4-wire RS-485, and 2-wire RS-485. See the “DIP Switch Settings
and Explanation” section for details.

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.
