Configuring Your Computer Settings - SMART Board SB640 Installation And User Manual

Chapter 3
Connecting your interactive whiteboard to your computer
NOTES
Passive USB extension cables aren't supported.
l
Some computers use internal active hubs to provide more USB receptacles. The computer's
l
operating system might recognize these internal hubs as external devices, limiting the number of
USB extenders that you can use.
Alternatively, USB extenders with Cat 5 cabling enable you to extend your cable to approximately 325'
(100 m).
NOTE
When you use these units, your cables and connectors must meet the vendor's specifications.
Impedance mismatches and poor connections can cause signal degradation and performance problems
with your interactive whiteboard.
A USB hub should also work well with your interactive whiteboard. If you also use streaming audio through
the USB hub, ensure that the Microsoft USB drivers are up-to-date so that your interactive whiteboard's
performance doesn't become choppy, intermittent or otherwise unacceptable.
IMPORTANT
If you use a USB extender or hub with your interactive whiteboard, it must comply with USB 1.1 or
l
USB 2.0 interfaces to work correctly. It must also provide at least 300 mA to your interactive
whiteboard.
Some self-powered extenders and hubs provide only up to 100 mA to a connected device and
l
therefore won't work with your interactive whiteboard.
