Serial Port
The Cisco standard High Speed Smart Serial 12-in-1 connector allows the highest flexibility of
connections to various DTE/DCE devices. The 12-in-1 serial interface pins connect to the FPGA. The
FPGA configures the pin directions based on the cable type used.
Figure 1-6 shows the magnified view
of the 12-in-1 serial port. For more information, see About Serial Connections.
