4.5 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, connect the pins with the clip. To
"open” a jumper, remove the clip. Sometimes a jumper will have
three pins, labeled 1, 2, and 3. In this case, connect either pins 1
and 2 or 2 and 3.
Open Closed Closed 2-3
The jumper settings are schematically depicted in this manual as
follows:
Open Closed Closed 2-3
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, a standard cable is all that is needed to make most
connections.
