SW1 is used to activate the serial console. When SW1 has been
changed, the unit will reboot to initialize the new setting. You w il l
need to wait for the green Ready LED to tur n off and th en on again ,
which indicates that serial console mode has been activated or
deactivated. SW2 and SW3 are used to select the serial port
interface. (Note that RTS stands for Ready To Send and ADDC
stands for Automatic Data Direction Control.)

When adjustin g the DIP switches, p le a s e keep the following in
mind:

• 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.

• Some configuration may be carried out through a Telnet
connection, du ring which da ta is transmi tted throug h the unit’s
Ethernet port. SW1 must be OFF in order for the unit to
establish a Telnet connection.
