9 - 6 Symbol LS2208 Product Reference Guide 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 can connect, are expecting the DBP 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 the decoder requires. *Bar High/Margin Low Bar Low/Margin High Ignore Unknown Characters Unknown characters are characters the host does not recognize. Select Send Bar Codes With Unknown Characters to send all bar code data except for unknown characters. The scanner sounds no error beeps. Select Do Not Send Bar Codes With Unknown Characters to prevent sending bar codes containing at least one unknown character to the host. The scanner sounds an error beep. *Send Bar Codes With Unknown Characters (Transmit) Do Not Send Bar Codes With Unknown Characters (Do Not Transmit)
