About LCD Monitors
What you gain by using an LCD monitor in your industrial controls
are the future of display technology. CRTs, although they have dropped in
cost significantly, do not offer the performance, reliability, and mounting

viewing angle, brightness and contrast. Beyond that it is the function of the video board which converts
the analog RGB (Red, Green, Blue) signals from a standard video card to a high quality, digital RGB that
the LCD can display.
Recently the video card has taken on a new role. It is the responsibility of this device to “scale” a
particular video resolution to the “native” resolution of the LCD. Simply, consider that a computer is
putting out a VGA [640x480] resolution signal, yet the LCD that is connected is an XGA [1024x768]

Page 5
On Installation
Do not allow anything to rest upon or roll over the power cord, and do not place
the display where the power cord is subject to damage.
Do not use this display near water such as near a sink, in a wet location where there is standing
water. Displays are provided with ventilation openings in the cabinet to allow the release of heat
generated during operation. If these openings are blocked, built-up heat can cause failures which
may result in a fire hazard.
Therefore, NEVER:
♦ Block any ventilation slots.
♦ Place the display in a built-in enclosure unless proper ventilation is provided.
♦ Cover the openings with cloth or other material.
♦ Place the display near or over a heat source.
Do not rub or strike the Active Matrix LCD with anything hard as this may scratch,
mar, or damage the Active Matrix LCD permanently.
Do not press the LCD screen with your finger for a long time as this may cause
some afterimages.
Some dot defects may appear as Red, Green or Blue spots on the screen.
However, this will have no impact or effect on the display performance.
If possible, use the recommended resolution to obtain the best image quality for
your LCD display. If used under any mode except the recommended resolution,
some scaled or processed images may appear on the screen. However, this is
characteristic of the fixed-resolution LCD panel.
On Cleaning
Unplug the display before cleaning the face of the display screen. Use a 50/50 mix of Isopropyl
alcohol and water. Apply with a slightly damp (not wet) lint free cloth. Do not use an aerosol directly
on the display screen because over-spraying may cause electrical shock.
On Repacking
Do not throw away the carton and packing materials. They make an ideal container in which to
transport the unit. When shipping the unit to another location, repack it in its original material.

Connecting the Display
1. Connect all cables to the computer first. This would include the VGA cable and the optional RS
232 serial touch screen connection.
2. After connecting the cables between the LCD monitor and the computer, plug the power cord into
the 115/220VAC power outlet if using using the optional AC to 12VDC power supply.
3. Once the 115/220VAC connection is made, the display is active.
4. If your computer was off, turn on your computer.
5. Your display should now operate as a normal computer display showing your windows or
whatever video is being sent to the flat panel.
Note:
If for any reason the display goes blank and gives an “out of Range” or “No Sync”, your computer
or video source is putting out a signal that is out of range of the LCD’s video board. If this happens,
reboot the computer or video source and make sure you are inputting the correct signal. If the display doesn’t work properly, it may be because:
The resolution is to high or low for the LCD.
(a) The refresh rate is set to high. Refresh on an LCD is different than a CRT. Set the refresh to
60Hz. CRT’s need a high refresh rate to avoid flicker. The refresh rate has no impact on LCD’s.
(b) The power source is incorrect.
(c) The unit is malfunctioning. If you believe this to be true, disconnect the video cable from the rear
of the LCD and connect to a known good computer CRT display. If the computer display is
working satisfactory and the video is within the appropriate range, then contact VarTech
Customer service for a RMA number.

