Connecting the TView PresoCard
Cable
This cable can only be attached one way.
• Attach the cable’s VGA Input port to your laptop’s
VGA Monitor Out port and tighten the thumbscrews.
• Attach the PresoCard Interface connector to the
PresoCard. Press this connector into the card’s matching port until you feel its latches engage.
• If you wish to use a separate VGA or Multisync monitor while using the PresoCard, attach the monitor’s 15pin cable to the VGA Pass-through connector on the
PresoCard cable.
TView PresoCard provides two
major connection-types:
S-video
A high-quality video connection used by some video cameras and VCRs. The connector on an S-video cable has a
round plug with several small metal pins and plug into
the S-video output port on the back of the computer.

Page 19
FOCUS Enhancements TView PresoCard User’s Manual
To determine whether or not your television or VCR supports S-video look for a port on your device that matches
the S-video output port on the back of the computer. This
port on your external device may or may not be labeled as
S-video in. S-video is recommended for external video display because of its higher picture quality capability.
WARNING: The S-video connector resembles other computer connec-
tors such as those used for a printer, modem, mouse, or
keyboard. When using an S-video cable make sure to plug
it only into the S-video output port. Connecting an Svideo device to the wrong port may damage your equipment.
Composite video
A connection type used by most televisions, VCRs,
laserdisc players, and certain LCD panels. The connectors
on a composite video cable have an RCA-type plug with a
long metal pin projecting from the center of the plug and
plug into the composite video out port on the back of your
computer.

To determine whether or not your television or VCR supports composite video look for a port that matches the
composite video out port on the back of your computer.
This port on your television or VCR may or may not be
labeled as video in.
NOTE: Your computer may have also come with hardware that
allows you to input video from an external source. In this
case additional ports for S-video input and composite
video input will also be provided. Make sure not to mistake these input ports for the ones used for Video Out.

FOCUS Enhancements TView PresoCard User’s Manual
Using the optional audio
out connection
It is important to remember that both the S-video and
composite video cables only carry the video signal out
from your computer. In many cases the built in speakers
that came with your Macintosh computer or monitor are
better for presentations than the ones found in the television. However, if you also want sound from the computer
to go to the VCR or television you need to use an additional cable; miniplug-to-dual RCA-plug cable. This cable is
required if you want to record sound along with your presentation on to a video tape.
This cable connects the Sound output port on the back of
your computer to the Left and Right Audio-In ports on
either your television or VCR. In the following illustrations, the optional audio connection using the miniplugto-dual RCA-plug cable is shown along with the required
video connection.

CONNECTING TO YOUR TELEVISION
You will need either an S-Video cable or Composite Video
cable to connect your TView PresoCard to your television.
Step 1: Look at your TVs Video Input ports. Identify
whether your TV has an S-Video input, a Comp. Video
input or an RF input.
A. If your TV has an S-Video input, attach one end of
the S-Video cable to the S-Video port on your TView
PresoCard cable and attach the other end to the S-Video
input port on your television.
B. If your TV has an Comp. Video input, attach one end
of the Comp. Video cable to the Comp. Video port on
your TView PresoCard cable and attach the other end
to the Comp. Video Input port on your television.
C. If your TV has an RF input but no other inputs, you
must utilize a VCR with Comp. Video or S-Video input.
If you do not have a VCR with Comp. Video or S-Video
input, you must obtain an RF Modulator from Radio
Shack (part number 15-1283, see “RF Modulators,
VCRs, and You” in the Reference section at the end of
this manual).
16
You may use both S-Video and RCA outputs at the same
time (to send video to two televisions, for example).
Step 2: If desired, connect your computer monitor’s 15-pin
cable to the 15-pin VGA Pass-through port on the
TView PresoCard cable.
Step 3: Turn on your Television. Set your TV to “AUX” or
“Video Input.” Video In can usually be set by remote
control, with a button labeled TV/Video, Line In, Input
Select, Video, AUX, or similar. Sometimes Video selection takes place in an onscreen menu system.You must
make sure to set your TV to an Input channel instead of
a numbered channel, such as channel 3, because channel 3 is an RF channel, not a Video channel (RF
Modulator and VCR users should leave the TV on
Page 23
FOCUS Enhancements TView PresoCard User’s Manual
channel 3, as detailed in the Reference section at the
end of this manual). If necessary, consult your TV manual or manufacturer for more information on Video
Input. When you have set your TV to Video In, you will
probably see an indicator such as VIDEO or AUX in
colored letters in the corner of your TV screen.
Step 4: The computer’s image should now pop up on the
TV. If it isn’t, check the Reference section of this manual
for tips on configuring your computer’s settings to activate the TView PresoCard. You’ll also find up-to-date
tips and advanced information on our Website at

