1.3 Safety 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

2.1 Installing 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
Page 13
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.

2.2 Installing 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
Page 16
2.3 Hanging 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.

2.5 Connecting 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
Page 21
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
Page 22
2.6 Connecting 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 wire pin 3
Black wire pin 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

3.2 Setting 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

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
other, but they both affect the final picture.
• To color balance the displays, see page 46
✎ If you have a stand-alone app lication, you don’t
need to do color balancing, but you can use the
Color Balancing menu to adjust the color to your
preferences. Nonetheless, you should still set
Input Levels.

3.2.1 Selecting the Picture
Selecting the source (picture) manually is usually quicker than using the SETUP button.
Selecting the picture is really selecting the input connector.
If you have the Base Model, you have only one connector,
which is a HD-15 for analog computer sources. If you have
either the Video Model or the Broadcast Model, you have
the following additional connectors:
Video Model
(DVI Board)
Digital SDI
Component (YPbPr) Component (YPbPr)
Composite Composite
S-Video S-Video
Broadcast Model
(SDI Board)
Computer sources
Use the HD-15 connector for standard analog inputs, the
type we’ve used for years with computers. For digital
inputs, use the DVI connector. Either of these accepts pictures of the following common standards as well as many,
many others:
Type Resolution
VGA 640 x 480
SVGA 800 x 600
XGA 1024 x 768
SXGA 1280 x 1024
1360 x 768
1366 x 768
UXGA 1600 x 1200
HD1920 1920 x 1080
VESA 640 x 400
Component video sources
Component video sources are assumed to be YPbPr.
DVD and component video sources
DVD players have composite video and S-Video outputs, and sometimes have component video outputs from
three RCA connectors. Component video sources are
assumed to be YPbPr, so you do not need to specify the
colorspace.
Composite Video and S-Video
These two inputs accept NTSC and PAL. The Compos-
ite connector also accepts SECAM video.

3.2.2 Adjusting Levels for Digital Computer Sources
Digital sources do not normally need adjustment, but the controls are there if you need them.
These controls are advanced level controls and should not
be adjusted unless you have been briefed by the factory or
are familiar with black level adjustments. They are used to
correct the digital blacks that come from video cards that
have incorrect levels.
✎ Don’t use these controls unless you have been
briefed by Clarity or you are familiar with black
level adjustments. These controls are usually not
necessary.

3.2.3 Adjusting Levels for Analog 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 outputs
from a multiple-output video card in a computer.
Your pictures will not look their best on Bay Cat X until
you adjust for these differences. This is not about adjusting
color or contrast. It’s about telling the Bay Cat X what the
computer or processor means by black and by white.
Semi-automatic adjustment
1. From the computer source, display an all-black picture.
This must come from the computer source that will be
used for the program. It does no good to use your lap-
top for this adjustment, then connect to a different computer for the program. Nor can you use the Bay Cat X’s
black test pattern. (Hint: Display a black screen using
Windows Paint program.)
✎ To adjust levels for UXGA sources that will be
displayed in One to One scale mode, perform your
adjustments using Fill All scale mode and then
switch back to One to One.

5. In the Input Levels menu, select Auto Black Level and

the process is complete.
6. From the computer source, display an all-white picture.
7. In the Input Levels menu select Auto White Level and
press
ENTER. Wait for “Working…” to disappear.
The Bay Cat X is now adjusted to the black and white
levels of this computer using this video card. If you
change computers or video output cards in the computer, you must do this again.
✎ 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.
Full automatic adjustment of levels
Automatic adjustment of black and white levels does not
do as good a job as manual adjustment of levels. By select-
ing Do Black/White Levels box is in the Auto Setup
Options menu (Main Menu > Advanced Options > Auto
Setup Options), the Bay Cat X adjusts White levels and
Black levels to the brightest and darkest pixel, respectively,
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.
IF
Advanced Options
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
and save the configuration to a memory slot.
Adjusting levels for computer sources manually
1. Display an all-black picture from the source computer.
✎ You cannot make these adjustments using the
internal Test Patterns. The black/white picture
must come from 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 Maximums just go to 255. Again, do not push it up after the
maximum is 255. Just touch the 255 point. You must adjust
Brightness first, Contrast second.
If the three colors are not all at 255 (or 254), adjust them
separately.

