1.1 What are the Main Features of Bay Cat?

Flat screen, long backlight (lamp) life (60,000 hours). Portrait or Landscape orientation

Bay Cat is a 46" LCD display that can be wall­mounted or mounted on a stand. The display can be
portrait or landscape.

Landscape

Portrait

Bay Cat is only 3.9" deep. It’s aspect ratio is 1.77
(16:9). It’s native resolution is HD (1920 × 1080). It
accepts a wide range of input pictures from VGA to
UXGA in either analog or digital (DVI).

For video it accepts NTSC, PAL, and SECAM as
composite or S-Video.

Most important, it is easy to set up and adjust.

Temporary Image Retention

Burn-in causes the screen to retain an image
essentially forever, with little or no way to correct the
problem. Bay Cat does not experience burn-in, as
plasma displays do.

However, Bay Cat’s can experience temporary
image retention. This can happen when a still
image—particularly one with high color contrast—is
displayed for an extended period, usually over an
hour.

To avoid the problem of image retention, use Bay
Cat to showing moving images, or still pictures that
change regularly.

If image retention has occurred, it will be easiest to
see when displaying the Gray Test Pattern.

If this happens, use the internal Test Pattern to
display a black screen. Research at Clarity has shown
that displaying a black image, or turning off the AC
power, is the quickest way to dissipate the tempo­rarily retained image.

A black image is available from the Test Patterns
menu.

1.3 Safety for You and Bay Cat

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 be know
relating to safety:

WARNING

Wall mounts 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 71.2 lbs. (32 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, 265 lbs. (120 kg) for each display unit.

CAUTION

The screen could be damaged by heavy pres­sure.

Bay Cat screens are protected with a cover glass to
protect the LCD.

Some Bay Cats 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 Cats of this type should be
mounted where viewers cannot touch the screen.

WARNING

The backlight contains mercury.

The backlight is 40 mercury vapor fluorescent
lamps. These cold cathode fluorescent lamps behind
the LCD panel contain a small amount of mercury
(112 mg in each lamp). Follow local ordinances and
regulations for disposal.

2.2 Installing the Bay Cat Wall Bracket

The Bay Cat hangs on its wall bracket in either landscape or portrait orientation. All dimensions are in
inches.

Installing the wall bracket

The wall bracket comes with each Bay Cat. The

adapter plate is optional. See picture in “You Should
Have These Accessories” on page 4.

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 weighs 71.2 lbs. (32 kg). The
mounting method you use must be capable of holding
five times this weight (356 lbs., 160 kg).

The outer mounting holes are on 16" centers.

Ventilation

The Bay Cat needs no space to the rear for ventila-

tion. 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.

 This space at the rear of the Bay Cat will be

occupied by the wall bracket when the display is
hanging on a wall.

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, as shown in the
drawing.

12

Diagram of Wall Bracket with Adapter Plate, WAL-
4025-00, an optional accessory. (See “Optional acces­sories” on page 4)

•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.

13

2.3 Hanging the Bay Cat on the Wall Bracket

The locking system for the Bay Cat wall bracket prevents the display from jumping off the bracket dur­ing earth tremors, and it helps deter theft.

Two-person job

The Bay Cat weighs just over 71.2 lbs. (32 kg).
Always have two persons hang the display on the wall
bracket.

Two orientations

The Bay Cat 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.

Landscape

 The Bay Cat will not rotate the picture. The source

(computer) must rotate the picture. The Bay Cat 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.

Portrait

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.

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, it’s locked.

14

Unlocking from the side: 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.

2.4 Connecting Power

Bay Cat accepts 115 VAC and 230 VAC with no manual switching.

Plug the power cord into the receptacle on the rear of
the Bay Cat. Plug the other end into a good source of
AC power.

When ready, turn on the power switch.

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.

17

2.5 Connecting Picture Sources

Digital and analog computer pictures share a common connector

Computer sources

Connect computer pictures to the DVI-I connector.
This is the standard DVI digital connector, but you
can convert it to a 15-pin D-sub for analog computer
pictures with the supplied adapter.

Computer sources are RGB. Later you will set the
Colorspace to RGB in the Picture menu.

Video sources

Connect composite video pictures to the RCA con­nector.

Connect S-Video pictures to the S-Video connector.

Both connectors accept NTSC, PAL or SECAM
video sources.

 If Bay Cat is shipped to a destination outside the US,

the video inputs are disabled.

YPbPr sources

Component video sources, such as those provided

by some DVD players, should be connected to the
15-pin connector (through the adapter on the DVI
connector).

Most DVD players have red, green, and blue RCA
connectors for component video output. There is
available a cable with three BNC connectors on one
end (red, green and blue) and a 15-pin connector on
the other.

Therefore, to get from a DVD player to a Bay Cat,
you will need the following parts, listed from DVD to
Bay Cat:

1. RCA male to BNC female adapter, 3 each

2. Cable with BNC on one end, 15-pin VGA connec­tor on the other

3. 15-pin to DVI adapter (supplied)

 It may be necessary to select Analog or Digital in the

EDID menu.

The Colorspace in the Picture menu will be set to
YPbPr to see the colors correctly.

 Macrovision, a proprietary method of encrypting DVDs

so they cannot be copied, is not supported for YPbPr
component sources. It is supported for composite and
S-Video inputs. If you can’t see a DVD movie, try the
composite or S-Video outputs of the DVD player.

YPbPr supports both progressive and interlaced

scanning.

