3.5 Setting Jumpers

You may

configure

your

panel PC to match the needs of

your

application

by setting jumpers. A jumper

a metal

bridge

used

to close an

electric cir- cuit. 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

open closed closed 2-3

The jumper settings

are

schematically depicted in this

manual

as follows:.

open closed closed 2-3

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.

Generally, you simply

need

a standard cable

to make most

connections.
