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.
