Connecting to the Data port Command Interface through the
RS-232 port.
The RS-232 port is a 9-pin, female, D-sub connector located on the front of the GW. The port
is configured as a DCE (Data Communications Equipment). The RS-232 port is default set to
115200 baud, 8 data bits, none parity and 1 stop bit from factory. The RS-232 port is also
referred to as the Data port.

and the DTE.
The figure below illustrates the recommended cable-wiring scheme for connecting the GW to
a PC through RS-232.
DTR and RTS are ignored. DSR, CD, and CTS are always asserted, while RI is not used.
