2-3 Front Jumper Locations and Settings

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.
