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

Inserting the Video Capture
Card into Your Computer
NOTE: Before installing your
capture card, write down the card’s
serial number in this space:
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.
________________________________
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.

INTERNET SECURITY ISSUES

The Internet is an amazing new frontier of
Your Bigpicture package allows you to tap
into the Internet’s vast resources for
human interaction. Almost anyone and

another. This is part of the appeal of gaining

exchanging and accessing video imagery,
voice information, and other data. While
3Com cannot be responsible for any injury to
your security or privacy or any security
difficulties you may encounter resulting from
your use of your Bigpicture equipment, we are
concerned about our customers’ security and
thus would like to make you aware of some
possible ways you can manage your privacy in
this dynamic arena.
However, the public and free nature of the
Internet can raise some of the same concerns
for one’s personal security that any public
activity might generate. This includes security
of your system and its files, your identity and
that of your family and friends, and the data
you send over the Internet. The security of
those receiving information from you is also to
be considered.

Internet based software that you

and use it to send you information that you
do not wish to receive.
VDOPhone appears on the CD-ROM in
your package. It allows you to tap into a
network of other VDOPhone users. When
you use this software, you are asked to
provide information about yourself and
your Internet address.
· Use a dynamic IP address when
using the Internet. When you are
transferring information on the Internet, you
are sending out information about your
Internet address, often when you don’t
even realize it. This can be helpful when
you are dealing with family, friends, or

directory while the VDOPhone software is
running on your PC. Adding information to
the VDOPhone “Identity” section might
help friends and family identify who you are
for practical reasons. However, keep in
mind that someone you don’t know can
use your information to call you and send
you information that you may not want.
Many ISPs offer dynamic IP addresses for
users who are concerned about security.
We strongly encourage you to obtain one
and to obtain them for anyone using your
Bigpicture system.
The best solution for this potential problem
is to talk to your Internet service provider
(ISP) about obtaining a dynamic IP
address. Dynamic IP addresses change
with every call to your ISP. What they
allow you to do is to send and receive
information over the Internet that can be
traced. If someone were to intercept your

than your real name to ensure that no one
will know who you really are.
· Use a password your children don’t
know. If you have children who use your
computer, you may want to keep your
VDOPhone password a secret from them
to ensure that they don’t have access to the
software. Unsupervised, a child could
access video under the “(X) Adult Only”
category with just a few clicks of a mouse.
· Do not use an actual picture in the
photo ID section of VDOPhone setup.
In VDOPhone setup, you have the
opportunity to choose an ID photo of
yourself to attach to your video messages.
We recommend that you NOT use an
actual photo of yourself or any of your
family members. This is another way you

unless you disconnect your camera and
microphone.
· Do not use “Auto Answer” when
using VDOPhone. This setting
automatically brings up any video images
that enter the VDOPhone directory,
regardless of whether you want to see
them or not. By disabling this feature, you
reduce the risk of seeing something that
might offend you or that you do not wish to
see.
Implementing these precautionary procedures
are just a few ideas that may help ensure your
privacy and security on the Internet. Always
remain aware of the public nature of the
Internet when using software that utilizes its
resources.
“Call Screening” enables you to see the
identity information of the person calling

