24 | CHAPTER 3 – CONNECTING YOUR INTERACTIVE WHITEBOARD TO YOUR
COMPUTER
USB Extender Cables and Hubs
The 16' 5" (5 m) USB cable included with your interactive
whiteboard conforms to the USB 2.0 standard for
maximum length. If the included USB cable isn’t long
enough, use active USB extender cables, USB extenders
or hubs to extend the connection.
NOTES
•
Passive USB extension cables aren’t supported.
• Some computers use internal active hubs to provide more USB receptacles.
The computer’s 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 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 therefore won’t work with your interactive whiteboard.
