1.8 Jumper Settings

This section provides instructions on how to configure your single board

computer by setting the jumpers. It also includes the single board com-

puter's default settings and your options for each jumper.

1.8.1 How to set jumpers

You can configure your single board computer to match the needs of your

application by setting the jumpers. A jumper is a metal bridge that closes

an electrical circuit. It consists of two metal pins and a small metal clip

(often protected by a plastic cover) that slides over the pins to connect

them. To “close” (or turn ON) a jumper, you connect the pins with the

clip. To “open” (or turn OFF) a jumper, you remove the clip. Sometimes a

jumper consists of a set of three pins, labeled 1, 2, and 3. In this case you

connect either pins 1 and 2, or 2 and 3. A pair of needle-nose pliers may

be useful when setting jumpers.

Table 1.3: How to Set Jumpers

pins, the jumper is

SHORT. If you remove

the jumper cap, or place

the jumper cap on just

one pin, the jumper is

OPEN.

Open (off)

Short (on)

These illustrations show

a 3-pin jumper. Pins 1
