Polarity; Ignore Unknown Characters - Motorola Symbol LS9208 Product Reference Manual

9 - 6 Symbol LS9208 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 could be attached,
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 a bar code below to select the polarity required by your decoder.

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.
When you select Do Not Send Bar Codes With Unknown Characters, bar codes containing at least one
unknown character are not sent to the host, and the scanner sounds an error beep.
