video phone calls using VDONet’s

INSTALLATION

You’ll need these items from your
BigpictureTM box:
NTSC camera video capture card
Bigpicture CD-ROM

of the hardware and software in your

hardware (video capture card and camera)
must be installed before the software.
Determining Your Version of
Windows 95
There are different versions of Windows 95
on the market. One of the primary ways these
versions differ is in the way they handle the
addition of new hardware. Follow these steps
to determine your version of Windows 95.
This information will be important during
installation.
1. Click the My Computer icon on your
desktop with the right mouse button.
2. Click Properties.
INSTALLATION

3. In the “System Properties” screen, look at
the system information under the General
tab (circled in the following screen image).
The number following the text “Microsoft
Windows 95” will end with “950”, “950a”,
or “950b”. This indicates your version of
Windows 95. Write this number on the
blank below for future reference. Then
click OK.

Inserting the Video Capture
Card into Your Computer
NOTE: Before installing your
capture card, write down the card’s
serial number in this space:
________________________________
You will find the serial number
underneath the bar code on the white
sticker on the capture card and on your
Bigpicture package. If you ever need to
call our technical support department,
the technical support representative
will ask you for this serial number.
This number will help him or her
identify your capture card.
Your video capture card supports Plug and
Play installation, the fastest, easiest way to
add new hardware to your PC. Windows 95
should do all the work of detecting your new
hardware.
TIP: Before you unplug anything,
label the cords or make a sketch of how
things are connected. This can be
helpful when you plug things back in
later.
1. Turn off your computer and unplug it from
the electrical outlet.
2. Unplug any peripheral devices (printer,
monitor, keyboard, mouse, etc.) from the
computer.
INSTALLATION
5
CAUTION:To avoid risk of
electric shock, make sure your
computer and all peripheral devices are
turned off and unplugged from
electrical outlets.
3. Remove the screws from your computer’s
cover and then remove the cover. Your
computer may not resemble the computer
in the following diagrams, but the basic
principle for removing the cover should be
the same. Refer to your computer’s
documentation if you need further
instructions.
4. Touch an unpainted metal part of your
computer (the back panel, for example) to
discharge any static electricity you may be
carrying. Static electricity can damage
electronic components.
INSTALLATION

5. There should be two types of expansion
slot inside your computer, ISA and PCI
(see the following diagrams). Find an
empty PCI slot inside your computer. PCI
slots are usually white plastic grooves lined
with silver metal. ISA slots are usually
longer black plastic grooves lined with
silver metal.

6. Unscrew and remove the expansion slot
cover (the long, narrow piece of metal that
keeps dust from entering through the
opening perpendicular to the slot). Be
careful not to drop the screw into the PC.
7. Holding the video capture card at each
corner, with the gold edge facing the slot,
push the card down as gently as possible
until it snaps into the expansion slot. You
will need to apply some pressure to
properly fit the capture card into the
expansion slot. A gentle back-and-forth
motion helps seat the card all the way into
the slot. If you feel resistance, do not force
the card into the slot. The card may not be
properly aligned with the slot. Remove the
card completely and try again.
