Introduction
The WN- 5220-S VideoWall is a mult i- frequency, multi-source display capable
of displaying a wide range of video sources. The clear, bright image is a
product of careful engineering and optical innovation. Setup is easy because of
light weight and simple mechanical connections. And it is fast because there
are only a few adjustments necessary to configure the image.
Product Introduction
The optional Ultra-Thin Mullion screen gives the display additional flexibility in
meeting the most demanding image quality applications. By eliminating t he
front-surf ace frame, this screen nearly eliminates the visible seam between the
displays. (Mullion: the metal edge around the screen.)
Clarity’s Big Picture™ option is a built-in data/videowall processor. Without the
need for an external processor, Big Pict ur e can scale t he source video to
accommodate any display wall size up to four high and four wide.
Features
Clarity’s products are designed and developed by experts in LCD projection
technology and offer sig nificant advantages over conventional cathode ray
tube (CRT) based systems including:
optical resolution of 800x600 pixels
•
ability to scale lower resolution sources up to 800x600
•
supports a wide variety of computer and video formats
•

Make sure the power cord is compatible with the nominal power
source used with the WN-5220-S display.
Power Consumption
Power consumption of the WN-5220-S is 920 Watts, or approximately
8 Amps current draw at 115 VAC (4 Amps at 230 VAC). The
WN-5220-S can be configured to operate on either 90-130 VAC or
180-260 VAC nominal power sources at 50/60 Hz.
Voltage Range
The operating voltage rang e of the W N- 5220- S is set via a switch on
the power supply near the AC power plug and on/off switch.
Operation of the display at the incorr ect voltage level can cause
damage to the unit which is not covered by the warranty.
!"Select the setting labeled 115V if your power source is
between 100 and 120 Volts AC.
!"Select the setting labeled 230V if your power source is
between 200 and 240 Volts AC.

Page 19
WN-5220-S VideoWall User’s Guide
On a typical 20A, 115V circuit, no more than t wo WN-5220-S displays
may be installed. This allows an extra current marg in. If any circuit
used to power one or more W N- 5220- S displays is not a dedicated
circuit, the additional electrical load placed on the cir cuit by other
equipment must be considered.
WARNING
Displays that are intended for 240V configuration must have a
properly rated power supply cord and attachment plug supplied
by the installer.
WARNING
If extension cords are used for power, use only 3-prong
grounded cords sized to handle system power requirements.
Using the wrong-size extension cord can cause a fire-safety
hazard and can reduce the voltage available to the
WN-5220-S. If the extension cord is warm to the touch it is t oo
small and should be immediately removed from operation.
Temperature and Humidity
The WN- 5220- S is designed to operate over an ambient temperatur e
range of 0° to 35° C (32° to 95° F) and a humidity of 20 to 80 % R.H.
non-condensing.
Some types of environmental lighting , such as incandescent, or high
intensity discharge lamps such as metal halide or mer cur y vapor
lamps, create high temperatur es and t his can cause excessive
heating of the WN-5220-S. Displays should be positioned far enough
away from high-temperature lights to prevent heat buildup.
Nearby heat sources can cause high operating temper at ur es in the
WN-5220-S display. Minimize the display’s exposure to heating ducts,
radiators, or other external heat sources.
Flooring
A single WN- 5220- S display unit weighs appr oximat ely 120 lbs (55
kg). Befor e inst alling the WN- 5220- 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- 5220-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 installat ion. Never st ack
more than four (4) WN-5220-S displays vertically on a tempor ar y
floor.

