USB Hubs
A USB hub may plug into an existing USB port which will expand the port from a
single USB connection to as many as four connections. If using Tracker Pro with a
USB hub, you must ensure that the hub is externally (self) powered.
Using Alternate Clicking Devices
Tracker Pro may be used with any clicking device. For those clients with
extremely limited mobility you may want to consider either WISP 2000, Madentec’s
wireless integrated switch platform or Magic Cursor 2000, an on-screen dwell
program. Information about WISP 2000 and Magic Cursor 2000 is available on our
web site at www.madentec.com.
You may also want to use some form of ability switch such as a Jelly Bean™, from
AbleNet. When using an alternate switch, plug the stereo adapter provided into
the integrated switch jack on the USB cable of Tracker Pro. An alternate switch or
switches may then be plugged into the connections on the stereo adapter. The
stereo adapter will allow for left and right clicking ability.
See Illustration E.
Note Please use the stereo adapter even if you only require one switch. This will
properly convert the stereo output of both left and right mouse button functions
to the single switch used on
Macintosh.
