Product Introduction
Introduction
The WN-5230A-S is a 52-inch (132 cm) diagonal 800 x 600 (SVGA) resolution
rear-projection display system designed around Texas Instruments’ proprietary
Digital Light Processing™ (DLP)™ technology. The display features low power
consumption, excellent brightness and uniformity, with a sharp true-to-life color
spectrum.
The display utilizes the same modular form factor as the company's other
award winning, rear-projection display products, while providing the benefits of
DLP technology. The WN-5230A-S offers consistent color and brightness
uniformity, without the color drift, image retention, or convergence problems
associated with CRT based rear-projection systems.
The WN-5230A-S provides the same high image quality, reliability, light weight
and brightness levels typical of Clarity display products.
Features
• optical resolution of 800x600 pixels
• low 220 watt power consumption
• long 6,000 hour median lamp life

Power
Make sure that any power cord substituted for the power cord originally
supplied with the display is compatible with the nominal power source used
with the WN-5230A-S.

WN-5230A-S VideoWall User’s Guide
Power Consumption
Typical power consumption of the WN-5230A-S is 160 Watts, but the
maximum potential of 200 Watts should be used for calculating the load on
the power source. At 200 Watts the current draw is approximately 1.7 Amps
at 115 VAC (0.9 Amps at 230 VAC).
Voltage Range
The WN-5230A-S will operate between 100 and 240 volts AC at 50/60Hz.
Since the power module is auto ranging, there is no manual selector switch.
The main power switch on the power module also acts as circuit
breaker. If power to the display is lost, check the power/breaker
switch by turning it off and then back on.
The power switch is a lighted switch. When it is lit, it indicates that the
AC power is applied and the power switch is on.
WARNING
WARNING
Displays that are intended for 240V configuration must have a
properly rated power supply cord and attachment plug supplied
by the installer.
If extension cords are used for power, ensure that only 3-prong
grounded cords sized to handle system power requirements are
used. Using the wrong-size extension cord can cause a firesafety hazard and can reduce the voltage available to the WN5230A-S. If the extension cord is warm to the touch it is too small
and should be immediately removed from operation.
WARNUNG
Falls für die Stromversorgung Verlängerungskabel benutzt
werden, achten Sie bitte darauf, daß nur geerdete, dreipolige und
für die vorgesehene Leistungsaufnahme ausgelegte Netzkabel
benutzt werden. Die Verwendung eines unterdimensionierten
Verlängerungskabels stellt eine potentielle Feuersgefahr dar und
kann dazu führen, daß die für den WN-5230A-S Video-Monitor
verfügbare Spannung zu gering ist. Falls das Verlängerungskabel
sich fühlbar erwärmt, heißt das, daß das Verlängerungskabel
unterdimensioniert ist. Es muß dann sofort aus dem Verkehr
gezogen werden.
WARNING
Hazardous voltages inside the display and power module can
shock, burn and cause death. Only the WN-5230A-S lamp and
air filter are user serviceable. Always turn off and disconnect
power before servicing these items. Refer all other service to a
qualified service center. Failure to do so could result in electrical
shock, ultraviolet radiation burns, contact heat burns, serious
injury, or irreparable damage to the WN-5230A-S and may void
your factory warranty.

WARNUNG Im Innern des Monitors liegt gefährliche Hochspannung an. Falls
Sie unter Hochspannung stehende Teile berühren, können Sie
einen elektrischen Schlag erhalten bzw. Verbrennungen oder
sogar den Tod erleiden. Im Innern befinden sich keine Teile, die
von einem Laien gewartet oder repariert werden könnten.

