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
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
and Explanation" section for details.

In addition to placing
the DE-211 unit on a
desktop or other
horizontal surface, you
may also make use of
the DIN-Rail or Wall
Mount options, as
illustrated here.
DIP Switch Settings and Explanation
The top panel of the DE-211 contains the following table, which
describes how to set up the serial port using the four DIP switches
located on DE-211's rear panel.
Serial SW2 SW3 SW4 Serial Interface Mode
SW1
Connection OFF OFF OFF RS-232
RS-232 OFF ON ON RS-422
ON
Console ON OFF ON 4-wire RS-485 by RTS
ON ON ON 4-wire RS-485 by ADDC
OFF Data Comm ON OFF OFF 2-wire RS-485 by RTS
ON ON OFF 2-wire RS-485 by ADDC
Switch SW1 controls the function of the serial port. Note that after
changing the setting of SW1, the 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:
• 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.
• Some setup procedures can be carried out through a Telnet
connection, in which case data is transmitted through the
DE-211's Ethernet port. However, you must set SW1 to the
OFF position to establish a Telnet connection.
