Installing the Serial Touch Driver  
Installing the Serial Touch Driver for Windows XP,  
Windows 2000, Me, 95/98 and NT 4.0  
NOTE: For Windows 2000 and NT 4.0 you must have administrator access rights to install  
the driver.  
To install Windows 2000 and Windows XP, you must use the "update driver" method; you will  
not find a setup.exe file within the download.  
1. Insert the Elo CD-ROM in your computer's CD-ROM drive.  
2. If the AutoStart feature for your CD-ROM drive is active, the system automatically detects  
the CD and starts the setup program.  
3. Follow the directions on the screen to complete the driver setup for your version of Windows.  
4. If the AutoStart feature is not active:  
a. Click Start > Run.  
b. Click the Browse button to locate the EloCd.exe program on the CD-ROM.  
c. Click Open, then OK to run EloCd.exe.  
5. Follow the directions on the screen to complete the driver setup for your version of Windows.

Installing the Serial Touch Driver for MS-DOS and Windows 3.1  
You must have a DOS mouse driver (MOUSE.COM) installed for your mouse if you wish to  
continue using your mouse along with your touchmonitor inDOS.  
To install Windows 3.x and MS-DOS from Windows 95/98, follow the directions below:  
1. Insert the CD-ROM in your computer’s CD-ROM drive.  
2. From DOS, type d:\EloDos_W31 to change to the correct directory on the CD-ROM (your  
CD-ROM drive may be mapped to a different drive letter).  
3. Type INSTALL and press Enter to start the installation.  
4. Align the touchscreen.  
You must have already completed Steps 1 and 2 before proceeding.  
To run the INSTALL program:  
1. Type INSTALL at the DOS prompt in the directory containing the driver install files.  
2. INSTALL asks you to select the software to install. Then choose d:\EloDos_W31 from the  
displayed list.  
3. INSTALL also asks you for the paths to use during installation, or you may use its defaults.  
INSTALL creates directories as necessary, and warns you if they exist.  
If you are updating your software, you may wish to specify the paths containing the earlier versions,  
and overwrite the obsolete files. All executable programs are upward compatible. For a list of  
differences from each previous version of the drivers, be sure to select "Differences from Previous  
Versions" during the installation process.  
INSTALLupdates yourAUTOEXEC.BAT file with the drivers you select. INSTALLmakes a copy  
of your originalAUTOEXEC.BAT file, calledAUTOEXEC.OLD. If you already have Elo driver  
commands in your AUTOEXEC.BAT file, they will be commented out.  
When INSTALL is finished, it leaves a file called GO.BAT in the subdirectory you specified. GO  
loads the touchscreen driver, runs the calibration program ELOCALIB, and gives you some final  
instructions.  
If you are using Windows 3.1, you will also calibrate the touchscreen within Windows 3.1 with the  
Touchscreen Control Panel.

OPERATION  
About Touchmonitor Adjustments  
Your touchmonitor will not likely require adjustment. However, variations in video output and  
application may require adjustments to your touchmonitor to optimize the quality of the display.  
For best performance, your touchmonitor should be operating in native resolution, 1440 x 900  
at 60 Hz. Use the Display control panel in Windows to choose 1440 x 900 resolution.  
Operating in other resolutions will degrade video performance. For further information, please  
refer to Appendix A, page A-25.  
All control adjustments are automatically memorized. This feature saves you from having to reset  
your choices every time you unplug or power your touchmonitor off and on. If there is a power  
failure, your touchmonitor settings will not default to the factory specifications.

Preset Modes  
To reduce the need for adjustment for different modes, the monitor has default setting modes that  
are most commonly used as given in the table below. If any of these display modes are detected, the  
monitor automatically adjusts the picture size and centering. When no mode is matched, the user can  
store their preferred modes in the user modes. The monitor is capable of storing up to 7 user modes.  
The only condition to store as a user mode is the new display information must have 1 KHz differ-  
ence for horizontal frequency or 1 Hz for vertical frequency or the sync signal polarities are differ-  
ent from the default modes.

