Chapter 4 Jumper Settings and Connectors

4.1.1.3 Jumper Description

Cards can be configured 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 representative before you make any changes.
