Setting 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.

Open Closed Closed 2-3

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

Generally, you simply need a standard cable to make most connections.
