The jumper is a small terminal used for connecting or
disconnecting a circuit. The jumper is on when the plug
covers both wires of the terminal. Jumper settings can be
changed by either attaching or removing the rectangular
jumper plug. If the jumper is to be turned off, connect it to
just one of the two terminal pins. By doing this, you can
avoid losing the unused jumper plug.
