Setting Jumpers

You may configure your card to match the needs of your application by setting jump-

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,

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

simply need a standard cable to make most connections.
