VistaGRAPHX 5000 is a professional-quality DMDprojector that uses Digital
Light Processing(DLP) technology from Texas Instruments to achieve high-
brightness multimedia and video projection. It is ideal for use in large audience
venues in which there may be high levels of ambient light, such as in
auditoriums and lecture halls. The VistaGRAPHX 5000 is compatible with
standard international video formats and can interface with IBM-compatible
PCs, Macintoshcomputers, and workstations. Features include:
◊ 1024 X 768 pixels resolution
◊ over 4500 ANSI lumens, contrast ratio of 250:1 ANSI, 400:1 full field
◊ interchangeable lenses for diagonal screen sizes up to 40 feet
◊ NTSC, PAL and SECAM compatible (requires optional decoder)
◊ displays input from PCs, VCRs, laser-disc players, video cameras, etc.
◊ intuitive on-screen menus
for setup and control
◊ built-in and infrared (IR)
remote keypads
◊ controller and switcher
compatibility
◊ keypad selectable input
switching
◊ RS-232 input with loop-
through for networking
multiple projectors
◊ RS-422 input for long distance control
◊ 5-language capability
◊ modular design for ease of servicing
VistaGRAPHX 5000 accepts data/graphics and video input signals for projection
onto flat or curved front or rear projection screens. High brightness light is
generated by an internal 1000 watt CERMAXXenon lamp. This light is
modulated by three DMD (digital micromirror device) panels which each
provide digitized red, green, or blue color information. Light from the "ON"
pixels of each panel is reflected, converged and then projected to the screen
through a single front lens, where the pixels are all superimposed to create a
sharp full-color image.
The projector body is comprised of aluminum panels with an ABS front bezel.
Covers can be removed as necessary for quick replacement of the lamp or filter.

Screen type is important when designing a projection system. Inexperienced
users or installers should always consult their dealer when deciding on screen
type. The following guidelines explain the differences between screen types.

There are two basic screen types: flat and curved. The choice between a flat
screen or a curved screen is dependent on audience viewing angle and screen
gain. There is always a trade-off between viewing angle and gain. Viewing
angles for both screen types are illustrated in Figure 2-1 and Figure 2-2 (plan
views).
Flat screens offer a gain of about 1 with a viewing angle just less than 180°.
Incident light reflects equally in all directions so the audience can see the display
from various angles. Because of the lower gain, flat screens are more effective
when ambient lighting is reduced.

)LJXUH 5051 $XGLHQFH &RYHUDJH ZLWK &XUYHG 6FUHHQ
Curved screens have gains larger than 1 (due in part to the screen material) and
viewing angles much less than 180°. Most curved screens have different
horizontal and vertical viewing angles. Incident light does not reflect equally in
all directions. The reflected light concentrates in a conical volume or "viewing
cone". Audiences within the viewing cone see a brighter image than that from an
equal area on a flat screen. Audiences outside the viewing cone see a dimmer
image.
NOTE: VistaGRAPHX 5000 lenses are designed primarily for use with flat
screens. However, its depth-of-field range allows the lens to be focused on
curved screens as well. Focus remains sharp in the corners, however there may
be significant pincushion distortion, primarily at the top of the screen.