Temperature and Humidity
The WN-5230A-S is designed to operate over an ambient temperature range
of 0° to 35° C (32° to 95° F) and between humidity of 20 to 80 % R.H. noncondensing.
The air that cools the display and the warm exhaust air is passed through the
back of the WN-5230A-S. This area should not be blocked. If the display
becomes overheated, permanent damage to the product may result.
Some types of environmental lighting, such as incandescent, or high intensity
discharge lamps such as metal halide or mercury vapor lamps, create high
temperatures and this can cause excessive heating of the WN-5230A-S. The
displays should be positioned far enough away from high-temperature lights
to prevent heat buildup.
Nearby heat sources can cause high operating temperatures in the WN5230A-S. Minimize the display’s exposure to heating ducts, radiators, or
other external heat sources.
Flooring
A typical WN-5230A-S weights approximately 120 lbs. (55 kg). Before
installing the WN-5230A-S, determine the structural integrity of the flooring
where it will be used. The floor should be level and strong enough to support
the combined weight of the number of displays and other equipment used in
the installation. Take special care when installing a WN-5230A-S in a wall
configuration on a temporary structure such as a stage floor, where the
flooring could bend or collapse under the weight of the installation. The
maximum number of WN-5230A-S’s stacked vertically in a wall configuration
resting on a temporary floor should be no more than 4.
Clearance
To allow proper cooling, the minimum required clearance to the rear of the
Unit is 6 inches. However, the displays are serviceable only from the rear, so
you need enough space behind the display to stand and work.
February 03

WN-5230A-S VideoWall User’s Guide
If installed in a video wall configuration, a minimum of 12 inches to the ceiling
from the top of the highest display is needed if the units are installed from the
front.
Cables and Signals
Video connections from the signal source to the display depend on the type
of signal supplied by the source. The compatible data inputs are: PC
800x600 (SVGA), PC 640x480 (VGA), MAC 800X600 or 640X480, 31.5 kHz
and 15.75 kHz (progressive scan) RGBS video, composite video, and
S-video.
The Loop-Thru video output uses a standard 15 pin VGA type connector for
output to an external computer monitor or to another WN-5230A-S. The
format of the Loop-Thru video is same as the source video.
The video cables used should be high quality and shielded to insure the best
image quality when displayed. VGA and MAC will have RGB with separate HSync and V-Sync. RGBS video will come out RGBS with the composite sync
on the connector’s H-Sync pin. RGB Sync on Green sources will loop-thru
RGBS-Sync on Green. Displays with the VIM-300 option also have
Composite Video and S-Video loop-thru connectors.
Using poor quality cables can lead to picture noise, jitter and crosstalk.
Even good quality cables that are longer than 10 feet may produce
noise and jitter in the image if the source signals are not amplified.
Control data enters the display via the RS-232 In connection, and is supplied
to an adjacent display (if used) via the RS-232 Out connector. High quality
shielded cables designed for RS-232 communication should be used to
ensure proper data transmission and control. The wiring of the RS-232
cables must be straight through (pin 1 to pin 1, pin 2 to pin 2, etc…) and not
wired for “null modem”.

Tools Required: 3/8-inch nut driver, #2 Phillips screwdriver
Optical Alignment means to adjust the size and position of the image and to
correct for keystoning and rotation. Before installing a display, check it to
verify that the image is optically aligned.
When thinking about the optical calibration process, here are some things to
remember:
• The critical dimension during calibration is the distance from the
projection lens to each corner of the screen. If these distances are
equal, from lens to mirror to screen, the image will be a rectangle.
Optical Alignment
• The light path from lens to screen is expanding. If the path of one corner
is a little longer, that part of the image will expand more; if shorter, that
part will be smaller.
• Work on one thing at a time and in this order:
1. Make the image rectangular. Don’t worry at first about size or
placement. Just make it have four square corners.
2. Adjust rotation, so that the edges of the image are parallel with the
edges of the screen.
3. Adjust size, making the image fill the screen. Hide one pixel at
each edge for acrylic screen, two pixels at each edge for glass
screens.
4. Adjust position, left and right, up and down.
• In most cases, only slight adjustments are required, usually just position.
Don’t try to adjust anything that doesn’t need it.

If the image needs only a small adjustment, skip down to Adjust the Image. For an
image that is way out of alignment and that needs major adjustment, start with
everything in a “normal” position.
• Remove the screen and check that all the pointed alignment bolts at
the sides of the chassis are at the same distance out. Put the shipping
shim behind each bolt and tighten the bolt to it. (Later, when building
a wall, make sure that the main chassis of the cubes are aligned. It is
a mistake to move the screens in and out a great distance with the
pointed alignment bolts to compensate for main chassis that are not
even with each other. Moving these bolts a lot will change the image
size, because the lens-to-screen distance changes.)
• Each corner of the optical engine mount should start at the same
distance out. Factory default is 3 cm, but any distance near this
amount will do a good job. Make a block of wood that is 3 cm thick
and use it as a gauge at the four corners of the metal engine mount.
Then adjust S1, 2, 3, and 4 to make the engine mount just touch the
block.

