Wasp Bar Code WLS 8400 ER Encoded Area, Error Correction, Error Detection, Error-Correction Level

GL-8WLS 8400 Product Reference Guide

Encoded Area	Total linear dimension occupied by all characters of a
	code pattern, including start/stop characters and data.
Error Correction	A reader or decoder's use of mathematical schemes to
	reconstruct or replace damaged or missing symbol
	characters to enable the reading of the symbol data.
Error Detection	This occurs when error-correction characters detect
	that the presence of errors in the symbol exceeds the
	error correction capacity, and keeps the symbol from
	being decoded as erroneous data.
Error-Correction Characters	Symbol characters used for error correction and
	detection, calculated automatically from the other
	symbol characters.
Error-Correction Level	An indicator of the number of characters used in a
	symbology for error correction. A higher level of
	error correction allows for correcting greater
	potential symbol damage.
Error-Detection Characters	Symbol characters reserved for error detection that
	are calculated automatically from the other symbol
	characters.
Fixed Beam Bar Code Reader	A scanning device where scanning motion is
	achieved by moving the object relative to the reader;
	as opposed to a moving beam reader.
Guard Bars	Bars located at both ends and the center of a UPC and
	EAN symbol to provide reference points for
	scanning.
Horizontal Bar Code	A bar code or symbol with an overall length
	dimension that is parallel to the horizon, which
	resembles a picket fence.
Host Computer	A computer that serves other terminals in a network,
	providing such services as computation, database
	access, supervisory programs, and network control.
IEC	International Electrotechnical Commission. This
	international agency regulates laser safety by
	specifying various laser operation classes based on
	power output during operation.