3.2.4 Adjusting Levels for 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 the picture
1. Select a video source in the Picture menu.
2. Press
LEVEL on the remote.
✎ These controls are also used for analog sources
when you chose YPbPr Colorspace.
Now you have two choices.
• Adjust using any picture from the video source.
• Adjust using a standard color bar pattern from the
source.
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 Main Menu > Picture > Input Levels 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
6. If the color bar pattern has a pluge, you can use it to
adjust Brightness.
Pluge
Adjust Brightness so you cannot see
the different between these two
marks,
but you can see the difference
between these two marks.
✎ When a video source is selected, Auto Setup
Options is not available. Adjustments must be
made manually.
30
Adjusting with any picture
This procedure must be done after you adjust color bal-
ance (page 46).
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 X until it looks satisfactory.
Page 37
3. Adjust all the other Bay Cat Xs in the array so they
have the same values for Contrast, Brightness, Saturation and Hue as the first Bay Cat X.

3.2.5 Aspect Ratio and Scale Mode
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 X screen is 1.77,
which is sometimes referred to as 16:9. This is the WXGA
and HDTV picture format.
1366 horizontal pixels, 768 vertical pixels
1366 / 768 = 1.77
Many pictures do not have this aspect ratio. Standard
television, VGA, SVGA, and XGA signals are 1.33. 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 X gives you six choices to make it
fit. To select the scaling mode, go to Main Menu > Aspect
Ratio & Wall > Scale Mode.

Fill All makes the picture fit top-to-bottom and left-to-right
regardless of how this stretches or compresses the picture.
Fill All distorts the picture, when the aspect ratio of the
incoming picture is not the same as the Bay Cat X screen.
Letterbox/Pillarbox expands the picture until the first
“
edges (top-bottom or left-right) touch the border of the display, and then fills in the other sides with a solid color.
Crop expands the picture until the second edges touch the
border and let the other edges of the picture fall outside the
display and get cropped.
Widescreen (16x9) forces the aspect ratio to 16 x 9 (1.77),
the standard for many DVD movies. This will distort any
picture other than 16X9 aspect ratio pictures. Widescreen
can be used to display anamorphic DVDs on an array.
Normal Video (4x3) forces a 4 x 3 (1.33) aspect ratio, the
ratio of standard television. Normal Video is used to display YPbPr video on the analog input port. Its resolution is
720x640 which is not 4x3 but it should be displayed as 4x3
(the pixels aren't square).
One to One 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.

3.3 Tiling a Display
Whether you use Clarity’s Big Picture™ or an external video processor, your goal is to make the picture fit
together properly at the edges.
Using an external processor
The processor divides a single picture into several sections and sends each part on a separate cable. Connect these
cables to the proper Bay Cat X.
You can still position the picture with the Bay Cat X
controls, or, with most processors, position and zoom the
picture with the processor controls.
Using Clarity’s Big Picture™
To show the same source on all the Bay Cat Xs in an
array you’ll need to use an external distribution amplifier.
For each unit, set the Aspect Ratio & Wall menu for the
same array size.

Program Information
Wall Width and Wall Height are the number of units
wide and high for the picture. This may be different from
the physical array size. You could build a 4x4 array of
Bay Cat Xs and use Wall Mode to put a single picture on
the four cubes in the upper left corner, for instance.
• Unit Column and Unit Row represent the position of
the Bay Cat X in this “array.” For example, in a 2 x 3
array of Bay Cat Xs, the unit at the top left corner of the
array would have a Unit Column value of 1 and a Unit
Row value of 3
• Wall Mode, when checked, turns on the Clarity Big
Picture™ feature. When not checked, the unit shows
the whole picture.
✎ Each unit in a “array” gets the whole picture by
feeding them all with a distribution amplifier. The
Aspect Ratio & Wall menu tells the unit what
portion of the entire picture to display.
Frame Compensation
When video units are used in an array, the intent is to
display a large version of an image. However, even the thin-
“
nest of mullions break up the image oddly.

One way around this is to adjust the image. Imagine
looking out a window made up of many panes of glass. The
image you see is partially obscured by the frames, but your
mind assembles the image and ignores the frames.
Frame compensation allows you to mimic the mind’s
function by “hiding” portions of the picture (as if the mullions were actually hiding the image) and allow the distributed image to appear as one very large image.
To hide pixels to the left and right of images, set Frame
Width.
To ensure that images containing diagonal lines remain
correctly diagonal, turn on Frame Compensation.
Depending on how closely you space the units, you must
determine how much of the picture to “hide” behind
Bay Cat X’s mullions and the space between units.
WARNING
The Bay Cat X generates heat. Plan your
array installation to provide adequate ventilation or cooling to ensure that your Bay Cat Xs
operate within normal usage guidelines. For
more information, see “Optimizing Your Clarity
Display” on page 116.
If you have any questions about your installation, consult Clarity Visual Systems for proper Bay Cat X array
configuration guidelines.
To hide pixels at the top and bottom of images, set
Frame Height.

