RS232/485 Port
There is a simple serial port that supports both RS232 and RS485 modes. The port
operates through two signal terminals. In the RS232 mode, these are RX and TX, in
the RS485 mode -- RX/TX+ and RX/TX-. There is no provision for flow control (RTS
and CTS lines are not present), or RS422 interface.
The serial port can be used, for instance, to connect to another IB100x board. In
the RS232 mode, the serial port can also be used to update the firmware of the
EM1000 module located on the NB10x0 board.
Serial port lines
Serial port lines are on terminal block 1:
