The auxiliary serial interface of the slave scanners can be used in Local Echo
communication 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.
