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 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 doubt about the best hardware configuration for
your applications, contact your local distributor or sales represen-
tative before you make any change.
Generally, you simply need a standard cable to make most connec-
tions.