3.4 Saving Your Work & Recalling a Memory
Some saving is done automatically, but there are big advantages to saving your work manually.
How automatic save works
Whatever changes you make with the remote control or
RS232 commands, these changes are saved automatically.
If you change sources (switch to another input connector)
and come back to this source, everything you did before
will be “recalled.” Things will look like they did before.
Suppose you make adjustments to an SVGA source on
Analog 1, then you feed a UXGA source to Analog 1 and
make new adjustments. Then you switch to the S-Video 1
connector and do some more setup for it.
Later you switch to the Analog 1 input again, and this
time it has the SVGA source from before. The Bay Cat X
will recognize that it has seen this source before, or at least
a source with these characteristics, and will recall the
SVGA settings you established before.
This kind of recall includes Input Levels, Position, and
Frequency, but it does not include Wall Mode and any Big
Picture adjustments you made. Those need to be recalled
from memory slots.
Manually saving to memory slots
Bay Cat X has 40 numbered memory slots, and this is
the best way to save. Recall is fastest from memory slots.
First, set up the Bay Cat X the way you want it, including all the adjustments listed in this section. Then press the
SAVE button twice. This opens the Save grid.
Navigate to an unchecked slot number, or to a checked
slot if you want to overwrite what’s already saved. Press
ENTER.
This menu shows all the data that will be saved. You
can’t change anything but the name in this menu. To save
immediately, press
ENTER. The appearance of this menu is
somewhat different for digital and video sources, reflecting
what is saved for them.
Use the left-right arrow keys to navigate along the line.
Use the up-down keys to change the character at that point.
Press
PREV when finished. Then select Save Now and press
ENTER again.
If you have RS232 control, there are commands to send
a string name to a memory slot, saving time.
How to recall a memory slot
1. Press
SAVE once to open the Recall grid.
2. Navigate to the slot you want to recall. You can only
land on slot numbers that are not empty (have checks).
Press
ENTER to open the Recall detail menu. If this slot
number has exactly the same settings are currently
being used, a (Current) message appears on the top line.
3. The only line you can select is Recall Now. Press
ENTER.
Advantages of saving configurations to memory slots
• You can compare multiple settings quickly
• You don’t have to repeat settings when comparing
entire configurations
• You can revert to a known good setting when testing
new configurations
To change the name of the memory slot
The default name is an abbreviated description of the
contents. In this case, the name tells you that the source is
connected to Analog 1, which is an XGA picture. This unit
is part of a 2x2 array, and it’s the unit lower left corner (column 1, row 2).
If your customer wants or needs a more descriptive
name, select the Name line and press
40
ENTER.

3.4.1 Memory: What Is Saved? And Where?
Bay Cat X’s automatic memories work well, but the best way to save and recall is with the numbered memory
slots, because they recall everything.
In the Bay Cat X some parameters (values) are associated
with the mode. The mode is primarily the horizontal and
vertical resolution and the vertical frequency of the incoming source picture. It is more than this, but if you think of it
this way, you will be close enough.
Some parameters are associated with the input. The
input in this instance means the input connector: Analog 1,
Digital, Composite Video, etc.
✎ The parameters specific to Mode and Input are
saved in memory slots.
Some parameters are global, that is, they are not associated with either the mode or the input connector, and are
not saved to memory slots. They are universal.

connected to Analog. Then later, using the same input connector but a different computer you set up the Bay Cat X
for a 1600x1200 @ 60Hz. You re-adjust the Black and
White Levels, because they are different.
Still later you plug in the first computer with its
1024x768 @ 65Hz picture. Immediately, the Bay Cat X
recognizes that it has seen this signal type before, and it
recalls the Black and White Levels from its internal memory.
42
Page 49
It does not Do Frequency or Phase or anything else,
because it recognizes that this input was used before, and
the previous settings are probably correct.
Possible issue with Mode specific memory
Suppose that after setting up the 1024x768 and
1600x1200 pictures, you connect a third computer that is
1024x768, but it has a different requirement for Black and
White Level. In this case, the Bay Cat X would use the
default values for these levels.
To prevent this from happening, use the memory slots as
described in “Saving Your Work & Recalling a Memory”
on page 40.
Switching input connectors
Now suppose you use Digital to bring in a picture that
uses the component YPbPr video. You change the Colorspace setting to YPbPr. If you switch back to Analog in the
Picture menu, the Bay Cat X switches back to the RGB
Colorspace, because Colorspace is specific to the input
connector.
Possible issue with Input specific memory
What happens if you switch back to Analog and the picture there is YPbPr? The Bay Cat X has no way to know
this, no way to detect the difference between RGB and
YPbPr, so it will use the wrong Colorspace.
To prevent this from happening, use the memory slots as
described in “Saving Your Work & Recalling a Memory”
on page 40.
Global parameters
In none of the examples above does the Bay Cat X try to
change the Baud Rate or the Color Balance values, because
these items are saved globally.

