VistaPro 2000 is a professional-quality DMDprojector that uses Digital Light
Processing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
VistaPro 2000 is compatible with standard international video formats and can
interface with IBM-compatible PCs, Macintoshand computer workstations.
Features include:
◊ 848 x 600 pixels resolution
◊ 2000 ANSI lumens
◊ interchangeable lenses
◊ diagonal screen size up to 30 feet
◊ NTSC, PAL and SECAM compatible (export model requires optional decoder)
◊ displays input from PCs, VCRs, laser-disc players, video cameras, etc.
◊ intuitive on-screen menus

◊ RS-232 input with loop-
through for networking
multiple projectors
◊ 5-language capability
◊ modular design for ease of servicing
VistaPro 2000 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 1 kilowatt 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 powder-coated aluminum and an ABS front
bezel. Covers can be removed as necessary for quick replacement of the lamp or
filter. The projector's modular internal design provides for ease-of-service and
minimal down-time.

This section explains how to install and set up the projector. If you are familiar with the projector and want to
quickly set it up for temporary use, follow the Quick Setup instructions. For a complete setup, follow the
instructions and guides covered in the remaining subsections.
NOTES: 1) The lens for the projector is not mounted when shipped from the factory. For instructions on how to
install or replace a lens, refer to 4.5, Replacing the Lens. 2) This manual assumes the video decoder is installed.
Follow these 6 steps for quick setup of the VistaPro 2000.
Position the Projector
Set the projector at the proper throw distance (projector-to-screen distance) and
vertical position. See 2.3, Projector Position and Mounting. Make sure that the
projector is level from side-to-side (see 2.7, Leveling).
Connect a Source
Locate the input panels at the rear of the projector. The upper right panel accepts
an RGB input (via BNC connectors). The lower left panel accepts a composite
video and S-video input. Connect a source to the appropriate panel.
Connect the Line Cord
Plug the special notched AC line cord (power cord) into the AC power socket at
the left rear of the projector. This cord is rated at 15 amps rather than the 8-10
amps in other typical cords. Input power required is 100 VAC to 240 VAC, 50 to
60 Hz @ 11 amps.
WARNING:
Use only the special notched AC line cord. Do not
attempt operation if the AC supply is not within the
specified voltage and power range.
Turn the Projector ON
Using either the built-in or IR remote keypad, press and hold for a second
to turn the projector on. The VistaPro logo will be displayed after a brief delay.
Let the projector warm up for five minutes.
Select a Source
Using either the built-in or IR remote keypad, press , , or to
select and display the image for the source you have connected in Step 2.

Make Necessary Display Adjustments
With the input image displayed, rotate the lens barrel to increase or decrease
image size (applies to zoom lenses only). Then rotate the nearby Vertical Offset
knob to achieve the best overall image position and brightness without a
distortion in picture geometry. Next, rotate the focus adjustment knob (next to
the lens barrel) to achieve best focus. Press to refine other display
adjustments, press if you want to select a different source. See 3.5, Using
Sources.
Although VistaPro 2000 delivers a high brightness quality output, the final
display quality could be compromised if the projector is not properly installed.
This subsection discusses issues you should consider before proceeding with a
final installation. Even if you do not intend to use VistaPro 2000 in a fixed and
permanent installation, this subsection will help you to better understand what
may be done to enhance display performance.
Choose the installation type which suits your needs: front or rear screen, floor
mount or inverted mount.

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.

VistaPro 2000 User's Manual

Front Screen Installations
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 Figures 2.1 and 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.
Figure 2.1. Audience Coverage with Flat Screen
Figure 2.2. Audience Coverage with Curved Screen
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: VistaPro 2000 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.