Page 20
Clarity Visual Systems
Clearance
Normal maintenance, such as lamp module and air filter replacement,
can be performed from the front or rear of the WN-5220-S. Maintain
sufficient clearance to allow easy access from t he front. A minimum of
4 feet is recommended. For full maintenance from the r ear , the
minimum recommended clearance is 3 feet .
To allow proper cooling, the minimum required clearance to the rear
of the display should be 6 inches. The minimum required clearance to
the top at the front of the unit is 6 inches. See Environmental
Specifications on page 97 for cooling requirements.
If installed in a video wall configuration, a m inim um of 12 inches to
the ceiling from the t op of the highest display is needed if the unit s
are installed from the front.
Cooling
Regardless of clearances and the gener al am bient temperature, the
most important fact or t hat affects reliable operat ion is t he temperature
and quantity of air coming int o the display. The intake air temperature
at the air filter must not exceed 95° F (35° C). If there is any doubt
about this temperature in an installat ion, r un t he displays for several
hours before taking t em per at ure measurements. Prevent problems by
replacing dirty air filters and keeping the air path clear.

Figure 1 Connecting display units
To setup the WN-5220-S display in a video wall configuration, follow
these steps:
1. Grasp the screen on each side
at the bottom
2. Slip fingers between the screen
frame
3. Using both hands…
The “screen” you are removing is 2 or 3 inches thick.
Pull out at the bottom first, to separate the latchhooks from the latches. It comes out with a “pop.”
The screen should now be loose at the bottom, but
still attached at the top.
Slip fingers between the screen frame and the
display chassis, as close to the top latches as
possible and pull the top of the screen from the
latches.
Carefully remove the screen and set it aside.

4. Assemble the lower row first.
5. Stack the next higher row.
6. Insert a supplied fastener.
Line up the legs for the bottom row as straight as
possible.
Insert a ¼” X 2 ½” bolt through the holes as shown
in Figure 1. Tighten a nut securely on this bolt.
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
putting the lower row of displays on it.
Before going to the next higher rows, see that the
bottom row is straight. From one end of the line, look
along the front of the displays. The line should be
straight and flat. Level is not as important as straight
and flat.
Slide the legs of each display into the mating sockets
of the display in the first (lower) row. Check it for
“straight and flat.”
Insert a bolt through the hole in side wall of the lower
unit into each leg of the unit above.

Installing a video wall with Ultra-Thin
Mullion Screens is a little more complex
than installing the wall with standard
mullion screens. Mechanical alignment is
more 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 most ly dependent on
how tightly the displays are fitted to each
other.

front surfaces (t he scr een faces) are flat with each other. Then do t he
rows above.

black tape to prevent light leak s.
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.
.
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 down the row. 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 get in right.
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
securing it to the floor and putting the lower row of
displays on it. 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.
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
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.)
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 pointed Alignment Bolt, and an Alignment Hole.
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
standard is 3/32
nd
of an inch, measured to the
base of the hex nut, or three full revolutions of the
bolt from when it is completely down against the
frame.
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
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,
nd
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.

5. Align the adapter plates on the
units above the Base Unit,
working upward.

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 squarecornered 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 upper
uide pin should now fit the bottom Alignment

6. Hang the screens on the
bottom row and adjust them in
or out so their front surfaces
are flat with each other.
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.

7. Put retaining screws in the top
row and cover holes and seams
with black tape to prevent light
leaks.
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
of displays with black cloth tape. “Gaffer” tape
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.

Cables
Video connections from the signal source t o the WN-5220-S depend
on the type of signal supplied by the source. The com pat ible video
inputs are; PC 800x600 (SVGA), PC 640x480 (VGA), MAC 800X600
or 640X480, and 31.5 kHz (progr essive scan) RG BS Video. The VIM300 option recognizes 15.75 kHz (interlaced) RGBS video, composit e
video, and S-Video for NTSC, PAL and SECAM. These will be
processed and displayed.
The Loop-thru video output uses a standard 15-pin VGA t ype
connector for output to an external com puter monitor or another
display. The format of t he Loop- t hru video is same as the source
video. VGA and MAC will have RGB with separate H-Sync 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 loopthru RGBS-Sync on Green. Displays with the VIM-300 option also
have a Composite Video and S-Video loop-thru connectors.
The video cables used should be high quality and shielded to insure
the best image quality when displayed.
Using poor quality cables can lead to picture noi se, jitter and
crosstalk.
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 transm ission
and control.

