1.3Safety for You and Bay Cat X
This list of safety warning and caution notes isn’t very long. Reading it could save you from getting an electric
shock.
This display was designed with safety in mind. However, if you don’t heed the safety warning and cautions, you
could get hurt. The safety warning are on stickers in various
places in and on the display. They are reproduced on these
pages so you can see them all at once.
There are some other times you should know relating to
safety:
WARNING
Wall mount s must be secure.
If the displays are hung on a wall, the wall must be
strong enough to hold them. Each display unit weighs
about 73 lbs. (33 kg). Simply mounting it to wallboard or
wall paneling won’t be adequate or safe. The mounting
method must be capable of holding 5 times this weight, 275
lbs. (125 kg) for each display unit.
CAUTION
The screen could be damaged by heavy pressure.
lamp). Follow local ordinances and regulations for disposal.
Bay Cat X screens are protected with a cover glass to
protect the LCD.
Some Bay Cat Xs are shipped, at customer request,
without this protective glass. In these, the LCD is not protected. Slight pressure on the LCD will cause distortion of
the image. Heavier pressure will cause permanent damage.
Bay Cat Xs of this type should be mounted where viewers
cannot touch the screen.
WARNING
The backlight contains mercury.
The backlight is 24 mercury vapor fluorescent lamps.
These cold cathode fluorescent lamps behind the LCD
panel contain a small amount of mercury (112 mg in each

2.1Installing the DVI Board or SDI Board
Clarity Visual Systems ships the DVI or SDI board separately from the Bay Cat X to some customers and for field
upgrades.
✎
The DVI Board is the field-installed video board for
the Video Model of Bay Cat X. The SDI Board is
the field-installed video board for the Broadcast
Model of Bay Cat X.
1. If you powered up the unit to confirm proper working
order upon receipt, turn off AC power to the Bay Cat X
and remove the power cord.
2. Place the unit face down on a flat surface on something
soft and non-scratching. If your unit does not have a
protective face glass panel, be EXTREMELY careful as
the LCD material can be scratched.
3. Confirm that your DVI Board package contains four (4)
mounting screws (SDI Board package contains six[6]
srcews), a replacement DVI or SDI cover panel, and a
disposable grounding wrist strap.
4. On the back of the Bay Cat X, remove the blank cover
panel.
b) Remove the blank panel by pushing down slightly
on the inserted end of the panel as you pull it out.
As you remove the panel,
push down slightly on this
end of the panel as you pull
it towards you
a) Unscrew the two screws holding the blank panel in
place. Save the screws for the replacement panel you
will install later.
6
c) Recycle the blank panel with other aluminum scrap
metal.
5. Attach the grounding wrist strap to bare metal on the
chassis. Using standard ESD procedures, remove the
DVI or SDI board from the anti-static bag. (The DVI
board is shown in the pictures below.)
Use a grounding wrist
strap (not shown) or
other personal ESD
devices to prevent
damage to the board
6. Carefully slide the right side of the board into the slot
on the right side of the opening.
7. Align the connector on the board with the connector in
the opening.
Gently push the board into the connector. The board is
fully seated when the four screw holes (six for the SDI
board) are aligned.
8. Screw down the four corners of the DVI board (six
screws for the SDI board) with the supplied mounting
screws.
7
9. Slide the DVI or SDI replacement cover panel into
place. Press down gently on the insertion end of the
panel to help the tabs insert in the slots.
As you insert the panel,
push down slightly on this
end of the panel
10. Secure the DVI or SDI replacement cover panel using
the screws you removed earlier.

