2-4 Jumpers
Explanation of Jumpers
To modify the operation of the add-on card, a
jumper can be used to choose between optional
settings. A jumper creates 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. See the add-on card layout
on Page 2-1 for the jumper location.
Note:
On two pin jumpers, "Closed"
means the jumper is on and "Open"
means the jumper is off the pins.
