Polarity
Polarity determines how the scanner's wand emulation interface creates the Digitized
Barcode Pattern (DBP). DBP is a digital signal that represents the scanned bar code.
Different decoders, to which this device could be attached, are expecting the DBP to be in
a certain format. The DBP either has the "highs" represent bars and the "lows" represent
spaces (margins), or the "highs" represent spaces (margins) and the "lows" represent bars.
