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 SHORT. 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.
