2.6 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 s
lides 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 change.
Generally, you simply need a standard cable to make most
connections.