18

This adapter, supplied in the
accessories, converts the DVI
input connector to a 15-pin VGA
connector.

If the Bay Cat is shipped outside the
US, the video inputs are disabled.

19

2.6 Connecting RS232 Communication

RS232 control is not necessary for operation, but it is a convenient way to control Bay Cats from a dis­tance.

RS232 communication allows a computer to control
one or more Bay Cat displays 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 Bay Cats and find out the
current settings and values.

To connect a computer to the first Bay Cat, 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 con­necter. It not be wired.

2. Wire it as shown in the illustration and table on
the opposite page. Only three wires are required.
Clip off the other wires, or tuck them into the
connector body.

Connecting for RS232 control

Use Cat-5 cable to connect from the computer
(with the adapter in place) to the first Bay Cat’s
RS232 In connector.

From the first Bay Cat, connect RS232 Out to the
next Bay Cat’s RS232 In. Continue in this way until
all Bay Cats are in the loop.

 The order of Bay Cat is the loop does not matter.

As an example, suppose we have 10 Bay Cats in
one area divided into two groups. We might set the
ID s of the Bay Cats like this:

Group ID Unit ID

11

12

13

14

15

21

22

23

25

With this scheme, we have four ways to address
these Bay Cats:

RS232 IDs

Each Bay Cat in the loop must have a unique
RS232 ID. Open the Serial Port Settings menu for
each Bay Cat.

Set the Group ID and the Unit ID so that the com­bined ID is unique for each Bay Cat in this RS232
loop.

Addressing Bay Cats

Part of the RS232 command will be an address.

3.1 Quick Start

After you select the picture source, most of the rest of setup is automatic, although you can override
the automatic settings and adjust anything manually.

Selecting the source means choosing the connector
where the picture is coming in. In the case of the
Analog/Digital connector, it also means choosing
between Analog and Digital.

There are three input connectors:

• an analog/digital computer connector

• an S-Video connector

• a composite video connector

Quick start

Connect power and turn on the power switch, which
should light. The backlight (lamp) will come on auto­matically. If the power was already on, and the back­light is off, press the remote

ON button.

1. Aim remote control at the lower left corner of the
Bay Cat and press

SOURCE on the remote. The Bay

Cat will now look at each of the three connectors
and stop on the first one that is receiving a valid
picture.

If this is successful (it may take 10 seconds)

stop here.

If you have several sources connected, press

SOURCE again to go to the next one with a picture.

If you get no picture or have other trouble, read

the rest of these steps.

If you see no picture …

• Check the source by connecting it to another type
of display. If the source is a laptop, maybe it has
timed out and the screen is blank. Did you enable
the VGA output on the rear of the laptop?

• Check the power switch near the AC power cord.
It should be lit.

• The IR receiver for the remote is a small hole in
the lower left corner of the display. Be sure the
remote is aimed toward it. (In Portrait orientation
the IR receiver is in the upper left corner.

Landscape

Portrait

 If the source is component video, you will have to

manually change the Colorspace to YPbPr. Otherwise
the colors will be wrong.

2. Press MENU. The Main Menu should appear.

3. Select Picture with the up-down arrow keys on the

remote and press

ENTER. This will open the Pic-

ture menu.

4. With the left-right arrow keys, select the input
connector you want:

a) Analog RGB (usually computer sources, VGA

thru UXGA)

b) Digital RGB (DVI)

c) Comp Video
d)S-Video

 If the source picture is component video (YPbPr), select

the Analog RGB

5. Press ENTER. The Bay Cat will immediately dis­play the picture. Within a second or two the Bay
Cat will analyze the picture and adjust to it.

24

• Check whether EDID is set to Analog or Digital.
(See “EDID: What It Is and How It Works” on
page 34.)

About the remote

The remote control operates with IR (infra-red)
signals going to the IR receiver. The receiver is in the
lower left corner of the screen bezel behind a small
hole.

(Later, to prevent accidental adjustment of the dis­play, cover this hole with a small square of black
tape.)

A quick reference for all the remote buttons is
found in “Remote Control Buttons” on page 78.

Burn in vs. image retention

Burn-in causes the screen to retain an image
essentially forever, with little or no way to correct the
problem. Bay Cat does not experience burn-in, as
plasma displays do.

However, Bay Cat’s can experience temporary
image retention. This can happen when a still
image—particularly one with high color contrast—is

SOURCE button

displayed for an extended period, usually over an
hour.

If this happens, use the internal Test Pattern to
display a black screen. Research at Clarity has shown
that displaying a black image, or turning off the AC
power, is the quickest way to dissipate the tempo­rarily retained image.

The FREQ/PHASE button opens
the Picture menu directly.

25

3.2 Operating the Bay Cat

The Bay Cat has a cache which saves the last ten source settings.

To change sources (input connectors)

Press the
will look for the next connector that has a picture
coming in, select that one, and auto adjust to it.

Or open the Picture menu and select the source

with the left-right arrow keys.

corner. You can also disable and enable IR command

processing with an RS232 command.

To save settings

Settings (position, aspect ratio, brightness/con­trast, color balance) are saved automatically 5 sec­onds after you make a change. The system caches the
last tens settings. Whenever a picture is shown from
a new source with the same resolution as a previous
picture, the system recalls the previous settings
rather than readjust everything. This happens regard-

less of the check marks in Auto Adjust Options. (See
also “Auto Adjustment Options” on page 51.)

