Chapter 2: Jumpers and Connectors
Jumper Settings
A jumper is the simplest kind of electric switch. It consists of two metal
pins and a cap. When setting the jumpers, ensure that the jumper caps are
placed on the correct pins. When the jumper cap is placed on both pins,
the jumper is
short
. If you remove the jumper cap, or place the jumper
cap on just one pin, the jumper is
open
.
Refer to the illustrations below for examples of what the 2-pin and 3-pin
jumpers look like when they are short (on) and open (off).
Two-Pin Jumpers: Open (Left) and Short (Right)
Three-Pin Jumpers: Pins 1 and 2 Are Short
