Polarity
Scan a bar code below to select the polarity required by the decoder. 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 expect 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.
