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
• light weight – 120 pounds (55 kg)
• thin – 28.9 inches (73.4 cm)
• excellent brightness and uniformity (no “hot spots”)
• consistent colors displayed on adjacent modules
• no color drifting
• no convergence problems

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
12
Page 23
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”.

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.

Figure 1. Optical Engine adjustment points.
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

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

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

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.

Alignment Procedure in Detail
Read through all the detailed parts of each numbered step before starting it.
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. This
will be the Base Unit. Align the
Base Unit’s adapter plate. (If the
A. Look down on the top of the screen and locate the
two retaining screws. Remove these screws, using
the 5/64-inch Allen hex wrench, and set them
aside.
B. Grab the sides of the screen, or use the finger
holes, and lift it up about half an inch (1 cm), and
remove it from the adapter plate. Set it aside.
A. Assemble the lower row first. Line up the legs for
the bottom row as straight as possible. Insert a
¼” x 2½” bolt through the holes as shown in
Figure 1. Tighten a nut securely on this bolt, but
not so tight as to bend the legs. From one end of
the bottom row, look along the row to see that all
the units are aligned, that the line of the front of
the display units does not curve forward or
backward, up or down. The straighter the first row,
the better the finished wall will be. And the easier
it will be to keep it straight as you build.
B. Secure the legs to the floor. Use the tapped 5/16-
18 holes in the front and rear of the legs. You can
put an eye-bolt in this hole and secure it to the
floor with a lag screw. Or use angle bracket,
screwed to the floor and bolted to this hole in front
and rear. Or use the optional BAS-5200 base,
securing it to the floor and putting the lower row of
displays on it. (If the BAS-5200 is used, remove
the adapter plate before you put the unit on the
base.) Stack the next higher row. Sliding the legs
of each display into the mating sockets of the
display in the first (lower) row.
C. Insert a bolt (supplied). Insert a bolt through the
hole in side wall of the lower unit and into each leg
of the unit above. Tighten a nut on this bolt to lock
the units together. See Figure 1 above. Tighten all
the bolts after you have checked for straightness,
as in Step A above.
D. Continue with higher rows of displays. Lock each
display to the adjacent displays after the row
above it (if any) has been installed. Check for
straightness on each row.
E. For added stability, use the tapped holes in the
rear of the legs of the upper units to fasten to a
solid support, such as a structural wall. The
threaded inserts in each leg are female 5/16-18
UNC.
F. Check that all displays in the video wall are locked
together. And straight.
A. Look at the sides of the Adapter Frame. (See
Figure 3, below.) Starting at the top edge and
moving down you will see a large Locking Screw,
a
ointed Alignment Bolt, and an Alignment Hole.

bottom row has an even number of
display units, choose either middle
one. This step can be done before
the wall is built, if necessary.)
Near the middle of each side is a threaded hole
for the Alignment Tool’s spring-loaded screws.
(Do not attach the Alignment Tool yet.) At the
bottom of the side notice the Alignment Hole, the
Alignment Bolt, and the Locking Screw.
B. Look at all the Alignment Bolts of all units. They
should all be the same distance out. The factory
ships the display with a “shipping shim” behind
this bolt. If you have to adjust these bolts, you
should remove this shim. Save it. Use it later, if
you need to ship the units. When you ship
displays, always have the Alignment Bolt either
tighten onto the shipping shim, or tighten down
completely.
C. Check to see that the Adapter Frame of the Base
Unit is centered on the chassis. If the frame is not
centered on the chassis opening, for instance, if it
is offset to the left, then all the other frames will
have to be offset in this same direction. It is best if
this first frame is nicely centered on its chassis
opening.
D. Check to see that all the Locking Screws are tight.
E. Measure the opening diagonally, from corner to
corner in both directions, and compare the results.
Be sure to measure from exactly the same points
each time. An accuracy of 1/32
nd
inch (0.8 mm) is
necessary for most applications, but the more
accurately you can do this, particularly in the
bottom center unit, the better the video wall will be
aligned and the better the picture will look.
F. If the two measurements are the same, you have
a rectangle with perfectly square corners,
4. Working along the bottom row
in both directions, align each of
the adapter plates, using the
Alignment Tool.
and you may go on to Step 4.
G. If the two measurements are not the same, within
nd
1/32
inch (0.8 mm), the frame is not a rectangle
with perfectly square corners, it is a parallelogram.
Loosen the top Locking Screws on each
side. Move the adapter plate left or right a bit and
tighten the screws. Measure the diagonals again.
Repeat this process until you are satisfied that the
two diagonals are the same. This means the
adapter plate is a perfect rectangle with square
corners.
A. Now that the center unit adapter plate is squared,
align one of its neighbors in the bottom row.