Section 4: Reference
BASIC TIPS FOR ADVANCED PRESENTATIONS
Good presentations are part art and part science, but experienced, successful presenters tend to follow these guidelines:
Keep it simple.
Use large pictures and characters.
Use large type: At least 18-point size.
Use motion to add interest to your presentation.
Avoid intense backgrounds. Pastels provide palatable con-
trasts.
Use solid colors for backgrounds. Increase the color choices
by using video cards that support more colors.
Avoid red colors. Reds do not display as accurately as
greens or blues.
On PAL televisions avoid large areas of bright color.
Changing to NTSC output may eliminate panel flicker.
Don't use the entire screen. Leaving space around the edges
accommodates different video formats and overscan.
Rehearse. Run through your presentation several times.
Practice using the Electronic Marker and the features of
your own presentation package until they become second
nature.
Get there early. Set up well before the class or meeting
begins. Check for overscan on the television or video projector you'll be using. Make adjustments ahead of time.

VCRS, RF MODULATORS, AND YOU
Connecting to a VCR
To use your VCR to connect a TView PresoCard to your
TV, first find the Comp. Video cable and S-Video cable.
Then connect either the Comp. Video cable or S-Video
cable from the TView PresoCard to a port on your VCR
labeled “Video Input” (also known as AUX IN, or AV IN it will probably be a yellow RCA/Phono type connector
on the back of your VCR). Now find the connector on your
VCR marked ANT Out, To TV,or RF Out. This port usually has a Cable-TV type cable screwed in, connecting it to
your TV. Next, tune your TV to channel 3 or 4, and turn
on your VCR. Find a button on the front of the VCR called
Line, TV/Video, Video Input, or similar and press it. If
your VCR does not have a button to specify Video In, try
to find an onscreen menuing system with your VCR’s
remote control. Then confirm that your computer is
turned on and the Scan Converter has its power light lit.
20
RF Modulators
If you do not have a VCR with Comp. Video or S-Video,
you need a special adapter called an RF Modulator. This
device converts the Comp. Video signal from your TView
PresoCard to an Antenna Signal, which can then be tuned
in on your TV using Channel 3 or 4. FOCUS Technical
Support recommends the Radio Shack RF Modulator,
available under Radio Shack part number 15-1283.
Advanced Setup
This section serves as a compilation of suggestions and
tips we have collected while using Video Converter products here at FOCUS Enhancements. These Hints and Tips
are designed to improve the picture quality of your television, help you better understand your Video Converter,
and give you some insight into special features.
Page 27
FOCUS Enhancements TView PresoCard User’s Manual
Recording Audio to the VCR
If your computer has an Audio Out port, you can simultaneously record all computer sounds or music to videotape.
An extra cable (FOCUS Part number 444-1315) is needed
to connect the audio from the computer to the television
monitor. The sound-out port on most computers is a standard stereo mini-jack (headphone type) connector. If your
TV or VCR has an Audio In port, connect the computer’s
sound-out port to the TVs Audio In RCA port with the
FOCUS Audio Patch Cable. Attach the other end of the
audio cable to the Audio In on your television monitor or
VCR.
Choosing a Desktop Pattern (Themes)
Because of a television’s relatively low resolution, some
desktop patterns can produce bizarre effects. If undesirable, avoid using desktop patterns with very intricate
designs or single color dots. As an alternative, use either a
black Desktop Pattern, a limited gray design, or a simple
solid pattern with only a few muted colors. In our experimentation, fine lines produce a wildly flickering display,
while solid darker colored patterns prove to be most effective for a stable image.
Better Font Display
Perhaps the most important step to ensure readability is to
increase the point size of the display font in the Desktop.
We recommend a size of 14 point or higher. Windows
users can install software from our TView PresoCard disk,
which includes TV Fonts and a Windows 95 Desktop
Theme called TV.
Closed Circuit Television
If you plan to use L•TV over a closed circuit network or
with a cable longer than 25 feet it is essential to use a video
distribution amplifier. These types of amplifiers can be
found in most consumer Television and HiFi stores, such
as Radio Shack.
21
Page 28
FOCUS Enhancements TView PresoCard User’s Manual
Connecting Multiple Televisions
When connecting several television monitors together use
a video “loop through” cabling method as illustrated
below. Make sure the last television monitor in the chain is
terminated (many television monitors have a video termination or “loop” switch). If your total cable length will
exceed 25 feet (or 8 meters) it may be necessary to use a
video distribution amplifier.
FREQUENTLY ASKED QUESTIONS
What is a Video Converter?
FOCUS Enhancements Video Converters are portable,
external devices that allow you to convert your computer’s video signal into a television signal so your monitor’s
picture can be displayed on any television. Your Video
Converter will support DOS, OS2, Windows 3.1, 3.11,
Windows 95, and most Macintosh systems.
How does the Video Converter connect to a computer?
Video Converters connect to desktop and laptop computers through the 15-pin VGA or Macintosh RGB port.
How does a Video Converter connect to a television set?
FOCUS Enhancements Video Converters are connected to
a television with an RCA connector (“composite video” or
“Video In”), S-Video connector, or a type F (antenna) connector with an RF modulator. S-Video is a special high
performance input utilized by some televisions and VCRs
produced in the last few years. S-Video is a round connector with 4 pins. We recommend using S-Video input if
your television is equipped with one.
If your television has neither composite Video In or SVideo but has a type F (antenna), you will need to purchase an RF Modulator to convert from an RCA jack
(Video In) to a type F (antenna) connector. We recommend
the Radio Shack model number 15-1283. Connect the
Video Out from the FOCUS Enhancements Video
Converter to Video In on an RF modulator and set the
22
Page 29
FOCUS Enhancements TView PresoCard User’s Manual
modulator to Channel 3 or 4. The modulator then connects
to your television set using the type F (antenna) cable. The
television set needs to be set to the same channel as the
modulator (3 or 4).
Do FOCUS Enhancements Video Converters work with
large screen televisions?
Yes. The size of the television is not relevant to its ability
to display an NTSC signal. Any television that can accept
a composite video signal from a VCR can accept a signal
from your FOCUS Enhancements Video Converter.
What causes colors in the white letters on my television?
This is a characteristic of the NTSC television standard.
Historically, when color was added to black and white
broadcasts, the color information was overlaid on the
black and white signal. Because of this overlay, some televisions become confused and can’t tell whether elements
of the signal are meant to contain color or brightness information. This confusion results in color rainbows seen in
the small white letters and some other pictures. These
effects generally are not noticed in broadcast pictures
which have large objects, complex scenes, and motion.
Using an S-Video input with the FOCUS Enhancements
Video Converter will minimize this condition.
Will I see a color picture on the television if I have black
and white laptop?
Yes. If your laptop has a VGA or Macintosh RGB output
port, it will support color operation when it is connected a
color monitor or television.
Will I see the picture on my computer monitor and the
television simultaneously?
FOCUS Enhancements Video Converters provide a VGA
passthrough cable or port that enables viewing of your
television and VGA monitor at the same time. Some older
laptops will not allow simultaneous use of the television
and the laptop screen.