3.4.2 Scaling and Cropping
Sometimes the picture does not fit the array. If the source picture is video from a DVD, the aspect ratio is probably
1.77 (16x9), the same as HDTV.
✎
The aspect ratio of a picture is its width divided by
its height. 1024 ÷ 768 = 1.33
The aspect ratio of a Bay Cat X is 1.77 (16x9), the same as
HDTV. When the source picture’s aspect ratio is not the
same as the Bay Cat X array, you have to do something to
make the picture fit. You have some basic choices:
• Fill the area both ways. This will produce some distortion in the picture. Circles will not be round.
• Put the picture in without distortion and crop off the
sides (or top and bottom).
• Put the picture in without distortion and fill the extra
space with black or some other solid color.
• Force an aspect ratio, such as 16 x 9 or 4 x 3.
Below is a 1.77 picture shown on a 3x3 array of
Bay Cat Xs. The picture fills the array nicely, and there is
no distortion or cropping.
Scale Mode determines how the picture will be made to fit
the array.
• Fill All means that the picture will touch the borders of
the array all around, even if this means stretching (and
distorting) the picture in one direction. The picture had
to be stretched sideways to fill the screens.
• Letterbox means expand the picture until the first
edges (top-bottom or left-right) touch the border of the
array, then fill in the other sides with a solid color.
• Crop means expand the picture until the second edges
touch the border and let the other edges of the picture
fall outside the array and get cropped. Here the width is
filled, there is no distortion, but the top is cropped off.
This would happen when the Justify is B
OTTOM.
Let’s start with a 1.33 (4x3) picture, the aspect ratio of normal TV, and put it on this same array of Bay Cat Xs. Here
is the original picture.
44
• Widescreen means force the aspect ratio to 16 x 9
(1.77), the standard for many DVD movies.
• Normal forces a 4 x 3 (1.33) aspect ratio, the ratio of
standard television.
Justify determines how the picture will be placed in the
array.
• If the picture is too wide for the array and is cropped on
the sides, you can choose Left, Center, or Right.
Page 51
• If the picture is too tall for the array and is cropped top
and bottom, you can choose To p, Middle, or Bottom.
• Similar choices are made if the picture is letterboxed.
Border Color determines the color of the “extra” space
around the picture if it doesn’t fill the screen. The choices
are:
• Black
•White
•Red
•Green
•Blue
• Dark Red
• Dark Green
• Dark Blue
When the Scale Mode is Fill All, the Border Color line will
be grayed out, because there will be no border.

3.4.3 Adjusting Color Balance
Color Balance is used to match the colors of adjacent displays when several Bay Cat Xs are arranged in an
array. You may also use it to adjust the color of a single display.
For one Bay Cat X only
If you have only one display, the Color Balance controls
can be used to set the color temperature of the single display.

Understanding Color Temperature
Different "Pure white" light sources do not always have
the same color. For instance, light from an incandescent
bulb is much more yellowish than light from direct sunlight. "Color Temperature" is a way of measuring these
color differences. In general higher color temperature numbers are more bluish or "cooler". You may have a reason for
wanting your unit to be a specific color temperature. For
instance, if you are using your Bobcat X in a television studio where you will be videotaping the content, you will
want a low color temperature. The default color temperature for the Bobcat X is 8500k. This is the native color temperature of the LCD panel. You may choose a different
color temperature by setting it in the Color Balance menu.
46
Page 53
Adjusting Color Temperature
Select Color Temperature in the Color Balance menu
and select from 3200°K (Warm), 5500°K, 6500ºK, and
8500°K (Cool).
Each of these selects a set of White Balance values to
give the picture a warm (3200K) to cool (9500K) appearance.
To adjust an array of Bay Cat Xs for Color Balance
The object of color balancing is to make the individual
units in an array show the same colors. When we see a yellow car move across a video array from one display to
another, we want it to have the same color for the whole
trip, not change from yellow to maroon to orange.
The displays naturally have slightly different colors
from one display to the next, because of slight variations in
the backlights and LCDs. This cannot be avoided, but we
can compensate for it with color balancing.
Color balancing is subjective. It may seem strange at
first, but it gets easier with practice. Fortunately, you don't
have to match all the colors; you only have to match whites
and grays.
When you make all the displays look the same with
White and Gray, all the other colors will look the same. It is
not necessary to achieve a perfect white or a perfectly colorless gray. It is only necessary that all the displays look
alike when they display white and gray.
CAUTION
Never try to match the colors of the display
units with the Black and White Level controls
or with the Video Controls. You will not like the
results if you do.
Color Balancing
1. Turn on all the units in the array and let them warm up
for at least five minutes. The lamps must be thoroughly
warm before you color balance.
2. Open the Backlight Control and Status menu (
> A
DVANCED OPTIONS > BACKLIGHT CONTROL).

