finger.  
3. A calibration target appears in the lower left corner of the sensor.  
Note: If you press Escape or do not touch the sensor within twenty seconds, the  
system automatically cancels the calibration process with no change to the current  
settings.  
4. Touch the sensor positioning your fingertip to completely cover the green target.  
This position is calculated upon liftoff and when you remove your finger, the target  
should turn red.  
When touching the calibration target, make sure to:  
Face the display directly.  
Perform the calibration in the position (sitting or standing) you expect to  
normally use the sensor.  
Touch the calibration target firmly and precisely with your fingertip. During  
Calibration, be careful to keep your fingernails and other fingers away from the  
sensor as you touch the target.  
5. Repeat these instructions for additional calibration targets.  
6. Once you have calibrated the sensor, a dialog box will appear to ask if you wish to  
test, accept or cancel this calibration.  
If you select Accept, then the new calibration settings are automatically  
accepted.  
If you select Test, then a Draw (refer to the Tools tab for more details) screen  
appears. When you exit Draw mode, a dialog will prompt, “Are you satisfied  
with the results?”  
Selecting Yes will keep the new calibration settings.  
Selecting No will restore the original (pre-calibration) settings.  
If you select Cancel, the original settings will be restored without change

3M™ MicroTouch™ Software MT 7 User Guide  
Testing the Calibration  
If you accidentally liftoff from the sensor in the wrong place during calibration, you will  
distort the sensor calibration. Test by touching several points on the sensor to make sure  
you are satisfied with the calibration results. The cursor should be located underneath  
your finger or pen when you touch the sensor. Repeat the Calibration process until you  
are satisfied. Recalibrate the sensor if any of the following tests fail. Touch random  
points on the sensor. The cursor should be located underneath your finger or pen when  
you touch the sensor.  
Drag your finger across the sensor and check that the cursor follows your  
movements.  
Touch each corner and along the edges of the sensor. Verify that the cursor reaches  
the full image area of the sensor. Be sure you can touch and activate all icons and  
menus across the entire sensor.  
If you are using a pen stylus, be sure to perform the calibration procedure using the  
pen.  
If you need to recalibrate the sensor, make sure to touch the targets carefully. It is  
possible that one of your touches did not register properly or you accidentally  
touched the sensor in the wrong place during calibration. For example, if you touch  
beyond the targets or into the non-image area, you will distort the sensor calibration.  
Support Information  
This information helps identify your system setup for troubleshooting purposes. If for  
any reason you need to call Technical Support, this information will be useful.  
Controller ID  
On the Main tab, this is an information-only field in a single controller situation – if you  
have more than one controller you can select the specific controller you want to adjust.  
This field identifies the controller(s) attached to your system. It will display unique

Touch Settings Tab  
The Touch Settings tab enables you to customize the response of your sensor. You can  
change the way the system responds to your touch, add a right-click tool to your desktop,  
tell your system to beep on touch, and define the double-click speed and area of your  
touch.  
Touch Modes  
The available Touch Mode options are Drawing, Touchdown, and Liftoff.  
Drawing Mode (Default Value)  
Drawing Mode is most useful for draw, paint, illustration, and graphics applications. In  
Drawing Mode, a touch is equivalent to pressing and holding down the mouse button.  
This is considered the easiest mode to use with an immediate reaction to touch. Lifting  
off is equivalent to releasing the mouse button.  
To click, touch the object. Lift off the sensor.  
To double-click; touch the object twice quickly at the same location.  
To drag, touch the object. Slide your finger to the new location. Lift off the sensor.

3M™ MicroTouch™ Software MT 7 User Guide  
19  
Touchdown Mode  
Touchdown Mode enables you to create an immediate button action as soon as you touch  
the sensor. In Touchdown Mode, you cause a button down at the cursor location, with a  
short pause and then a button up. You can leave your finger on the sensor but only a  
single touch is registered until you lift your finger off the sensor and touch down again.  
Touching the sensor is equivalent to pressing and releasing the mouse button. The action  
occurs as soon as you touch the sensor. This mode is best for button-based applications  
(like a calculator). Drawing or dragging is not supported in this mode.  
Liftoff Mode  
Liftoff Mode enables you to position the cursor where you want before creating a button  
action. In Liftoff Mode, the cursor will follow your finger for a more accurate touch.  
When you want to select an item, lifting your finger off the sensor will cause a button  
down, short pause, and then a button up to occur.  
Touching the sensor is equivalent to moving the mouse position. The button down/button  
up action occurs when you remove your finger from the sensor. This mode is useful for  
applications requiring greater accuracy because it lets you carefully position the cursor  
before acting on it. Drawing or dragging is not supported in this mode.  
Right-Click Tool (not available on Linux®)  
This option places an icon on the desktop (always on top of your application) that allows  
you to select which mouse button to activate on touch. This icon can be dragged  
anywhere on the screen. In the image you will see that either the right-click or left-click  
mouse button is green. This is the active button. Note that this works for the next click  
action only. After you have selected the right-click option and then touched the screen  
causing the right-click menu to appear, the mouse will automatically revert back to its  
original left-click state. You can position this icon anywhere on your desktop by  
selecting it, pausing until the four-pointed arrow appears, and dragging it wherever you  
want.  
Left button is typically used for normal select and normal drag. Right button is typically  
used for applet properties such as context menu and special drag.  
For Windows® 7 (when used with the touch digitizer option) press and hold your finger  
down on the screen. A ring will appear around the point at which you are touching and  
upon liftoff the right-click menu will appear.  
Touch Sound  
Select audible beep on touchdown, liftoff, or no beep at all. Click on the Beep button to  
select the appropriate option for your application. The default setting is no beep on touch  
(Beep off).

