Chapter 1
Outline
The ZM-94T (TFT color LCD) and ZM-95T (TFT color LCD with touch panel) liquid crystal terminals are
flat panel displays, one with a touch panel (ZM-95T). These LCD terminals can be used in place of the
CRT monitors normally used in personal computers. The panel mount construction allows them to be
installed into any type of equipment.
The viewable display screen size is 12.1 inches (diagonal) SVGA with a resolution of 800 x 600 pixels.
They receive RGB signals from a personal computer or a board-type computer. The display can be
adjusted.

Safety Precautions
Please note the following considerations for using and storing the ZM-94T/95T (hereafter referred to as
"the monitor").
■ High voltage
· Do not remove the rear cover unless you are replacing the backlight. Inside the rear cover are high
voltage parts used to backlight the LCD screen. It is quite dangerous if you touch them.
■ Cautions for static electricity
· Prior to touching the monitor, discharge any static electricity in your body by touching a grounded
metal part.
Significant amounts of static electricity may build up on the human body in extremely dry conditions.
The monitor employs an open frame system, which is convenient for mounting the display on a
panel. For this reason, some sections of the monitor have exposed electric circuits. Touching any of
these parts with your body may damage them due to static electricity built up in your body.
■ Wiring
· Be careful not to reverse the polarity on the 12 VDC input connector on the this model. If the polarity
is reversed, the monitor may be damaged.
· The 12 VDC power lines should not be longer than 50 cm, in order to prevent an unreasonable
voltage drop.
· Keep the RGB input lines and the 12 VDC power supply lines away from high voltage or strong
current lines such as commercial power lines separated by 20 cm or more.
· The distance between the touch panel and the computer should be 15 m or less (RS-232C serial
communicatio specifications).
■ 12 VDC external power
· Make sure to use a dedicated 12 VDC power supply (an insulated type able to supply the monitor
with sufficient current). Sharing a single power supply with an other device may adversely affect the
performance of the monitor.
· The SG and FG lines are connected inside the monitor. Therefore, if the 12 V line (positive side) is
accidentally grounded, the monitor may be damaged by excessive current flow. To ground the
monitor, make sure to ground it to the negative power line.
■ Liquid crystal panels
· LCD panels are produced using extremely precise technology. 99.99% or more of their pixels are
functional when shipped. However, due to the inherent characteristics of LCD panels, you may
notice that some panels may have dark or stuck pixels. Even so, they should be less than 0.01% of
total.
■ Video input signal
· When the monitor is driven by analog signals, some noise may be seen at specific levels of graduated color.
· The monitor cannot be connected to a computer that is operated at other than the specified dot clock
frequencies.
· When the computer signals (see the timing chart) are significantly different from the signals recommended on page 23, the monitor cannot automatically adjust the standard image position.
-2-
■ Installation
Avoid storing or using the ZM-94T/95T in the following conditions:
· Direct sunlight or ambient temperature extremes outside the range of 0 to 50°C
· Relative humidity exceeding the range of 35 to 85% RH, or sudden temperature changes which may
cause condensation.
· Corrosive or flammable gases.
· Locations subject to vibration and shock.
■ Installation
· Fasten the retaining screws in this monitor.
· Tighten the screens on the RGB cable’s connector and the 12 VDC terminal block screws.
· In order to prevent excess temperature build up inside the monitor, do not block the ventilation holes
on the side of the monitor.
· In the case of the ZM-95T, do not block the hole on the lower right side of the touch panel (marked
with an * on page 5). If it is blocked, the operation of the ZM-95T may be affected adversely.
■ Cleaning
· Never use any kind of solvent on the screen surface as it may warp or change color.
· Do not allow any liquid or small metal objects (such as trimmings from copper wires) to get inside
the monitor. Using a monitor which is contaminated is quite dangerous and may cause the monitor
to malfunction.
■ Operation
· Do not use excessive force when handling the monitor switches and connectors.
■ Touch panel
· The touch panel on the monitor is made of glass. Be careful not to place any stress on the touch
panel during installation. If it is stressed, the touch panel may be broken easily.
· The touch panel surface can be scratched easily. Do not hit or draw on the surface using any
pointed object such as a ball point pen. Otherwise it may cause a malfunction. We recommend using
a touch pad operation pen, like the one shown below:
R3
φ6
Hard 60゜silicone rubber
· Remove the protective sheet covering the touch panel before use it.

