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 1-6shows the magnified view of the 12-in-1 serial port. For more information, see About Serial Connections.
