Connector pin definitions
.
*These pins are reserved for future use by the VITA 42.6 XMC 10 Gigabit
Ethernet 4-lane Protocol Layer Standard.
X(2:3)_RD[0:3]. Link 2 and 3 Differential Receive.
These signals are used by
the XMC to receive high-speed protocol-specific data from the carrier over
Link 2 and 3. These signals tolerate EIA-644 signal levels.
X(2:3)_TD[0:3]. Link 2 and 3 Differential Transmit.
These signals are used by
the XMC to transmit high-speed protocol-specific data from the carrier over
Link 2 and 3. These signals tolerate EIA-644 signal levels.

Non-Isolation Considerations
The board is non-isolated, since there is electrical continuity between the
logic and field I/O grounds. As such, the field I/O connections are not
isolated from the system. Care should be taken in designing installations
without isolation to avoid noise pickup and ground loops caused by multiple
ground connections.