B. The diagram above shows the order in which you
should align the displays in a typical video wall.
(Note: This is not the same as the Unit ID
address of the display units.)
C. The Alignment Tool fits over the seam of two
adjacent adapter plates. The Tool has six guide
pins, three on each side, and four spring-loaded
screws, two on each side. (Only two of the springloaded screws, one on each side, will be used at a
time.)
D. Position the Alignment Tool between the two
displays. One of these (#1) is already square and
the other (#2) is about to be aligned. Fit the tool
into display #1 first and attach it with the lower
spring-loaded screw. The guide pins should go
into the Alignment Holes in display #1.
E. Loosen the two Locking Screws in #2 on its right
side under the Alignment Tool and move the
adapter plate of display #2 until the guide pins go
in the Alignment Holes. Secure the Alignment
Tool to #2 with the spring-loaded screw. Tighten
the two Locking Screws on #2 under the
Alignment Tool. (Do not be concerned about the
units in the row above at this time.)
F. With the Alignment Tool still in place, check
display #2 for squareness by measuring the
diagonals. Loosen the Locking Screws on #2 that
are on the other side from the Alignment Tool, and
adjust adapter plate #2 until it is square-cornered
rectangle.
G. When you are satisfied that display #2 is aligned
to display #1 and it has perfectly square corners,
remove the Alignment Tool. (If you have two
Alignment Tools, leave this first one in place, and
put the second on the other side.)
H. Go to the display on the other side of the center
display (#3) and align it to the center display,
following the steps 4.C through 4.G.
A. Start with the display above the Base Unit. Align
display #4 to display #1. Put the Alignment Tools
on either side of the Base Unit, #1. The u

guide pin should now fit the bottom Alignment
Hole of #4. Loosen the bottom Locking Screw in
#4 and make it fit. Do the same on the other side,
moving the Alignment Tool, if you have only one.
B. Measure the diagonals of #4. Loosen the top two
Locking Screws and make its corners square,
then tighten the screws.
C. Continue with display #5, working your way up the
video wall to the top.
D. When you have completed the inverted-T, use
these as a frame and align the other units to it,
working from the lower rows upward. For each
display, you should be sure it is the correct
distance vertically and horizontally from all its
neighbors and that each unit’s diagonals are
equal.
A. Hang the screens on the bottom row. Be sure the
finger holes are on the top of each screen. When
each screen is seated, pull on it slightly to make
sure it is secure at both the top and bottom.
B. Notice the seams. Are the two screens flush at
each seam? If not, note how much you will have
to adjust one of the screens to make it flat and
flush with its neighbor. Measure this amount, but
be careful not to scratch the screens. Also, sight
along the row from the end. Look down the groove
on the top of the screens. This helps to prevent

where the corners match,
but the screens are not flat. Make a diagram of the
video wall and note how far to move each corner
of each unit in or out. Try to get the wall flat within
1/32” inch (0.8 mm)
C. Remove the screens again.
D. Working from your notes, adjust the pointed
Alignment Bolts with the ½-inch wrench. Looking
at the display from the front, each complete turn of
the bolt CW (clockwise) pulls the corner of the
screen IN (away from you) by 1/32nd of an inch
(0.8 mm).
E. Hang the screens again and check your work.
F. With the screens in place on the bottom row, put
the screens on the next row above. “Flatten” this
row in the same way, paying attention to how
these fit with the bottom row as well as with their
neighbors to the left and right.
A. When all the screens are aligned with each other
to make a flat, square video wall, put the screws in
the top row of screens to hold them in place.
B. The finger holes and the space between the
screen and the adapter plate can be a source of
light leaks, allowing stray light to hit the back of the
screen and wash out some of the picture. To
prevent this, cover the finger holes in the top row

does a nice job of this. Masking tape is sometimes
difficult to remove cleanly. You can check for light
leaks during the video setup process. Select
“Curtain” from the main menu and verify that the
whole screen is black. It is best to do this in the
actual lighting that will be on when the wall is
used.