You will hear a ‘beep,” and the sound of the internal fans.
The lamp will come on, but will require approximately 5
minutes to fully warm up. There is a built-in delay from
when you press the remote’s ON button to when the lamp
lights. The extent of the delay depends on the Monitor ID
Unit setting. 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 C equals 12.
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.
The delay the time between an “on” command to the
display and the ignition of the lamp is approximately 2
seconds times the Monitor Unit ID number.
Observe the LED on the rear of each unit. When proper
power is on, the STBY LED is off, and the fan and lamp
LEDs are on. A faint glow from the lamp exhaust vent in
the rear of the unit indicates the lamp is on.

About
Color balancing is essentially balancing the brightness and color of all
the lamps in the video wall, so you do not need to color balance the
displays for each source. The color balance inf ormation is saved in
memory in only one location, not for each source.
The goal of color balancing t he displays is to match the luminance
and white color of all the displays in video wall, and then match the
intermediate gray shades. Therefore, color balancing is accomplished
with all displays on in the finished video wall. (If you have only one
unit, color balancing is not very important. )
Select an edge of the image that needs to be expanded or
compressed (Left, Right, Up or Down). It is easiest to see
the effect of Zoom when the image is a some form of
geometry pattern, one that exactly defines the edges of the
image.
Selecting the Lock feature causes the image to scale the
same amount in the opposite direction. If you scale the
Right, the Left will scale by the same amount. Similarly, Up
and Down
The Default feature scales the image back to 800x600 or
640x480 pixels, depending on the source.
Note: Resetting the Scale to default settings will also clear
any Position changes that have been made.

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 lum inance. I n addition, similar
control for the RED, G REEN, and BLUE set tings is provided to adjust
the balance of the gray shades without affecting the white balance.
For white balancing
selections have a number associated with them between 0 and 31.
Zero is the darkest and 031 the brig htest. The ALL selection allows all
of the balance settings to be adj ust ed sim ultaneously. The up/down
arrow keys moves the cursor from All t o Red, Green, Blue in the
White colum n, then All, Red, Green, and Blue in the Gr ay column,
then back to All in the White column again. The left/right arrow keys
increment and decrement the brightness number.

The darkest display is already as bright as it will ever be. This
display will serve as a baseline to which the other displays
will be adjusted, since it cannot be adjusted to be brighter.
Note: The baseline display does not have to be the middle
one. It should be the darkest one, wherever it is in the wall.
Beginning with the display next to the baseline display, adjust
the ALL settings on the white levels to approximately match
the luminance (brightness) of the baseline unit.
Adjust the relative 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 appears to need to be increased, but that color is
already up as high as it can go, then the other two colors can
be reduced. For instance, if you need the white to be have
more red, but red is already at 031, reduce the green and
blue. This will make the display look more red.

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.
Decrease the overall luminance

A helpful technique to use when adjusting the color s and gray shades is to
“overshoot” as you adjust to emphasize the eff ect that the current adjustment
is having to the overall image, and then to back off to f ine t une. This helps to
give an intuitive feel for the pr ocess.
It is often helpful t o switch between the internal white and gray patterns and
actual video images to fine tune the system. Avoid mak ing 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. I f Input Level adjustments have not been made, color balance
for live video will be difficult. However, you may adjust Color Balance
or after
you do the Input Level adjustment. They do not affect each other –
before
that is, an adjustment in Color Balance does not affect the Input Level
adjustment, and vice versa – but they must both be adjusted pr oper ly f or the
screens in the cube to match in color balance, 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.
After you have color balanced all the units, save the setting s 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
41
Page 50

to color balance the displays again until you change a lamp. However, lamps
near the end of their lif e m ay beg in t o change color, so it is a good idea to
check color balance occasionally.

Step 4 – Save, Recall, or Reset the Settings
After all adjustments have been made, Save the set t ings. 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. (Remember,
you only have to do the color balancing once.)
The Save, Recall, and Reset menus look alike and oper ate in the
same way, so the explanation for Save will tell you how the Recall
and Reset menus operate. (Resetting does
where settings are saved. See Figure 4 later in this section.)

