Wand Emulation Interface 9-7
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.
Ignore Unknown Characters
Unknown characters are characters the host does not recognize. When Send Bar Codes With Unknown Characters is selected,
all bar code data is sent except for unknown characters, and no error beeps sound on the scanner. When Do Not Send Bar Codes
With Unknown Characters is selected, bar codes containing at least one unknown character are not sent to the host, and the
scanner emits an error beep.
