4.2 PACKTRACK™

PackTrack™ is a patented operating mode for Datalogic Omni-Directional Reading Stations
used to read and correctly assign codes read on different packs when placed in the scanner
Reading Area at the same time.
In fact, in the following example, the codes of two or more consecutive packs are found at
the same time in the scanner reading area. Therefore, the condition occurs where, in the
sequence of the two packs, the code of the second pack is read first, just before the code of
the previous pack. A system without PackTrack™ would assign the code of the second pack
to first pack and vice versa, thus causing a gross error in sortation.
Working in PackTrack™ mode requires the presence of an encoder and a presence sensor
to track the moving packs.
All PackTrack™ functionalities are programmed via the Genius™ tool (refer to the Genius™
Help On-Line for details).
