When On-Line Operating mode is used, the scanner is activated by a presence sensor when
the object enters its reading zone.
The data is also transmitted on the Auxiliary interface (if configured for Standard
communication mode), as well as on the Main interface. The auxiliary interface uses RS232
for this layout.
Host Mode programming can be accomplished either through the Main or the Auxiliary
interface.