[3] How to replace the backlight
The backlight used in the ZM-94T/95T will wear out. When you have to replace the backlight because it
has worn out, make sure to turn OFF the power to the ZM-94T/95T. Then, replace it as described in the
procedures below.
Note: Since the backlight may have a residual high voltage charge, touching it may give you an electrical
shock. Replace both backlights at the same time.
(1) Remove the 4 screws securing the rear cover on the ZM-94T/95T and then remove the rear cover.
(See pages 4 and 5.)
(2) Remove the connectors on the backlights from the ZM-94T/95T main housing.

· Make sure to use a dedicated 12 VDC power supply (insulated type able to supply the
monitor with 2A or more). Sharing a single power supply with other equipment may adversely affect the performance of the monitor.
· Be careful not to reverse the polarity of the 12 VDC power input on this model. Otherwise,
this monitor may be damaged.
· The length of the 12 VDC power lines should not be more than 50 cm, in order to prevent an
excessive voltage drop.
· Keep the RGB input lines and 12 VDC lines away from high voltage or strong current lines,
such as power lines. (Separate by 20 cm or more.)
· The SG and FG lines are connected inside the monitor. Therefore, if the 12 V line (positive
side) is grounded (figure 1 below), the monitor may be damaged by excessive current flow.
To ground the monitor, make sure to ground it to the negative power line (figure 2 below).

• Normally, the data values sent will be between 0 and 1023. However, due to fluctuations in
the data from the touch panel, it must be corrected at the host computer. (Resolution: 1024 (X)
× 1024 (Y))
• It is possible that data exceeding the range given above may be output. These data should
be ignored by the program reading the touch screen information.
• When more than one point on the panel is turned ON simultaneously, the monitor will not
output appropriate data.

(5) Control from a personal computer
When the following commands are sent to the monitor from a personal computer, the
monitor’s touch panel inputs and outputs can be controlled.
· The monitor’s touch panel automatically enters low power consumption mode approximately
30 seconds after the last contact. The touch panel will automatically recover the next time
the touch panel is touched. However, to operate the touch panel from a personal computer,
you must first confirm that the touch panel is in normal mode by sending a "DI command"
from the computer. ( In the low power consumption mode, the touch panel will not respond
to commands from the computer.)

Notes:
Operation
Reset
Note: If the monitor receives any data while it is sending
data, the data it is sending may be corrupted.
Check the board. When the board is functioning normally, the
monitor will return “Pass □□□□.” (□ means space.)
Stop sending data. However, the monitor can receive commands.
Note: When the monitor is sending sets of data, it will stop
sending at the end of the current data set.
Restart sending data
Set to data creation mode
(Same as the “SM” command.)
Set to the “data creation & break” mode.
Set to the “continuous” mode.
① A CR (0D(H)) must be sent at the end of all commands.
② While the ZM-95T is sending data, it can receive another command from the
computer.
③ Lower and upper case characters can be used for commands.
④ The monitor will execute each command as soon as it has been received.
⑤ When the ZM-95T is in the low power consumption mode, it cannot receive
commands.
⑥ Leave at least 15 ms between characters.

• Each output pulse is 1 set of data.
• The release data will be sent as a single data set when the pen or operator’s finger is lifted
away from the touch panel.

(6) User calibration
The correction used to provide accurate positional information about the location on the touch
panel is referred to as a "user calibration." The "user calibration" is needed to eliminate any
difference between the position being touched and the position displayed on the monitor. This
difference can occur when the touch panel is attached to the display.
Shown below is an example of user calibration.
[ Formula used to calculate the user calibration, based on two points on the touch panel ]
(1024,1024)
Point B •
(0,0)
· Point A data: (XA, YA)
· Point B data: (XB, YB)
Note that XA < XB and XA < YB.
• Point A
· Number of pixels in point A (position on the screen):
(DXA , DYA)
· Number of pixels in point B (position on the screen):
(DXB , DYB)
Note that DXA < DXB, DYA > DYB
The number of pixels (DX1) per data set in the X direction will be,
DX1 = (DXB — DXA) (XB — XA)
The number of pixels (DY1) per data set in the Y direction will be,
DY1 = (DYB — DYA) (XB — XA)
Therefore, the number of pixels (DXD, DYD) at any given position (XD, YD) shall be,
DXD = DXA + DX1 x (XD — XA)
DYD = DYA - DY1 x (YD — YA)
The ZM-95T employs a position detection system that has a very small positional deviation
caused by variation in the resistance level of the touch panel. However, we recommend that
you execute a user calibration for the most accurate results.
