Connecting pins 1 and 2 of a jumper configures the CAN physical layer to
be powered externally (from the bus cable power). In this configuration, the
power must be supplied on the V+ and V– pins on the port connector.
Connecting pins 2 and 3 of a jumper configures the CAN physical layer to
be powered internally (from the board). In this configuration, the V– signal
serves as the reference ground for the isolated signals.
