Serial Line Communication
Connect the serial interface by using either the User Port or the Service
Port.
For permanent interfacing to host system, use the User Port. You can
change the serial settings and operate in RUN, STOP, SEND, POLL, and
MODBUS modes.
For temporary connections, use the Service Port. The Service Port is
always available with fixed serial settings.
