Overview

• Lenses
• Batteries
3.1 Safety warnings
WARNING: Before installing the projector, read first the safety instructions in the safety manual (R5975258)
delivered with the projector.
Insure that the projector is installed in an easy to evacuate room in case of a lamp explosion.
Mercury Vapor Warnings
Keep the following warnings in mind when using the projector. The lamp used in the projector contains mercury. In case of a lamp
rupture, explosion there will be a mercury vapor emission. In order to minimize the potential risk of inhaling mercury vapors:
• Ensure the projector is installed only in ventilated rooms.
• Replace the lamp module before the end of its operational life.
• Promptly ventilate the room after a lamp rupture, explosion has occurred, evacuate the room (particularly in case of a pregnant
woman).
• Seek medical attention if unusual health conditions occur after a lamp rupture, explosion, such as headache, fatigue, shortness
of breath, chest-tightening coughing or nausea.
3.2 Installation guidelines
Ambient temperature check
Careful consideration of things such as image size, ambient light lev
the optimum use of the projection system.
Max. ambient temperature : 40 °C or 104 °F
Min. ambient temperature : 0 °C or 32 °F
The projector will not operate if ambient air temperature falls outside this range (0°C- 40°C or 32°F-104°F).
Environment
Do not install the projection system in a site near heat sources
excessive dust or humidity. Be aware that room heat rises to the ceiling; check that temperature near the installation site is not
excessive
CAUTION: Harmful Environmental Contamination Precaution
Environment condition check
A projector must always be mounted in a manner which ensures the free flow of clean air into the projectors ventilation inlets as well
as free flow at the ventilation outlets. The installati
For installations in environments where the projector is subject to airborne contaminants such as that produced by smoke machines
or similar (these deposit a thin layer of greasy residue upon the projectors internal optics and imaging electronic surfaces, degrading
performance), then it is highly advisable and d
air supply. Devices or structures to extract or shield contaminated air well away from the projector are a prerequisite, if this is not
a feasible solution then measures to relocate the projector to a clean air environment should be considered. Make sure that the
projector never runs with dirty dustfilters
dustfilters on a regular basis and to replace them at any lamp change. Barco reserves itself the right to refuse warranty replacement
of consumables if they have been used in a projector with dirty airfilters. Only use the manufactures recommended cleaning kit which
as this will dramatically reduce the lifetime of the consumables. It is advised to clean the

has been specifically designed for cleaning optical parts, never use industrial strength cleaners on a projectors optics as these will
degrade optical coatings and damage sensitive optoelectronics .
Failure to take suitable precautions to protect the projector from the effects of persistent and prolonged air contaminants will culminate in extensive and irreversible ingrained optical damage. At this stage cleaning of the internal optical units will be non-effective
and impracticable. Damage of this nature is under no circumstances covered under the manufactures warranty and may deem the
warranty null and void. In such a case the client shall be held solely responsible for all costs incurred during any repair. It is the
clients responsibility to ensure at all times that the projector is protected from the harmful effects of hostile airborne particles in the
environment of the projector. The manufacture reserves the right to refuse warranty repair if a projector has been subject to wantful
neglect, abandon or improper use.
What about ambient light ?
The ambient light level of any room is made up of direct or indirect sunlight and the light fixtures in the room. The a
light will determine how bright the image will appear. So, avoid direct light on the screen. Windows that face the screen should be
covered by opaque drapery while the set is being viewed. It is desirable to install the projection system in a room whose walls and
floor are of non-reflecting material. The use of recessed ceiling lights and a method of dimming those ligh
is also important. Too much ambient light will ‘wash out’ of the projected image. This appears as less contrast between the darkest
and lightest parts of the image. With bigger screens, the ‘wash out’ becomes more important. As a general rule, darken the room to
the point where there is just sufficient light to read or write comfortably. Spot li
interference with the screen is minimal.
ghting is desirable for illuminating small areas so that

ts to an acceptable level
Which screen type ?
There are two major categories of screens used for projection equipment. Those used for front projected images and those for rear
projection applications. Screens are rated by how much light they reflect (or transmit in the case of rear projection systems) given a
determined amount of light projected toward them. The ‘GAIN’ of a screen is the term used. Front and rear screens are both rated
in terms of gain. The gain of screens range from a white matte screen with a gain of 1 (x1) to a brushed aluminized screen with a
gain of 10 (x10) or more. The choice between higher and lower gain screens is largely a matter of personal preference and another
consideration called the Viewing angle. In considering the type of screen to choose, determine where the viewers will be located
and go for the highest gain screen possible. A high gain screen will provide a brighter picture but reduce the viewing angle. For
more information about screens, contact your local screen supplier.

Always remove the lens before transporting the projector.
3.4.5 Cleaning the lens
To minimize the possibility of damaging the optical coating or scratching exposed lens surface, we have developed recommendations for cleaning the lens. FIRST, we recommend you try to remove any material from
the lens by blowing it off with clean, dry deionized air. DO NOT use any liquid to clean the lenses.

