5.7 Jumper settings

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.

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

jumpers. If you have any doubts about the best hardware configu-

ration for your application, contact your local distributor or sales

representatives before you make any changes.
