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.
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.
An arrow is used on the motherboard to indicate the first pin of each jumper.
