4.6 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 NANO-HM651 is installed in the system, the jumpers must be set in
accordance with the desired configuration. The jumpers on the NANO-HM651 are listed in
6Table 4-1.
