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 func-
tion of the connector. Pin 1 is identified
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.