screen on it, but the edges
are overflowing. How can
I fix this?
This condition is called
Overscan. Your television
can only display a resolution of about 608x432 with
standard Video
Converters.
If your Video Converter
has the FOCUS Hardware
Compression button

“Compress” and only
available on certain models - check your manual),
you can fit 800x600 or up

Problem
Everything is connected
properly, but the TV only
shows snow. What's
wrong?
My TV does not have a
Video Input connector that
matches the cables with
my Video Converter. The
TV only has an ‘Antenna
In’ connector. Do I need
an adapter?
Can I use my VCR to connect a Video Converter to
my TV
I see the computer image
on the TV, but the image
has a far lesser quality
image than my computer
monitor. Is my Video
Converter broken?
Reason
The input source of your
TV needs to be set to
“Video Input” instead of a
numbered channel, such as
channel 3.
Yes. You need a special
adapter called an RF
Modulator. (If you have a
VCR see the note below.)
Yes. To use your VCRs built-in RF Modulation, connect the Composite or S-Video cable from the Video Converter
to the Video Input (also known as Aux IN, or AV in - it will probably be a yellow RCA/Phono type connector on
the back of your VCR). Now make sure your RF output is connected to your TV. Then tune your TV to channel 3
or 4, and turn on your VCR. Find a button on the front of the VCR (or remote control) called Line In, TV/Video,
Video Input, or similar and press it to activate video in.
No, your Video Converter is just fine. A television can provide only 30 frames per second. A computer monitor
provides over 60 frames per second. Merging these two media has always been technically very challenging.
These two very different frame rates cause flicker, and RGB color reduction. FOCUS Enhancements’ engineering
team develops the best Video Converter technology available today. Our products dramatically reduce the flicker
and provide the highest color transfers possible.
Windows 95
Video In is usually specified with your remote control, with a button labeled
TV/Video, Line In, Input
Select, or similar.
Sometimes the Video selection takes place in an
onscreen menu system. If
necessary, consult your TV
manual or manufacturer
for more information on
Video Input.
This device converts the
Composite Video signal
from your Video
Converter to an Antenna
Signal, which can then be
tuned in on your TV using
Channel 3 or 4. FOCUS
Technical Support recommends the Radio Shack RF
Modulator, available
under Radio Shack part
number 15-1283.

Can I use my Video
Converter to watch television on my computer monitor?
My Macintosh does not
have a Monitor Out connector. Is it possible to
make a Video Converter
work with one-piece
Macintoshes?
Your Video Converter is a one-way device for converting a computer video signal into an NTSC (also known as
Composite) video signal.
Yes
You need to contact Apple
Computer and ask for a
Video Out Connector for
your particular Macintosh
model.
