1 Overview
The LCD monitor SCD 1297 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 1297, ranging from air-conditioned computer
rooms behind a switching cabinet door, 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
1297 thus fulfils even the strictest ergonomic requirements. Pictures of lower resolution are expanded
to fill the screen.
The SCD 1297 can simultaneously display up to 262144 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 1297 is equipped with an active 12.1” TFT display module with a maximum resolution of
800x600 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.
Three versions of the monitor are available:
stand-alone chassis SCD1297-C(CT with Touch)
mountable with front plate SCD1297-E (ET with Touch)
19“ rack 6 HE SCD1297-R(RT with Touch)

1.2.1Instructions for Handling Assemblies Susceptible to
Electrostatic Shock
Most of the assemblies within the SCD 1297 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 disconnected.
Vulnerable assemblies should always be held by their edge. Avoid touching tracks and contact pins.
2 General Installation
Preparation for installing the LCD-monitor include the following points:
Removal of all packaging
Checking of components for damage
Comparison of components received with those on the delivery note
Connection to the computer system and power supply
Building into your system, bearing in mind technical and ergonomic aspects
2.1 Removing the Packaging and Checking Individual Parts
After unpacking all the delivered components, they should be checked for completeness and for
possible transport damage (visual inspection). If any deficiencies are found then please contact the
service department given on the delivery note. Have the delivery note number, serial number and a
description of the deficiency to hand.
The original packaging should be kept for future transportation.

Thermal Problems
In order that the LCD-monitor maintains an optimum operating temperature while in use, air must be
allowed to circulate freely around the SCD 1297 enclosure. It is particularly important that the rear of
the system is kept free.
Please bear in mind that increased temperatures can lead to defects and to a significant reduction in
the lifetime of the monitor.
EMC Problems
This LCD-monitor is a piece of equipment designed for building into an industrial system. The
operator of the entire plant is responsible for maintaining electromagnetic compatibility according to
EMC laws.
Safety Problems
All voltage and signal connections must adhere to appropriate legal requirements.
Ergonomics
The screen should be easily viewable from all sides and without reflections.
2.2.1Installation of the AC/DC-power supply unit or 24V-DC/DC-
Converter
Either an AC/DC power supply unit or a DC/DC converter can be used to supply the control panel with
24DC. If an AC/DC power supply unit is used, it is attached to the enclosure using the bracket
indicated in Fig. 1 on page 10.
If the DC/DC converter, which is delivered with the unit, is to be used then it should be inserted below
the AC/DC power supply unit shown in Fig. 1, so that the 24V connector is accessible. The DC/DC
converter should then be screwed to the enclosure using to the two holes provided for the bracket.
2.3 Cable Connections and Pin Assignments
The LCD-monitor has been tested and set-up in the factory. Before use, the power supply and the
VGA signals should be connected to the sockets provided. Connections to the monitor should adhere
to EMC regulations.

Power Supply
Power is supplied to the SCD 1297 via a standard power connector on the rear of the unit.
Pin Name Description
O GND Power supply ground GND
+12V Power supply +12VDC
2.4 Electrical Installation
Before connecting the SCD 1297 to the power supply, a check should be carried out as to whether
the VGA connector is plugged in properly and that the screws are tightened. There is a compartment
on the rear of the unit to hold the standard power supply unit delivered with the display.
The monitor can, however, also be powered by a 12 V supply (observe polarity of the power supply
connections).
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 VGA signal connected
- no synchronisation signal connected
- horizontal and vertical synchronisation signals are connected the wrong way round
-