Adjusting the Image
There are four nuts on the engine mounting plate,
S1, S2, S3, and S4. Always adjust these in pairs and
turn them equal amounts.
Figure 1. Diagram of optical engine,
mirror and screen as seen from the side.
Keystone, top wider
To fix this, loosen nuts S1 and S3 in equal
amounts to make the top smaller. This will lower
the image on the mirror, shortening the distance
to the screen for the top, thus making it smaller.
The whole image will be lowered, but you can fix
this later with the lens adjustment.
Keystone, bottom wider
To fix this, tighten nuts S1 and S3 equal amounts to
make the top larger. This will also raise the image, so
you will have to use the lens adjustment later to lower
it.
Keystone, left side wider
To fix this, loosen the lock down nuts, NL1 and NL2.
Then loosen N1 or tighten N2. Retighten NL1 and
NL2 to lock it again.

Keystone, right side wider
Loosen the lock down nuts, NL1 and NL2. Then
tighten N1 or loosen N2. Retighten NL1 and NL2.
Rotation, clockwise
Loosen S3 and S4, or tighten S1 and S2, equal
amounts to rotate the left side of the image down.
Rotation, counterclockwise
Tighten S3 and S4, or loosen S1 and S2, equal
amounts to rotate the left side up.
Size
To increase image size, loosen N1 and N2 together.
To make the image smaller, tighten them both.
Before adjusting N1 and N2, loosen the locking nuts
NL1 and NL2 (lock down nuts).
Right, left
Loosen HL1 and HL2 to unlock horizontal movement
of the metal frame. Tighten or loosen H1 and H2 in
equal amounts to move the image sideways. Then
tighten HL1 and HL2 again.
Up, down
A D-shaped shaft on the optical engine (V in the
diagram) moves the image straight up and down.

Mechanical Setup
The mechanical setup is broken down into three processes - the physical
assembly of the wall, the attachment of cables to each display and the setting
of each display’s number, or address, in the wall.
Mechanical Setup
CAUTION
You will need these tools:
• a large, flat blade screwdriver
• an SAT-5200 Screen Alignment Tool (two of these tools makes
• black cloth tape
• a tape measure (inches or centimeters)
• 1/2” open-end wrench, a 1/2” deep-well socket, or an adjustable wrench
• 5/64” Allen hex wrench

the frame it is held in, an assembly which
is about 3” (7 cm) thick. The screen
attaches to the second part, an adapter
plate which is about 2” (5 cm) thick. The
adapter plate is mounted on the front of
the display unit.

During the alignment process, you
remove the screen from the adapter plate,
then adjust the adapter plate to make its
corners square and align correctly with its
neighbors. Then the screen is re-installed
and adjusted in or out.
Mechanical alignment is critical, and the
larger the video wall, the more precisely
each unit must be aligned to produce a
good looking image. The outcome of this
alignment process is partly dependent on
how flat the floor is, but it is mostly
dependent on how tightly the displays are
fitted to each other.

Basic Steps for Alignment
This is a summary of the steps necessary to build a video wall and align their
screens. This is a summary only. The details on how to perform each step
follow the summary.
1. Remove the screens from all the display units.
2. Build the video wall.
3. Start with the display unit in the center of the bottom row. Square its
adapter plate.
4. Using the Alignment Tool, working along the bottom row in both
directions from the squared adapter plate and align each of the other
Adapter Plates to its neighbor.
5. Align the adapter plates on the rest of the rows, working upward, to
the adapter plates in the bottom row.
6. Hang the screens on the bottom row and adjust them in or out so the
front surfaces (the screen faces) are flat with each other. Then do the
rows above.
7. Put retaining screws in the top row and cover any holes and seams
with black tape to prevent light leaks.
Side to side bolts and wing nuts hold the displays together.