2.2Installing the Bay Cat X Wall Bracket
The Bay Cat X hangs on its wall bracket in either landscape or portrait orientation.
Installing the wall bracket
The wall bracket comes with each Bay Cat X. See pic-
ture in “You Should Have These Accessories” on page 3.
Using hardware you supply, bolt or screw the wall
bracket to a wall. Be sure to bolt or screw to structural elements of the wall, not just the wall board or drywall. The
Bay Cat X weighs 73 lbs. (33 kg). The mounting method
you use must be capable of holding five times this weight
(356 lbs., 160 kg). The mounting holes are on 6.26" centers. When installed, the wall bracket protrudes 0.375" from
the back panel of the Bay Cat X.
✎ This space at the rear of the Bay Cat X will
be occupied by the wall bracket when the
display is hanging on a wall.
For array mounting guidelines, contact
Clarity Visual Systems.
Ventilation
The Bay Cat X needs no space to the rear for ventilation.
However, like all electronic devices, it does produce some
heat. The space above the display should provide enough
space so that heated air can get away. This means you
should not mount it into a sealed space with nowhere for
the heated air to escape.
Portrait or Landscape
The wall bracket always mounts the same way, whether
the displays will be hung as portrait or landscape. The
hooks on the wall bracket should always have the open part
facing upward.
✎ The Locking Wall Bracket does not have the
large back plate. It consists of the square, open
box with the locking mechanism. This Locking
Wall Bracket with CATLOCK™ is a standard
accessory.
9
2.3Hanging the Bay Cat X on the Wall
Bracket
The locking system for the Bay Cat X wall bracket prevents the display from jumping off the bracket during earth
tremors, and it helps deter theft.
Two-person job
The Bay Cat X weighs just over 73 lbs. (33 kg). Always
have two persons hang the display on the wall bracket.
Two orientations
The Bay Cat X hangs in either landscape or portrait orientation. The small black square shows the position of the
AC power receptacle. The gray rectangle shows the position of the picture connectors, when viewed from the front.
Landscape
Portrait
✎ The Bay Cat X will not rotate the picture. The
source (computer or video source) must rotate the
picture. The Bay Cat X can rotate the menus, so
the internal menus will be upright with either
orientation.
Hanging the display
Before you hang the first display, practice using the lock
lever to open and close the locking mechanism.
4. Use the locking tool to lock the display onto the wall
bracket. To see if it is locked in place, try to lift the display. If it won’t lift, its locked.
Locking and unlocking
This end of the locking tool
works from below the wall
bracket.
This end of the locking tool
works from the sides of the
wall bracket.
✎ After the display is hung, the connectors for video
and power are a little difficult to see. Some
installers connect power and video cables just
before hanging the display.
1. Be sure the locking lever is in the open position. The
tab on the lever should not protrude below the bottom
of the box.
2. Using two persons, lift the display so the power receptacle is at the bottom for landscape hanging.
✎ For portrait orientation, the power receptacle will
be on the left, looking from the front.
3. Hang the display in the hooks. Pull forward on the display to see that it is properly in the hooks.
10
Unlocking from the si de: Slide the tool in from the side. It will ride up
over the lock and catch it. Pull the lock back to unlock.
Unlocking from the bottom: Slide the tool in from the bottom, keeping the open side of the hook to the left, as shown. Catch the lock and
pull down.

2.4Connecting Power
Bay Cat X accepts 110-120 VAC and 200-240 VAC with no manual switching.
Plug the power cord into the receptacle on the rear of the
Bay Cat X. Plug the other end into a good source of AC
power.
When ready, turn on the power switch.
Power receptacle and power switch location
Normal operation
It is normal to leave the power connected and the power
switch on all the time and turn the backlight on and off as
desired.