Backlight Control Mode Manual

MENU
a) Set Backlight Mode Control to Manual.
b) Set (or confirm) Backlight Intensity to 100%.
3. For each Bay Cat X in the array, do the following:
a) Open the Color Balance menu on all displays in the
array. (
MENU > ADVANCED OPTIONS > COLOR BAL-
ANCE).
✎ If the array has never been color balanced, make
sure you start with the same color temperature
setting on each unit. If you are not interested in
achieving a specific color temperature, use the
default of 8500K, which is the brightest. If the unit
has been color balanced before, it will display
C
USTOM in its color temperature setting, because
the balance values don’t match any of the pre- se t
color temperatures.
b) Highlight Test Pattern and use the left-right arrow
keys until it says White.
✎ Always use the internal Test Patterns for color
balancing, not an external pattern.
4. When all displays are white, find the least bright display in the array. 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.
5. 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
47
Page 54
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.
6. 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. Use Hide Menu to keep from setting
other displays and allow you to see more of the white
field. To unhide the menu, press E

8. Choose any display as the new baseline display. It does
not need to be the baseline display you used for White.
9. 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.
10. When all displays match in Gray, close all the menus.
The test pattern automatically turns off.

• 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 array 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.

About the input memories
The Bay Cat X has a ten input memories 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 X 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 X will use the Brightness, Contrast, as
well as other settings, from the last time it saw a WXGA
picture.
✎ You may capture a portion of the image or the
entire screen; the larger the area captured the
longer the process.
2. On the Logo Capture menu (Main > Advanced >
Capture Custom Logo) select Position to specify the
on-screen position for the custom splash screen.
Choices are:
Middle Left Centered top/bottom at the left side of the
screen
Middle Center Centered on the screen, both top/bottom

✎ It may help to set the Scale Mode to one to one in
the Aspect Ratio menu before starting the logo
capture. (although it will work from any scale
mode). This will allow you to visualize the true size
of the captured image relative to the screen.
3. Select Scaling to specify the aspect ratio of the cap-
tured image. Choices are:
✎ The larger the capture image (in number of pixels,
not scale mode) the slower it will be to draw.
Repeated pixels draw faster than non repeated so
a higher RLE factor can also increase draw speed
somewhat.
5. Move the capture area (indicated on screen by the red
rectangle) to the portion of the screen you want to capture.
a) Select Move Area Up/Down or Move Area
Right/Left and then use the + and - keys to position
the upper right corner of the red rectangle to the
upper right corner of the image.
6. Resize the red rectangle by selecting Shrink/Grow
Width and Shrink/Grow Height and using the + and -
keys to increase or decrease the size of the red
rectangle.
one to one Each captured pixel of the logo will appear
as one pixel of the display regardless of how

For example, if you capture a logo from a

pixels of the 1920x1080 pixel logo screen.
full screen The captured image will be stretched until it
fits the output screen in one direction, without changing the aspect ratio. This is analogous to the “letterbox/pillarbox” choice in the
aspect ratio menu
n percent The image will be scaled somewhere in
between the two choices above. 10 percent
is a little bigger than one to one, 20 is bigger
than that etc.
4. Select RLE Compression Factor to reduce the bitsize
of the image.
RLE (Run Length Encoding) is a very simple method
of compressing an image where multiple pixels that are
the same will be stored as a count and a value rather
than as individual pixels, thus saving space. The RLE
Factor is the number used to determine when a pixel is
“the same”. As long as each color of the new pixel is
within the RLE factor of the old pixel it will be considered the same. For analog images, it is best to put the
RLE factor at 1 so that the analog noise will be eliminated and a flat image can be compressed. There are
only 576 kilobytes available for the captured logo
which is not large enough for a full screen image without compression. If you get the error message that the
logo is too large, you can try increasing the RLE factor.
However, the results will probably be more blurry than
you may like.
✎ The background color for the logo will be the color
of the pixel in the upper left corner of the capture
area. This background color will be used even if
the scaling is set to full screen, since the aspect
ratio of what they captured will probably not be the
same as the screen. The captured image will
reach to the outside of the red line. There's a “bite”
taken out of each corner to allow you to better see
what's under the line.
7. After you have sized and positioned the selection rect-
angle, select Start Capture.
The screen displays the following note:
Capturing Logo...
Capture can take several minutes
Unit will not respond to comman ds during capture
✎ The larger the image, the more time it will take to
capture. Capture can take up to 5 minutes, during
which time there is no response from the unit. The
reason for this is that the logo gets capture d to the
same FLASH part that the embedded firmware
resides in. You can't write to the FLASH and read
from it at the same time.
54