3M™ MicroTouch™ Software MT 7 User Guide  
Double-Click Speed (not available on Windows® CE or Linux®)  
Double-click speed defines how quickly you must touch the sensor for the system to  
interpret your actions as a double-click. Set the double-click speed in the slow to medium  
range for optimum performance with a touch sensor.  
Touch the globe twice to test the double-click speed and area settings. If the globe begins  
to spin, the sensor recognized your touch as a double-click.  
Note: Changing this setting will affect the double-click setting of the mouse.  
Double-Click Area (not available on Windows® CE or Linux®)  
Double-click area defines the space in which you must touch the sensor for the system to  
interpret your actions as a double-click. Set the double-click area in the medium to high  
range for optimum performance with a sensor.  
Touch the globe twice to test the double-click speed and area settings. If the globe begins  
to spin, the sensor recognized your touch as a double-click.  
Note: Changing this setting will affect the double-click setting of the mouse.  
Edge Adjustment Tab  
Once you calibrate the sensor, the cursor should be located directly beneath your finger  
when you touch the sensor. However, this may make it difficult to touch items at the very  
edges of the sensor. The Edge Adjustment tab enables you to define an offset area in  
which the cursor moves closer to the edges of the sensor so you can easily and more  
precisely select small items, such as single words, the Windows® Start button, check  
boxes, or radio buttons.  
For example, if you have a row of buttons along the left edge of your sensor, you may  
want to set an edge adjustment to enable users to easily activate these buttons. Because  
each edge is independent of the other, you only need to adjust the left margin to  
accommodate this row of buttons.

Linearization  
With certain controllers, you can perform a linearization to fine-tune your touch sensor.  
It should be performed only at the direction of 3M Touch Systems, Inc. Technical  
Support. Linearization consists of touching 25 targets on the display followed by 16  
additional points to determine specific point accuracy over the face of the display.  
The EX, and some RX series touch controllers support Linearization:  
Linearization Process  
To perform a 25-point linearization of the sensor:  
1. Make sure the video image is centered in the display area using the horizontal and  
vertical controls.  
2. Open the touch control panel and select the Controller tab.  
3. Click Linearize. This will bring up, one at a time, 25 linearization targets on the  
display.  
Note: If you press Escape or do not touch the sensor within 20 seconds, the system  
automatically cancels the linearization process with no change to the current settings.  
4. Touch the sensor and position your fingertip to completely cover the green target.  
When touching the target, make sure you:  
a. Face the display directly.  
b. Perform the linearization in the position (sitting or standing) you expect to use  
the sensor.  
c. Touch the target firmly and precisely with your fingertip. Be careful to keep your  
other fingers away from the sensor as you touch the target. Hold a steady touch  
over the target until you hear a beep or until the target turns red.  
5. Repeat these instructions until all 25 targets have been touched.  
A dialog will appear asking if you wish to “Test, Accept, or Cancel”.  
If you select Accept, then the new calibration settings are automatically accepted.  
If you select Cancel, the original settings will be restored without change.  
If you select Test, the 25 targets will now be replaced with a set of 16 targets used to  
verify the linearization performed in steps 1 through 5.  
These targets are yellow to begin with. If you successfully touch the target, it turns  
green. If you are off, it turns red and returns a percentage error number. If the  
linearization is not within acceptable tolerances, you should perform the linearization  
process again.  
Repeat the previous process for each of these targets. This process automatically  
returns to the control panel once complete. If you are using a pen stylus, repeat the  
linearization procedure with the pen.

