The jumpers are used for internal texting only.
Explanation of Jumpers
To modify the operation of the backplane, jumpers
can be used to choose between optional settings.
Jumpers create shorts between two pins to
change the function of the connector. Pin 1 is
identied with a square solder pad on the printed
circuit board.
Note: On two pin jumpers, "Closed" means the
jumper is on and "Open" means the jumper is off
the pins.
