You may configure your card to match the needs of your applica-
tion by setting jumpers. A jumper is a metal bridge used to close an
electric circuit. 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 representa-
tive before you make any changes.
Generally, you simply need a standard cable to make most connec-
tions.