3M™ MicroTouch™ Software MT 7 User Guide  
To test the accuracy of the linearization process, use the Draw Test program (found on  
the Tools Tab) to draw some lines on the screen. Check that they are smooth, straight,  
and thin. You do not want lines to look key stoned or curved.  
To exit this program at any time during the process, press Escape.  
Pen Overview (Pen Controller Only)  
From the Tools tab, click on Advanced Options and select Enable Pen/Finger Selection.  
These options are available only if your system has a pen controller. Pen Mode defines  
whether the touch sensor recognizes input from both a pen and a finger, from a pen only,  
or from a finger only. The default mode is Pen/Finger, which means that you can use  
either your finger or your pen to select options.  
Certain pens come with a button that can be used for right-clicks. To right-click, press  
and hold the button while you touch the sensor. After touching the sensor, quickly lift the  
pen and release the button.  
Note the Pen mode is immediately active. For example, if you select Pen Only, the  
system recognizes only the pen as a touch device. You cannot use your finger to make a  
selection. You can still use the mouse to select an option.  
The system saves the Pen mode so that the next time you power up the system, the  
selected pen mode is active.  
Pen and Finger Calibration  
On a pen system, you must calibrate the sensor twice, (once with your finger and once  
with the pen) if you are using Pen/Finger mode.  
Pen Modes  
Note: Changing the Pen mode setting can optimize the performance of the sensor. In  
Pen/Finger mode, the pen controller checks for input from either a pen or a finger. The  
pen controller always gives priority to the pen. If you are not currently using the pen for  
your touch application, use Finger Only mode for optimum system performance. If you  
are not currently using your finger for your touch application, use Pen Only mode for  
optimum system performance.  
Pen only mode—The system recognizes only pen touches on the sensor. The system  
ignores finger touches on the sensor.  
Finger only mode—The system recognizes only finger touches on the sensor. The  
system ignores pen touches on the sensor.  
Pen and finger mode—The system recognizes both pen and finger touches on the  
sensor. This mode is the default mode for Pen controllers. If the system detects both pen  
and finger touches at the same time, it gives the pen higher priority and acknowledges  
only the pen touches. This priority prevents accidental touches from your finger or hand  
being interpreted as input.

3M™ MicroTouch™ Software MT 7 User Guide  
29  
If you are using the pen and you lift the pen from the sensor, the system does not  
recognize finger touches until after a system-defined time delay. If your finger is on the  
sensor when the pen lifts off, the system ignores the finger until you lift off and touch the  
sensor again. For example, if you rest your hand on the sensor while you write with the  
pen, you can lift the pen and put it back again without your hand touch being  
acknowledged.  
Sensor Frequency  
Note: This option applies to capacitive EX series controllers.  
From the Tools tab, you can choose the Advanced Options button. From the Advanced  
Options dialog, select Enable Frequency Selection to activate this option on the  
Controller tab if you are using a capacitive EX-based controller.  
This option adjusts the operating frequency of the touch controller. In general, you will  
not need to adjust the Sensor Frequency. However, if you are experiencing problems  
with a jittery cursor, ragged lines, or random touch points, you may want to run the  
Enable Frequency Selection option.  
Use the Enable Frequency Selection option to test the available frequency settings and  
determine the best frequency. The range of frequency settings and the default setting  
depends on your touch controller. You can set a new operating frequency, and then check  
the performance of the touch sensor at that frequency setting.  
Be aware that if you choose Restore Factory Settings Controller from the Tools tab,  
you will change the Sensor Frequency to the factory default setting. You may need to  
redo the Sensor Frequency at this time.  
Sensor Frequency Procedure  
From the Tools tab, you can choose the Advanced Options button. From the Advanced  
Options dialog, select Enable Frequency Selection to activate this option on the  
controller tab if you are using a capacitive EX based controller.  
In the Sensor Frequency box, you will see a pull down list of several frequency options.  
In general, the highest possible frequency will provide the best results. Once you change  
the frequency, do not touch the sensor for approximately 30 seconds. Touch will return  
when the frequency has been changed. Test to see if you are satisfied.  
On a pen controller system, you have the option to change the frequency for both your  
finger and the pen if you are using Pen/Finger mode.  
Testing the Newly Selected Frequency  
Any time you adjust the Sensor Frequency you should test how the sensor is working and  
verify you are satisfied with the operation of the touch sensor.  
Test the sensor by touching in several places and sliding your finger around the sensor.  
The cursor should hold steady and smooth. If you see erratic or jittery cursor movement,  
readjust the Sensor Frequency.

3M™ MicroTouch™ Software MT 7 User Guide  
Adjust the frequency until your touch test produces acceptable results. A good test is to  
go to the Draw program and hold your finger steady on the sensor. If the resulting  
pattern is a crisp and clear single dot, you should have a good frequency.  
It is recommended that you recalibrate the touch sensor after you run the Sensor  
Frequency option.  
Controller ID  
Note: Changing this field will affect your multiple display setup.  
From the Tools tab, you can choose the Advanced Options button. From the Advanced  
Options dialog, select Enable Controller Identifier Selection to activate this option on the  
controller tab.  
If you do not have a multiple display setup, you do not need to use this field. Please refer  
to the Multiple Display section for more information.

Slow Draw Anomalies  
Using Draw mode can be slow on certain Windows® CE machines. For example,  
drawing a curve inside a draw application may produce ragged lines and the cursor may  
lag behind. The "IOPollDelay" parameter adjusts the behavior of draw mode. Adjusting  
the default value of this parameter may improve the behavior and appearance of the  
curve without affecting overall performance of the Windows® CE system. You can add  
this parameter to the system by editing the text file TwParams.reg found in  
C:\MT7_CE\x86. To add this parameter with a new default value insert the IOPollDelay  
line after the line below:  
[HKEY_LOCAL_MACHINE\Drivers\BuiltIn\TwTouch\Parameters]  
"IOPollDelay"=dword:1(value)  
A value between 1 and 20, such as 10 may work best for your particular application.  
After adding or modifying the value of this parameter, you need to rebuild the  
Windows® CE image and test the draw behavior.

3M™ MicroTouch™ Software MT 7 User Guide  
Before Driver Installation  
Know if your present Linux distribution will be compatible with the MT 7 driver.  
There are two terminal commands, which allow further preparation.  
uname -r  
X -version  
This will show the kernel version  
This will show the X Server Version  
Be aware that these commands are case sensitive. Here, the X must be uppercase.  
Note: MT 7.13 Build 3 only supports X Server releases of rev 1.10 and before.  
Installation Instructions  
The MT 7 for Linux® software is proprietary and not open source. The distribution is an  
executable program. Run this program using the following command lines where  
<version> is replaced with the current file version number:  
chmod a+x MT7.<version>.bin  
./MT7.<version>.bin  
You will then be asked to either accept or decline the license agreement. If you accept  
the agreement, the program produces a tar.gz file. Follow the remaining instructions to  
complete the installation process. For your convenience, the tar.gz file contains a copy of  
the license in the file License.txt.  
Discuss expanding tar.gz file- As mentioned above the MT 7 for Linux® package arrives  
as a tar.gz file. By default, the expanded package resides in the subdirectory twscreen.  
An install script installs the package. Installation includes creating the necessary init  
script, creating symbolic links in /usr/lib, making a X input module available,  
enabling USB hotplug for 3M™ MicroTouch™ devices, and creating a Remove script.  
General Instructions  
Before installing the package, read below to see if any of these special situations apply to  
you. If they do, you may need to edit the Install script.  
If you run the Install script and then discover errors, always run the Remove script to  
undo the installation. This removes possibly erroneous links into your system. Then edit  
the Install script, make the necessary changes, and install again.  
Preparation  
You must log in the Linux® operating system as the root user or use the sucommand to  
get super user access. On some systems, you may need to run in single user mode (run  
level 1 on some systems).  
The installation process requires write access to various system directories. By default,  
the directories are:  
/etc/udev or /etc/hotplug

/usr/lib/xorg/modules/input or  
/usr/X11R6/lib/modules/input  
/usr/lib  
/etc/init.d or /etc/rc.d  
/etc/X11/xinit/xinitrc.d or /etc/X11/xsessions.d  
If your system does not have these directories you will need to edit the Install script as  
discussed in the Other Options.  
After installation completes, the MT 7 for Linux® software no longer requires write  
access to these directories.  
Normal Installation  
Copy the tar.gz file into the directory where you want the package to reside, such as  
/etcor /opt. Issue the command tar xzf twscreen.<version>.tar.gz  
where <version>is a version number string of the tar.gz file. This creates the  
directory twscreen in the current directory. From there, go into the twscreen directory  
and issue the command ./Install. This script installs links in the Linux® and X  
Windows system for your sensor to work with your system.  
Installing on Write-Protected Systems  
The MT 7 for Linux® software requires access to a writeable directory for runtime and  
configuration data. By default, it uses a 'data' directory in the twscreen directory. If you  
need to have the package in a read-only directory, then decide on a writeable directory  
for the package to use. Edit the Install script and search for the line DataDir="".  
Change the definition of DataDir to the writeable directory. Save the changes and run the  
script. This creates the data directory where desired and creates a link in the package  
directory to the data directory.  
Other Options  
The MT 7 for Linux® software should install without other changes on most Linux®  
systems. However, if you have a customized directory structure or the installation script  
fails, you may need to edit the Install script and change one or more of the following  
script variables.  
ConvertAtRead  
The MT 7 for Linux® X input module translates raw touch data from the touch driver  
into the X Windows server display locations. Normally, the X server does this in two  
steps, first reading the raw input data from the input module and then having the module  
convert the coordinates as a second step. Some versions of the X.Org server code require  
that the input module return only converted coordinates in the single read step. This  
seems to apply only to early 1.4 versions of the server.  
If you use this server, or if touch is inaccurate after calibration, change the  
ConvertAtRead value to "true".  
To determine the version of your X server, issue the command X -version.

