Provided below is an example schematic using MAX3232, the from Texas Instruments
RS-232 Line Driver/Receiver
(TI), to make a console board.
(Datasheet of the MAX3232 can be found on TI web site at http://focus.ti.com/lit/ds/symlink/max3232.pdf)
The DB9 (Male) connector is wired as a DCE (think of this as a peripheral serial port), and can be connected
directly to the serial port on a host PC. This gives you access to the built-in serial console on the router (using the
protocol of 38400bps, 8 data bits, none parity, 1 stop bit, without flow control).
Connect the console board to the pin header (J303) on the router board.