Proceed as follow :
1. Always wipe lenses with a CLEAN Toraysee
2. Always wipe lenses in a single direction.
Warning: Do not wipe back and forwards across the lens surface as this tends to grind dirt into the coating.
3. Do not leave cleaning cloth in either an open room or lab coat pocket, as doing so can contaminate the cloth.

DVI
Digital Visual Interface is a display interface developed in response to the proliferation of digital flat panel displays.
The digital video connectivity standard that was developed by DDWG (Digital Display Work Group). This connection
standard offers two different connectors: one with 24 pins that handles digital video signals only, and one with 29 pins
that handles both digital and analog video. This standard uses TMDS (Transition Minimized Differential Signal) from
Silicon Image and DDC (Display Data Channel) from VESA (Video Electronics Standards Association).
DVI can be single or dual link.

5.7.1 Address setting
Projector address
Address installed in the projector to be individually controlled.

Default address. Projector will always execute the command coming from a RCU programmed with that common
address.
R5976741 MGP 15 MEDICAL GRADE PROJECTOR 28/04/2004 35
Page 40
5. Getting started
Why a projector address ?
As more than one projector can be installed in a room, the separate projector should be separately addressable with an RCU or
computer. Therefor each projector has its own address.
Set up an individual Projector Address.
The set up of a projector address can be done via the software.
Projector controlling.
Every projector requires an individual address between 0 and 255 which can be set in the Ins tallation menu.
Whentheaddressisset,theprojectorcanbecontrolledby:
• RCU for addresses between 0 and 9.
• computer, e.g. IBM PC (or compatible), Apple MAC, etc. for addresses between 0 and 255.
A projector will respond to a RCU set to the common address ’0’ regardless of what address is set in the projector itself (common
address of projector should also be “0” ).
The RCU is default programmed with address 0 , ’common address’.
If it is necessary to control a specific projector, then enter the projector address into the RCU (only when that
address is between 0 and 9). The projector with the corresponding address will listen to that specific RCU.
Some projectors may operate in domestic environments where other equipments may listen to the common
address “0” , therefore the common address can also be set to “1”.
5.7.2 Displaying and Programming addresses into the RCU
Displaying the Projector Address on the Screen.
1. Press the Address key (recessed key on the RCU) with a pencil.
The projector’s address will be displayed in a ’Text box’
To continue using the RCU with that specific address, it is necessary to enter the same address with the
digit buttons (address between 0 and 9) within 5 seconds after pushing the address key. For example : if the
Address key displays projector address 003, then press "3" digit button on the RCU to set the RCU’s address
to match the projector’s address. Do not press 0–0–3 . This will address the remote control to ’0’ and control
all projectors in the room. If the address is not entered within 5 seconds, the RCU returns to its default address
(zero address) and controls then all projectors in the room.
Address 0 (or 1) should always allow communication with the projector since it is a common address.
Displaying the Projector Address in Standby.
1. Press the Address key (recessed key on the RCU) with a pencil.
All the LED’s on the front of the projector go out.
Then LED1 starts blinking green the number of hundreds. Afte
blinking green the number of units. If this is done, the original status of the leds is restored.
r that LED2 starts blinking the number of tens. Finally LED3 starts
5.8 Digital Zoom
What can be done ?
The Digital Zoom key on the RCU allows to zoom (in or out) one particular part of the image
How to Zoom ?

DICOM
Digital Imaging and Communications in Medicine
It is a standard developed by the American College of Radiology (ACR) and the National Electrical Manufacturers
Association (NEMA). The standard specifies how digital image data can be moved from system to system. In addition, Supplement 28 Part 14 specifies a function that relates pixel values to displayed Luminance levels and is called
Grayscale Display Function Standard.

• Architecture of a typical medical visualization system
• Overview of Barco’s DICOM THEATRE
• Introduction to MGP configuration
6.1 DICOM conformance
®
Need for standardization
A digital signal from an image can be reproduced objectively and accurately. However, the visual interpretation of that signal is
dependent on the characteristics of the systems displaying that image i.e. images produced by the same signal may appear different
depending on the display device. In medical imaging, it is important that there be a visual consistency in how a given image appears,
whether viewed, for example, on the display monitor of a workstation, a projector or as a film on a light-box. In the absence of any
standard which regulates how these images are to be visually presented on any device, a digital image which has good diagnostic
value when viewed on one device could look very different and have greatly reduced diagnostic value when viewed on another
device.
Accordingly, PS 3.14 was developed to provide mapping of digital i
or relationship between digital values and display Luminance produces better visual consistency in how that image appears on
diverse display devices. The relationship that PS 3.14 defines between digital image values and displayed Luminance is based
upon measurements and models of human perception over a wide r
presentation device.
It is also not dependent upon user preferences but uses a DICOM Presentation Lookup Table.
A system is DICOM-compliant when it respects a predefined relationship (PS3.14) between digital input signal
values and display Luminance.