Input Level
When the black and white levels are correctly set, the display will know
what the absolute minimum and maximum signal amplitude is that the
source is sending to it. The procedure for Input Level adjustment, and
the menus for it, are different for computer sources and video sources.
You must adjust input level for each source that is connected to the
display. Even if two similar sources are being used, such as two
different SVGA sources, the input levels must be adjusted for the
source that is connected at this time. When the other SVGA source is
connected, the levels must be readjusted to match the new source. If
the sources are connected to different inputs (SVGA, MAC, RGBS) then
each source’s Level can be set and saved separately in memory,
because there is a different memory for each source-mode
combination.
For all sources except composite and S-video, the input
Black Level must be adjusted to match the source before
adjusting the input White Level.
Note: Do not use Black Level Adjust and White Level Adjust to color
balance the displays. Matching the displays so they all produce the
same colors is done in a later step called Color Balance. Color Balance
and Level Adjust are entirely independent of each other. Level Adjust
must be done with external video signals. Color Balance should be
done with internally generated patterns.

Color balancing compensates for the differences in brightness of all
display units in a video wall. You only need to do this once, as color
balance is the same for all sources. The color balance information is
February 03
42
Page 53
WN-5230A-S VideoWall User’s Guide
saved in memory in only one location, not for each source. However,
when a lamp is changed, you should color balance again.
The goal of color balancing the displays is to match the brightness
and white “color” of all the displays in video wall to each other, and
then match the intermediate gray shade. Therefore, color balancing is
accomplished with all displays turned on in the finished video wall. (If
you have only one unit, color balancing is not very important.) Do not
start color balancing until all lamps have been on for at least five
minutes.
The color balance menu provides control over the individual RED,
GREEN, and BLUE settings to balance the white color, as well as an
ALL adjustment to control the overall luminance by changing all three
colors together. Similar control for the RED, GREEN, and BLUE
settings is provided to adjust the balance of the gray shades without
affecting the white balance.
The down arrow key moves the cursor from All to Red, Green, and
Blue in the White column, then to All, Red, Green, and Blue in the
Gray column, then back to All in the White column again. The left/right
arrow keys increase and decrease the brightness number. It is a
common mistake to use the left-right arrow buttons to try to move the
cursor between columns. Doing this simply changes the currently
selected value.
For white balancing
, the individual RED, GREEN, and BLUE color
selections have a number between 0 and 31. Zero is the darkest and
031 the brightest.
For gray balancing
, the individual RED, GREEN, and BLUE balance
settings have a number associated with them between 0 and 7. Zero
is the darkest and 007 the brightest.
The following chart shows the relationship of the menu item
adjustments.
Color Increase will: Decrease will:
All Increase the overall luminance
Red Change white toward red Change white toward cyan
Green Change white toward green Change white toward magenta
Blue Change white toward blue Change white toward yellow
Note: If one color needs to be increased, but that color is already as high as it can go, then the
other two colors can be decreased.
Use the White and 50% Gray internal Test Patterns from the Misc
Control menu, not an external pattern.

On each display in the video wall, open the Misc Control menu,
select Test Pattern and choose White.
Press the Color button on the remote control, or choose Color
Balance from the main menu and press Enter.
Adjust the WHT setting of all the displays to 031; adjust the GRY
setting of all displays to 007.
The least bright display is already as bright as it can be. This display
will serve as a baseline to which the other displays will be adjusted.
Note: The baseline display does not have to be the middle one. It
should be the darkest one, wherever it is in the wall. The darkest
display is called the “baseline” display.
Select one of the displays next to the baseline display. This will be
called the “variable” display. Turn off the Color Balance menu to all
displays except the variable display. In the Color Balance menu on
the variable display, highlight the arrows under the Wht. Use the left
arrow to reduce the brightness until the variable display is the same
brightness as the baseline display.
On the variable display, adjust the amounts of RED, GREEN, and
BLUE in the white (Wht) column to achieve the best match in color
and luminance to the baseline display.
If a color needs to be increased, but that color is already as high as
it can go, then the other two colors can be reduced. For instance, if
you need the white to be more red, but red is already at 031, reduce
the green and blue. This will make the display look more red.

