Symbologies
Bar Width Status
If set to Mixed, the scanner will autodiscriminate between narrow bars and wide bars. If
set to All Narrow, all bars will be considered as narrow bars. If set to All Wide, all bars will
be considered as wide bars. If set to Fixed Threshold, it will use the fixed threshold value
to determine whether the bars are narrow or wide. The Bar Width Status setting will be
ignored when the scanner is able to tell the difference between the narrow and the wide bars.
Direction
Specifies the direction in which a symbol can be read.
Fixed Threshold Value

in pixels that will distinguish a narrow bar from a wide bar.