IRQ Conflicts: Freeing an IRQ
Your video capture card requires two system resources: an interrupt and a memory segment. If your system
is not immediately detecting the card, there is a high probability that there is an IRQ conflict involving the
video capture card. In the Windows Device Manager, double-click the Sound, video and game
controllers option. Look for the “U.S. RoboticsÒ Video Capture” item. If there is a yellow circle with an
“x” or an “!” inside, Plug and Play discovered an IRQ conflict during installation. Plug and Play will not
always alert you when such conflicts arise.
If your system indicates such a conflict, follow these steps to rectify the problem:
1. In Device Manager, double-click U.S. Robotics Video Capture. A “U.S. Robotics Video Capture
Properties” window will appear.
2. Click Resources.
3. Write down the setting for the interrupt. (If no interrupt is listed, Windows 95 was unable to find a clear
interrupt. If an interrupt is listed, make sure the interrupt is not also being used by a non-Plug and Play
device or REAL MODE device driver. If it is not, then your problem may be unrelated to an interrupt
conflict.)
37
TROUBLESHOOTING AND ONLINE HELP RESOURCES
NOTE: If your PC is loaded with many devices, there may not be a free
interrupt available for the video capture card. If this is the case, you’ll need to find
an unused device which has a reserved interrupt and free that interrupt for use by
the capture card. Many PCs reserve an interrupt for a PS/ 2 mouse or an IDE hard
disk controller, even when these devices are not present on the system. If an
interrupt is reserved for a device that you know is not present on your system,
that interrupt can be reserved for your video capture card.
4. Go into your BIOS and disable the peripheral not being used (i.e., the PS/2 mouse or IDE controller
mentioned in the preceding sidebar).
5. Enter Device Manager, highlight the device, then click the Remove button.
6. Restart Windows 95.
7. Examine the Plug and Play configuration. Your video capture card should be assigned to the IRQ you
requested in the Device Manager.
38
TROUBLESHOOTING AND ONLINE HELP RESOURCES
IRQ Conflicts: Altering PCI BIOS Settings
Your BigpictureÔ package is a PCI-based system. While most PCI-based systems configure themselves
automatically via a Plug and Play compliant chip set and BIOS, there are occasional problems. Some of
these systems require you to configure some or all of the following functions, usually by changing jumpers on
the system board or BIOS setup parameters. (Check your system manual for information on configuring
these functions.)
· The PCI slot must be configured to support bus-mastering.
· The PCI slot must be configured to support INTA (PCI Interrupt Class A).
· The PCI INTA must be assigned to a free IRQ or set to “Auto”.
· Ideally, the PCI slot should be set to LEVEL Trigger rather than EDGE Trigger.
On some systems, a specific IRQ will be assigned to a PCI slot in your CMOS settings that conflicts with
existing equipment in your system. It’s important to verify that your CMOS settings for PCI do not exhibit
such conflicts if you are having problems installing your video capture card or if Plug and Play has trouble
detecting the card. Not all PCs have PCI slots that support bus-mastering. In such a case, the capture card
will have to be moved to another slot.

TROUBLESHOOTING AND ONLINE HELP RESOURCES
System Locking: Readjusting the Video Capture Card’s Memory Address
If your PCI video capture card installed correctly, yet your system locks up when attempting to access video
applications, there may be a Plug and Play memory overlap between your capture card and an existing video
card with a S3/968 chip set (Diamond Stealth 64 PCI, etc.). Determine whether your system has such a card
installed. If it does, follow these steps to alleviate the problem.
1. Click Windows 95 Start.
2. Point to Settings and click Control Panel.
3. Click the System icon.
4. Click the “Device Manager” tab.
5. Double-click Sound, video and game controllers.
6. Double-click U.S. Robotics Video Capture to bring up the “U.S. Robotics Video Capture” window.
7. Click Resources.
8. Uncheck the “Use Automatic Settings” box and double-click Memory Range.
9. In the box marked “Value”, change the address to 84000000-84000FFF. This range works for a wide
variety of configurations. If this range is not free or conflicts with another device, increase the original
memory range by 4 or decrease it by 8. (Remember: Add or subtract in hexadecimal!)
Example: 80000000-80000FFF (original) increased by 4 hex = 84000000-84000FFF

bit rate
Also referred to as transmission rate. The
number of binary digits, or bits, transmitted
per second (bps). Communications channels
using telephone channel modems are
established at set bit rates, commonly 2400,
4800, 9600, 14,400, 28,800 and higher.

characters per second (CPS)
byte
A data transfer rate generally estimated from
the bit rate and the character length. For
example, at 2400 bps, 8-bit characters with
start/stop bits (for a total of ten bits per
character) will be transmitted at a rate of
approximately 240 characters per second
(cps). Some protocols employ advanced
techniques, such as longer transmission frames
and data compression, to increase cps.
A group of binary digits stored and operated
upon as a unit. In user documentation, the
term usually refers to 8-bit units or
characters. One kilobyte (KB) is equal to
1,024 bytes or characters; 640 KB indicates
655,360 bytes or characters.