When the variable unit matches the baseline, it can serve as a new
baseline unit for its neighbors. Continue to work outward from the
original baseline display, one cube at a time. Do not go to the next
step of adjusting for Gray until you are satisfied that all the displays
look the same for a white image. It is not important to obtain pure
white; it is only important that all the displays look the same.
On each display in the video wall, open the Misc Control menu,
select Test Pattern and choose 50% Gray.
Find the unit that looks the darkest. This may not be the same one
that was the darkest one with a White test pattern. This is the
baseline unit for Gray.
Using the same technique of adjusting a variable display to the
baseline display, match the color and brightness of all cubes,
working with one cube at a time and working outward.
A helpful technique to use when adjusting the colors and gray shades is to
“overshoot” as you adjust to emphasize the effect that the current adjustment
is having to the overall image. Then back off to fine tune. This helps to give
an intuitive feel for the color balance process.
February 03

Page 55
WN-5230A-S VideoWall User’s Guide
It is often helpful to switch between the internal white and gray patterns and
actual video images to fine tune the system. Avoid making major changes
when adjusting to the video images because this can throw off the white or
gray balance. Remember also that the Input Level adjustment has a large
effect on color. If Input Level adjustments have not been made, color balance
for live video will be difficult. However, you may adjust Color Balance before
or after you do the Input Level adjustment. They do not affect each other –
that is, an adjustment in Color Balance does not affect the Input Level
adjustment, and vice versa – but they must both be adjusted properly for the
screens in the cube to match in color, luminance and black level.
Do not adjust Color Balance with Red, Green and Blue test patterns. This is a
method sometimes used with CRT displays, and it will not work with these
Clarity displays. The primary colors have been matched at the factory. If you
get the whites and grays to be the same over a whole wall, all the other
colors will be the same, too.
After you have color balanced all the units, save the settings for each unit. It
does not matter which source-mode combination you save, because color
balance data is saved once for all sources and modes. You should not have
to color balance the displays again until you change a lamp. However, lamps
near the end of their life may begin to change color, so it is a good idea to
check color balance occasionally.
Note: Setting the Gray color balance levels near 004 or 003 will often give
improved performance when the primary program source is composite or
S-video. To try this, reduce the overall brightness of the gray baseline cube to
these levels in the Gry column. Adjust this baseline cube to have the least
amount of color in the 50% gray field. Then balance the other cubes to this
one.

Step 4 – Save, Recall, or Reset the Settings
After all adjustments have been made, Save the settings. There is a separate
Save location for each source in each mode – PC at 800x600, PC at
640x480, RGBS at 31.5 MHz, RGBS at 15.75 MHz, etc. After you have
adjusted the displays for one source, save these settings before going to the
next source and adjusting it.
The Save, Recall, and Reset menus look alike and operate in the same way,
so the explanation for Save will tell you how the Recall and Reset menus
operate. (Resetting does not overwrite the memory where settings are saved.

Clarity’s Big Picture™
Wall Processor Setup Instructions
These are the basic steps to follow to display a single image over an entire wall of
displays. Big Picture can be setup and saved for each video source, so you can
switch between sources while maintaining the specific magnification and position
settings for each source.
1. Build the wall
Install the wall and attach source and power cables as
described in earlier sections.
Use an amplifier/splitter device (distribution amplifier)
from the source or, if you are using loop-thru, use short,
shielded cables to minimize noise and image jitter.
2. Select the Source and
Mode
3. Adjust the image settings
4. Disable wall mode
5. Reset Zoom
6. Center the image
In the menu for each display, select the source that will
use Big Picture. If this is a computer source, use Auto
for Mode selection.
As described in Step 2, Step 3, and Step 4 in earlier
sections, adjust black and white levels for each display;
set phase and frequency; color balance the wall.
Open the Wall Processor menu and make sure that the
Wall mode
checked. Do this for each display.
Set Zoom in the menu to the default width and height of
800x600 or 640x480, depending on the Source and
Mode.
Find the edges of the image using the arrow buttons in
the Position menu to move the image.
For glass screens the mullion (metal lip holding the
edge of the glass) should cover 2 pixels of the image.
Each key press in the Position menu moves the image
one pixel at a time. Move the image so that 2 pixels on
each side of the image are behind their respective
mullions. For acrylic screens, one pixel should hide
behind each edge. When you move the standard size
(not zoomed) image, if you find that more or fewer than
2 pixels (or one pixel) are hidden, then the optical image
size needs to be adjusted. Do not Zoom the image to
accomplish this.

