CAUTION
The two Ethernet ports share a common ground (transformer center tap),
that is floating until you determine how the common ground is
connected. The grounding holes (8) of the LittleBoard 700 are connected
to ground potential (return) of the DC power supply connected to the
board through J10.
NOTE
Pin 1 is shown as a black square in all connectors and jumpers in all
illustrations.
