are debounced for that purpose. Logic drivers may be attached
to the inputs as well, provided they are an active low, logic level
signal. Refer to Appendix A on specifications for the timing of
logic signals.
The KE-USB108 input headers are dual row headers with .100"
spaced pins. This format is suitable for many readily available
connectors on the market, including a typical IDE hard drive cable.
Since all the inputs are activated by the same logic Ground, this
Ground may be "daisy chained" to the Ground of all of the input
switches.
We also offer a breakout board for screw terminal access to the
KE-USB108 input headers (our part number IOX36). This interface
board attaches to the KE-USB108 headers through an IDE cable
(provided with the IOX36).
manual for details on the IOX36.
Trackball Header:
The KE-USB108 features an Input Header for connection
to a Trackball. We offer a Trackball Cable (our part number
KE-TBH3) to connect the KE-USB108 trackball input to the trackball
itself. See the Accessories page of this manual for details on the
KE-TBH3.
NOTE: Do not supply power to the trackball interface connector.
NOTE: Never attach external power to the Inputs.
