DIP Switch Settings and Explanation

how to set up the serial port using the three DIP switches located on
DE-311’s rear panel.

Switch SW1 controls the function of the serial port. Note that after
changing the setting of SW1, DE-311 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 and SW3 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:
!
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,
during which data is transmitted through DE-311’s Ethernet port. You
must set SW1 to the OFF position to establish a Telnet connection.
5. Software Installation Information
