The auxiliary serial interface can be used in Local Echo mode to control any single
scanner (visualize collected data) or to configure it using the WinHost utility or Host
Mode programming procedure.
When On-Line Operating mode is used, the scanner is activated by an External
Trigger (photoelectric sensor) when the object enters its reading zone.
