The RS-232 console connector is used for accessing the console of the uCLinux kernel running on the ADSP-BF548 processor. It uses the ADM3202 RS-232 line driver and receiver to connect to UART1 of the ADSP-BF548. The RS-232 signals connect to a DB-9 connector, J4. A circuit implementation of the RS-232 console is shown below.
