UART Interface
Serial Port 2, RS232, X27
The serial (UART) port 2 connector, X27, is a DB-9 male connector, which is also used as the
standard console port. This asynchronous serial port is operating in DTE mode and requires a
null-modem cable to connect to a computer serial port.
The serial port 2 interface is connected to i.MX51 UART port 2. The corresponding line driver
on the development board can be enabled or disabled using switch S7. Refer to paragraph
"Switches and Push-buttons" in this document for more information.