7. Set each display’s address
(See note below for walls
larger than 4x4.)
Assign each display a unique address using the Unit
ID knob. Both the Group and Unit ID numbers are
used
The address of the display in the upper left corner (as
seen from the front) must be zero. The addresses of
the other displays must increase left to right, top
bottom, increasing by one for each display. Therefore,
the display in the lower right corner (as seen from the
front) always has the highest address.
8. Set the Wall Size on each
display
2x2 example $
(Seen from the
front)
3x3 example $
Open the Wall Processor menu. Enter the horizontal
and vertical wall size. Each display’s menu should
show the same horizontal and vertical wall size.
Each display should show a different Current Unit
value. This value represents its location in the wall.

Note: Clarity’s Big Picture handles up to a 6x6 video wall. Because the Unit
knob only has 16 positions, the Group knob must be used for all walls that
have more than 16 displays. A 6x6 wall would be numbered like this (top
number is Group; bottom number is Unit):
00 01 02 03 04 05

Move the menu cursor to the Calc wall pos line and
press the ENTER button. This calculates the position of
the selected display within the image and puts the
display into Wall Mode. Each display will now show only
its segment of the overall image.
Do this with each display in the wall and exit the Wall

If the previous steps were done correctly, the image in
each display should not need to be adjusted by more
than two lines or pixels in any direction.
If an adjustment to the image must be made, use the
Zoom menu to move only the edge that needs
adjustment.

11. Save the settings
If there are other video sources on different input connectors that will
use Big Picture, go through the previous process for each video
source. Then save these settings.
Loop-Thru of Source Video
Loop-thru works in different ways depending on the type of source.
If the source video is PC or MAC, the same signal is output from the
LOOP-THRU connector, which can be connected to the next unit’s PC
input.
If the source is RGB with separate composite sync at 31.5 kHz
(progressive scan), it will come out the LOOP-THRU connector as
RGB with the composite sync on the connector’s H-Sync pin and
separated V-Sync on the V-Sync pin. Feed this to the next unit’s RGBS
connector. It might also work to feed this to the next unit’s PC
connector.
If the source is RGB Sync on Green at 31.5 kHz (progressive), it will
come out the LOOP-THRU connector as RGB-Sync on Green, plus
composite sync on the H-Sync output pin, and separated V-Sync on
the V-Sync pin. Feed this to the next unit’s RGBS connector. It might
also work to feed this to the next unit’s PC connector.
Open the Save Config menu and save the settings for
the current Source and Mode on each display, as
described above in Step 4 – Save, Recall, or Reset the
Settings on page 46.
If the source is RGBS at 15.75 kHz (interlaced), the output from the
LOOP-THRU connector will also be 15.75 kHz. It will not work to loop
this output to the next display’s PC input, because the PC input is
expecting 31.5 kHz. To loop RGBS at 15.75 to the next display, make
an adapter to go from 15-pin to 9-pin using the wiring diagram below.
Standard 15-pin-to-9-pin adapters may also be available from some
computer stores. Connect the first display’s LOOP-THRU output to the
next display’s 9-pin RGBS input. Alternatively, use a 15-pin to 4-BNC
adapter cable. These are also usually available from electronics or
computer stores.
Composite and S-video inputs have their own separate loop-thru
connectors. These are buffered. The inputs are terminated in 75 ohms.
Using video loop-thru slightly degrades signal quality as the signal
goes through each cube. The amount of degradation depends on
cable quality, source video, and the number of loops. If this
degradation becomes a problem, use a signal splitter or distribution
amplifier to directly drive each cube or to at least reduce the number of
loops.

Cleaning and Maintenance
Once the WN-5230A-S is set up and adjusted, periodic maintenance
will consist of cleaning the display and replacing consumable parts such
as the lamp and filter. Use the procedures in this section to remove and
replace WN-5230A-S modules as needed to maintain trouble-free
operation.
Lamp
Before you remove the lamp, switch off the WN-5230A-S with the
remote control, or press the black POWER button on the electronics
module, and allow the lamp cooling cycle to finish (30 seconds). Then
switch off the power at the rear panel AC switch.
CAUTION
The lamp is very close to its cooling fan. This fan does not
stop when the lamp turns off or after the cooling period. It is
always running, unless power is removed from the whole unit.
When you remove the lamp, your fingers may go into the
moving fan. Whether you replace the lamp from the front or
from the rear, remove the power cord or switch off the power
at the power input on the rear panel, before removing the
lamp.
Lamp Replacement, Rear Access
1. Turn off the power
2. Unplug power cord
Switch off the WN-5230A-S using the remote and allow the
cooling cycle to complete (30 seconds) before switching off
the AC power at the rear-panel switch.
Remove the AC power cord from the display.
3. Remove the rear
access cover
4. Remove the lamp
access door