INSTALLATION & SETUP
VistaPro 2000 User's Manual
2-4
Rear Screen Installations
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 8 to 30 feet diagonal (2.4 to 9.1 meters) for projector
models with 5:1, 1.5:1 - 3:1 (zoom), and 3:1 - 7:1 (Zoom) lenses. If the projector
has a 1.2:1 lens, screen size can range from 5 to 25 feet diagonal (1.5 to 7.6
meters). Choose a screen size which is appropriate for your lens and application.
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 must 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 VistaPro 2000 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.
Figure 2.3. Poor Screen Placement
Figure 2.4. Better Screen Placement
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
Other Considerations

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.
Figure 2.5. Screen Locations for Maximum Audience Coverage
As mentioned, 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 must be determined for every new
installation. Both are calculated based on screen size and projector lens type.
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
(measured perpendicular to the screen and projector, not necessarily parallel to
floor). As the distance between the projector and the screen increases, image size
also increases.

Position
and Mounting
Throw Distance
'

INSTALLATION & SETUP
VistaPro 2000 User's Manual
2-7
Throw distance is roughly equal to the width of the screen multiplied by the type
of lens you are using. For example, if using a 1.2:1 lens, throw distance should
be roughly equal to 1.2
x
the screen width. Once you know your screen size, you
can determine how far away the projector should be:
Table 2.1
Lens Type Approx. Throw Distance
5:1 5 x screen width
1.2:1 1.2 x screen width
1.5:1 - 3:1 1.5 x screen width up to
3 x screen width
3:1 - 7:1 3 x screen width up to
7 x screen width
NOTE: Throw distance is measured perpendicular to the screen and projector,
not necessarily parallel to the floor. It is good practice to simulate the setup with
the projector fully warmed-up to determine the actual throw distance required.
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 ensures that the
image will be rectangular in shape rather than keystoned (having non-parallel
sides). Vertical position can be offset up or down using the vertical adjustment
knob on the front of the projector. The vertical offset range of a projector with a
fixed lens is shown in Figure 2.6. Maximum offset with a zoom lens is 75%.
Figure 2.6. Projector Position and Vertical Offset Range with Fixed Lenses
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
may cause 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.
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 2.7. The
position of the projector and mirror must be
accurately set. If considering this type of
installation, call your dealer for assistance.
Figure 2.7. Folded Optics
The rear panel of the projector has two standard input panels to which you may
connect a variety of sources. The upper right panel (DAT 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 (VID 1) or
S-video (VID 2) and audio from devices such as video tape or disk players.
There are also several optional interfaces available for connecting other sources
(DAT 2). Such an option installs in the upper left panel. See Figure 2.8.
Figure 2.8.
VistaPro 2000
Back Panel
The RGB input (DAT 1) includes BNC type connectors for connection to a
variety of RGB sources. Such sources include VGA, SVGA, Mac, PowerMac,
DEC, Sun, SGI and others. VistaPro 2000 supports multiple sync types: sync-on-
green for data, composite, and separate H & V.
NOTES: 1) 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 2) If you connect a computer directly to DAT 1 you may
experience locking problems due to the different impedance sync output of the

computer. To remedy, use very short (< 3ft) cables and always use an interface
between your computer and the projector.
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 2.9.
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: VistaPro 2000 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, Controlling the Image.
Figure 2.9. RGB Inputs
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 DAT 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 (VID 1) and an S-Video source (VID 2).
If connecting a S-Video source, use the 4-pin mini DIN connector or the Y and C
BNC connectors (luminance and chrominance) — do not use both as input. If

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 VistaPro 2000 (Dat 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 E,
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 2.12). Plug the three-prong end of
the line cord in a grounded AC outlet. Input voltage to the projector must be
between 100 and 240 VAC, 50 or 60 Hz. The power source must be capable of
supplying 1080 watts of power to the projector.
Figure 2.12. Power Connection
WARNING:
Do not attempt operation if the AC input is not within
the specified input range.
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.
VistaPro 2000 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, however it can be done at any
time. See Section 3, Operation for further information.

