Jumpers
Configure the UNO-3272G to match the needs of your application by setting jumpers.
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 representative before you make any changes. Generally, you
simply need a standard cable to make most connections.