For example, suppose you display an NTSC picture
in the composite input and set the Aspect Ratio and
Position to your liking. Then you feed in a composite
PAL picture and set a different Aspect Ratio and a dif­ferent Position. If you then feed in a new NTSC pic­ture, the previous NTSC picture’s settings for Aspect
Ratio and Position will be used.

To “disable” the remote control

To prevent unauthorized use and adjustment of
the Bay Cat, either hide the remote, or put a small
piece of tape over the IR received hole in the lower left

Selecting the picture is really selecting the input con­nector. There are three of these connectors:

• Analog/Digital Computer

•Composite Video

•S-Video

Computer sources

Use Computer connector for either analog inputs,
the type we’ve used for years with computers, or digi­tal inputs, the newer DVI standard. Either of these
accepts pictures of the following common standards
as well as many, many others:

Typ e Re so lut io n

VGA 640 × 480

SVGA 800 × 600

XGA 1024 × 768

SXGA 1280 × 1024

WXGA 1280 × 768

UXGA 1600 × 1200

HD1920 1920 × 1080

VESA 640 × 400

Component video sources

Analog sources that are YPbPr instead of RGB are
selected in the Picture menu with “Analog,” but the
Colorspace must be changed to YPbPr Component
Video.

DVD sources

DVD players have composite video and S-Video
outputs, and they sometimes have component video
outputs from three RCA connectors. The component
output is in YPbPr form. You must select YPbPr for
the Colorspace item in the Picture menu. See “YPbPr
sources” on page 18.

Composite Video and S-Video

These two inputs accept NTSC, NTSC at 4.43/60,
PAL, PAL at SECA M video p ictu r es.

The resolution or type of source picture currently

coming in is displayed on the line just below Source.

This is grayed out because you can’t adjust it.

Analog sources

With the Analog RGB sources you can adjust Fre­quency, Phase, Brightness and Contrast and choose
the amount of Sharpness you want the displayed pic­ture to have.

The fastest, easiest way to adjust Frequency and
Phase is to press the

SETUP button. If Do Frequency

and Do Phase are checked, both these adjustments

are completed in one second.

Manually adjusting Frequency and Phase can be
accomplished if you have a checkerboard pattern on
your computer. A checkerboard is a pattern in which
alternate pixels are black and white. It is the most dif­ficult picture for the electronics to handle.

Making a checkerboard in Windows

1. Start the Paint program.

2. In the menu bar, select Image > Attributes.

3. Choose the Width and Height of the resolution in
pixels. In Colors, choose Black and White.

4. Click OK and answer Yes in the next box.

5. Near the bottom, find the row of gray shades that
starts with white. Counting the white chip is “1”,
click chip number “9”.

6. Click the spilling paint jar from the tools at the
left.

7. Click in the picture area. This picture now has
black and white pixels alternating.

Manual adjusting Frequency and Phase

1. Display a checkerboard pattern from the com­puter that will be used for program material.

2. Press

MENU, select Picture, and press ENTER.

3. Select Frequency. Use the right-left buttons to

change the frequency up and down to eliminate
vertical banding in the picture.

4. Select Phase. Use the right-left buttons to elimi-

nate horizontal streaking.

5. Exit all menus.

Digital RGB

There are no adjustments for Digital RGB sources.

Video sources

With Composite and S-Video sources you can
adjust Brightness, Contrast, Saturation and Hue. Sat­uration and Hue are best adjusted using a color bar
pattern, if one is available from the source.

Scaler Sharpness is similar to the Sharpness con­trol for Analog RGB sources. Video Sharpness is a fil­ter applied to the picture before it gets to the Scaler

manually. This works for Analog RGB sources only.

Auto mode selection

•Press

•Press

There are potential problems with any automatic sys­tem. Sometimes you may switch to another analog
RGB source that is very close to the previous one. Bay
Cat may not detect the difference and use the old
mode.

SETUP to make the Bay Cat automatically

readjust itself to the current picture.

SOURCE to make the Bay Cat look for the

next connector with a valid signal.

Manual mode selection

If the Bay Cat has trouble with an analog RGB

source, try forcing the mode manually.

 Forcing the mode works only with RGB sources that

have H&V sync. It does not work with composite sync
or sync on green.

First, you must know the mode of the analog RGB
source. Look up this mode in the table, opposite, and
open the Force Analog Mode menu.

1. In the menu, be sure Enable Force Mode is not
checked.

2. Select the Select Mode Number line and use the
+ \ – keys to choose the mode number found in
the table. (See Analog RGB Modes table on
page 94.)

 The resolution and vertical refresh rate show in the

menu in the current resolution, not the resolution of the
mode number. These numbers do not change until you
check Enable Force Mode.

32

3. Arrow down and press ENTER to force the Bay Cat
to use this mode.

Bay Cat will use this forced mode for all analog RGB
sources until this line is unchecked. When
unchecked, the automatic system will start again.

3.3.1.2 EDID: What It Is and How It Works

EDID is the name of a method computers use to determine the characteristics of the computer moni­tor.

EDID stands for Extended Display Identification
Data. It is the system behind Plug and Play. But just
knowing its name doesn’t tell you how it works.

EDID is a block of 128 bytes of data residing in a

monitor that contains information about …

• the manufacturer,

•the product ID,

• whether the monitor is analog or digital,

• video timings [resolutions],

• and color capability.

How EDID works

When a computer with EDID capability boots up,
it reads the EDID data in the monitor it is connected
to. It stores this data in the Registry (in Windows™)
where it is available to the video card.

