Set Lengths for MSI (continued)
NOTE Due to the construction of the MSI symbology, it is possible for a scan line covering only a portion of the
code to be interpreted as a complete scan, yielding less data than is encoded in the bar code. To prevent
this, select specific lengths (MSI - One Discrete Length - Two Discrete Lengths) for MSI applications.
MSI - One Discrete Length
MSI - Two Discrete Lengths
MSI - Length Within Range
MSI - Any Length
