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 computer'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
The illustrations on the

jumper. 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.

These illustrations show