This 2x7 connector is next to the power connector, which comes from
the power supply. (Clarity’s Big Picture cannot be field installed to
Electronics Modules that do not have a 2x7 connector.)
The Option Key consists of and integ r at ed Printed Circuit Board
Assembly and Cable Harness. Included as part of the Pr inted Circuit
Board Assembly are 2 adhesive backed nylon PC Board mounts. To
install it, follow these steps.
1. Turn off the power
2. Plug in the
connector
3. Mount the circuit
board
4. Turn on power
If the display is on, turn it off with the remote control
(or by pressing the button on the rear panel). Wait
for the fans to stop (3 minutes). Turn off the power
with the switch at the power supply input and
remove the power cord.
Plug the connector of the Big Picture Option Key
into the 2x7 connector on the Electronics Module.
Remove the protective backing from the PCB
mounts. Apply the mounts and board assembly in a
vertical orientation to the back of the small mirror
mount.
Connect the power cord and start the display as
usual. Note: The Big Picture Option Key can be
installed without turning off the power. However, the
Electronics Module must be re-started from a nopower state to recognize the presence of the key.

Cleaning and Maintenance
Once the W N-5220-S is set up and adjusted, periodic maintenance will
consist of cleaning the display and replacing consumable par t s such as
the lamp and filter. Use the pr ocedur es in this section to remove and
replace WN-5220- S m odules as needed to maintain trouble-free
operation.
Lamp
Before you remove the lamp, switch off the WN- 5220- S with the r em ote
control, or press the black POWER button on the electronics module,
and allow the lamp cooling cycle to finish (3 minutes). T hen switch off
the power at the rear panel AC switch.

Air Filter Replacement, Front or Rear Access
Length of time between air f ilt er replacements depends on the
environment in which the display is operated. Air filter cleanliness
should be periodically checked and the air filter r eplaced when dirty, at
a minimum of every 3,000 hours of operation. An excessively dirty air
filter can block air flow to the optical assembly and cause excessive
heat buildup inside the display, possibly reducing lamp life. The air filter
is most easily accessed from the rear of the display by first removing
the lamp access cover.

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 solut ion
and lint-free paper wipes or cheesecloth.
cleaning agent to the tissue first; don’t spray it directly on the mirror or
screen. This will sometimes appear to leave a light r esidue, but it will
buff off, leaving a streak-free mirror. Because the mirrors are frontsurface mirrors, use care when cleaning them .
Some representative cleaning products are:
Install a new filter with the arrow on the top edge up and
pointed toward the optical assembly (front of display).
Switch on the unit and check for proper airflow by holding
a piece of paper near the airflow exhaust at the rear of the

Troubleshooting
This section provides tips and strategies for resolving problems or issues you
might encounter either during installation or in normal use of the display.
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 tur ning on the main AC power
switch, the unit enters a 3-minute standby-delay sequence. During this time,
the STBY LED on the rear panel flashes and the Lam p and Fan LEDs are
off. Also during this time, the unit does not respond to remote or manual
controls and alerts you that it is locked by giving 3 short beeps when you
press a button on the remote control.
The unit enters the standby mode when the 3-minute standby delay is
complete. This is shown when the STBY lamp comes steadily on. At this t im e
the unit is ready to accept an “ON” command.
This is the sequence of events that m ust occur for a W N- 5220- S to light the
lamp and display an image.

Much of the preliminary diagnostics can be done by observing the 3 LEDs on the
rear connector panel. Table 2 shows the LED combinations for the most likely
failure modes if the WN-5220-S is not oper at ing correctly.

