the existing (empty) terminal connectors from the Personality
board to allow for the Expansion board terminal connector. You
can place the (empty) connector onto the available COM port on
the Expansion board.

Remove this terminal connector
and connect it to an available COM
port on the IntelliTouch Personality
board or EasyTouch motherboard
