DIP Switch Settings
The top panel of NPort Express contains a table (shown below) de-
scribing DIP switch settings for the serial port.
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 for SW1, you must wait a few seconds
for the yellow Ready light to turn off and on, indicating that the
function of the serial port has been changed.
Switches SW2 and SW3 control the serial port’s Interface Mode.
(Note that RTS stands for Ready To Send and ADDC stands for
Automatic Data Detection 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
the MOXA PComm Terminal Emulator software, set SW1 to
ON, SW2 to OFF, and SW3 to OFF.
