The top panel of NPort Express contains the following table, which
describes how to set up the serial port using the four DIP switches located

Switch SW1 controls the function of the serial port (ON, or up, for RS-232
Console connection, and down for Data Communication, such as when
NPort Express is connected to your serial device). Note that after
changing the setting of SW1, NPort Express will reboot to initialize the
new setting. You must wait a few seconds for the green Ready light to
blink off and then on again, indicating that the function of the serial port
has been changed.
Switches SW2, SW3, and SW4 control the serial port's data
communication Interface Mode. (Note that RTS stands for Ready To Send
and ADDC stands for Automatic Data Direction Control.)
Keep the following points in mind when setting the DIP switches.
RS-232 Console
To use the serial port as a console connection, such as when using MOXA
PComm Terminal Emulator or HyperTerminal, set SW1 to the ON position.
Telnet Connection
Some setup procedures can be carried out through a Telnet connection,
during which data is transmitted through NPort Express's Ethernet port.
However, you must set SW1 to the OFF position to establish a Telnet
connection.
