3.
The CAN transceiver is not populating the phyCORE-LPC2292/94
and Jumpers J603 and J605 are closed; CAN signals generated by
the CAN transceiver (U3) on the Carrier Board extend to connector
P2B
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.