Different video cards use this information in dif­ferent ways. Many video cards will not send video
with resolutions that are not listed in the monitor’s
EDID.

timings) than can be store in a data block of only 128
bytes. Clarity displays are capable of hundreds of res­olutions, but the EDID block has room to store only
dozens.

This means that some video cards will not put out
certain resolutions, even though the connected Clar­ity display is capable of handling them. If the resolu­tion you want to use is not listed in the Clarity
EDID, and the video card won’t list that resolution
unless it is seen in the EDID, what can you do?

A possible solution is to uncheck the Plug and Play
box in the Miscellaneous menu (shown below). This
causes the EDID to use an incorrect CRC checksum.

Some video cards will see the incorrect checksum,
assume the data is corrupted, and fall back on a
default set of timings, which may include the one you
want.

Other cards may not bother to look at the check­sum and limit the resolutions to those in the dis­play’s EDID.

Analog or digital

EDID works in either analog or digital mode, but
the Bay Cat must know which to use. You do this in
the Miscellaneous menu.

This dialog shows a setting of 1152×872 for the
1st monitor. If the #1 monitor were not capable of
this resolution, some video cards would not show
1152×872 in the dialog box.

EDID too small for Clarity displays

One problem with this system is that Clarity dis­plays are capable of many more resolutions (video

34

When EDID doesn’t work

• There is no point in changing the refresh rate in
the Display > Settings tab > Advanced menu.
The Clarity display has a fixed refresh rate of 60
Hz. It will handle other refresh rates, but the
native refresh rate it fixed. The electronics system

changes the incoming video to the display’s fixed
refresh rate.

• Be sure you the EDID for DVI/Analog settings is
correct. Some video cards with both analog and
digital outputs use only one of them, the one cor­responding to what the card read in the EDID.
The other output from the card will have nothing.

• Uncheck the Plug and Play box and reboot the
computer.

• If you must use a video resolution that is not dis­played in the Settings > Control Panel > Display
> Settings tab, and that resolution is listed in
“Tables of Modes for Analog Inputs” on page 94,
try unchecking the Plug and Play box. If that does
not help, you may have to contact the manufac­turer of the video card for help.

3.3 Manual Selection and Adjustments

3.3.2 Adjusting Levels, Computer Sources

This section applies to Analog RGB (computer) pictures only. The Levels are best adjusted semi-auto­matically.

Why adjust levels?

For analog RGB pictures the levels for black and
white vary from one computer to another, or from
one video processor to another. They even vary
between video output from a multiple-output video
card in a computer.

Your pictures will not look their best on Bay Cat
until you adjust for these differences. This is not
about adjusting color or contrast. It’s about telling the
Bay Cat what the computer or processor means by
black and by white.

Semi-automatic adjustment

1. From the computer source, display an all-black
picture.

2. Press

3. Select Input Levels and press

4. In the Input Levels menu, select Auto Black Level

5. From the computer source, display an all-white

ENTER. Wait for “Working…” to disap-

the computer that will be used for the program material.
Adjusting levels with your laptop, then connecting to
the “real” computer will not do a proper job.

Next, adjust Contrast (gain) until the Image Maxi-

mums just go to 255. Again, do not push it up after

the maximum is 255. Just touch the 255 point.b You
must adjust Brightness first, Contrast second.

If the three colors are not all at 255 (or 254), adjust

them separately.

Full automatic adjustment of levels

This sounds like the ideal solution, but it isn’t.

When the Do Black/White Levels box is checked in

the Auto Setup Options menu, the Bay Cat adjusts to
the brightest and darkest pixel in the picture. This
does not work well because:

• some pictures do not contain a pure white pixel;

• some white pixels contain “spikes,” which makes
them seem brighter than they really are, resulting
in incorrect settings.

 Black Level must be done before White Level. The

black and white pictures must come from the real
source. It doesn’t help to do this with a laptop, then
plug in the “real” computer for the program.

That completes the levels adjustments. If you have
more than one computer or other analog RGB source,
as might come from a switcher, you should do this for
each source.

Adjusting levels for computer sources manually

Send a picture to the Bay Cat that has something
completely black and completely white in it. In the

Advanced Levels menu, adjust Brightness (offset) up
and down until the values in Image Minimums just go

to zero or one. Do not push it down after the mini­mum is zero. You want to just touch the zero point. If
all three colors are not at 0 (or 1), adjust them sepa­rately in the same way.

Test Patterns. The black/white picture must come from

3.3.3 Adjust Levels, Video Sources

Video sources are adjusted best if a color bar test pattern is available from the video source: the DVD or
VCR player. If not, you will have to adjust by eye and the “feel” of the picture.

Adjusting with color bars

1. If possible, use a color bar pattern from the video
source you will use for the program material. You
cannot use the color bar from the Test Patterns
menu.

2. In the Picture menu, check Blue Only. You should
see only the alternate color bars, all of them blue.

3. Adjust Saturation to make the outer two color
bars match. Match them in brightness; they will
already match in color.

4. Adjust Hue to make the inner two color bars
match.

5. Uncheck Blue Only

 When a video source is selected, Auto Setup Options is

not available. Adjustments must be made manually.

