1. Overview
The LCD monitor SCD 1597-R/RT/R8S has been developed and constructed especially for
industrial applications. This monitor can be used in applications where a standard CRT-
device would be unsuitable, due to space or environmental restrictions.
Its compact enclosure opens up a wide spectrum of possible application areas for the SCD
1597-R/RT/R8S, ranging from air-conditioned computer rooms in a 19" rack, to the
immediate vicinity of machinery in a special protective enclosure. As is the case for all
industrial systems, the monitor has been designed to withstand the particular demands
placed upon such equipment, e.g., it is immune to electromagnetic radiation and can
withstand a large temperature range.
The trend-setting LCD technology in this monitor has relegated picture geometry distortion
and colour patches to the past. Even at the low refresh rate of 50 Hz. the screen remains
flicker-free. The SCD 1597-R/RT/R8S thus fulfils even the strictest ergonomic requirements.
Pictures of lesser resolution are expanded to fill the screen.
The SCD 1597-R/RT/R8S can simultaneously display up to 262,144 colours enabling realistic
colour images and videos to be displayed. The LCD-monitor contains special hardware to
convert a standard analogue VGA video signal for the display controller. Compatibility with
conventional CRT monitors is, thus, guaranteed.
It is very easy to adjust the monitor settings using the clearly designed OSD (On Screen
Display). The “Automatic Alignment” function does away with the need to carry out tedious
adjustments such as picture position and phase. At the press of a button, the monitor
performs these alignments automatically.
The SCD 1597-R/RT/R8S is equipped with an active 15.0” TFT display module with a
maximum resolution of 1024x768 pixels. The integrated power management system VESA
DPMS, allows a significant reduction in power consumption when the synchronisation signal
from the computer has been switched off, compared with that under “normal” operation.

1.2.1. Instructions for Handling Assemblies Susceptible to
Electrostatic Shock
Most of the assemblies within the SCD 1597-R/RT/R8S LCD-monitor contain components
which can be destroyed by electrostatic voltages. It is also possible for the assemblies to be
damaged in such a way that total failure does not occur.
If you (as an authorised service technician) are handling such assemblies then the following
precautions should be observed:
• When such assemblies are being handled, a means of electrostatic discharge must be
available. This can be, for example, an earthed object, which can be touched to discharge
electrostatic voltages.
• This applies to all tools used (insulated). They must also be discharged at an earthed
object.
• When assemblies are removed or added to the system, the unit must always be switched
off and the power supply cable unplugged.
• Vulnerable assemblies should always be held by their edge. Avoid touching tracks and
contact pins.

2.4. Electrical Installation
Before connecting the SCD 1597-R/RT/R8S to the power supply, a check should be carried
out as to whether the VGA connector is plugged in properly and that the screws tightened.
The monitor can be connected directly to the power supply (note the polarity of the supply). If
a video signal is connected, the image will appear immediately on the screen.
There are many possible reasons why an image might fail to appear on the display after it
has been switched on:
– no video signal connected
– no synchronisation signal connected
– horizontal and vertical synchronisation signals are connected the wrong way round

3.2.1. Brightness / Contrast
The picture brightness (not backlight) and the contrast are adjusted here.
3.2.2. Colour Temperature
Four different colour temperature values are available here (9500K, 8500K, 6500K, 5000K).
The desired temperature is selected by pressing the SUB menu key. Pressing the “UP” key
calls up a sub menu where the selected colour temperature value can be adjusted. There are
three adjustment elements for the three colours, allowing the desired colour temperature or
colour tone, to be set.
3.2.3. Frequency / Phase
The frequency setting allows the pixel clock frequency to be adjusted. This will only have to
be adjusted if the automatic alignment was unable to determine the correct pixel clock
frequency.
The phase setting allows slight picture disturbances to be eliminated.
3.2.4. Status
This displays the current display resolution and the horizontal and vertical frequencies.
3.2.5. Position
This menu point allows the picture to be shifted in the horizontal and vertical directions.
3.2.6. Scaling
This contains four sub menu points which influence the manner in which images of greater or
lesser resolution than that of the display are represented.