5HDU 6FUHHQ ,QVWDOODWLRQV
There are two basic types of rear screens: diffused and optical. A diffused screen
has a surface which spreads the light striking it. Purely diffused screens have a
gain of less than 1. The main advantage of the diffused screen is its wide viewing
angle, similar to that of a flat screen for front screen projection. Optical screens
take light from the projector and redirect it to increase the light intensity at the
front of the screen. This reduces it in other areas. A viewing cone, similar to that
of a curved front screen installation, is created.
To summarize, optical screens are better suited for brightly lit rooms where the
audience is situated within the viewing cone. Diffused screens are best suited
when a wide viewing angle is required but there is low ambient room lighting.
Screen size may be from 5 to 40 feet diagonal, depending on the lens you are
using. For instance, a 1:1 lens produces a 6-30 foot image size, whereas a 4-7:1
zoom lens produces a 10-40 foot image size. Choose a screen size which is
appropriate for your lens and application. Keep in mind that if the projector will
be used to display text information, the image size must allow the audience to
recognize all text clearly. The eye usually sees a letter clearly if eye-to-text
distance is less than 150 times the height of the letter. Small text located too far
from the eye may be illegible at a distance despite the image being projected
sharply and clearly on the screen.
To fill a screen with an image, the aspect ratio of the screen should be equal to
the aspect ratio of the image. The aspect ratio of an image is expressed as the
ratio of its width to its height. Standard video from a VCR has a 4:3 or 1.33:1
aspect ratio. For example, to display a VCR output with a 4:3 aspect ratio onto a
10 foot (3m) high screen, the width of the screen must be at least 13.3 feet (4m).
Note: Screen size is often specified as diagonal size. Screens specified by
diagonal size have aspect ratios of 4:3. Screens with other aspect ratios are not
typically specified by diagonal size.
The high brightness output of VistaGRAPHX 5000 is well suited for locations
where ambient lighting is less than optimum for projection; however, it is
desirable that the projector be operated in an ideal projection room environment.
For temporary installations where the room may not be designed for projection,
there are many simple things which can be done to avoid problems caused by
unwanted light.
Visiting a movie theater can give you an idea of what makes a good projection
environment. Walls, floors and furnishings are dark and matte finished. A
projection room should not have white reflective ceilings or non-directional
lighting such as fluorescent lights. The white ceiling spreads light, making the
room appear brighter. Keep lighting and reflections to a minimum.
If it is not possible to eliminate fluorescent lights, consider using parabolic
reflectors ("egg crates") to direct light down to the floor. Incandescent spot
lighting is a better way to obtain illumination. Light dimmers or rheostats allow
you to further control the lighting.

Outside windows are undesirable in any projection room. A small crack between
curtains on a sunny day can wash out a projected image. If you do have
windows, make sure that window coverings are opaque and overlapping — some
window coverings are designed to provide up to 100 percent blockage of outside
light. Ideally, the material should have a matte finish.
To minimize the effects caused by unwanted light from door and aisle ways,
carefully choose the position of your projector and screen. Figure 2-3 shows an
installation where poor screen placement allows too much unwanted light to
enter the screen. In Figure 2-4, the screen and the projector are positioned so that
unwanted light is minimized.

)LJXUH 5071 %HWWHU 6FUHHQ 3ODFHPHQW
Even with all lighting removed it is still possible that room reflections within the
room can degrade the image. Light from the projection screen should be
absorbed by the ceilings, walls and floors so that it will not be reflected back to
the screen. Again, reflective surfaces should be kept to a minimum.
Here are some other considerations and tips which can help you improve your
installation:
• Ventilation is an important factor when preparing a projection room. The
ambient temperature should be kept constant and below 35°C (95°F). Keep

the projector away from heating and/or air conditioning vents. Changes in
temperature can cause drifts in the projector circuitry which may affect
performance.
• Keep the projector away from devices which radiate electromagnetic energy
such as motors and transformers. Common sources of these are slide
projectors, speakers, power amplifiers, elevators, etc.
• For rear screen applications, less space is required if a mirror is used to fold
the optical path.
• Choose the right screen size for the application:
◊ As screen size increases, magnification increases which reduces
brightness. Select a screen size which is appropriate for the venue,
but not larger than that required.
◊ Installing a large screen in a small room is similar to watching
television close up; too large a screen can overpower a room. A good
rule of thumb is to be no closer than 1.5 times the width of the
screen.
◊ Larger screens require greater attention to lighting conditions.
• When laying out the projection room, consider positioning the projector and
screen in a manner which will achieve maximum audience coverage and
space efficiency. For example, placing the screen along the larger wall in a
rectangular room will reduce audience coverage. Figure 2-5 shows two
examples of how audience coverage is maximized.

Installation type, screen type, and lighting all affect where the projector is
positioned. In addition, both throw distance (the distance between the projector
and screen) and vertical position (the height of the projector in relation to the
screen) must be determined for every new installation. Both depend on the
screen size and projector lens type you are using. Make sure that the room can
accommodate the required position of the projector for the chosen screen size.
Throw distance is the distance between the projector's front feet and the screen.
It is measured perpendicular to the lens surface and screen surface. As you move
the projector farther from the screen, the image becomes larger.

Throw distance is roughly equal to the horizontal width of the screen multiplied
by the type of lens you are using (for example, if using a 3.9:1 lens, throw
distance should be approximately 3.9 [the screen width). Once you know your
screen size, you can closely estimate how far away the projector should be, as
shown in Table 2-1. Always refer to Appendix E for permanent installations.