6. If the color bar pattern has a pluge, you can use it
to adjust Brightness.

1. Choose pictures that have blacks and whites rep­resented as well as a variety of colors.

2. Adjust Contrast, Brightness, Saturation and Hue
on one Bay Cat until it looks satisfactory.

3. Adjust all the other Bay Cats in the wall so they
have the same values for Contrast, Brightness,
Saturation and Hue as the first Bay Cat.

Pluge

Adjust Brightness so you cannot
see the different between these
two marks,

but you can see the difference

3.3 Manual Selection and Adjustments

3.3.4 Adjusting Sharpness

The Sharpness control has two types of sharpness settings, one for in the Picture menu which adjusts
the scaler, and one in the Video Adjustments menu, for video sources only, which is in the video
decoder.

Sharpness for computer sources

If you are using analog or digital computer pictures
as sources, you will use only the Scaler Sharpness set­ting in the Picture menu.

In this situation, use only the sharpness settings
beginning with “RGB”:

•RGB Soft

•RGB Medium Soft

•RGB Normal

•RGB Medium Sharp

•RGB Sharp

RGB Normal is the default. It is essentially a
“pass thru” with no effect on the picture. Make any
adjustments to sharpness with the picture scaled,
that is, with the Aspect Ratio set the way you will use
it. Use Scaler Sharpness to reduce or eliminate any
artifacts of scaling.

The other is a slider in the Video Adjustments

menu.

Start with the Scaler Sharpness set to the Video Nor-
mal position.

• Video Soft

• Video Medium Soft

• Video Normal

• Video Sharp

• Video Sharp+

• Video Sharp++

• Video Sharpest

Set the Aspect Ratio to 1 to 1.

Sharpness for video sources

There are two sharpness controls for video sources.
One is the scaler described above, but with all the set­tings beginning with “Video.”

40

Adjust the Video Sharpness slider in the Video
Adjustments menu to get rid of any artifacts from the
video decoder. (Video pictures go through the decoder
first, to turn the picture into a digital form, then they
go through the scaler.)

Now set the Aspect Ratio to the one you will use in
for the program. Choose a Scaler Sharpness setting in
the Picture menu to get rid of any scaling artifacts.

3.3 Manual Selection and Adjustments

3.3.5 Position

This moves the picture image on the screen, but does not move the menus.

Position

In the Image Pan menu, the four arrow keys move

the picture.

The Horizontal Position number shows the number

of pixels from the beginning of H sync to the first
active pixel. Because there are many black pixels after
H sync, this number will not be zero when the pic­ture is at the left border of the screen.

The Vertical Position number is the number of

lines from V sync to the first active line, so it will not
be zero when the picture is at the top of the screen.

3.3 Manual Selection and Adjustments

3.3.6 Aspect Ratio

The aspect ratio of any picture is its height divided by its width. H ÷ W = Aspect Ratio

The native aspect ratio of the Bay Cat screen is 1.77,
which is sometimes referred to as 16:9. This is the
HD1920 picture format.

1920 × 1080 pixels
1920 ÷ 1080 = 1.77

Many pictures do not have this aspect ratio. Stan­dard television is 1.33 and HDTV is 1.77. Movies
from DVDs vary depending on the original film for­mat, often 1.85. The larger the number, the “wider”
the picture seems.

When the incoming picture is a different aspect
ratio from the screen, Bay Cat gives you four choices
to make it fit. (These are “radio” buttons; you can
only choose one.)

Fill Both Ways makes the picture fit top-to-bottom
and left-to-right regardless of how this stretches or
compresses the picture.

 Fill Both Ways distorts the picture, when the aspect

ratio of the incoming picture is not the same as the Bay
Cat screen, 1.66. The other three choices (below) do
not distort the picture.

Keep Aspect Ratio/ Fill One Way fills the screen
top-to-bottom or left-to-right, whichever way fits
first. If the aspect ratio of the picture is less than

1.77, such as normal TV’s 1.33, the screen will show
blank areas on the left and right.

If the aspect ratio of the picture is greater than

1.77, such as wide-screen movies of 1.85, the screen
will show blank areas at the top and bottom.

Keep Aspect Ratio/ Crop fills the screen completely
without distortion, but crops the picture on one side
or the other. If the aspect ratio of the picture is less
than 1.77, such as normal TV’s 1.33, the picture will
be cropped (chopped off) at the top and bottom.

If the picture’s aspect ratio is greater, the picture
will be cropped at the left and right sides.

1 to 1/ Keep Original Size maintains the original
size and aspect ratio of the picture. This may leave
blank areas on all four sides. For instance, a VGA pic­ture (640 × 480) will occupy only a small area in the
center of the screen. For UXGA sources, this will crop
the picture top and bottom.

44

These are examples of what happens to the
picture when the aspect ratio of the source
picture does not match the aspect ratio of
the display. This will be the case every time
the source picture is not HD1920, or some
other 1.77 source.

3.3.7 Adjusting Color Balance

Color Balance is used to match the colors of adjacent displays when several Bay Cats are arranged in a
wall. You may also use it to adjust the color of a single display.

For one Bay Cat only

If you have only one display, the Color Balance
controls can be used to set the color temperature of
the single display. Select Color Temperature in the
Color Balance menu and select from

• 3200K

• 5500K

• 6500K

• 9500K
Each of these selects a set of White Balance and Gray
Balances values to give the picture a warm (3200K) to
cool (9500K) appearance.

To adjust a wall of Bay Cats for Color Balance

Open the Backlight Control and St atus menu (

A

DVANCED OPTIONS > BACKLIGHT CONTROL & STATUS).

