2.5 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, connect the pins with the clip. To “open” a
jumper, 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.
The jumper settings are schematically depicted in this manual as
follows:
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.
