3.
The CAN transceiver is not populated on the
phyCORE-LPC2292/94 and Jumpers J602 and J604 are closed;
CAN signals generated by the CAN transceiver (U2) on the Carrier
Board extend to connector P2A
with galvanic separation.
This
configuration requires connection of an external CAN supply
voltage of 7 to 13 V. The external power supply must be
only
connected to either P2A
or
P2B.
