4.1 Jumpers and Connectors
4.1.1 Setting jumpers
You can configure your panel PC to match the needs of your application 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 pins 2 and
3.

The jumper settings are schematically depicted in this manual as follows:.
open closed closed 2-3
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.