Unfasten the 9 quarter-turn screws on the rear access
cover and remove the cover.
On the right side of the optical engine is the lamp access
door. Pull on the latch to open and remove the door.
Page 73
WN-5230A-S VideoWall User’s Guide
Air Filter
5. Detach the lamp
cable
6. Remove the lamp
7. Install the new
lamp and
reassemble the
display
Using two fingers to unlock the lamp cable connector
clamp, use a third finger to pull the connector away from
the lamp.
The lamp cable will remain connected to the optical engine.
Push the lamp to the left (into the optical engine) while
turning counterclockwise. The lamp will rotate about an
eighth of a turn before it can be pulled to the right and
removed.
Reinsert a UHP 100W lamp in the same orientation. Push
the lamp in (to the left) and rotate the lamp clockwise until it
locks into place.
When attaching the lamp cable, pinch the connector clamp
together while inserting the connector. The connector is
keyed so it will only go on one way.
Replace the lamp access door on the optical engine.
Replace the rear access cover.
Length of time between air filter replacements depends on the
environment in which the WN-5230A-S is operated. Check the air filter
periodically and replace it when it is dirty, but don’t use it for more than
8,000 hours. An excessively dirty air filter can block air flow to the
optical assembly and cause excessive heat buildup inside the WN5230A-S. The air filter is most easily accessed from the rear of the WN5230A-S by first removing the rear access cover.
Air Filter Replacement, Front Access
1. Turn off the power
2. Unplug power cord
3. Remove the screen
4. Open the projector
compartment hood
5. Replace the air filter
Switch off the WN-5230A-S using the remote and allow the
cooling cycle to complete (30 seconds) before switching off
the AC power at the rear-panel switch.
Remove the AC power cord from the display.
Follow the steps outlined for Lamp Replacement to remove
the screen.
There are two spring latches on the projector compartment
hood. Pull these latches towards each other and pull the
hood towards the front of the display to open it.
The air filter is located behind the two cooling fans on the
right. Use a flat blade screwdriver to pry the filter to the left.
When the filter has cleared the bracket, carefully (to avoid
dropping dust) remove it from the display.

4. Replace the air filter
Cleaning the Screen and Mirrors
The best way to clean screens and mirrors is with clean, dry,
compressed air and try to blow off the debris. If this does not work (a
finger print, for instance) use a good quality optical cleaning solution
and lint-free paper wipes or cheesecloth. Note: Apply the liquid
cleaning agent to the tissue first; don’t spray it directly on the mirror or
screen. This will sometimes appear to leave a light residue, but it will
buff off, leaving a streak-free mirror. Because the mirrors are frontsurface mirrors, use care when cleaning them.
Switch off the WN-5230A-S using the remote and allow the
cooling cycle to complete (30 seconds) before switching off
the AC power at the rear-panel switch.
Remove the AC power cord from the display.
Unfasten the 9 quarter-turn screws on the rear access
cover and remove the cover.
The air filter is on the left side of the display. To remove it,
pull it to the right.
Some representative cleaning products are:
• Claire
®
#50 Glass Cleaner—This foam spray product is available
throughout the US and much of the rest of the world. It is sold
under various local names. A janitorial supply company probably
has it under its own name. Ask for their version of Claire
Glass Cleaner. It is also sold under the Sprayway
®
#50 name.
• Glass Wax™ is a thick liquid that works well on glass but not on
acrylic surfaces.
The inside of the screen is harder to clean; usually the problem on the
inside is finger prints. Do not use cleaning products on the inside of the
screen. Instead, use a little isopropyl alcohol on a piece of cheese cloth,
and don’t press hard. Don’t buff it off. Let the alcohol evaporate.
CAUTION
The screen is a laminate of two pieces. If excess liquid runs
down the screen and collects at the bottom, it can wick up
between the two parts. This is nearly impossible to correct.

