5.1.1Setting jumpers

The Panel PC can be configured to match the needs of each application by setting the 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), which slides over the pins to close the circuit and connect them. To “close” a jumper, connect the pins with the clip. To “open” a jumper, remove the clip. Sometimes a jumper has three pins, labeled 1, 2, and 3. In this case, it is possible to connect either pins 1 and 2 or pins 2 and 3 to each other.

Open Closed Closed 2 - 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 there are any doubts about the best hardware configuration for a particular application, contact the local distributor or sales representative before making any changes.

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