2.1.3 Setting Jumpers

You may configure your card to match the needs of your application by
setting jumpers. A jumper is a metal bridge used to close an electric cir-
cuit. 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.
