2.3 Jumper and Connector List

You can configure your board to match the needs of your application by setting jumpers. A

jumper is the simplest kind of electric switch.

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” a jumper you connect the pins with the clip.

To “open” a jumper you remove the clip. Sometimes a jumper will have three pins, labeled 1,

2, and 3. In this case, you would connect either two pins.

The jumper settings are schematically depicted in this manual as follows:

A pair of needle-nose pliers may be helpful when working with jumpers.

Connectors on the board are linked to external devices such as hard disk drives, a

keyboard, or floppy drives. In addition, the board has a number of jumpers that allow you to

configure your system to suit your application.

If you have any doubts about the best hardware configuration for your application, contact

your local distributor or sales representative before you make any changes.

The following tables list the function of each of the board’s jumpers and connectors.
