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