3M™ MicroTouch™ Software MT 7 User Guide  
HotplugDir  
Refer to the symbol UdevDirfor details.  
InitDir  
The MT 7 for Linux® software uses an init script, TWDrvStartup, to start and stop the  
touch driver. Normally, this runs at run level 5. If your init scripts are located in a  
directory other than /etc/init.d or /etc/rc.d, then set InitDirto the  
appropriate path.  
JavaBinDir  
Set this symbol to the path of the Java® runtime environment (JRE). This is needed to  
run the MT 7 Control Panel. If not set, the control panel will use the system’s default  
“java” program.  
LibDir  
The MT 7 for Linux® software uses several shared objects. The Install script links these  
into /usr/lib. If your system's libraries are elsewhere, change this variable to point to  
the correct path. This directory is mandatory and the software cannot run without its  
libraries in a common library directory.  
LSBDir  
An init script must adhere to a variety of conventions. Some conventions use files, such  
as function, in the script directory. The variable InitDir handles these cases.  
Some LSB-compliant systems require access to a file 'init-functions' normally found in  
/lib/lsb. If you have an LSB system and the init-functions file is not in /lib/lsb,  
you need to change the value of LSBDir.  
SEDir1 and SEDir2  
Some of the shared objects in the MT 7 for Linux® software require access to objects  
secured by SELinux. If the Install script detects SELinux, it assigns a security type to  
some shared objects. The script inspects the directories /usr/selinux/booleans  
and /selinux/booleansto determine if SELinux is active. If your SELinux is in a  
directory other than these, change the definition of one of these variables.  
SEGivePermission  
If the Install script detects SELinux, it assigns the security type texrel_shlib_tto  
some shared objects. If this is not appropriate for your system, edit the script and change  
this variable.  
UdevDir and HotplugDir  
The MT 7 for Linux® software supports hot plugging of USB controllers through either  
the udev or the hotplug systems. Older versions of Linux® used the hotplug system. The  
udev system replaced hotplug. It is on most current distributions. The Install script  
checks for udev support first. It assumes that the udev support files are in the directory  
/etc/udev/. If udev resides elsewhere, change the definition of UdevDir to the  
appropriate path.

3M™ MicroTouch™ Software MT 7 User Guide  
45  
The Install script assumes that the hotplug support files are in the directory  
/etc/hotplug/. If hotplug resides elsewhere, change the definition of HotplugDir to  
the appropriate path.  
If you want to disable hot plugging of USB controllers, change both UdevDir and  
HotplugDir to non-existent paths.  
XFree86Dir  
Refer to the symbol XorgDir for details.  
XinitDir and XinitSuffix  
The MT 7 for Linux® runs some background tasks needed for full support of some user  
interface features. The Install script uses an X init script to launch these tasks.  
The Install script automatically places the script 50MT7-xinit into the  
/etc/X11/xinit/xinitrc.dand /etc/X11/Xsession.ddirectories. If your  
distribution requires the script to go into a different location, supply a value to the  
XinitDir variable in the Install script.  
Some distributions require a suffix for these scripts. If needed, change the XinitSuffix  
value to the needed suffix. For example, if your distribution requires these scripts to have  
a .sh, change the XinitSuffix symbol to be .sh.  
XorgConf  
This symbol contains that path for xorg.conf file, normally /etc/X11/xorg.conf.  
MT 7 for Linux® must modify this file to register its drivers. If you use a different file,  
change the value of this symbol. If you do not use a configuration file, refer to 'Cannot  
find /etc/X11/xorg.conf'in the section 'Error Messages During Installation'.  
XorgDir and XFree86Dir  
The MT 7 for Linux® software uses an X input module to get touch data into the X  
Windows server. The Install script inspects the paths  
/usr/lib/xorg/modules/inputand /usr/X11R6/lib/modules/input.  
If your X input modules reside elsewhere, change the appropriate variable to the correct  
path.  
Error Messages During Installation  
This covers error messages generated by the Install script. Programs used by the script  
may generate their own messages. This section does not cover those messages.  
Note: Not all will be the same depending on which version you are running

3M™ MicroTouch™ Software MT 7 User Guide  
Cannot find needed libstdc++.so in /usr/lib  
Variations of the message may refer to other directories depending on the setting of the  
LibDir variable in the Install script. The installation script could not find the standard  
C++ shared objects. Confirm that the LibDir variable is set correctly. If so, you need to  
install the C++ shared objects or, if already present, create a symbolic link using the  
name libstdc++.soto the C++ shared object. You also need to create a symbolic  
link named libstdc++.so.5or libstdc++.so.6depending on which version of  
library is on your system.  
Cannot find shared memory support  
The MT 7 for Linux® software uses shared memory. Some older Linux® systems do not  
provide this support and the package will not run. Contact 3M Touch Systems for other  
options.  
Cannot find /etc/X11/xorg.conf  
Variations of this error may occur if a system uses a different xorg.conf file.  
MT 7 for Linux® uses an X input driver and requires this file so that the X server will  
load the driver. Since this file is optional, some systems do not have one present. If you  
use a different location for your xorg.conf file, edit the Install script and set the variable  
XorgConf.If is no xorg.conf file is present on the system there are two methods of  
creating one.  
The first method is to create XorgConfig. To do this, go to single user mode.  
Run the command ‘X-configure.’ This produces the file ~/xorg.conf. Copy  
this file to /etc/X11/xorg.conf. Finish by restarting your system.  
If the X Windows system restarts, you may proceed with the MT 7 installation.  
If X Windows does not start properly, get to a command prompt, it might be  
necessary to boot your system into single-user mode. Remove  
/etc/X11/xorg.confand restart X Windows. If this happens you will need  
edit the xorg.conf file before placing it into /etc/X11/.  
The second method is to edit the var-file. Copy the file  
/var/log/Xorg.0.log to another directory. Edit this file and look for a  
section where the X server says it is using a built-in configuration. Save just this  
section of the log file as a new xorg.conf file. Copy the new xorg.config file to  
/etc/X11/xorg.confand restart X Windows. Proceed with the MT 7  
installation.

