Explanation of Jumpers
EC22 R227
To modify the operation of the backplane,
GND GND
jumpers can be used to choose between +12V +5V
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.
