Setting jumpers
You may configure your card to match the needs of your applica-
tion 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 representa-
tive before you make any changes.
Generally, you simply need a standard cable to make most connec-
tions.