Cannot install the init script  
The Install script tries to detect the presence of the chkconfig and update-rc.d utilities  
and the /etc/rc.d/rc.localscript. If it cannot find any of these, this message  
appears. If your system uses the chkcconfig or update-rc programs, make sure the PATH  
environment variable contains the path to where the programs reside. If rc.local is in  
another directory, edit the Install script and change the value of the InitDir variable. If  
your system uses some other system, you need to place the init script TWDrvStartup  
in the appropriate place. The Install script creates a copy where the MT 7 for Linux®  
package resides. You may need to edit the TWDrvStartup script to work with your  
system.  
Cannot install the X init script  
The Install script could not determine where to install the X init script needed by MT 7  
for Linux® to launch background tasks. Edit the Install script and set the XinitDir  
variable.  
Cannot install the X input module  
The Install script could not find the directory for the X input module. Confirm that the  
variable XorgDiror XFree86Diris set correctly in the Install script.  
Hot plugging of USB touch controllers is not supported  
The Install script cannot find the udev or hotplug support files. If you do not need hot  
plugging of USB controllers, ignore this message. Otherwise, edit the Install script and  
change the UdevDir or Hotplug variable to an appropriate value.  
Removing MT 7 For Linux  
In the installation directory, run the script Remove. This removes the data directories and  
disengages MT 7 for Linux® from the system. The files remain. You must manually  
remove the files from the twscreen directory.  
Troubleshooting The Init Script  
Due to the variety of methods of running init scripts, the Install script makes a best guess  
as to when the TWDrvStartup script should run. This guess is occasionally wrong.  
There are three critical considerations regarding the init script sequence.  
1. The USB file system must be operational before the TWDrvStartup script runs. If  
not, the driver does not service USB touch controllers. A symptom of this is  
calibration does not work.  
2. Any script that inspects serial ports must finish before the TWDrvStartup script runs.  
These programs can interfere with the driver's ability to detect and identify serial  
touch controllers. A symptom of this is touch or calibration not working.  
3M Touch Systems, Inc. Proprietary Information – 25695M  
Download from Www.Somanuals.com. All Manuals Search And Download.  
48  
3M™ MicroTouch™ Software MT 7 User Guide  
3. The TWDrvStartup script must complete before running the X server. The  
TWDrvStartup script modifies the X server configuration file (either xorg.cfgor  
xfree86.cfg). When the system shuts down, these files are restored to their  
original state. It also starts the touch driver, TwDriver. Scripts that launch the X  
server reference the programs xdm, gdm, or kdm. Symptoms of this are a lack of  
touch or possibly erratic touch with USB touch controllers.  
In each case, you need to rearrange the order of the init scripts to satisfy the requirements  
of the MT 7 for Linux® software. The method to do this is specific to your system's  
distribution.  
Troubleshooting Touch Behavior  
Many issues can affect touch.  
If you have no touch, it is likely that the X Windows server is starting before the MT 7  
for Linux® driver. First, inspect the X Windows configuration file, usually either  
/etc/X11/xorg.confor /etc/X11/xfree86.conf, and see if there is an entry  
for the "twxinput" driver. If this entry is present, inspect the X Windows server log file,  
usually either /var/log/Xorg.0.log or /var/log/XFree86.0.log, to see if  
the driver loaded without error. If the entry is missing or there is an error in the log file,  
refer to the section above, "Troubleshooting the Init Script".  
If the cursor reacts to a touch but does not appear under your finger, usually a simple  
calibration fixes the problem. If it does not, open a terminal window and type the  
command "X -version". If the first line of the output starts with X.Org X  
Server 1.4then you may need to enable the "ConvertAtRead" option. Review the  
section on "Other Options" under "Installation" for details.  
Running Touch Applications  
There are two touch applications that you can run to customize the touch system. These  
programs reside in the directory where you installed the package.  
1. The Calibration program aligns the sensor to the display's screen. You should run  
this program after installation or whenever adding a new sensor to the system. Run  
the program by running the TwCalib program.  
2. The Control Panel provides more features to customize your touch system. Run this  
program as needed by running the StartCP script.  
Note: This is a Java® program and runs with the JRE from Oracle®. If you experience  
problems running the Control Panel, download a JRE from www.oracle.com and install  
it.  
You also need to edit the StartCP script to provide the proper path to the JRE.

