P 300 STD/FZY/PRO Scanner Product Reference Guide
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.
COUNTRY FLAG In EAN-8 and EAN-13 codes, two or three digits which
appear immediately following the left guard bar pattern.
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. To
translate the bar/space pattern into defined characters within
a defined symbology.
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.
DISCRETE CODE A bar code or symbol in which the spaces between characters
(intercharacter gaps) are not part of the code (e.g., Code 39).
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.
EAN European Article Number. This European/International
version of the UPC provides its own coding format and
symbology standards. Element dimensions are specified
metrically. EAN is used primarily in retail. Main variants are
EAN-8 and EAN-13.
EDGE ROUGHNESS Edge irregularities as compared with a nominal bar edge.
ELEMENT Generic term for a bar or space.
