2-7 Jumper Settings
Explanation of Jumpers
To modify the operation of the mother-
board, 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 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.
