Jumper settings

This section tells how to set the jumpers to configure your card. It

gives the card default configuration and your options for each jumper.

How to set jumpers

You configure your card 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 pins 1 and 2 or 2 and 3.

You may find pair of needle-nose pliers useful for setting the jumpers.

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.

Default Settings

The board is shipped with default settings. If you need to change

these settings, however, see the following sections. Otherwise, you can
