Trackball Mode -
The KE-USB36FS auxiliary interface connector
can accept optical signals from a device such as a Spinner or
a Trackball. Power
is supplied to the
trackball interface
from
the
KE-
USB36FS for 5 volt
operation
only.
This interface is
compatible with the
most popular active or passive Trackballs and Spinners.
The Trackball header mates with the Hagstrom Electronics KE-