Calibration Messages Are Unreadable  
The Calibration program attempts to use a Helvetica font. If not found, it uses a  
relatively random font. This font may be unreadable.  
To override this behavior, set the symbol MT7FontSanSerif to a proper X Windows font  
name. To find a suitable font, use the xlsfontscommand or other suitable utility that  
lists the available fonts. In a command prompt, set the symbol, export it, and run the MT  
7 calibration utility TwCalib. Experiment with the value of MT7FontSansSerif until the  
calibration text is suitable. For example, if MT 7 for Linux® is in /etc/twscreen, a  
test sequence may be:  
MT7FontSansSerif="-*-utopia-*"  
export MT7FontSansSerif  
/etc/twscreen/TwCalib  
You can also test your font string with xlsf onts. After setting MT7FontSansSerif, issue  
the command xlsfonts -fn $MT7FontSansSerifto see what font, if any,  
matches.  
If you find a suitable font, change your system login script, such as  
/etc/profile.local, to set and export MT7FontSansSerif.

APPENDIX A  
Multiple Monitor Setup (Windows® Only)  
Overview  
The Multiple Monitor Manager enables you to set up multiple monitors with touch  
screens. You must intentionally load this utility during installation in order to configure  
multiple displays.  
To begin, ensure that you have unique identifiers for each controller. Check them from  
the Main tab – Controller ID. This field identifies the controller(s) attached to your  
system. If any controller ID value appears with a dot, (for example: USB00000001.1,  
USB00000001.2, etc.) you have two or more controllers with the same identifier. You  
must change these IDs before you run the multiple monitor manager.  
Changing the Controller ID  
To change the Controller ID:  
1. These values may be edited from the Tools tab Advanced Options menu and  
select “Enable controller identifier editing.” The resulting editable field appears on  
the Controller tab.  
2. Controller ID values can be as simple as 00000001, 00000002, and 00000003.  
3. Once the IDs are set, you are done. Exit the control panel.  
Setting Up Multiple Monitors  
To setup Multiple Monitors:  
1. Open the MT 7 Multiple Monitor Manager by clicking: Start Programs →  
MicroTouch MT 7 MultiMonitor Manager.

2. To associate or link a sensor to a particular monitor, select that monitor and simply  
touch a touch screen. Note that the displays have colored frames that will blink when  
selected and match the touch screen frame once they have been linked.  
3. Once you have linked your touch screen to monitors, you may choose to Save your  
changes, Cancel your changes or simply Start Over.  
In the screen below, none of the touch screens or monitors has been linked.  
In the following example, Touch Screen A has been linked to Monitor 1 and Touch  
Screen B has been linked to Monitor 2. Note the color similarities once a Touch Screen  
and a Monitor have been associated.

APPENDIX B  
Troubleshooting the Touch System  
Overview  
This chapter provides tips and strategies for problems you may encounter with the touch  
system either during installation or normal use.  
3M Touch Systems, Inc. is committed to helping you get the most out of your touch  
system. If you are unable to resolve your problem using the troubleshooting information  
contained in this chapter, contact 3M Touch Systems, Inc. Technical Support. For  
information on how to reach technical support in your area, refer to the 3M Touch  
Systems, Inc. Support Services section at the beginning of this guide.  
If you are experiencing problems with the sensor, check that all cables are connected  
properly and restart your system.  
Verify that any previously loaded hardware and/or software installed in the same serial  
port as your sensor has been uninstalled. Even though the hardware has been  
disconnected, the software can still claim the port. Ensure that all components are  
completely removed from the system files.  
To correct the communication settings in a Windows® system, use the Windows®  
Hardware Conflict Troubleshooter from Windows® Help.  
Note: For specific troubleshooting information for Linux® systems, refer to Chapter 5.  
Other Serial Devices Do Not Work  
EX serial and SX pen controllers do not support plug and play functionality used by the  
Windows® operating system. MT 7 must search for these devices and that process can  
interfere with other serial devices on the same system.

