Symbologies
Fixed Symbol Length Status
When enabled, the reader will check the symbol length against the symbol length field. If
disabled, any length will be considered valid.
Symbol Length
Specifies the exact number of bars that must be present for the reader to recognize and
decode the Pharmacode symbol.
Minimum Bars
Sets the minimum number of bars that a Pharmacode symbol must have to be considered
valid.
Bar Width Status
If set to Mixed, the reader 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 reader 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
Used when Bar Width Status is set to Fixed Threshold. Defines the minimum difference
in pixels that will distinguish a narrow bar from a wide bar.