Touch Screen Introduction
Touch screen interfaces have become the standard interface in the past 5 years. They are,
rugged, reliable, extremely flexible and easier than ever to implement! Over 90% of the
display packages Vartech Systems builds are touch screen systems. If you are uncertain
about using a touch screen, or are having difficulty, please call us. The universal acceptance
of the Windows GUI [Graphical User Interface] along with the extensive use of a mouse
interface has significantly accelerated the use of touch interface. Basically think of your touch
screen as if it were a mouse.
4.2
Touch Screen Definition
Quite simply, Vartech Systems touch systems are a mouse emulator. By installing a software
driver and connecting to a serial port, the touch screen will support all the primary mouse
functions:
Our standard touch screen interface, is a high resolution analog resistive. Following is a quick
explanation of what all this means.
High Resolution: The touch screen resolution is 400 ppi [points per inch]
Analog Resistive: The actual touch glass is an analog device. Meaning there is a very low
voltage applied to the X and Y axis of the touch screen. This current is applied to ITO [Iridium
Tin Oxide] that is sputtered onto a polyester membrane. When you touch the screen you are
changing the resistance on both the X and Y axis, producing an analog value that references
a particular location.
This type of screen can be activated with a gloved finger or mechanical stylus.
The touch screen itself is connected to electronics that provide the Analog to Digital
conversion. When the screen is touched, the electronics convert the analog voltage to a
digital value and add a “Mouse Click”, then sends the data to the serial port that the driver is
loaded to. When the touch is released the new XY location is sent along with a “Mouse Up
Click”.
This system requires no special software knowledge, and can be installed and set up in
minutes. The following section gives a detailed explanation of the software setup and
configuration.
Since the touch screen interface is RS-232, the recommend maximum distance from the PC
is 50 feet. In reality, every application is different. The touch driver default baud rate is 9600,
and we have tested the driver and interface with good quality cables to 50 feet. With RS-232
line drivers this can be extended almost indefinitely.
11

Touch Screen Definition Cont.
Connecting the touch screen
1. Make sure all optional cables have been received.
2. Connect one end of the 6 foot touch screen serial cable to the touch screen port D9 connector on the side of the monitor.
3. Connect the other end to any communications port on the host computer.
4. Tighten the captive screws on the cable connector to secure it.
4.3
Touch Screen Serial Interface
All touch controllers are configured by default to provide serial communications at 9600 baud, 8 data
bits, 1 stop bit, no parity. For Vartech flat panels equipped with touch screens, a serial
communications cable is required. This 6 foot cable comes with the unit in the accessory kit.
The cable is a straight wired serial (RS-232) cable with a male DE-9 D-shell connector on the
monitor end. The cable provides a communications channel between the touch screen
controller, which is mounted inside the monitor, and an RS-232 serial port on the host computer.
Because the touch controller obtains power from the monitor's power supply, no external touch power
connections are necessary.
Software supplied with the touch screen must be loaded on the host computer to handle
communications with the touch controller over the channel.
Because the touch screen emulates a mouse, there may be compatibility issues involving how the
touch screen emulates mouse buttons, especially multiple buttons.
4.4
Setting up the Touch Screen Interface
Enabling the Touch Screen Interface
The Flat Panel Monitor provides a female DE-9 connector for the touch interface.
This connector provides the serial interface for the touch controller.
Interconnecting wiring to the host serial port connection is shown in the following table.

Troubleshooting Tips
Troubleshooting Tips
• The signal cable should be properly connected to the display
card and computer.
• Try disconnecting the video cable from the display and
connecting to a CRT display if available to confirm the
presence of proper video.
• Make sure power is connected to the proper DC or AC
source.
• Make sure the resolution mode is supported by the display
and check settings of the display card.
• Confirm that the video cable is not defective.
Image persistence occurs when a ghost of an image remains on
the screen after the monitor has been turned off. Unlike a CRT
monitor, an LCD monitor’s image persistence is not permanent.
To erase an image ghost, turn the monitor off for as long as the
image was displayed. If the image was on for one hour and the
ghost of the image remains, the display should be turned off for
one hour to erase the image. To avoid this problem, use a screen
saver.

Cleaning
Occasionally clean the display panel and cabinet with a soft cloth dampened (not
soaked) with a mild (non-abrasive) glass cleaner. Keep turning a fresh side of the
cloth toward the screen surface to avoid scratching it with accumulated grit.
Do not use paper products as they may scratch the surface. To minimize the risk of
abrasion, allow the screen to stand dry.
Note: The solvent (a 50/50 mixture isopropyl alcohol and water) should be applied
only to the cloth, and not directly on the monitor screen.
Special care should be taken when cleaning a touch screen or polycarbonate shield
that is installed over the screen. Abrasive and certain chemical cleaners can easily
damage the surface.
Never use alcoholic or ammoniac cleaners to clean the polycarbonate shield or a
touch screen.
Replacing a Line Cord
To avoid shock and fire hazards, the monitor’s power cord should be replaced if the
insulation becomes broken or if it develops a loose internal connection.
Other Maintenance
Qualified service personnel should perform all maintenance, except for
the power cord replacement described above.
