Serial UART ports
The development board supports the four serial ports available on the NS9210
Processor Module.
Serial port D,
RS232 The serial (UART) port D connector, X3, is a DSUB9 male connector and is also used as
the standard console. This asynchronous serial port is DTE and requires a null-modem
cable to connect to a computer serial port.
The serial port D interface corresponds to NS9215 UART port D. The line driver is
enabled or disabled using the jumper J1.