WARNING
The projector must tilt no more than 45° from
side-to-side to ensure that the lamp
operates properly and safely.
Once the VistaPro 2000 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.
VistaPro 2000 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. See Section 3, Operation for complete display adjustments.
Use RS-232 connections when controlling VistaPro 2000 with a personal
computer with an RS-232 serial interface or when using the projector with a
Marquee switcher. The VistaPro 2000 RS-232 ports are located on the lower

Figure 2.17. Three Networked or "Chained" Projectors
Notes: 1) To avoid damage, connect only properly wired RS-232 serial
communication cables to the VistaPro 2000 RS-232 connectors. 2) It is
recommended that each communication cable be no more than 25 feet in length.
Each projector can be assigned a unique 3-digit projector number (for example,
001). These numbers are particularly useful when you are working with multiple
linked projectors, enabling you to direct commands to a certain projector rather
than broadcast to all projectors. For complete information on how to assign
projector numbers, see 3.7, Controlling System Parameters.
At manufacture every keypad is assigned a default protocol, which is simply a
collection of settings that determine how the keypad operates. Once assigned,
this protocol remains in effect until it is changed — that is, the keypad will
operate as it currently does until you change its protocol.
Protocols are most useful for multiple-projector applications. For example, you
might want to change a keypad protocol if you are working with two projectors
and two remote keypads in the same room and need to control each projector
independently (Figure 2.18). When Keypad A has a different protocol than
Keypad B, each keypad communicates only with the projector having a matching
protocol. Or, if you have a network of two or more projectors connected together
via RS-232 serial ports, you may want only certain projectors to respond to a
wired keypad.
NOTE: Matching the protocol on the projector to that of a keypad is done
through a setting in the VistaPro Plus Preferences menu. See 3.7, Controlling
System Parameters for further information on how to change the projector's
infrared sensor (rear and front) protocol.
A protocol for either type of remote keypad — IR or wired — can be changed
through software commands entered on the keypad. A new protocol set through
software commands remains in effect until the keypad batteries are removed and
replaced (if an IR remote), or until the keypad is unplugged (if a wired remote).
A remote can also be changed manually —you can "hard-wire" new jumper
settings inside the keypad so that they remain in effect until you change the hard-
wiring. Note that a hard-wired protocol can be temporarily overridden by the
software protocol change, effective until the keypad is unplugged and plugged in
again (if a wired remote) or until a battery is removed (if an IR remote).

Figure 2.18. Independent Keypads and Projectors
The standard IR remote keypad or the optional wired remote can be set to one of
two different protocols — "A" or "B". To hard-wire a protocol to "A" or "B" in
either remote, follow Steps 1 through 5:
Step 1
Unplug the keypad from the projector (applies to wired remote only).
Step 2
Unlatch and open the empty battery compartment on the back of the keypad as
shown in Figure 2.19.
NOTE: A wired keypad will open as shown, but there will be a cable passing
through the battery compartment cover.
Figure 2.19. Opening the Keypad
Step 3
Find the 4 jumpers located along the latching side of the battery compartment.
These jumpers set the keypad protocol and other settings so that the keypad
functions in a certain manner.

Figure 2.20. Locating and Setting the Jumpers
Step 4: Set the Jumpers
Set the jumpers as shown in Figure 2.20. Take care to refer to the correct part of
the drawing — standard IR or wired (optional). Use tweezers or needle-nose
pliers to remove and replace each jumper as necessary.
•
J1 jumper: For either remote, set between pins 1 and 2 to set as Protocol
"A". Set between pins 2 and 3 to set as Protocol "B".
•
J2 jumper: For either remote, set between pins 2 and 3 as shown; otherwise,
the projector will not respond correctly to keypad commands.
•
J3 jumper: For the IR remote, make sure that the jumper is set between pins
2 and 3 as shown. For the wired remote, make sure that the jumper is set
between pins 1 and 2 as shown.
•
J4 jumper: For the IR remote, make sure that the jumper is set between pins
1 and 2 as shown. For the wired remote, make sure that the jumper is set
between pins 2 and 3 as shown.
Step 5
Replace battery compartment cover. Plug into projector (wired keypad only) and
test.
NOTE: Although they are similar, a VistaPro IR wired keypad cannot be
converted into a remote keypad, nor vise versa.
SHORTCUT METHOD:
You can also issue software protocol settings through the keypad. These
software commands will be lost when the keypad is either unplugged or when a
