Appendix D:
Trackball/Spinner Interface
The KE-USB108 features an eight position interface connector
which accepts optical signals from a device such as a Trackball.
The unit also features a four position interface connector which
accepts signals from a device such as a Spinner.
Power is supplied to both the spinner and trackball interface
from the KE-USB108 for 5 volt operation only. This interface is
compatible with most popular active high or low Trackballs and
Spinners currently on the market.
Note: See sections "Trackball Control" and "Spinner Control" in
the manual for active high or low jumper settings.
Use our KE-TBH3 cable to connect from the KE-USB108 directly
to a Trackball or use our KE-SP3 cable to connect from the
KE-USB108 directly to a Spinner.
Use the diagram below to make a connecting cable for a Spinner
and/or Trackball.
