Note:
A jumper consists of two or more pins mounted on the board. When a jumper cap is placed over two pins, it is
designated as IN. When there are more than two pins on the jumper, the pins to be shorted are indicated as 1-2 (to
short pin 1 to pin 2), 2-3 (to short pin 2 to pin 3), etc. When no jumper cap is to be placed on the jumper, it is
designated as OPEN or OUT.