Troubleshooting
This section provides tips and strategies for resolving problems or issues you
may encounter, either during installation or in normal use of the WN-5230AS. Many problems can be rectified without the need for service by following
the troubleshooting steps below.
If you are unable to resolve the problem by following the suggestions listed
under the Failure Symptoms column, you will need to contact your service
provider.
Power and Start-Up Problems
When AC power is applied to the unit by turning on the main AC power
switch, the display enters a 30 second standby-delay period to prevent
ignition of a hot lamp. During this time, the display will not accept commands
from the remote control.
The unit enters the Standby mode when the 30 second standby-delay
sequence is complete. The display is ready to accept an “ON” command
when the Standby LED comes on.
This is the sequence of events that must occur for a WN-5230A-S to powerup and display an image.

On Off Off Display is in Standby mode
Table 2
Note 1 If the STBY LED is flashing and the Lamp LED is off, one of two conditions
exist. Either the display was just shut down normally with the On/Off button
or the unit has shut itself down and the likely cause is that the interlock
circuit is open. The interlock circuit consists of switches behind the front
screen and rear access panel. These prevent accidental exposure to
hazardous voltages when the display is turned on. Verify that the screen
and rear access cover are in place. If the problem persists, contact your
service provider.
Note 2 If the STBY LED is off, the Lamp LED is on, the Fan LED is on and the
lamp is not lit, the electronics module is operating and the likely problem is
with the lamp or it’s power system. If replacing the lamp and restarting the
WN-5230A-S does not resolve the problem, contact your service provider.

REMOTE
The green STBY light emitting diode (LED) is on steady
when unit is in Standby mode and main electrical power is
switched on. This LED blinks for 30 seconds when the
main power is initially switched on or when the lamp is
switched off to enter Standby mode. When it is blinking,
the power on button for the lamp is inhibited.
This LED will blink at a faster rate when the lamp is being
ignited.
This is a green LED that is on when the cooling fan is
running. It remains on for the 30 second cool-down cycle
after the lamp is switched off. It is on during the initial
30-second period after AC power is applied.
This is also a green LED. It is on when the display
electronics has turned on the projection lamp.
(Not functional in the WN-5230A-S)
Indicates activity of the IR sensor. Stray Infrared radiation
causes a faint glow and flicker. A signal from the Remote
Control causes a 1/10th second flash.

On = valid source detected on the selected input. If this is
off, either the wrong source is selected, or the source has
no signal in it.
This LED glows whenever data activity is detected at the
RS-232 connector. It does not matter whether the packet
was addressed to this unit on not, or even whether this is a
command formatted for Clarity display use. It tells you
there is a good connection to the controlling computer.
The brightness of the LED is proportional to the density of
the incoming data.
This LED glows very briefly whenever a valid packet of
data is detected at the RS-232 connector and the packet is
meant for this unit. It may be a global command, or a
command addressed specifically to this unit. This display
unit will try to execute this command. It will return an
acknowledgement (ACK) only if the command was
addressed to this unit exclusively.

Control Description
MONITOR ID
POWER
Power On/Off
16-position rotary switches select a unique Monitor ID number for
each unit in a video wall configuration. The two switches have a
total number of 256 individual Monitor ID settings.
GROUP - ID numbers are 0 – 9 and A – F for a total of 16
different settings. Each number is equal to that
number times 16. A setting of 3 is equal to 48.
UNIT - ID numbers are 0 – 9 and A – F for a total of 16
different settings. Each number is equal to that
number times one. A setting of 3 equals 3, a setting of
B equals 11.
The Monitor ID number is the combination of the Group ID plus
the Unit ID. A Group ID number of 2 and a Unit ID number of 5
equals a Monitor ID of 37.
This setting also delays the time between an “on” command to
the VideoWall and the ignition of the lamp. The delay is
approximately 2 seconds times the Monitor Unit ID number.
Power On/STBY push-button switch. Controls power to the lamp
and fans by toggling unit between ON and STBY
modes.
Rocker switch near the A/C power input connector. Main AC
power switch.
Remote-Control
Use the remote control or RS-232 input for all setup and
control functions. The remote must be pointed directly at
the display for the VideoWall to “see” the remote’s
commands. The most reliable position for remote control
of the display is on an axis perpendicular to the front of
the screen.
The farther away that the remote control is from the
display, the weaker the signal will be when it reaches the
screen. The weaker the signal, the less reliable the control of the display will
be. The remote is powered by two 1.5 volt AAA batteries.
Remote Control Functions
Some on-screen sub-menus can be accessed directly by pressing the
specific menu item’s associated button on the remote control.
