4.3 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.
Before the WAFER-US15WP is installed in the system, the jumpers must be set in
accordance with the desired configuration. The jumpers on the WAFER-US15WP are
listed in Table 4-1.
