Glossary - 3
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.
D
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.
Decryption.
Decryption is the decoding and unscrambling of received encrypted data. Also see,
Encryption
and
Key
.
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 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.
DRAM.
Dynamic random access memory.
E
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.
Element.
Generic term for a bar or space.
Encoded Area.
Total linear dimension occupied by all characters of a code pattern, including start/stop characters and data.
ENQ (RS-232).
ENQ software handshaking is also supported for the data sent to the host.
ESD.
Electro-Static Discharge
F
Flash Memory.
Flash memory is responsible for storing the system firmware and is non-volatile. If the system power is
interrupted the data is not lost.
