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 Folded Optics

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:
Y to 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 Composite Video

connecting a composite video source, use the Composite BNC connector or the
RCA phono jack — do not use both as input. See Figure 2.10.
NOTE: If using the loop-through feature for composite or S-Video input, see
Video Termination in 3.7, Controlling System Parameters.
Figure 2.10. Composite and S-Video Inputs
If you want to use an extra video source in addition to the video source(s)
connected at Vid 1 and/or Vid 2, connect either a Composite or S-Video source
to Dat 1 as shown in Figure 2.11.

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. Other inputs

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 VistaPro 2000
projector must be parallel to the
screen to prevent keystoning. To
make small corrections to the
projectors level, rotate each leg as
necessary to raise or lower.
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
right portion of the projectors rear control panel as shown in Figure 2.13.

Figure 2.13. RS-232 Serial Port Connections
NOTES: 1) The VistaPro 2000 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.  3) The spare port is used for de-bugging and
testing by qualified service personnel only.
You may wish to use a computer rather than a keypad for controlling the
projector and for performing other special functions. Connect an RS-232 serial
communication cable between the computer and the projector serial port labeled
NETWORK IN (Figure 2.14). Then set the baud rate to match that of the
computer. Changing the baud rate is described in 3.7, Controlling System
Parameters.
Figure 2.14. RS-232 Serial Port Connection to a Computer
Note: PC software is required for computer control. Contact your dealer or
Electrohome for details.
You may wish to use one or more external Marquee switchers or third-party
switchers in order to significantly increase the number of sources you can use.
Connect an RS-232 serial communication cable between the switcher and the
projector serial port labeled SWITCHER (Figure 2.15). This port is
permanently set at 9600 baud. If using a computer

To control multiple projectors with a computer/controller, chain the projectors
together by connecting the NETWORK OUT connector of the first projector
(already connected to the computer/controller) to the NETWORK IN
connector of the next projector in the chain (Figure 2.16).
Figure 2.16.  Adding Another Projector
Continue connecting projectors in this way to the last projector in the chain, so
that only the last projector has an empty NETWORK OUT connector. See
Figure 2.17.
Communication parameters such as baud rate must be set to match the particular
controlling device—refer to the documentation that came with the controlling
device in order to determine the proper baud rate. See 3.7, Controlling System
Parameters if you need help changing the projector baud rate from its default of 9600. If using multiple

 projectors

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 projectors
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). Projector Number

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 2.20. 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
