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 represen-
tative before you make any changes.
Generally, you simply need a standard cable to make most
connections.
