Wand Emulation Interface 9 - 5Leading Margin (Quiet Zone)Scan a bar code below to select a leading margin duration. A leading margin is the time that precedes the first barof the scan, in milliseconds. The minimum allowed value is 80 msec and the maximum is 250 msec. Use thisparameter to accommodate older wand decoders that cannot handle short leading margins.NOTE250 msec is the maximum value that this parameter can attain, however, 200 msec is sufficient.*80 msec140 msec200 msecPolarityPolarity determines how the scanner's Wand Emulation interface creates the Digitized Bar code Pattern (DBP).DBP is a digital signal that represents the scanned bar code. Different decoders, to which this device can connect,expect 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 LowBar Low/Margin High