Architecture
A typical example of a medical visualization system is BARCO’s DICOM compliant DICOM THEATRE®.
This system provides consistent images for consulting, reviewing and training applications.
In this system the MGP projector is used as the large screen display device controlled and tuned by the MediCal
software providing optimal image quality and consistency at any time.
Analogy to the typical architecture
• Display function : the function can be chosen to be DICOM, DIN, standard or custom. This is done in the projector.
• Preset: is determined by the user on MediCal
• Control and calibration unit: Role played by MediCal
• Display units: one or more flat panel displays and one or more projectors

• Color temperature, page 67
6 predetermined presets, containing each of them one particular display function and one particular color temperature, are stored
in the projector, they can however be overwritten at any time by MediCal

time of manufacturing. It is advised to re-calibrate these presets to match them to the actual environment.
The factory settings can be restored via the projector’s menu.
Each time a preset is adapted, a calibration has to be done in order to verify conformance and consistency.

Introduction to Autosetup
Autosetup creates the best suited image file for the connected source.
Therefore Autosetup calculates/measures several parameters of the sources:
• Total pixels per line
• Start pixel
• Phase
• Contrast/Brightness levels
The measure of the total number of pixels per line can be done through 2 methods
• Limited scan: a windowing is used to allow fast tracking, takes about ...
• Full scan: tracking is done over the full range, takes about ...
How to setup the scan method ?

8.6 Scaling
What are the different scaling methods ?
• Best Fit : forces to use the maximum resolution of the LCD panels by preserving the selected aspect ratio, "Aspect ratio", page
51
• None : uses the native resolution of the source, the aim being here to always show the resolution of the source, independently
of the resolution of the LCD panels.
The “show native resolution” function will handle the sources as shown in the table.
• Full screen:TheFull screen method forces to use the complete native resolution of the LCD panels independently of the native
resolution of the source.

The MGP10 offers a user-friendly way to select the desired input to be projected. 5 different selectable inputs are available in the
input selection menu, each of them is indicated with 2 icon :
• a slot number icon : icon representing the shortcut numeric key to be entered on the RCU to select the same input
• a Barco icon : indicates the presence of that particular source.
Another way of selecting an input is via the RCU using the numeric keys or via the local keypad.
BNC configuration
The advanced part of the source selection menu allows to configure the 5 BNC’s. In other words, one must specify which signal is
present on the 5 BNC’s in order to allow the appropriate processing.
• Data on BNC’s : must be selected when a data signal is present on the BNC’s.
An example is a RGBHV signal coming from a computer.
• Component video : must be selected when a signal of the type PR/Y/PB is connected to the BNC’s.
An example is a component signal coming from a professional DVD player
•RG
B Video : must be selected when an RGB video signal with Sync on Green or sync on H is presented on the BNC’s.

CIE graph coordinates: x = 0.28 ; y = 0.304
• Bluebase
CIE graph coordinates: x = 0.25 ; y = 0.305
Since the projector is operating most of the time in greyscale mode meaning a B/W signal is to be reproduced, the color temperature
setting can be seen as an adjustment of the neutral greyscale color temperature.
These 2 predefined color temperatures (as well as Full White ) are used to form, in combination with a display function, a preset for
greyscale reproduction.

What are the different lamp modes ?
Single mode
The projector will always switch to the lamp with the shortest runtime when the difference between the runtimes of lamp1 and lamp
2 reaches 100 hours, switching from one lamp to another happens only at switching on of the projector and not during operation.
When the lamp fails or reaches its maximum runtime the projector switches automatically to the other lamp without interrupting the
projection.The failure is logged and the lamp will never be initialized in the future.

Single mode operation: switching principle
Dual mode
Both lamps are working.
When one lamp fails, the projector continues the projection using the remaining lamp.

10.8 Input Balance
CAUTION: The input balance adjustmentis only for Barco authorized technicians !
Introduction: Unbalanc
When transporting signals, there is always a risk of deterioration of the information contained in the signals.
In case of information contained in the amplitude of the signals which is the case of data color signals (R, G, B),image 10-20 ,we
are quite sure that the amplitude of these color signals is subject to alterations.
An example of alteration may be a DC component added to the signal, in the form of a DC offset repositioning the black level, since
this black level (“brightness”) will become crucial later on ( clamping circuit) it will result in “black not being black”.
Another value that is subject to alteration is the amplitude of the signal, resulting in an altered “Gain” of the signal (“white level” or
contrast ).
The alterations of the three color signals will happen independently i.e. the colors will end to be unbalanced, image 10-21

Analog Digital Conversion
The analog color signals must pass through an Analog/Digital conversion circuit prior to any digital processing in the PMP.
A typical ADC transforms the analog value into an 8 bit coded digital signal.
The graphic shows that when converting a signal containing a DC offset component the range of the converter is not optimally used.

The objective of input balancing
The objective in input balancing is to “set” the same black level and the same white level for the three colors of a particular input
source.

The logo display is only possible in the full screen mode, a logo can thus not be displayed (rescaled) in a
window in the PiP mode.
When there is no signal connected, the projector will also start its standby timer countdown (if enabled) and
shuts down after the predetermined time.