2.5Connecting Picture Sources
The Bay Cat X accepts inputs from many different sources, depending on configuration
Which Configuration Do You Have?
The Bay Cat X can be ordered in one of three configurations: Base Model, Video Model, or Broadcast Model. The
Video Model and Broadcast Model have similar input
ports, which are described below.
Base Model Inputs
The base model has one analog computer video input
port and two RS-232 ports (input and output). You may
connect standard sources ranging from VGA to UXGA and
480i, 480p, 720p, or 1080i to the analog video input port.
Video Model and Broadcast Model Inputs
The Video Model and Broadcast Model each have a total
of five different video inputs. Of these five, four are the
same for both models: Analog, Composite, S-Video, and
Component (YPbPr).
The fifth connector on the Video Model is a DVI input
port that accepts all video and graphics signal inputs up to
165MHz pixel clock.
The fifth connector on the Broadcast Model is an HDSDI (Serial Digital Interface) input port, which accepts all
video inputs.
YPbPr sources
Component video sources, such as those provided by
some DVD players, should be connected to the component
connectors. These connectors accept 480i and 576i signals
(480p and HD signals are not accepted).
Most DVD players have red, green, and blue RCA con-
nectors for component video output.
Connectors and Locations
The locations of the connectors are shown in the illustra-
tion on page 15.
✎ For exact locations and dimensions of conne ctors,
see “Connector Locations and Diagrams” on
page 114.
Computer sources
Connect analog computer sources to the analog connector., or on Video Models, connect digital computer sources
to the DVI connector.
Since computer sources are RGB, you must set the Colorspace to RGB in the Picture menu.
Video sources
Connect composite video sources to the yellow RCA
connector, S-Video sources to the S-Video connector, and
component video sources to the red, green, and blue RCA
connectors.
Component and S-Video connectors accept NTSC and
PAL video sources. The composite connector also accepts
SECAM video sources.
✎ For some customers and field upgrades, video
boards are shipped separately and must be
installed prior to use. For more information, see
“Installing the DVI Board or SDI Board” on page 6.
14
The Video Model
The Base Model (shown above) has only
an Analog VGA connector. If the Video
Model or Broadcast Model of the Bay Cat X
is shipped outside the US, video boards are
shipped separately to reduce import duties.
The Broadcast Model (not pictured) has
SDI In/Out ports in place of the Video
Model’s DVI port
15
2.6Connecting RS232 Communication
RS232 control is not necessary for operation, but it is a convenient way to control Bay Cat Xs from a distance.
RS232 communication allows a computer to control one or
more units using the computer’s serial port. Almost everything you can do with the remote, you can do with RS232
commands. Plus, you can send inquiries to the units and
find out the current settings and values.
To connect a computer to the first unit, use an adapter on
the computer’s serial port connector to convert this to an
RJ45 connector.
1. Obtain an adapter that has a female 9-pin connector.
2. Wire it as shown in the illustration and table below.
Only three wires are required. Clip off the other wires,
or tuck them into the connector body.
Wiring the adapter
To go from 9-pin D-sub serial connector on the back of
the ccomputer to an RJ45 connector, use a standard
RJ45-to-9-pin adapter. Wire it internally as shown. The
wiring shown for this adapter is correct for straight-thru
cables. Straight-thru cables are wired 1-to-1, 2-to-2, etc.
Yellow wirepin 3
Black wirepin 2
Connecting for RS232 control
Use Cat-5 cable to connect from the computer (with the
adapter in place) to the first unit’s RS232 In connector.
From the first unit, connect RS232 Out to the next unit’s
RS232 In. Continue in this way until all units are in the
loop. The order of units in the loop does not matter because
each unit in the array must have a unique address.
✎ The loopthrough limit is approximately 30 un its in
typical situations. However, if the units are sp aced
far apart or the total length of the loopthrough is
very long, this limit may be reduced. You may
need multiple RS232 sources.
RS232 IDs
Each unit in the loop must have a unique RS232 ID.
Open the Serial Port Settings menu for each unit. On the

3.2Setting up a Bay Cat X
The source picture—from computer, video, DVD—is not always perfect in its size or resolution; it does not always
conform exactly to a standard. Bay Cat X can compensate for this.
You’ll find it easier to configure your Bay Cat Xs when you
perform the steps in the following order:
• Select the Source (Picture)
• Adjust the Input Levels
• Select the Scale Mode
• Adjust the Sharpness
• Check the Image Position
Then if you are using multiple units, whether in a banner
or an array, perform the remaining steps:
• Set up Tiling the image on multiple units
• Adjust Scaling and Cropping
• Color Balance the units
Computer sources vary quite a bit from computer to computer. They even vary between video outputs on the same
video card. Video sources vary more.
To make the Bay Cat X respond correctly to these non-
standard sources we adjust Input Levels.
• To adjust Input Levels for digital computer sources, see
page 26
• To adjust Input Levels for analog computer sources, see
page 28
• To adjust Input Levels for video sources, see page 30
How does Input Level relate to Color Balance?
To make all the displays show the same color and brightness across the whole array, you need to adjust input levels
and do color balancing.
You can do Input Levels first, or you can do Color Balance first. It doesn’t matter. But they must both be done.
What does Input Level do?
For analog computer sources adjusting to the computer’s
picture output means finding what that computer means by
black and white.
Black is supposed to be a voltage of zero coming from
the computer’s video card, but it almost never is. White is
supposed to be a voltage of 0.7 volts, but it usually isn’t
either.
The Input Level adjustment process asks you to provide
a picture from the computer that is black, then one that is
pure white. With these, you can quickly and automatically
make the display “learn” what this computer means by
black and white.
The result? Good pictures, using all the dynamic range
of color coming from the computer.
✎ For Input Levels, you must use black and white
coming from the computer you will use for the
program. Don’t make this adjustment with your
work laptop and then switch to another computer
for the display’s program of pictures.
What does Color Balance do?
Color balancing adjusts all the displays in an array so
they produce the same colors across the entire array.
Displays differ from one another because of very small
differences in the color of the light produced by the backlight and by differences in the liquid crystal panels themselves.
In color balancing you use the display’s internal test patterns of white, first, then gray. The internal pattern assures
that a pure white is used.
✎ Input Levels and Color Balan ce do not af fect each