8. When capture is complete, the following note displays:
Logo Capture Complete
9. On the remote, press M
ENU to dismiss the note and the
Logo Capture menu from the screen.
10. To see the custom splash screen, on the remote, press
CURTAIN. Depending on the size of the captured
image and the positioning choices, the logo may take
up to a minute to display.
11. To return to the input source, press CURTAIN again.
✎ The custom logo is also available from the Test
Patterns menu (Menu > Diagnostics > Test
Patterns > Logo).
Logo capture guidelines
It is difficult to say what is the largest size logo you can
capture. There are 576 kilobytes of memory set aside for
the logo (at 16 bits per pixel), which can hold an image of
about 576x512 pixels, but this varies depending on how
much it can be compressed. However, large or high resolution images draw quite slowly, so you may be happier with
a lower resolution image scaled up to the size you want.
As an example, the Clarity logo you see on the splash
screen is 666 pixels wide and 213 pixels high scaled one to
one. If you have an image you would like to use for a logo,
you can open it in a graphics application (such as Paint or
Adobe Illustrator) on a computer connected to the Bobcat
X.
On the Bobcat X, from the Scale Mode submenu
(Main > Aspect Ratio & Wall), set the Scale Mode to
One to One and you will see your logo at the size it will be
if you set the logo capture Scaling to One to One. If it
appears too small, set the logo capture scaling to a higher
value. If you wish to stretch your logo as big as it can be on
the screen set the scaling to Full Screen. You may need to
capture a few times at different settings to find what looks
best.
If the logo draws too slowly or is too large, try reducing
the size of your image using your graphics application program, capturing the smaller image, and using the Bobcat
X's scaling mode to scale it to the desired size.

Preferred Source Detection
Analog computer video cards provide only vertical and
horizontal frequencies. Sometimes, this is not enough
information. Bay Cat X receiving such “ambiguous” signal
modes, in certain cases, could misinterpret the resolution to
be any of three different modes. For example, 1024 x 768,
1280 x 768, and 1360 x 768 all have the same respective
horizontal and vertical frequencies but represent different
aspect ratios, 4 x 3, 15 x 9, and 16 x 9. By specifying the
correct source detection mode, Bay Cat X can correctly
interpret the signal and display the incoming image in the
proper aspect ratio. The native aspect ratio of Bay Cat X is
16 x 9, and the default resolution is 1366 x 768.
(or fiftieth) of a second. If the image is static, such as with
computer graphics, it is quite simple to put the fields back
together. However, if the image is moving, it can cause
problems because an image will have moved from the time
the even lines arrive to when the odd lines arrive. A special
piece of electronics known as a deinterlacer can analyze
whether an image is moving or stationery and use mathematical algorithms to put the two image fields together in
the best way. The Bobcat X has deinterlacer electronics to
take care of standard definition television signals. However,
it does not have deinterlacer circuitry for high definition
television (1080i). The “HD Interlaced Content Motion”
control gives the regular electronics some help in determining how to put together the two fields if you are viewing
1080i. Keeping this setting at “Normal” works best for
most images. This will assume the image has no fast
motion. The only time you will see a problem with this setting is if you are at native resolution (i.e. you are using a
Baycat X or your scale mode is set to one to one on a Bobcat X). In that case, you may see something of a "zipper"
effect on the edge of moving objects. To get rid of this,
change the setting to "Rapid". However, if you do, you will
probably see static images flickering slightly (known as
“twittering”).
Another alternative to minimize both effects is to
keep the setting at Normal and set overscan (in the
Aspect Ratio menu) to 1%. This will turn on the scaler
and minimize the zipper effect.For more information
about the Miscellaneous options, see “Miscellaneous Settings” on page 97.
HD Interlaced Content Motion
HD Interlaced Content Motion is a control you probably
won't need to touch. Here is an explanation of it.
Some video signals, most notably those made for television, are what is known as “interlaced”. At one moment in
time, only the even number lines of image are transmitted
to the display. At the next moment (usually 1/30 or 1/25 of
a second later) the odd numbered lines are transmitted.
These two moments in time are known as fields. On CRT
television sets, the even field persisted on the phosphor
long enough so that by the time the odd field got there, our
eyes put it all together into one picture. On digital displays
such as Bobcat X, the electronics reassembles the odd and

