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 options available with LCDs. LCD monitors consist
primarily of an LCD, Video Board and a Back Light video. The LCD
determines to a large extent the 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]
display. The displayed picture would be in the center 1/3 of the LCD. With the introduction of the
scaling engine. The converter will mathematically recalculate the 640x480 to 1024x768. This may sound
simple but it is in fact a complex algorithm that adjusts for different aspect ratios and pixel alignment,
essentially smoothing text and graphics to produce a picture that is pleasant to the eye.
All Vartech displays from 12.1” (800x600) to 23.1 (1600x1200) incorporate scaling engines in the
converter card.

2.2 Unpacking and setting up your display
Your LCD monitor package will consist of the components listed below. Open shipping container
and lay all components on a flat clean surface.
⇒ VT170R or VT170P, or VT170C or VT170W LCD Monitor
⇒ 5 ft Video Cable
⇒ Chassis model only has a +12V power connection. (115/220VAC Power Supply is optional)
⇒ 10-32 Mounting Hardware. (For use with Panel Mount only)
⇒ 6 ft RS232 Touch Interface Cable (Optional when touch is installed)
⇒ CD ROM with Touch Screen Drivers (Optional when touch is installed)
⇒ Users Manual
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 customer
supplied +12VDC source to the 12V connection on the rear (Chassis model only) . All other
models have a integrated 115/220VAC power supply.
3. Once the +12V or 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 Input Signal”,
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:
(a) The resolution is to high or low for the LCD.
(b) 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.
(c) The power source is incorrect.
(d)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.

Mounting Instructions
Mounting instructions for chassis mount
The chassis mount contains a simple frame with mounting holes. Traditionally captive hard-
ware would be used to secure the display against a panel with the proper hole size based on
the mechanical drawing. The chassis display is supplied with a piece of Plexiglas material
sealed to the front for protection. If the display is equipped with a touch screen, the touch
screen takes the place of the Plexiglas for protection of the LCD.
The unit is normally supplied for +12V operation, however it is available with a 115/220VAC
supply.

Panel Mounting Cutout
2. If access to the side of the monitor is not available following installation, attach the power
and video cables to the side of the monitor at this time.
3. Install the monitor in the prepared cutout.
4. Install the lock nuts and washers, supplied with the monitor, behind the holes running along
the sides and top/bottom of the cutout in the panel. Extra lock nuts and washers are provided.
Note: Use #10-32 nuts for mounting.
5. Tighten all mounting nuts evenly to a torque of 24 inch-pounds.
ATTENTION: Mounting nuts must be tightened to a torque of 24 inch-pounds to provide
panel seal and avoid potential damage. Vartech Displays assumes no responsibility for water or
chemical damage to the monitor or other equipment within the enclosure due to
improper installation.
6. Attach the power and video cables to the side of the monitor if you
have not already done so. .

Rack Mounting Procedure
1. Carefully remove the monitor from its packaging.
2. Locate holes in the cabinet front mounting rails corresponding to the holes in the monitor
front panel. Install clip nuts behind the holes in the rails if threaded rails are not provided.
Note: The mounting rails that run vertically along the inside edges of the front opening of an
EIA rack cabinet can be of two types:
· “Wide” rails have holes spaced 0.5"(12.7 mm) and 1.25"(31.8 mm) on centers, in a repeating
pattern. Wide rails are prevalent in Europe. · “Universal” rails have holes spaced 0.5"(12.7 mm),
0.625"(31.8 mm), and 0.625"(31.8 mm) on centers, in a repeating pattern. Thus, the universal
rails have a hole pattern that contains the wide pattern but provides an additional hole at the
midpoint of the pattern. Universal rails are most prevalent in the US.
3. Install the monitor into the cabinet from the front.
4. Secure the monitor chassis to the cabinet by installing panel mounting screws through the
holes in the monitor front panel and into the rails behind.

Touch Screen

Section
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.
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.

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 connec-
tor 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.
5.3 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.
5.4 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 pro-
vides the serial interface for the touch controller.
Interconnecting wiring to the host serial port connection is shown in the
following table.