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 on the front screen and rear
lamp access panel. These prevent accidental exposure to the lamp when it is
turned on. Verify that the screen and rear lamp access doors 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-5220-S
does not resolve the problem, contact your service provider.

selected input, the unit will selected the correct mode for the input.
If you can see any menu, even if it is upside down or left-right reversed,
it means the Electronics Module is talking to the LCD correctly.
With the remote control, press Curtain. If there is an X in Curtain On,
press Enter. Curtain On prevents the source signal from getting to the
screen.
Is the Source black? If the source is black, as it might be if the source
is a computer and the computer is in a sleep mode, the image will be
black. If the source is video, are you in the tape leader or trailer that is
black?
Has the lamp failed? If the FAN and LAMP LEDs are on, the unit
believes that the lamp is on. Look at the rear panel, if possible. When
the lamp is lit, you should be able to see some light coming out of fan
exhaust opening.
Is the Black Test Pattern being used? In Misc Control, choose Test
Patterns, then choose Off.
Is the source all white?
Press Menu on the remote control. If you see a menu, then the
Electronics Module is talking to the LCD. If you can’t bring up any

Get closer with the remote control.
Aim at a different point on the screen, and change the angle.
Remove the screen and look at the Electronics Module. The IR sensor
is on top, near the 4-pin connector, facing up. Is it covered?
Are the AAA batteries in the remote control good?
This is probably an interlock problem. Normally, after the 3-minute
delay during which the STBY LED flashes, the STBY LED is on without
flashing, and the FAN and LAMP LEDs are off. If you press On at this
time, and the STBY LED starts flashing again, it is almost always
caused by an open interlock.
Check the screen. Is it pressed into place in all four corners? (UltraThin Mullion screens do
Is the rear panel in place and secure?
This is normal. After the 3-minute delay, there is an additional delay
time determined by the Unit ID knob setting. When you press ON, the
lamp waits 2 seconds times the Unit knob setting. If the knob is set to
9, the delay is 18 seconds. If the knob is on F, the delay is 2x15=30
seconds.
If the source is 800 x 600, and you manually switch to the 640 x 480

separate from the BNC RGBS input. Video can be cabled to
both the 9-pin D-Sub and the BNC connectors and selected
in the Source menu. With the VIM-300 option, this port will
also accept component 15.75 kHz video. If you use 15.75
kHz RGB video, see Exception above under Loop-Thru.
Sync can be composite sync on the S pin or sync-on-green.
This is also the input to use when coming from the LoopThru connector of another display unit.

RS-232 Control
Transmission Speed 19200 BAUD
Transmission Data Data Length: 8, Stop Bit: 1, Parity Bit: None
No standard hardware or software pacing is used such as DTR/ RTS
or XON/XOFF. Commands should be paced using the ACK, NAK,
UNK, or ERR responses from the display.
Standard RS-232 levels, +/- 12V, are used. Some lapt op PC’s use
ground and +5V and are not always successful in communicating with
the display.
The display’s RS-232 port is always active except during the boot
process which is the first 10 seconds after power is applied to the
display electronics.
In single address mode (not when global commands are being used)
the host machine must wait for an ACK, NAK, UNK or ERR response
from the display before sending t he next com m and. When global
commands are sent, the displays will not return a response, so a
delay of ½ second should be maintained between commands to avoid
possible errors.
The protocol for communicat ion t o the display consists of a 7 byte
command line as described below.

IDT
- Monitor ID bytes are used to identify which display will receive
the RS-232 command. This is a 2 byte address that is set by the
Group and Unit Monitor ID knobs on the display’s connector panel.
Each knob has 16 possible settings with the Group setting t he high
byte and the Unit setting the low byte. The address consists of the

Clarity Visual Systems
ASCII Alphanumeric characters (0-9, A-F for the Group setting and
0-9, A-F for the Unit set ting) providing the means to control up to 256
combinations (00 to FF).
Multiple units can be controlled simultaneously by using the ASCII
character for the asterisk (*) in place of either or bot h of the IDT
monitor ID bytes. The (*) is a wild card character and pr ovides a
means to control multiple units simultaneously. There are four types
of addressing that are support ed.
1. Single address mode
01, 02, A2, AA, FF are valid examples. Only the single
display that matches this address attempts t o execute t his
command. An acknowledgement is sent in this mode.
Note
: Do not set several displays to the same Unit and
Group address. If two displays have the same Group and
Unit ID, and a Single Address Mode command is sent to
that address, both units will send an acknowledgement at
the same time, causing some conf usion in t he data on the
RS-232 line.
