5.1 Jumpers and Connectors

This chapter supplies more detailed information about the internal jumper settings

and an outline of the I/O ports available on the PPC-L158T.

5.1.1 Setting Jumpers

The Panel PC can be configured to match the needs of each 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), 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.