MENU >

a) Set Backlight Mode Control to Manual.
b) Set Backlight Intensity to 100%.

1. Open the Color Balance menu on all displays in

the wall. (

B

ALANCE).

MENU > ADVANCED OPTIONS > COLOR

a) Select Color Temperature at the top of the

menu and press the left or right arrow to get to

Custom.

b) Highlight Reset to Defaults at the bottom of

the menu and press

ENTER.

c) Highlight Test Pattern and use the left-right

arrow keys until it says White.

2. Do the previous steps on all Bay Cats in the wall.

3. When all displays are white, find the least bright
display in the wall. This will be the “baseline” dis­play, and you will not adjust it. All other displays
will be adjusted to this baseline display.

 Why pick the “least bright” display? Why not pick the

brightest and adjust to it? When the White value is 100,
the display is a bright as it can get. You are adjusting for
slight variations in backlight brightness.

4. Choose a display next to the baseline display and
adjust its White values (red, green, and blue) to
make it match the baseline display. Concentrate
on the center of the displays, not the adjacent
edges. (If you can’t bring theses settings down to
match the baseline, maybe you didn’t choose the
darkest display.) Do not adjust the Gray values at
this time.

5. Continue with other adjacent displays until all
the displays have the same appearance when
white. Be careful not to change the values of dis­plays once you are satisfied with them. Cover the
remote control holes (lower left corner of bezel) to
prevent this, or turn off the menus.

 The menus will automatically turn off after a time

determined in Menu Options (

Options > Menu Options > Menu Timeout). If Menu

Timeout is 0 (zero), the menus stay up indefinitely.

6. When all displays look the same for White,
choose the Gray test pattern in all displays.

7. Choose any display as the new baseline display. It
does not need to be the baseline display you used
for White.

8. Adjust all the displays in the Gray part of the Test
Patterns menu until they match the baseline dis­play. Do one display at a time. Again, match the
center part of the picture, not the edges.

9. When all displays match in Gray, turn off all the
Test Patterns and close all the menus.

Tips for color balancing

• Removing red has the same effect on hue as
increasing blue and green together. The Color Bal­ance menu slider bars have colored bulbs at each
end to tell you what the effect will be of moving a
color toward that end.

• Stand back from the display wall and directly in
front of it to get the overall view.

• Small changes are difficult to see at first, particu­larly with White. Change the value by 4 or 5 steps
to see the difference. If you are going the wrong
way, go back and move it 4 or 5 steps in the other
direction. If neither of these bring you closer to a
match, try another color.

• When you don’t know which color to change, pick
one at random and change it 3 or 4 steps. The
result will be either better or worse. If worse, go
the other way with that color. If that is also worse,
put this color back where you started and to the
same with another color. If everything you do
makes the match worse, you must be close to the
ideal point.

Menu Options

These controls move the menu to a different posi­tion on the screen or rotate it for Portrait orientation.
Menu Timeout is set here.

H Position moves the menus (all of them) left and
right on the screen. Use the left and right arrow keys
to increase or decrease the distance from the left side
of the screen to the left side of the menu. The num­ber indicates the how far across the screen, in per­cent, the menu starts.

V Position moves the menus up and down. Use the
left and right arrow keys (on the up-down keys) to
move the menu. The number indicates how far down
the screen the menu is in percent. It is not possible to
move the menu to the bottom of the screen.

Menu Timeout determines how many seconds the
menu will stay on the screen without any activity.
Zero means the menus will not automatically disap­per. The maximum time is 60 seconds. The shortest

50

possible time is 2 seconds. The default value, if you
have never changed Menu Timeout, is 10 seconds.

Menu Rotation makes the menus readable when the
Bay Cat is arranged in portrait or landscape orienta­tion.

 Menu Rotation does not rotate the picture. It only

arranges the menus so they read the same way the
picture does.

Auto Adjustment Options

Each of the “switches” in Auto Options can be

turned on or off by selecting it (up-down arrows) and
pressing

ENTER. When the box is checked, ;, the

action will occur under these circumstances:

• When a new source is detected that has not been
detected before. (See ’About the cache’ on this page
and “To save settings” on page 26.)

• When you press the

SETUP button.

Search on lost signal occurs only when the present
signal (picture) disappears. When this happens, the
Bay Cat will look at the other connectors to find a
valid picture.

Note that searching will not happen just because
the picture goes black. Black, from video or from a
computer, is a valid picture. The signal itself (the
sync pulses) must be lost to trigger a search.

The several Do items in this menu will, if checked,
happen in these situations:

• If a new signal is acquired, either through a search
to a different connector or because source picture
changed modes, such as from WXGA to UXGA,
each of the checked items occurs in the order
listed in the menu.

•When you press the

SETUP button on the remote,

each of the checked actions occurs in the order
given in the menu.

Do Quick Black/White Levels searches for the
brightest and darkest pixels in the picture and adjusts
to these. Black and White Levels are best done semi­automatically (see “Adjusting Levels, Computer
Sources” on page 36) so leave this unchecked.

Do Frequency and Do Phase find the frequency and
phase (separately) of the computer picture and adjust
to them. This works best on a picture that has lots of
sharp changes in brightness, such as text (adjacent
white and black pixels).

Do Position centers the picture on the screen.

About the cache

The Bay Cat has a cache for storing the most
recent attributes of the pictures it displays. When a
new picture arrives that is near enough to a previous
type, it uses the stored attributes rather than auto­matically adjusting brightness, contrast, frequency,
etc.