NOTES: 1) While throw distance is measured perpendicular to the screen and
projector, this measurement is not necessarily parallel to the floor—both
projector and screen may be inclined together. 2) It is good practice to simulate
the setup with the projector fully warmed-up to determine the actual throw
distance required. 3) Always refer to Appendix E for permanent installations.
The vertical position of the projector in relation to the screen also depends on the
size of the screen and the lens type. Correct vertical position helps ensure that
the image will be rectangular in shape rather than keystoned (having non-parallel
sides) and that image quality remains at its best.
Vertical position can be manually offset—that is, the image can be moved up—
using the vertical adjustment knob on the front of the projector. The range of
adjustment depends on the lens type you are using (Table 2-2). In addition, refer
to Figure 2-6 to see more clearly how the pixel offset ranges affect the placement
of your image in relation to the vertical location of the projector.

NOTES: 1) If you cannot move the image enough for your installation, or if the image
becomes keystoned or exhibits uneven brightness, the projector is probably too high or
low in relation to the screen. 2) Recommended offset ranges can be exceeded, however
this may affect image focus and/or brightness.

For typical front or rear floor mounts, mount the projector
on a secure table or cart. Take care with a mobile cart—
avoid sudden stops, excessive force and uneven surfaces that
maycause the projector and cart combination to overturn.
The table or cart should be reasonably level. Fine adjustments to the projector
level can be made by adjusting the height of the projector legs; refer to 2.7,
Leveling for details.

Note that VistaGRAPHX 5000 can be rotated and mounted at any vertical angle-
i.e., you can tilt the projector forwards or backwards as much as desired for your
application. The side-to-side tilt, however must not exceed 45° (see Figure 2-7).
This limit ensures that the arc lamp in the projector operates properly and safely.

If the projector is to be inverted, a ceiling mount fixture is required. Electrohome
provides a ceiling mount kit for assembly and installation by a dealer/installer.
For more information, contact your dealer or Electrohome.
In rear screen applications where space behind
the projector is limited, a mirror may be used
to fold the optical path. See Figure 2-8. The
position of the projector and mirror must be
accurately set. If considering this type of
installation, call your dealer for assistance.
The rear panel of the projector has two standard input panels to which you may
connect a variety of sources. The upper right panel (INPUT 1) accepts an RGB
input from an external RGB source with audio follow-through. The lower left
panel (if video decoder module is installed) accepts composite video (INPUT 3)
or S-video (INPUT 4) and audio from devices such as video tape or disk players.
There are also several optional interfaces available for connecting other sources
(INPUT 2). Such an option installs in the upper left panel. See Figure 2-9.

The RGB input (INPUT 1) includes BNC type connectors for connection to a
variety of RGB sources. Such sources include VGA, SVGA, XGA, Mac,
PowerMac, DEC, Sun, SGI and others. VistaGRAPHX 5000 supports multiple
sync types: sync-on-green for data, composite, and separate H & V.
NOTE: Depending on the source, you may need a custom adapter cable that has
BNC connectors at the projector end and different type of connector at the other
(such as a 15-pin "D" connector for computer sources). Contact your dealer or
Electrohome.
Connect the sync BNC input(s) first. Then connect the red, green and blue
source outputs to the RED, GREEN, and BLUE inputs on the panel. If the source
uses sync-on-green, only the red, green, and blue connections are required. If the
source provides a composite sync output, connect it to the H/C SYNC input. If
the source provides separate horizontal and vertical sync outputs, connect
horizontal sync to the H/C SYNC input and connect vertical sync to the V SYNC
input. See Figure 2-10.
Connect YUV (component) video as follows:
Yto "Green"
U(also called B-minus-Y) to "Blue"
V(also called R-minus-Y) to "Red"
NOTE: VistaGRAPHX 5000 does not automatically recognize a YUV signal.
When using YUV video, you must specify this signal type within the Image
Settings menu so that the projector can distinguish between this signal and other
RGB sources. See 3.6, Adjusting the Image.

To control audio levels in an audio/visual system, connect pre-amplified (line
level) audio inputs to the left and right channel audio inputs on the INPUT 1
panel. Then connect the audio outputs to external audio amplification equipment
for sound output. All audio connection cables require standard RCA type phono
plugs.
The Composite/S-Video input provides simultaneous connection of both a
composite video source (INPUT 3) and an S-Video source (INPUT 4).
If connecting a S-Video source, use either the 4-pin mini DIN connector or the Y
and C BNC connectors (luminance and chrominance) — do not use both as
input. If connecting a composite video source, use the Composite BNC
connector or the RCA phono jack — do not use both as input. See Figure 2-11.
NOTE: If using the loop-through feature for composite or S-Video input, see
"Video Termination" in 3.7, Adjusting and Checking System Parameters.