Backlight Control Mode Auto
Backlight Intensity 100
Ambient Threshold 99Lux
Low Intensity 30
1. Set the Ambient Threshold to a ambient light level at
which the backlight switches to low intensity. Thus, if
the ambient light drops, the backlight dims.
2. Set the Low Intensity at the level (in percent of maxi-
mum) 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%.
Backlight control has two options: automatic and 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 X is in a location that sometimes has daylight
which, of course, varies.
When there is more light in the area of the Bay Cat X,
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 (30%
to 100%) of the maximum backlight brightness.
The look of the Backlight Control menu depends on
whether it is in manual or auto mode.
58
✎ Ambient Light is a relative value, and is pertinent
only to the Bay Cat X. It is not an absolute value.
You may get different ambient light values with a
handheld light meter.
When the Ambient Light is below the Ambient
Threshold, the backlight dims to the Low Intensity set-
ting. Bay Cat X has a nominal time delay of three minutes
before changing light levels. This time delay prevent flick-
ering if the ambient light level is near the Ambient
Threshold.

Manual backlight control
This mode is useful when the Bay Cat X is in a room
with no outside windows and unchanging ambient light levels.
Set the Backlight Control Mode to Manual.

3.5.3 Serial Port Settings
This applies only if you use RS232 commands to control the Bay Cat X.
If you wish to control Bay Cat Xs remotely with RS232
commands from a computer, read this section. Otherwise,
skip it.
Bay Cat Xs can be linked together for RS232 using
straight-through 8-conductor cable with RJ-45 connectors.
This is the common type of LAN connection cable, not
null-modem, sometimes call Cat-5 cable.
RS232 is also used to upgrade the firmware of the unit.
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.
Yellow wire pi n 3
Black wire pin 2
Connect all the Bay Cat Xs together through their
RS232 ports: from the computer to the first Bay Cat X
RS232 IN; from the first Bay Cat X RS232 OUT to the next
Bay Cat X RS232 IN, etc. It doesn’t matter what order you
string them together. Most RS232 signals easily travel up to
150 ft. (50 m) between Bay Cat Xs.
Setting Unit IDs
Each Bay Cat X in the RS232 series needs a unique ID
so it can be individually addressed. To set unit IDs, go to

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 Cat Xs 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 Cat Xs in the string
that have Group ID 8 and any Unit ID will execute the command. See the RS232 programming guide for Bay Cat X

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 computerread data you can use Numeric or Data Only.
The ASCII Response Terminator will be determined
by what your serial program wants to see at the end of
every transmission from the Bay Cat X.
Baud Rate must be the same as that used by the con-
trolling 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.
✎ For firmware upgrades, you don’t need to adjust
the baud rate.

Input system caches
Settings (position, aspect ratio, brightness/contrast,
color balance) are saved automatically 5 seconds after you
make a change. The system caches the last ten 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 hap-
pens regardless of the check marks in Auto Adjust
Options. (See also “Auto Adjustment Options” on
page 52.)
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.

4.1 Cleaning the Screen
Clean the screen with a soft cloth or lint-free paper towel and a mild cleaning solution.
Cleaning products and how to use them
For protective glass and the LCD screen itself, a foam
spray cleaner seems to work well. It’s is sold under different names in different parts of the world. It is available
from many janitor supply companies or building maintenance supply companies. Ask for
• Claire #50 glass cleaner, or
• Sprayway #50 glass cleaner
It is probably sold under a local name, but it all comes
from one company. If you ask for either of the two names
above (it is sold under both), you will get this cleaner under
the local name.
This cleaner is good on glass (screens, lenses, mirrors)
and acrylic (screens).
Spray it on the protective outer glass, but not on the LCD
itself. For LCDs, spray it on the cloth, not the screen.
CAUTION
Prevent liquid from running down the screen
and leaking into the interior of the Bay Cat X.
Spray liquids on the cloth or towel, not directly
on the LCD.
Paper towels tend to leave lint. A better paper towel for
cleaning is Scott
paper towels are generally available at auto parts stores,
home fix-it stores, and hardware stores.
®
Shop Towels. These blue, lint free,
Wipe the mirror or screen gently with a lint-free cloth or
lint-free paper (see Cloth below). Turn the cloth over to the
dry side and continue wiping to take up the haze.
• Glass Wax™ is another good cleaner for mirrors and
glass screens, but it does not work well on acrylic
screens. It is a liquid in a can. You spread it on, let it
dry, then wipe it off.
• Windex™
screen. (See Warning above.)
Cloth to use
White cotton cloth is better for cleaning than colored
cloth. The dyes in some colored cloth tend to make it less
absorbent.
works well, too. Just don’t spray it on the
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 protective glass.

