Site Requirements
Power
Make sure the power cord is compatible with the nominal power
source used with the WN-5220-V VideoWall.
Power Consumption
Power consumption of the WN-5220-V VideoWall is 920 Watts, or
approximately 8 Amps current draw at 115 VAC (4 Amps at 230
VAC). The WN-5220-V VideoWall 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 range of the WN-5220-V VideoWall is set via a
switch on the power supply near the AC power plug and on/off switch.
Operation of the VideoWall at the incorrect 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 90 and 130 Volts AC.
!"Select the setting labeled 230V if your power source is
between 180 and 260 Volts AC.
If the input voltage drops below approximately 85V (170V if the
WN-5220-V is set to the 230V setting) the display will automatically
shut down to protect itself.
On a typical 20A, 115V circuit, no more than two WN-5220-V displays
may be installed. This allows an extra current margin. If any circuit
used to power one or more WN-5220-V VideoWalls is not a dedicated
circuit, the additional electrical load placed on the circuit 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-V VideoWall. If the
extension cord is warm to the touch it is too small and should be
immediately removed from operation.

WN-5220-V VideoWall User’s Guide
Temperature and Humidity
The WN-5220-V VideoWall is designed to operate over an ambient
temperature 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 mercury vapor
lamps, create high temperatures and this can cause excessive
heating of the WN-5220-V VideoWall. VideoWalls should be
positioned far enough away from high-temperature lights to prevent
heat buildup.
Nearby heat sources can cause high operating temperatures in the
WN-5220-V VideoWall. Minimize the VideoWall’s exposure to heating
ducts, radiators, or other external heat sources.
Flooring
A single WN-5220-V VideoWall unit weighs approximately 120 lbs (55
kg). Before installing the WN-5220-V VideoWall, 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 VideoWalls and other equipment used in the
installation. Take special care when installing a WN-5220-V
VideoWall 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. Never stack more than four (4) WN-5220-V
VideoWalls vertically on a temporary floor.
Clearance
Normal maintenance, such as lamp module and air filter replacement,
can be performed from the front or rear of the WN-5220-V VideoWall.
Maintain sufficient clearance to allow easy access from the front. A
minimum of 4 feet is recommended. For full maintenance from the
rear, the minimum recommended clearance is 3 feet.
To allow proper cooling, the minimum required clearance to the rear
of the VideoWall is 6 inches. The minimum required clearance to the
top at the front of the unit is 6 inches. See Environmental
Specifications on page 67 for cooling requirements.
If installed in a video wall configuration, a minimum of 12 inches to
the ceiling from the top of the highest VideoWall is needed if the units
are installed from the front.

Mechanical Setup
Install the WN-5220-V VideoWall in the desired position and connect
the power and signal cables. See the following section for an
explanation of the cabling configuration.
To setup the WN-5220-V VideoWall in a video wall configuration,
follow these steps:
1. Remove the screen
from each unit to be
used in the video wall.
2. Build the video wall.
3. Assemble the lower row
first.
4. Stack the next higher

Cables
Video connections from the signal source to the WN-5220-V
VideoWall depend on the type of signal supplied by the source. The
compatible video inputs are; 640x480 VGA, Mac II and 31.5 kHz
RGBS Video. With the optional VIM line-Doubler/Scaler card 15.75
kHz RGBS Video is recognized and with the optional VIM decoder
card Composite Video and S-Video will be processed and displayed.
into each leg of the unit above.
Tighten a nut on this bolt to lock the units together. See
Figure 1 above.
Lock each VideoWall to the adjacent VideoWalls after the
row above it (if any) has been installed.
Use the rear-tapped holes in 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.
Check that all VideoWalls in the video wall are locked
together.
Reinstall each VideoWall’s screen.
The Loop-thru video output uses a standard 15 pin VGA type
connector for output to an external computer monitor or another
VideoWall. The format of the Loop-thru video is same as the source
video. VGA and MAC II will have RGB with separate H-Sync and VSync. 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. VideoWall displays with the optional
VIM-200 option using a Composite Video or S-Video source will not
output a loop-thru signal for those two sources.
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 VideoWall via the RS-232 In connection, and
is supplied to an adjacent VideoWall (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.

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
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
VideoWall 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
LED’s are on. A faint glow from the lamp exhaust vent in
the rear of the unit indicates the lamp is on.

To adjust the colors, first match the luminance (brightness) and the
color of white. Do this for each one of the displays. Then match the
intermediate shades of gray.
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. In addition, similar
control for the RED, GREEN, and BLUE settings are provided to
adjust the balance of the gray shades without affecting the white

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, and then to back off
to fine tune. This helps to give an intuitive feel for the process.
It is often helpful to iterate between the full white and gray fields and
actual video images to fine tune the system. Avoid making major
changes when adjusting to video images, as this can throw off the
white or gray balance. Remember also that the input level adjustment
has a large effect on color, and the input level adjustment procedure
be followed for each source prior to color balancing.

Cleaning and Maintenance
Once the VideoWall is set up and adjusted, operation consists of
selecting and displaying material, turning on and off the curtain, and
switching the unit on and off. All other display effects are controlled by
the input device.
Use the procedures in this section to remove and replace WN-5220-V
modules as needed to maintain trouble-free operation.
Screen
The WN-5220-V VideoWall contains electrical interlocks that prevent
operation when the front screen is removed. Never operate the
VideoWall with any access panels or the front screen removed from
the unit, except when required for servicing. Operating the VideoWall
with access panels or the front screen removed can expose service or
operating personnel to ultraviolet burns and high electrical voltages.
Always wear ultraviolet-blocking eyewear with side guards when
servicing the VideoWall.
Removing the screen provides service access to other replaceable
modules from the front of the VideoWall.
CAUTION
by hand without damaging the screen. Where screen edges are
adjacent to each other in a wall configuration, removal of the screen
without
screen latch. In these applications use an SRT-100 screen removal
tool to minimize the chance of damaging the screen.

