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.
Scan the appropriate bar code below to select the polarity required by your decoder.
