2.4 Setting jumpers
You may configure your card to match the needs of your application
by setting jumpers. 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 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.
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 connec-
tions.
