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 800 are
connected to ground potential (return) of the DC power supply
connected to the board through J19.
NOTE Pin-1 is shown as a black pin (square or round) in all connectors and
jumpers in all illustrations.