If you want to use an extra video source in addition to the video source(s)
connected at Input 3 and/or Input 4, connect either a Composite or S-Video
source to Input 1 as shown in Figure 2-12.

Optional interface modules allow you to increase the total number of inputs and
to accommodate other signal types. These modules may be installed in the upper
left section of the control panel on the rear of the VistaGRAPHX 5000 (Input 2).
They are:
• RGB Input Module
• RGB Loop Thru Module
• Composite/S-Video Module
• HDTV Input Module
• PC Analog Input Module
NOTES: 1) Installation of optional interfaces must be done by qualified service
personnel only — contact your dealer or Electrohome. 2) See Appendix F,
Optional Input Modules for a brief description of each interface.
Plug the special notched AC line cord (power cord) into the line input socket
located at the left rear of the projector (Figure 2-13). Plug the three-prong end of
the line cord in a grounded AC outlet. Input voltage to the projector must be
between 180 and 264 VAC, 50 or 60 Hz. The power source must be capable of
supplying 1500 watts of power to the projector.

Caution: Once the projector is turned off, the lamp cooling fans will continue to
run for approximately five minutes to ensure that the projector and lamp have
sufficiently cooled, at which point the fans will automatically shut off. To avoid
damaging the projector, never unplug the line cord while the lamp cooling fans
are running. Do not unplug the projector in order to power down.
VistaGRAPHX 5000 is set up at the factory for use in a front screen, floor mount
orientation. If the installation is ceiling mount or rear screen, you may notice that
displayed images are upside down and/or reversed. To correct, you must change
the image orientation from within the Preferences menu (you may prefer to do
this before physically
installing the projector). See
Section 3, Operation for
further information.
In the Preferences menu,
highlight and select the
"Image Orientation" pull-
down list. From a front
screen floor mount
installation, select from Rear,
Inverted Rear, Front or
Inverted Front according to
your intended installation:
For most installations, the lens surface
of the VistaGRAPHX 5000 projector
must be parallel to the screen to
prevent keystoning. To make small
corrections to the projector's level,
rotate each leg as necessary to raise or
lower.

Once the VistaGRAPHX 5000 is properly set up and projecting an image on
screen, you are ready to make quick manual display adjustments.
If you are using a zoom lens, turn the outer shell of the lens barrel to decrease or
increase the size of the image at the current throw distance. Note: Do not touch
the lens surface as it can be easily damaged.
Turn the Focus adjustment knob (next to lens barrel) until you obtain the best
overall image clarity.
VistaGRAPHX 5000 includes a Vertical Offset adjustment knob to provide
vertical image shifting (raising and lowering) without causing keystone
distortion. Proper adjustment can also maximize display brightness. Turn the
knob until you achieve the best overall brightness without causing a distortion in
picture geometry.
For further display adjustments through keypad commands and on-screen menus,
refer to Section 3, Operation.
Use serial communication ports when controlling VistaGRAPHX 5000 with a
personal computer having a serial interface or when using the projector with a
Marquee switcher. VistaGRAPHX 5000 serial ports are located on the lower
right portion of the projector's rear control panel as shown in Figure 2-14.

NOTES: 1) All VistaGRAPHX 5000 serial connections require a 9-pin D
connector. Refer to Appendix D for complete cable wiring requirements. 2) The
"NETWORK OUT" port is provided for networking applications only — see "If
using multiple projectors", below.

You may wish to use a computer rather than a keypad for controlling the
projector and for performing other special functions. From most computers,
connect an RS-232 serial communication cable between the computer and the
projector serial port labeled "NETWORK IN" (Figure 2-15). Then set the
projector baud rate to match that of the computer. Changing the baud rate is
described in 3.7, Adjusting and Checking System Parameters.
NOTE: In rare instances, some computers can provide RS-422 serial
communications (generally through a plug-in adapter or external converter). See
The RS-422 Port, below.

In rare instances, some computers can provide RS-422 serial communications
(generally through a plug-in adapter or external converter) rather than the typical
RS-232 found on most computers. RS-422 communications occur at a higher
voltage level than RS-232 and are especially useful for distances greater than
600 feet. The projector’s RS-422 port is permanently set at 9600 baud.
If you wish to control the projector with a computer having RS-422 capability,
connect the computer to the projector’s RS-422 port instead of the port labeled
“NETWORK IN”. Again, use RS-422 only if you are certain that your computer
has RS-422 capability (consult your documentation). See Figure 2-16.
