2.3 Setting jumpers
You may configure your card to match the needs of your application by setting jump-
ers. A jumper is the simplest kind of electrical switch. It consists of two metal pins and
a small metal clip (often protected by a plastic cover) that slides over the pins to con-
nect 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.
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.
