Symbol LS4278 Product Reference Guide GL-4
Codabar A discrete self-checking code with a character set
consisting of digits 0 to 9 and six additional characters: ( -
$ : / , +).
Code A set of unambiguous rules specifying the way in which
data may be represented as numbers and letters used to
represent information.
Code 11
A high density numeric symbology requiring a checksum for
calculation. The Code 11 character set consists of bar code
symbols representing the numbers 0-9, a dash symbol, the
start character, and the stop character.
Code 128 A high density symbology which allows the controller to
encode all 128 ASCII characters without adding extra
symbol elements.
Code 3 of 9 (Code 39) A versatile and widely used alphanumeric bar code
symbology with a set of 43 character types, including all
uppercase letters, numerals from 0 to 9, and 7 special
characters (- . / + % $ and space). The code name is derived
from the fact that 3 of 9 elements representing a character
are wide, while the remaining 6 are narrow.
Code 49 This symbol is a stack of 2 to 8 rows. Each row encodes row
count information plus data characters. For more
information, go to the AIM web site or the ANSI web site
(see
Stacked Symbol (2D Symbols) ).
Code 93 An industrial symbology compatible with Code 39 but
offering a full character ASCII set and a higher coding
density than Code 39.
Code Length Number of data characters in a bar code between the start
and stop characters, not including those characters.
Codeword As a symbol character value, this is an intermediate level of
coding between source data and the graphical encodation
in the symbol.
Concatenation The construction of a string of data from two or more
strings by appending each string in succession. The linking
or chaining together of separate items of data in a bar code
symbol or of the data contained in two or more separate bar
code symbols (also referred to as message append and
structured append).
Continuous Code A bar code or symbol in which all spaces within the symbol
are parts of characters. There are no intercharacter gaps in
a continuous code. The absence of gaps allows for greater
information density.
Contrast The difference in reflectance between the black and white
(or bar and space) areas of a symbol.
Data Identifier A specified character or string of characters that defines
the intended use of the data element that follows. For the
purposes of automatic data capture technologies, data
identifier refers to the alphanumeric identifiers as defined
in ANSI MH10.8.2, formerly known as ANSI/FACT data
identifiers.
