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.

1.8.2 CMOS clear (CMOS1)

The PCE-7210 single board computer contains a jumper that can erase

CMOS data and reset the system BIOS information. Normally this

jumper should be set with pins 1-2 closed. If you want to reset the CMOS

data, set CMOS1 to 2-3 closed for just a few seconds, and then move the

jumper back to 1-2 closed. This procedure will reset the CMOS to its

default setting.
