3.1 Jumper Settings
This section tells how to set the jumpers to configure your card. For the locations of
each jumper, see the board layout diagram depicted earlier in this chapter. You con-
figure 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
cap (often protected by a plastic cover) that slides over the pins to connect them. To
"close" a jumper you connect the pins with the cap. To "open" a jumper you remove
the cap. Sometimes a jumper will have three pins, labeled 1, 2 and 3. In this case you
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 connections.
