The smallest discernible element of data from a computer-generated image.
The phase of the pixel sampling clock relative to incoming data.
The frequency of the pixel sampling clock, indicated by the number of pixels per
line.
The projector is at presentation level when an image from a source is displayed
without the presence of a slidebar, menu, pull-down list, or error message. For
example, if a help page is displayed, the projector is not at presentation level.
The distance between the projectors front feet and the screen. Also called
Throw Distance”.
The type of code format utilized by IR keypad(s). The default from manufacture
is Protocol A. By using two different protocols, two projectors may be used side
by side while being controlled independently by their remote IR keypads.
A selectable menu item that unfolds into a list of options pertaining to a given
parameter.
A translucent panel for screen projection. Incident light travels through the
incident surface of a rear screen and forms an image on the other surface.
The maximum number of alternate white and black horizontal lines that can be
distinguished on a screen when a photographic target is placed between the lens
and a light source, and illuminated by that light source.
The maximum number of pixels that the projector can display horizontally and
vertically across an image.
The minimum time required for a CRT projector to move the position of the
scanning spot from the right edge to the left edge.
The time required by the video amplifier of the projector to increase its output
from 10% to 90% of the maximum value.
The video output (analog or digital) of most computers. Analog RGB video can
have 3, 4, or 5 wires — one each for red, green, and blue, and either none, one or
two for sync. For three-wire RGB, the green wire usually provides sync. (See
TTL Video).
An asynchronous data transmission standard recommended by the Electronics
Industries Association (EIA). Also called serial communication.
The output from certain video tape players and video equipment. S-Video
separates sync and luminance from color information, typically producing a
higher quality display than composite video.
The horizontal or vertical frequency at which images are generated.

							GLOSSARY
VistaPro 2000 Users ManualA-5
A video output format of some video tape and disk players (used primarily in
France). SECAM (Sequential Couleur á Mémoire) signals are similar in
resolution and frequency to PAL signals. The primary difference between the
two standards is in the way color information is encoded.
A slidebar is a graphical display of an adjustable setting. The numerical setting
usually represents a percentage.
The device, such as a computer or VCR, connected to the projector for display.
A source is identified as  
 ,   ,   or   , or as other user-defined
numbers. Sources have corresponding source setups recognized by the projector.
A number from 1 to 99 that uniquely identifies a specific source.
A collection of measurements stored by the projector for a given source and/or
projector, including frequencies, pulse width, polarity, syncs, source number and
location, user-adjustable display settings, etc. Source setups enable the projector
to automatically recognize and properly display input from a variety of sources.
The diameter of the smallest dot that can be generated by a CRT projector.
VistaPro 2000 has a fixed spot (pixel) size.
A signal selector that can be connected to a projector for the purpose of adding
more sources.
This term refers to the part of the video signal that is used to stabilize the picture.
Sync can occur in three forms:
1) Composite sync:  the horizontal and vertical components are together on
one cable.
2) Sync-on-green:  the sync is part of the green video.
3) Separate sync or H.SYNC and V.SYNC:  the horizontal and vertical
components of the sync are on two separate cables.
The duration of each sync pulse generated by a computer. The sync width is part
of the blanking time.
A type of RGB video with digital characteristics.
A wire connecting a single video source to a display device, such as a projector,
must be terminated by a resistance (usually 75S for video).
The distance between the front feet of the projector and the screen. Also called
Projector-to-Screen Distance”.
Balance of red-to-green necessary for realistic representation of NTSC signals.
The ability of a projector to synchronize to inputs with frequencies within a
specified range.
The frequency at which images are generated. Vertical frequencies vary amongst
sources. Also called vertical scan rate. SECAM

The difference between the vertical height of the projector lens and the vertical
height of the display.
The signal that is used by display devices (such as projectors) to generate an
image. This term also refers to the output of video tape/disk players and
computers.
A device that converts NTSC 3.58, NTSC 4.4, PAL, PAL-N, PAL-M or SECAM
to RGB video.
A specific type of video signal, such as NTSC, PAL, SECAM. VistaPro 2000
can automatically recognize and display the standard and display accordingly.
Screens do not reflect equally in all directions. Most light is reflected in a
conical volume centered around the line of best viewing. Maximum brightness
is perceived if you are within the viewing cone defined by the horizontal and
vertical viewing angles.
The color temperature of white used by the projector.
The area of an image that is white only. For example, a full white field is an
image that is white everywhere. A 10% white field is a white area (usually
rectangular) that occupies 10% of the image; the remaining 90% is black.
A high-end signal suitable for broadcast. YUV video (also called component
video) by-passes the VistaPro 2000 video decoder.

Optional Input Modules
VistaPro 2000 Users Manual E-1
There are many optional input modules and accessories available for the VistaPro 2000. Contact your dealer or
Electrohome for a complete and up-to-date listing.
The Marquee Signal Switcher is a rack-mountable signal selector which can
extend the number of selectable inputs by the VistaPro 2000. Connected to the
projector RGB interface (DAT 1), each switcher adds 8 more sources to the
system. Other switchers can be connected to the first, with each input selectable
through a keypad. Switcher inputs can also be selected by pressing the
appropriate front panel push-button.
Features
à can be used with VistaPro 2000 and other projectors
à simple push-button control
à easy to see, illuminated indicators
à 9 expansion slots for interface modules
à RS-232 serial interface
à input for a wired remote keypad
à universal power input
à up to 9 switchers can be ganged together for use with the projector
The RGB500 Input Module may be installed in a VistaPro 2000 projector, a
Marquee signal switcher, or a Marquee Case/Power Supply. The module
receives analog RGB input signals from computers or other RGB source devices.