Lamp
The lamp must be allowed to cool prior to removal. Wait at least 3
minutes after turning off the VideoWall to remove the lamp.
Before attempting to remove the lamp module, switch off the
WN-5220-V with the remote and allow the lamp cooling cycle to
complete (3 – 4 minutes) before switching off power at the rear-panel
power switch. The lamp module may be removed and replaced from the
front by first removing the screen (see Screen on page 45), or from the
rear by removing the lamp service access cover.
Before servicing the VideoWall, always switch the AC
WARNING
power off at the rear-panel power switch and remove the power cord.
When the WN-5220-V VideoWall is connected to the electrical mains,
some circuits still contain line voltage, even when power is switched
off.
CAUTION
Do not touch the lamp or reflector. Oils from the skin will
cause these surfaces to become etched when the lamp is operated,
dramatically shortening the life of the lamp.

rear-panel switch.
Remove the AC power cord from the WN-5220-V.
To gain access to the lamp from the front of the VideoWall, remove the
screen first.
To gain access to the lamp from the rear of the VideoWall, unfasten the
8 quarter-turn screws on the lamp access cover and remove the cover.
The lamp connector is next to the reflector fan. Unplug the connector by
pulling up on it.
Unhook the two latches holding the lamp module to the optical
assembly.
Lifting up on the handle, tilt the lamp module away from the latches until
it can be pulled free of the optical assembly.
Carefully remove from the VideoWall by lifting the lamp module straight
up to clear the fans, and then withdrawing.
Replacement is the reverse of the above procedure. After installing the
lamp module, ensure that the high-voltage connector is in place and that
the latches are securely latched before replacing the screen or the lamp
service access cover.
8. Reset the Lamp Hours
Air Filter
Length of time between air filter replacements depends on the
environment in which the VideoWall is operated. Air filter cleanliness
should be periodically checked and the air filter replaced 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 VideoWall. The air filter is most easily accessed
from the rear of the VideoWall by first removing the lamp access cover.

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
unit.
Cleaning the Screen
The screen’s lenticular pattern is sensitive to smudges and scratches.
To clean smudges from the screen, use a soft cloth and a nonabrasive, non-hydrocarbon cleaner. Wipe the screen from top to
bottom, in the same direction that the lenticular runs.
Cleaning the Mirrors
The WN-5220-V’s optical mirrors can become dusty in normal
operation, particularly if the operating environment is dusty. When the
WN-5220-V is serviced, these mirrors may also accumulate accidental
smudges and fingerprints. Dust and smudges on the mirrors can
seriously degrade the WN-5220-V’s performance, so these should be
removed as soon as possible.
Because the mirrors are front surface mirrors and the lens is coated,
use care when attempting to clean them. They are easily scratched if
improperly cleaned. Use an inert dry dusting gas or dry, filtered
compressed air to remove dust from the mirrors. To remove smudges,
use an optical quality liquid cleaner and a disposable commercial lens
tissue. If the liquid is not a spray, apply it to the tissue first.

Troubleshooting
This section provides tips and strategies for resolving problems or issues you
might encounter either during installation or in normal use of the VideoWall.
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 unit enters a 3-minute standby-delay sequence. During this time,
the STBY lamp on the rear panel flashes and the Lamp and Fan lamps 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
time the unit is ready to accept an “ON” command.
This is the sequence of events that must occur for a WN-5220-V to light the
lamp and display an image.

Much of the preliminary diagnostics can be done by observing the 3 LED’s on
the rear connector panel. Table 2 shows the LED combinations for the most
likely failure modes if the WN-5220-V is not operating correctly.

Note 3
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.
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-V
does not resolve the problem, contact your service provider.
If the STBY LED is off and Lamp LED is off and the Fan LED is on, the
electronics module is probably at fault. Contact your service provider.

No hardware or software pacing is used such as DTR/RTS or
XON/XOFF.
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 the next command. 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 communication to the display consists of a 7 byte
command line as described below.
STX

IDT
(2 byte)
CMD
(3 byte)
ETX

Where;
ASCII STX

- Start of transmission character, = 02h
Ctrl- B
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 the high
byte and the Unit setting the low byte. The address consists of the
ASCII Alphanumeric characters (0-9, A-F for the Group setting and
0-9, A-F for the Unit setting) 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 both of the IDT
monitor ID bytes. The (*) is a wild card character and provides a
means to control multiple units simultaneously. There are four types
of addressing that are supported.
1. Single address mode
A2, AA, FF are valid examples. Only the single display that
matches this address responds to it. An acknowledgment is sent
in this mode. Do not set multiple displays to the same address.
2. Group address mode
while the unit part of the address is not: 1*, 9*, A*, F* are valid
– the entire address is specified: 00, 01, 02,
– the group part of the address is specified,

examples. All displays that match the group respond to this
addressing mode. No acknowledgment is sent in this mode. All
displays must be set to a unique address.
3. Unit address mode
while the group part of the address is set as global: *2, *9, *F are
valid examples. All displays that match the unit respond to this
addressing mode. No acknowledgment is sent in this mode. All
displays must be set to a unique address.
4. Broadcast mode
