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 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.
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.
CTS Clear to send.
Dead Zone An area within a scanner's field of view, in which specular reflection may
prevent a successful decode.
Decode To recognize a bar code symbology (e.g., UPC/EAN) and then analyze the
content of the specific bar code scanned.
Decode Algorithm A decoding scheme that converts pulse widths into data representation of
the letters or numbers encoded within a bar code symbol.
Depth of Field The range between minimum and maximum distances at which a scanner
can read a symbol with a certain minimum element width.
Digitized Bar
Pattern (DBP) A digital representation of a decoded bar code.
Discrete 2 of 5 A binary bar code symbology representing each character by a group of
five bars, two of which are wide. The location of wide bars in the group
determines which character is encoded; spaces are insignificant. Only
numeric characters (0 to 9) and START/STOP characters may be
encoded.
Discrete Code A bar code or symbol in which the spaces between characters
(intercharacter gaps) are not part of the code.
