3. Hardware Introduction
The NPort DE-211 device server has one female DB25 serial port. The
four DIP switches located on the rear panel are used to select between
RS-232 COM mode, and one of four data modes: RS-232, RS-422,
4-wire RS-485, and 2-wire RS-485. See the “DIP Switch Settings &
Explanation” section for details.

Switch SW1 controls the function of the serial port. Note that after
changing the setting of SW1, DE-211 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. (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:
y
To use the serial port as an RS-232 console connection, such as when
using MOXA PComm Terminal Emulator or HyperTerminal, set SW1
to the ON position
y
Some setup procedures can be carried out through a Telnet connection,
in which case data is transmitted through DE-211’s Ethernet port.
However, you must set SW1 to the OFF position to establish a Telnet
connection.