3M™ MicroTouch™ Software MT 7 User Guide  
If you do not have either of these controllers, rerun setup, select the upgrade option and  
under Controller Support deselect EX and SX pen controllers. Complete the software  
setup and reboot your system.  
Important Note: Editing registry values may alter the performance of your system or  
render it inoperable. Create a backup of your Windows® system registry file before  
making any changes to these files. Refer to Microsoft Windows® Help for instructions  
on handling registry files.  
If you do have either of these controllers, you will need to edit the registry file. In  
REGEDIT, browse to  
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\TwTouch\Parameters.  
Create a new string value called SerialPortSearch. Assign a value to the set of COM  
ports with serial controllers (i.e., “COM1,COM3”). When complete, reboot your system.  
Multiple Display Support  
This release of the MT 7 control panel supports multiple displays. When installing MT 7,  
you must select the Multiple Monitor Manager tool to enable this function.  
Cursor Does Not Reach Edges of Display  
Try calibrating the touch sensor. When calibrating the sensor, be sure you touch the  
center of each target firmly and precisely. If additional tuning is necessary, use the Edge  
Adjustment Tab to enable greater ability to touch into corners and edges of the sensor.  
Cursor is Jittery  
You need to adjust the Sensor Frequency. Choose Sensor Frequency from the Controller  
tab. Any time you adjust the frequency you should test how the sensor is working and  
verify you are satisfied with the operation of the sensor.  
Note: This option applies to capacitive EX series controllers.  
Cursor Jumps or Bounces Suddenly Across the Display  
You are most likely touching the sensor in more than one spot at the same time. Be sure  
to point and touch with one finger only. Keep your other fingers away from the touch  
sensor. Do not rest your other hand on the display or bezel at the same time.  
Double-Click Doesn't Work (not available on Windows® CE or Linux®)  
Use the Touch Settings tab to adjust the double-click speed and area. The double-click  
speed defines how quickly you must touch the sensor for the system to interpret your  
actions as a double-click. Set the double-click speed in the slow to medium range for  
optimum performance with a sensor.

The double-click area defines the space in which you must touch the sensor for the  
system to interpret your actions as a double-click. Set the double-click area in the  
medium to high range for optimum performance with a sensor.  
Click on the globe to test the double-click speed and area settings. If globe begins to  
spin, the sensor recognized your touch as a double-click.  
Note: Changing this setting will affect the double-click setting of the mouse.  
Drawing Lines Are Not Straight and Smooth  
Contact 3M Touch Systems, Inc. Technical Support for assistance performing a manual  
linearization.  
Find Sensor (for Serial Plug & Play Controllers)  
Note: This option applies to Windows® only.  
1. Do a Find New Hardware from Windows® control panel.  
2. Reinstall MT 7 using the Custom installation option and make sure you are choosing  
the correct controller support.  
3. Reboot your system and try again. If the problem persists, call 3M Touch Systems,  
Inc. Technical Support.  
Note: Verify that any previously loaded hardware and/or software installed in the same  
serial port as your sensor has been uninstalled. Even though the hardware has been  
disconnected, the software can still claim the port. Ensure that all components are  
completely removed from the system files.  
Touch Is Not Working  
If the controller information box on the Main Tab is grayed out and contains no  
information, the sensor is not communicating with the controller. If MT 7 does not find  
the sensor, check that the sensor is connected properly.  
If you are experiencing problems with the sensor, check that all cables are connected  
properly and restart your system.  
To correct the communication settings in a Windows® system, use the Windows®  
Hardware Conflict Troubleshooter from Windows® Help.  
Note: Verify that any previously loaded hardware and/or software installed in the same  
serial port as your sensor has been uninstalled. Even though the hardware has been  
disconnected, the software can still claim the port. Ensure that all components are  
completely removed from the system files.

3M™ MicroTouch™ Software MT 7 User Guide  
Check the following items:  
1. Make sure the touch controller is connected to the correct port.  
2. Review the installation procedures and verify all hardware is properly connected.  
Check the serial port and sensor cable connections. Check that the sensor and  
controller cables do not have any kinks and that connector pins are not bent.  
3. Reset the sensor and its controller. Turn off both the computer and the display, wait a  
few minutes, and then turn on each device again.  
Touch Driver Did Not Load  
Check Windows® device manager under mice and pointing devices to see if the  
MicroTouch drive is loaded and running without errors (under system devices for the  
MicroTouch bus driver (used only for EX serial sensors)).  
If these are missing, run Installdriver.bat inside WINNT\Program Files\  
MicroTouch\MT7 to reload the driver.  
If this does not work then run Removedriver.bat, reboot then rerun Installdriver.bat.  
Right-click Tool Buttons Are Swapped  
Using the control panel, it is possible to change which button on a mouse generates the  
"left" and "right" clicks. This feature allows left-handed people to use their index finger  
to produce a left click. This setting causes the touch driver to also reverse the meaning of  
a touch. Normally, a touch produces a left click. With the changed setting above, a touch  
starts producing a right-click.  
To address this, edit the file "TwFactory.cfg" in the MT 7 for Windows™ software  
directory. If this file is empty, add in the text:  
<Touch>  
</Touch>  
Between these two lines, add a new line:  
SwapMouseButtons=1  
Save the file.  
Open a command line window and set your working directory to the MT 7 for  
Windows™ directory. Issue the command: TwCfgUtil /u TwFactory.cfg  
At this point, your touches start producing the desired left-clicks.  
If your system supports multiple users, you may need to create separate files, such as  
TwLeft.cfg and TwRight.cfg. In TwLeft.cfg, set SwapMouseButtons to 1 and in  
TwRight.cfg, set SwapMouseButtons to 0.  
Add the above TwCfgUtil to each user's Startup menu or login script, using TwLeft.cfg  
or TwRight.cfg as appropriate.
