, which provides a
panel-mount RJ-45 jack for connection to standard CAT5 network cables.
J10, which may be used instead of J11, provides an on-board RJ45. For development, J10
may be more useful, but it is anticipated that most embedded applications will make the
J11 connection more useful (for panel-mount network connection).
Ensure that only one connection or the other (J11 or J10) is used; both connectors are
NOT independent and neither will function if they are both attached.
