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.

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.
