2.4 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, 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 representa-

tive before you make any changes.

Generally, you simply need a standard cable to make most connec-

tions.
