Clear to send.
An area within a scanner's fi eld of view, in which specular refl ection
may prevent a successful decode.
To recognize a bar code symbology (e.g., UPC/EAN) and then
analyze the content of the specifi c bar code scanned.
A decoding scheme that converts pulse widths into data
representation of the letters or numbers encoded within a bar code
symbol.
The range between minimum and maximum distances at which a
scanner can read a symbol with a certain minimum element width.
A digital representation of a decoded bar code.
A binary bar code symbology representing each character by a
group of fi ve bars, two of which are wide. The location of wide bars
in the group determines which character is encoded; spaces are
insignifi cant. Only numeric characters (0 to 9) and START/STOP
characters may be encoded.
A bar code or symbol in which the spaces between characters
(intercharacter gaps) are not part of the code.
European Article Number. This European/International version of
the UPC provides its own coding format and symbology standards.
Element dimensions are specifi ed metrically. EAN is used primarily
in retail.
Generic term for a bar or space.
Total linear dimension occupied by all characters of a code pattern,
including start/stop characters and data.
A computer that serves other terminals in a network, providing
such services as computation, database access, supervisory
programs, and network control.
International Electrotechnical Commission. This international
agency regulates laser safety by specifying various laser operation
classes based on power output during operation.
This is the lowest power IEC laser classifi cation. IEC Class I devices
are safe under reasonably foreseeable conditions of operation.
Software and other controls to limit exposure to laser light may be
required to achieve IEC Class 1 operation. The IEC time base for
Class 1 devices is 100 seconds if intentional viewing of laser light is
not required in the design or function of the device. The IEC time
