4.5 Jumper Settings

NOTE:

A jumper is a metal bridge used to close an

electrical circuit. It consists of two or three

metal pins and a small metal clip (often

protected by a plastic cover) that slides over

the pins to connect them. To CLOSE/SHORT

a jumper means connecting the pins of the

jumper with the plastic clip and to OPEN a

jumper means removing the plastic clip from a

jumper.

Before the PICOe-PV-D4251/N4551/D5251 is installed in the system, the jumpers must

be set in accordance with the desired configuration. The jumpers on the

PICOe-PV-D4251/N4551/D5251 are listed in