The resolution of an analog signal is
determined from an internal mode
table and the measured horizontal
and vertical frequency of the signal. If
the incoming signal does not conform
to the one found in this mode table,
the resolution can be adjusted. This
should not normally be necessary.
The Range depends on the input signal. A default frequency is obtained
from an internal mode table depending on the horizontal and vertical frequency of the signal. The frequency
can then be adjusted if the signal
does not match the one in the internal
table. Automatic frequency adjust-
ment will also change this setting.
Phase The position of the pixel clock relative to the start of the line. 0 – 360 degrees in 32 steps.
Sharpness A setting for how sharp image edges are on an image that is
scaled to fit the screen. Primarily used for low-quality video
images. High-quality video and digital image will not benefit
from this setting.

Menu Item Description Setting(s)
Scale Mode Fill All makes the picture fit top-to-bottom and left-to-right regardless of how this stretches or compresses
the picture.
Letterbox/Pillarbox expands the picture until the first edges (top-bottom or left-right) touch the border of the
display, and then fills in the other sides with a solid color.
Crop expands the picture until the second edges touch the border and let the other edges of the picture fall
outside the display and get cropped.
Widescreen (16x9) forces the aspect ratio to 16 x 9 (1.77), the standard for many DVD movies. This will
distort any picture other than 16X9 aspect ratio pictures.
Normal Video (4x3) forces a 4 x 3 (1.33) aspect ratio, the ratio of standard television. Normal Video is used
to display YPbPr video on the analog input port.
One to One maintains the original size and aspect ratio of the picture. This may leave blank areas on all
four sides. For more information, see “Aspect Ratio and Scale Mode” on page 32.
Justify Justify determines which portion of a cropped picture to be cropped. Center
crops equal portions from the top and bottom (or sides). Bottom/Right crops off
just the top (or left). Top/Left crops off just the bottom (or right).
For letterboxed pictures, Justify determines the position of the image on the
screen. Center centers the image, Bottom/Right puts it at the right of the
screen (or bottom). Top/Left puts it at the top of the screen.
Overscan Zooms the image a small amount so that the outer edge is chopped off all
around. Conventional television sets overscan anywhere from 5 to 20%. A television picture shown with no overscan may have objectionable lines or other
extraneous noise on the outer edges of the picture. By agreement among the
broadcast industry, for standard definition television, no titles or text will be
chopped off with as much as 20% overscan. No important action will be
chopped off with as much as 10% overscan.

Asset Tag An optional user settable field which is set via the RS-232 port. This could be a serial num-
ber, name or an y ot he r pi e c e o f information desired
Backlight Status Shows OK if the electronics module detects that both banks of backlights are functioning
normally. Shows Failed if one or both of the backlight banks is not drawing the correct
amount of current
Internal Temperature The current internal temperature at one point on the electronic module. This is not neces-
sarily the highest nor the lowest temperature point of the unit, nor is it an indicator of ambient temperatures.
If thermal guidelines (see “Normal Use Thermal Guidelines” on page 116) are exceeded
and additional ventilation or cooling has been implemented, this temperature may be used
as a datapoint to determine if the temperature of the unit is being affected.
Mode ID The index into the internal mode table found for the incoming signal. This is used in diagno-
sis of mode detection problems
HPer The measured horizontal period of the incoming signal. This is used in diagnosis of mode
detection problems
VLines The number of horizontal lines detected per vertical period. This is used in diagnosis of
mode detection problems

Last Packet Type The kind of packet that was last received. When using the ASCII RS-232 protocol,
the possible types are operation, event (for KY packets) and OEM (for ST packets)
but other types are possible when using the binary protocol (for internal and diag-
nostic use only)
Last Packet Address This Unit Alone – The last packet was addressed to this unit and no others. It will be
acted on and answered
Global -- The last packet was addressed to this unit and also to others. It will be
acted on but not answered.
Not This Unit – The last packet was addressed to a unit or units other than this one.
It will not be acted on or answered
Not Addressed – The last packet was received with address -- or via the binary non
addressed protocol. It will be acted on and answered. If multiple units are con-
nected on the RS-232 chain, the answer may not be properly received, since all
units on the line will be “talking” at once.
