CN1

This is the primary UART port and should be used for serial communication with
the card during initial evaluation. The pin out for the connector is managed by the
configuration of J2; it can support the following modes:

RS232 DTE

RS232 DCE

RS422/485 4-wire

RS422/485 2-wire

This header provides direct connections to the Airborne Device Server module
Ethernet connections. The output of this header is provided by the embedded
Ethernet PHY built in to the Airborne Device Server module. Please refer to the
WLNN DP500 data book for details of this output.

This header allow for the implementation of external magnetic or a capacitive
coupled circuit between the Evaluation board and a test system. The pin out for
the header can be seen in Table 7.
