1.7 Setting Jumpers

You configure 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 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.

Open C ed Closed 2-3los

OFF ON ON 2-3

A pair of nee

dle-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 change. Generally, you

simply need a standard cable to make most connections.
