NOTE:
These jumper settings and the jumper locations are described in detail
in the user manual that came with the POS-9455 motherboard. Please
refer to the manual for more detailed descriptions of the jumper
settings.
NOTE:
A jumper is a metal bridge that is used to close an electrical circuit. 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/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.
The POS-9455 comes with some jumpers as listed in Table 4-1.
