Ethernet Wire Cabling Interface
The Ethernet wire cabling interface is implemented using up to two 8-contact, female, RJ45
connectors. CON1 is implemented as Channel A when installed, and CON5 is implemented as
Channel B when installed. As the Gigabit Ethernet controller is able to automatically detect the

cabling configuration and Ethernet standard in use, the
pinout of the individual connectors is a function of the im-
plementation.
The following figure and table indicate the pin assignment
and signal function for each connector as a function of the
implementation.
The signal pinouts on the left side of the table are for the
standard Media Dependent Interface (MDI) using appro-
priate CAT5 UTP cabling for the Ethernet standard in use.
The signal pinouts on the right side of the table are for the
Media Dependent Interface Crossed (MDIX) using appro-
priate CAT5 UTP cabling for the Ethernet standard in use.
In addition, the input / output status of each signal is also
indicated in the table.
