Connecting to the Dataport Command Interface through the
RS-232 port.
The RS-232 port
is a 9-pin, female, D-sub connector located on the back of the GW. The port
is configured as a DCE (Data Communications Equipment). The RS-232 port is default set to
9600 baud, 8 databits, none parity and 1 stopbit from factory. The RS-232 port is also referred
to as
the Dataport.

NOTE! A straight through cable should be used between the TANDBERG GW’s RS-232 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.
