2.7 Jumpers Setup
The illustration shows how jumpers are
setup. When the jumper cap is placed on
pins, the jumper is “SHORT”. If no jumper
cap is placed on the pins, the jumper is
“OPEN”. The illustration shows a 3-pin
jumper whose pin1 and pin2 are “SHORT”
when jumper cap is placed on these 2 pins.
