CHAPTER 2: Introduction
2. Introduction
Fig. 2-1. The Projection Panel on an Overhead Projector.
2.1 Description
For remarkably impressive
presentations, use the Real Color
or Monochrome 16 LCD Projection
Panel. The Panel, which projects
16 real colors or 16 shades of grey,
delivers the computer compatibility
and ease of use you never thought
possible in an LCD projection panel.
Fig. 2-1 illustrates the Panel coupled
with an overhead projector.
6
REAL COLOR AND MONOCHROME 16 LCD PROJECTION PANELS
The Projection Panel is easy to
use. Simply connect the Panel to a
computer graphics card and place
the unit onto an ordinary overhead
projector. The data and graphics
normally displayed on the computer
monitor will be projected in images
that you can easily see in typical
room lighting. The Projection Panel
has a temperature-regulating fan,
which works with the heat-producing
overhead projector, to hold the
liquid crystal display (LCD) to the
optimum temperature. You can use
the Projection Panel on a wide range
of overhead projectors rated up to
650 watts.
The Projection Panel, with a
640x480 pixel display, is compatible
with the Macintosh®series and
Macintosh II series; with Apple®IIGS
RGB; with IBM®PC and compatibles
in CGA, EGA, and VGA modes, and
with the IBM PS/2®with VGA or CGA.

CHAPTER 2: Introduction
2.3 General Guidelines
Follow these guidelines when you
use the Projection Panel.
• Be sure the Projection Panel
is on whenever the overhead
projector is turned on.
CAUTION
If the Projection Panel is not
on when it is on top of an
operating overhead projector, the Panel could
sustain damage.
• Do not use the Projection Panel
for extended periods of time on
an overhead projector known for
discoloring or melting standard
transparencies.
• When you use the Panel with a
high-wattage projector or if you
notice extreme discoloration of
the Panel, periodically remove
the Panel from the overhead
projector to allow it to cool.
• The bottom of the Panel can
become very hot to the touch
after use. Be careful to let the
Panel cool before lifting it.
• Do not block the Projection
Panel fan or free air movement
under and around the Panel.
Air flows from back to front.
• Turn the overhead projector off
and unplug the Projection Panel
when not in use.
• Handle the Projection Panel as
you would anything made of
glass. Be especially careful not
to drop it.
• You can easily clean the
Projection Panel with standard
non-abrasive glass cleaner. Apply
the cleaner to the cleaning cloth
and then wipe the glass surface
lightly. Do not use excessive
amounts of liquid or pressure on
the top or bottom optical panels.
• Avoid scratching the Projection
Panel surface with sharp metal
objects. The top surface is made
of glass or a scratch-resistant
hardened polymer. If you need
to clean the surface, use normal
glass-cleaner solution. Do not
use abrasive cleaners, solvents,
or other harsh chemicals.
• Avoid leaving the Projection
Panel in direct sunlight or
extreme cold for extended
periods of time.

Showing Cable Connections.
3.1 Setup Instructions
This chapter explains the
connections you must make between
the three pieces of equipment you
will be using—the Projection Panel,
your computer, and monitor. Be
sure to follow the instructions for
your type of computer.

CHAPTER 3: Installation
3.1.1 C
ABLES
Three cables are supplied with the
Projection Panel:
1. A Macintosh II/Macintosh
LC/Apple IIGS loop-through
cable
2. A VGA/MCGA loop-through
cable
3. A loop-through cable for EGA,
CGA, or Macintosh video
Fig. 3-2. Cables.
The cables that come with your
Projection Panel are used to connect
the computer’s video port to the
Projection Panel and the monitor.
Each of the three cables has a 26-pin
connector for the Projection Panel,
a connector matching the video card
and a connector for the monitor.
The Projection Panel receives the
computer’s signals, amplifies the
signals, and sends them out to the
monitor.

You are going to make eithertwo or
three connections. You will connect
the computer’s graphics card to the
Projection Panel, the Projection
Panel to the wall outlet with the
power supply, and, optionally, the
Projection Panel to the computer’s
monitor.
The steps you need to follow are
given in Section 3.1.3. Illustrations

ANEL FORPROJECTION
To set up the Projection Panel for
projection, follow these steps:
1. Set up your overhead projector
and plug it into the wall outlet.
Turn it on to be sure it is
working properly and position
it so it projects onto the screen.
2. Place the Projection Panel on
the overhead projector so the
connectors and controls are on
the right side of the projector
as you face the front of the
projector.
3. Connect power to the Projection
Panel, but do not connect a
video signal yet. This will bring
up a test pattern.
Move the Projection Panel on
the projector until the lines
are solid rather than rainbows.
Adjust the tint for the best color
saturation or the contrast for the
best greyscale.

Plug the monitor to the short
end (marked Monitor) of the
Projection Panel cable to the
computer monitor.
7. Plug the long end of the
Projection Panel cable (marked

to the computer’s video port.
8. Tighten the thumb screws on
the cable connectors to ensure
proper grounding.
Refer to Appendix A for additional
important information on how to
properly place a Projection Panel
on an overhead projector.
4. Follow the instructions in this
table to select the proper “Y”
cable for your computer:5.
Connect the 26-pin end (marked
LCD) of the “Y” cable to the
Projection Panel.

3.2 Connecting the Projection Panel
to a Desktop Computer
Figure 3-4 shows how to connect the
Projection Panel to typical desktop
computers, which include CGA,
EGA, VGA, Macintosh II, and
Macintosh LC setups.
All cables are labeled (for
example, LCD, Monitor, VGA, etc.)
to indicate where they connect.