For example, suppose the Bay Cat sees an analog
WXGA picture and auto-adjusts everything in the
Auto Options Menu. Then you change the Brightness
and Contrast. Then you change computers and feed
in a UXGA picture.

If you now switch back to the computer with the
WXGA picture, Bay Cat will use the Brightness, Con­trast, as well as other settings, from the last time it
saw a WXGA picture.

 Aspect Ratio is global, which means it applies to all

input types. It does not change when the system recalls
a memory from cache.

Setup button

SETUP button on the remote starts the “Do”

3.5.1 Miscellaneous Options

This menu holds several unrelated settings.

Auto Backlight On turns on the backlight whenever
AC power is restored. This is normally checked.

Curtain Pattern determines what the screen will
show when there is no source picture. You have a
choice of several solid colors or the Clarity logo.

T urn Backlight Off With No Source saves electricity
and backlight life. When the source is restored, the
backlight turns on again.

Ignore RS232 CRC means that RS232 commands
will be accepted whether they have the correct CRC
check sum or not.

Enable Image Orbiting moves the image by one
pixel-size at a time to prevent or alleviate temporary
image retention.

When a high-contrast, still image is displayed for a
long time on Bay Cat, it sometimes happens that the
image is retained temporarily. To recover from this,
display a black picture, such as the black test pattern,
for a while until the retained image can no longer be
seen.

If still pictures are unavoidable, reduce the possi­bility of temporary image retention: turn on image
orbiting.

This moves the picture in 9 positions, each posi­tion only one pixel from the next. It has the same
effect as using the position control to move the pic­ture.

How does orbiting occur? These are the 9 pixel
positions:

from this memory, if the values for the new source
are close to values already stored.

This saves time, because the Bay Cat does not
have to go search through the mode table and adjust
to the frequency and phase of the new signal.

However, when the new source is close to but not
quite exactly like a previous source, the Bay Cat may
chose a set of values from the memory that are not
correct. The picture may be cut off on one edge or too
small for the screen.

If this happens repeatedly, select Clear Input Mem-
ory and press

When image orbiting starts, the picture is assumed
to be in position 5. It moves to position 1, then
moves to each position in the order shown. The pic­ture stays in each position for 30 seconds.

Clear Input Memory erases the 10 input memories
for a fresh start.

When a new mode is encountered, the Bay Cat
adjusts to it and saves those settings in a memory. As
input pictures with different modes are sent to the
analog or DVI input, the Bay Cat uses the values

3.5.2 Backlight Control and Status

Backlight control can automatically adjust the screen brightness as ambient light conditions change.

Backlight control has two options: automatic and or
manual. In the manual mode, you adjust the back­light brightness to suit ambient conditions that are
not likely to change.

In the automatic mode, you let the ambient light
determine the image brightness. This is useful when
the Bay Cat is in a location that sometimes has day­light which, of course, varies.

When there is more light in the area of the Bay
Cat, the screen will have to be brighter to see it
clearly, and the backlight intensity will be 100%.
When there is less ambient light, the screen can be
darker and still be read easily. This is the low inten­sity setting which is a percentage (50 to 100%) of the
maximum backlight brightness.

The look of the Backlight Control and S tatus menu

depends on whether it is in manual or auto mode.

CAUTION

Changing a failed backlight is a job for a quali­fied service technician. It is done at the factory,
not in the field. Contact your Clarity dealer.

Auto backlight control

1. Set the Backlight Control Mode to Auto.

2. Set the Ambient Threshold to a ambient light level

at which the backlight will switch to low inten­sity.

3. Set the Low Intensity at the level (in percent of

maximum) you want the backlight to have when
the ambient light falls below the threshold.

The Ambient Light at the top of the menu measures

the ambient light in Lux. As long as this number is

above the Ambient Threshold number, the backlight

will be 100%.

When the Ambient Light is below the Ambient
Threshold, the backlight go to the Low Intensity set-

ting.

Manual backlight control

This mode is useful when the Bay Cat is in a room
with no outside windows and no lighting control.

1. Set the Backlight Control Mode to Manual.

2. Adjust the Backlight Intensity to comfortable

brightness. A lower brightness will increase lamp
life.

3.5.3 Force Analog Mode

Sometimes the automatic mode detection process is unable to detect the mode satisfactorily. In these
rare cases you can force the Bay Cat to use a particular mode.



Mode forcing applies to Analog RGB pictures only. The
menu does not work for digital or video pictures.

The automatic mode detection works very well
almost all the time. In those rare instances when it
does not produce a satisfactory result—the picture is
tearing, very noisy, folded over on itself, or the wrong
size—you should first try to fix the problem before
forcing the mode:

• Check the Resolution in the Picture menu. Is it
what you expect?

• Check the picture at the source. In Windows, look
at the display settings.

•Press

• If the picture appears stretched in one direction,

SETUP to initiate automatic mode detection

look at the Aspect Ratio menu. Set it to 1 to 1 /
Keep Original Size. The picture may not fill the
screen this way, but it should not be distorted.

If none of the above adjustments fix the problem, you
can try forcing the mode.

 Forcing the mode only works if Retry On Lost Signal is

checked in the Auto Setup Options menu.

1. Determine the mode of the source you are using:
resolution and vertical refresh rate.

2. Find this mode and its Mode ID number in the
three tables starting on page 94.

3. With Enable Force Mode not checked, select the

mode number.

