2.3.3.2
Ethernet Interface
The EBC2 SAI provides two Fast Ethernet interfaces: FE1 and FE2.
For monitoring and control purposes, LED functionality is provided to indicate activity, link, and
speed status information for the respective interfaces.
2.3.3.3
CAN Interface
The EBC2 SAI provides two Controller Area Network (CAN) interfaces. Defaultwise, CAN TXD/
RXD0 is implemented on the EBC2. If CAN TXD/RXD1 is required, it must be specified when
ordering the EBC2. In addition, the default configuration for this interface is with opto-isolation.
If non-opto-isolation is required, it also must be specified when ordering.
The following table provides a summary of the CAN signals implemented on the Communica-
tions Interface connector.