NATIVE RESOLUTION  
The native resolution of a monitor is the resolution level at which the LCD panel is designed to  
perform best. For the 1938L LCD touchmonitor, the native resolution is 1440 x 900. In almost  
all cases, screen images look best when viewed at their native resolution.

Displays in Native Resolution  
The native resolution of an LCD is the actual number of pixels horizontally in the LCD by the  
number of pixels vertically in the LCD. LCD resolution is usually represented by the following  
symbols:  
VGA  
640 x 480  
800 x 600

1280 x 1024

WSXGA+ 1680 x 1050  
A-24 User Guide  
 
As an example, a WXGA+ resolution LCD panel has 1440 pixels horizontally by 900 pixels  
vertically. Input video is also represented by the same terms. WXGA input video has a format of  
1440 pixels horizontally by 900 pixels vertically. When the input pixels contained in the video  
input format match the native resolution of the panel, there is a one to one correspondence of  
mapping of input video pixels to LCD pixels. As an example, the pixel in column 45 and row 26  
of the input video is in column 45 and row 26 of the LCD. For the case when the input video is at  
a lower resolution than the native resolution of the LCD, the direct correspondence between the  
video pixels and the LCD pixels is lost. The LCD controller can compute the correspondence  
between video pixels and LCD pixels using algorithms contained on its controller. The accuracy  
of the algorithms determines the fidelity of conversion of video pixels to LCD pixels. Poor  
fidelity conversion can result in artifacts in the LCD displayed image such as varying width  
characters.

REGULATORY INFORMATION  
I. Electrical Safety Information:  
A) Compliance is required with respect to the voltage, frequency, and current requirements  
indicated on the manufacturer’s label. Connection to a different power source than those  
specified herein will likely result in improper operation, damage to the equipment or pose a  
firehazard if the limitations are not followed.  
B) There are no operator serviceable parts inside this equipment. There are hazardous  
voltages generated by this equipment which constitute a safety hazard. Service should be  
provided only by a qualified service technician.  
C) This equipment is provided with a detachable power cord which has an integral safety  
ground wire intended for connection to a grounded safety outlet.  
1) Do not substitute the cord with other than the provided approved type. Under no  
circumstances use an adapter plug to connect to a 2-wire outlet as this will defeat the  
continuity of the grounding wire.  
2) The equipment requires the use of the ground wire as a part of the safety certification,  
modification or misuse can provide a shock hazard that can result in serious injury or  
death.  
3) Contact a qualified electrician or the manufacturer if there are questions about the  
installation prior to connecting the equipment to mains power.

and Standards:  
This equipment has been tested to the requirements for the CE Mark as required by EMC  
Directive 89/336/EEC indicated in European Standard EN 55022 Class B and the Low Volt  
age Directive 73/23/EEC as indicated in European Standard EN 60950.  
D) General Information to all Users: This equipment generates, uses and can radiate radio  
frequency energy. If not installed and used according to this manual the equipment may cause  
interference with radio and television communications. There is, however, no guarantee that  
interference will not occur in any particular installation due to site-specific factors.  
1) In order to meet emission and immunity requirements, the user must observe the following:  
a) Use only the provided I/O cables to connect this digital device with any computer.  
b) To ensure compliance, use only the provided manufacturer’s approved line cord.  
c) The user is cautioned that changes or modifications to the equipment not expressly  
approved by the party responsible for compliance could void the user’s authority to operate  
the equipment.  
2) If this equipment appears to cause interference with radio or television reception, or any other  
device:  
a) Verify as an emission source by turning the equipment off and on.  
b) If you determine that this equipment is causing the interference, try to correct the  
interference by using one or more of the following measures:  
i) Move the digital device away from the affected receiver.  
ii) Reposition (turn) the digital device with respect to the affected receiver.  
iii) Reorient the affected receiver’s antenna.  
iv) Plug the digital device into a different AC outlet so the digital device and the  
receiver are on different branch circuits.  
v) Disconnect and remove any I/O cables that the digital device does not use.  
(Unterminated I/O cables are a potential source of high RF emission levels.)  
vi) Plug the digital device into only a grounded outlet receptacle. Do not use AC  
adapter plugs. (Removing or cutting the line cord ground may increase RF emission  
levels and may also present a lethal shock hazard to the user.)
