3. Jumpers

This section will explain how to configure the VIA VB7009 to match the needs of your application by
setting the jumpers.
Jumper Description
A jumper consists of pair conductive pins used to close in or bypass an electronic circuit to set up or
configure particular feature using a jumper cap. The jumper cap is a small metal clip covered by plastic. It
performs like a connecting bridge to short (connect) the pair of pins. The usual colors of the jumper cap
are black/red/blue/white/yellow.
Jumper Setting
There are two settings of the jumper pin: "Short and Open". The pins are "Short" when a jumper cap is
placed on the pair of pins. The pins are "Open" if the jumper cap is removed.
In addition, there are jumpers that have three or more pins, and some pins are arranged in series. In case
of a jumper with three pins, place the jumper cap on pin 1 and pin 2 or pin 2 and 3 to Short it.
Some jumpers size are small or mounted on the crowded location of the board that makes it difficult to
access. Therefore, using a long-nose plier in installing and removing the jumper cap is very helpful.

Caution:
Make sure to install the jumper cap on the correct pins. Installing it in the wrong pin might cause damage and
malfunction.