4. Now check Enable Force Mode.

 The Resolution shown in this menu is the resolution of

the mode number shown in the top line. The currently
active mode is shown in the bottom line.

5. If this forced mode does not work well, try
another similar mode. Check again the specifica­tions of the source picture you are trying to dis­play.

Tables of Modes can be found at “Tables of Modes for
Analog Inputs” on page 94

3.5.4 Serial Ports Settings

This applies only if you use RS232 commands to control the Bay Cat.

If you wish to control Bay Cats remotely with RS232
commands from a computer, read this section. Other­wise, skip it.

Bay Cats can be linked together for RS232 using
straight-thru 8-conductor cable with RJ-45 connec­tors. This is the common type of LAN connection
cable, not null-modem, sometimes call Cat-5 cable.

Adapter from computer to RJ45

At the computer end, you will need an adapter to
go from the computer’s 9-pin serial output connector
to a female RJ45 connector. Electronics stores have
these ready-to-wire types. Buy one with a female
9-pin sub and connect the wires as shown.

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.

Setting the ID

Each Bay Cat in the RS232 series needs a unique
ID so it can be individually addressed. The ID is in
two parts, Group ID and Unit ID. Each of these has a
range of 0–9, A–Z. This range results in 1296 possi­ble addresses.

You can group the Bay Cats by using the same let­ter or number of the Group ID, such as 8. In this way
you can address the group as 8*, and all the Bay Cats
in the string that have Group ID 8 and any Unit ID
will execute the command. See the RS232 program­ming guide for Bay Cat (part number 070-0108-02 or
later) on www.ClarityVisual.com/login/

.

1. Click the lower, blue button.

2. Use the name “tech” and password “help”.

Response type and terminator

The ASCII Response Type determines what type

of data will be returned to the computer. For human
readable text in a serial program choose Symbolic. For
computer-read data you can use Numeric or Data
Only.

The ASCII Response Terminator will be deter-

mined by what you serial program wants to see at the
end of every transmission from the Bay Cat.

Baud Rate must be the same as that used by the
controlling computer. The baud rate is not automati­cally set, as it is with modem communications. It
must be manually set here and at the computer to
match each other.

order you string them together. Most RS232 signals
easily travel up to 150 ft. (50 m) between Bay Cats.

Diagnostics for RS232

The Fans & Diagnostic Values menu has two

items that concern RS232:

• Last RS232 Packet T ype will usually be Operation

or Event, but it might be Error.

• RS232 Packets Received is a counter of the num-

ber of messages received by this Bay Cat, whether
they were addressed to it or not. It is not resetta­ble. It counts up to 32767 and then wraps to 0.

3.6 Cleaning the Screen

The screen is covered with a protective acrylic sheet.

Clean the screen with a soft cloth or lint-free paper
towel and a mild cleaning solution. Ordinary window
cleaning products, such as Windex™, are safe.

CAUTION

Prevent liquid from running down the screen
and leaking into the interior of the Bay Cat.
Spray liquids on the cloth or towel, not directly
on the screen.

CAUTION

If you use a cloth towel, be sure it is clean. If
the towel was used to clean counter tops or
anything else, it may contain grit which could
scratch the acrylic screen protector.

To set levels semi-automatically, display a black pic-

ture from the source computer. Choose Auto Black
Level and press ENTER. Then display a white picture
from the source, choose Auto White Level and press

ENTER.

The Bobcat is now adjusted to the brightest and dark-

est picture this one source can produce. If you
change the computer to a different one, or change
the video card in the computer, you should do this
adjustment again.

LEVEL key opens the

Input Levels menu
directly, when the
source is Analog.

To set levels manually, display a black picture from the source computer.

Select Manual Black Level and adjust it until one of the three colors just
touches the 0 value. Then adjust the other two colors until they just touch 0
also. Do not push this value “lower” than 0, because the number will not
change, but the picture will get worse.

Now display a white picture from the source computer. Select the White lev-

els and adjust them until the value just touches 255. Do not push them
“higher” than 255, because the number will not change, but the picture will
get worse.

63

Video Adjustments

Scaler Sharpness is similar to the Sharpness control for Analog

RGD sources.

Video Sharpness is a filter applied to the video picture before it

gets to the Scaler Sharpness filter.

Blue Only is used with source color bars for adjustment. It is

visible only when the source is Comp Video or S-Video.

Aspect Ratio

The Bobcat’s aspect ratio is 16:9 or 1.77. This menu decides how to

handle source pictures that have other aspect ratios.

Fill Both Ways — Picture is stretched in one direction to make it fit.

This will cause some distortion, unless the source is 1.77.

Keep Aspect Ratio / Fill One Way — Picture is expanded until it

reaches the first border (sides or top-bottom). No distortion, but
extra space is filled with black.

Keep Aspect Ratio / Crop — Picture is expanded until it reaches the

second border (sides or top-bottom), and the rest of the picture
goes off the other edges (is cropped). No distortion, but some parts
of picture are lost from view.

1 to 1 / Keep Original Size — Picture is pixel-for-pixel as it is in the

source. No distortion, but extra space is filled with black.

66

WALL key opens

the Aspect Ratio
menu directly.

Message In Picture

Recall Last MIP displays (turns on) whichever message last

appeared.

Timeout range is 0 to 60 seconds and is the length of time

before the message will disappear. 0 seconds means there is
no timeout, and the message will not automatically disappear.

Messages are stored in the Bay Cat only through RS232. See