Operating Instructions
LCD-Monitor SCD 1597-R/RT/R8S Page 17 / 22
DOC-Nr.: B3 0038 D4.DOC
3.2.7. Horizontal / Vertical Pan
This setting enables the screen contents to be shifted horizontally and vertically when
pictures with a greater resolution than the display are shown. This requires “Normal Scaling
Modes” to be set to “One to One”. If, e.g., a 1280x1024 picture is to be shown on a display of
1024x768 pixels then, with the “One to One” setting, only a part of the entire picture will be
visible. Here, the desired part of the entire image can be displayed.
Normal Scaling Modes
There are three possible values for this menu point, with the following functions:
One to One
This setting causes the picture to be displayed without expanding or
contracting it. If the picture has a lower resolution than the display
then a black frame will appear. If the picture has a greater resolution
than the display then only the top left-
hand corner of the picture will
appear.
Fill Screen This setting causes the picture to fill the entire display.
Fill to Aspect Ratio
This setting expands the picture as much as possible while
maintaining the height to width ratio of the picture.
Non Linear Scaling Parameters
In this sub menu point the are three possible settings each for the horizontal and vertical
sizes allowing the picture height and width to be adjusted independently.
Horiz Clipping Horizontal expansion of the picture
Horiz Offset
Horizontal shifting only if the picture width, set by the horizontal
clipping, is larger than the displayable picture width.
Horiz Stretch This is a horizontal linearity setting for the picture width, i.e., if the
value is negative, the picture is compressed more at the horizontal
edges and stretched more in the middle.
A positive value has the opposite effect.
Vert Clipping Vertical expansion of the picture.
Vert Offset Vertical shifting only if the picture he
ight, set by the vertical clipping, is
larger than the displayable picture height.
Vert Stretch
This is a vertical linearity setting for the picture height, i.e., if the value
is negative, the picture is compressed more at the vertical edges and
stretched more in the middle.
A positive value has the opposite effect.

DOC-Nr.: B3 0038 D4.DOC
3.2.8. Sharpness
Five levels of sharpness are available. The sharpness can only be adjusted if the picture has
a higher or lower resolution than the display. Assigning a relative unsharpness can, to an
extent, reduce interpolation artefacts which occur during picture expansion. This means that
the user finds characters more easily readable. A value of 1 gives minimum non-sharpness
and 5 give maximum non-sharpness.
3.2.9. Zooming
This function enables information in the middle of the display to be enlarged as if viewed
through a magnifying glass. The selected zoom factor remains active after the OSD-menu
has been exited.
3.2.10. Language
The language of the OSD is selected here.
3.2.11. Utilities
Various settings are available here to control the behaviour and testing of the monitor.
User Settings
Six possibilities are available in this sub menu, as follows:
OSD Horz Position Horizontal position of the OSD on the display
OSD Vert Position Vertical position of the OSD on the display
OSD Backround Adjust the OSD background.
Translucent = transparent
Opaque = not transparent
User Timeout
This allows the time which elapses between the last key press and
the disappearance of the OSD to be set. Settings between 5 and 50
seconds in steps of 5 seconds are allowed.
DPMS
Activates/deactivates the power management. If the DPMS is active
then the monitor switches off automatically when there is no sync.
signal, i.e., the screen goes dark. Before it switches off, a “NO signal”
message appears on the screen.
If the DPMS is not active then the “NO signal” message stays on the
screen until a valid video signal is applied to the monitor.
Auto Source Select This has no function.

DOC-Nr.: B3 0038 D4.DOC
Gamma Adjust
This function allows the “gamma curve” to be adjusted in 32 steps, i.e., the incoming colour
values are modified by a particular factor and passed on to the display. One of the 32 points
can be selected from an index. The output values for red, green and blue can then be set for
the selected point. A linear interpolation occurs between the 32 points.
This adjustment should only be carried out by qualified personnel.
Test Pattern
This causes a staircase in red, green, blue and grey to be displayed on the screen for test
purposes.
Reset to factory defaults
This function causes all settings to return to the factory default values.
3.3.12. Automatic Alignment
Automatic alignment of the monitor is automatically activated if a picture is displayed which
has never been displayed before. This function can also be activated manually by pressing
the “+” key while the OSD menu is not currently being displayed. A window appears which
contains information on the video signal source. Pressing the “-“ key then causes the
automatic alignment procedure to start. The message “Auto in Progress” appears on the
screen during the alignment. After the procedure has finished the previous picture is restored
to the screen. The brightness, contrast, frequency, phase and picture position are all
automatically adjusted.
If, due to insufficient picture information, the automatic alignment does not work correctly, the
parameters can all be adjusted manually as described above.
