INTRODUCTION
The TView PresoCard from FOCUS Enhancements puts
PC-to-TV video conversion technology into the smallest
and lightest form factor available on a personal computer.
The PresoCard PC-to-TV video converter fits into any PC
laptop Type II or Type III PC Card slot for unparalleled
mobility. Because every ounce makes a difference when
you travel, the PresoCard is ideal for the mobile exhibitor.
It delivers big screen impact without the size and weight
associated with presentation monitors and portable pro-
jection devices.
The TView PresoCard offers the ultimate in portability.
No power adapters, no cable collection, no carrying case.
And you’ll stay in control of the image positioning, filter-
ing and video output of your PC through an easy to use
software control panel. But that isn’t the only way the
PresoCard is good for your image. Custom image stabi-
lization techniques and 3-line averaging make you look as
brilliant as the 16.7 million colors on your television.

you must utilize a VCR with Comp. Video or S-Video

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 match-
ing port until you feel its latches engage.
• If you wish to use a separate VGA or Multisync moni-
tor while using the PresoCard, attach the monitor’s 15-
pin 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 cam-
eras 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.

To determine whether or not your television or VCR sup-
ports 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 dis-
play 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 S-
video device to the wrong port may damage your equip-
ment.
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 sup-
ports 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 mis-
take these input ports for the ones used for Video Out.
