C Glossary
ACK
A control character sent to acknowledge that a transmission block has
been received.
address
A unique designation for the location of data or the identity of a smart
device; allows each device on a single communications line to respond to
its own message.
AEL (Accessible Emission Limit)
The average power limitations of electronic radiation from a laser light
source as defined by the CDRH.
AIM
Automatic Identification Manufacturers, Inc.
alignment
The position of a scanning or detection device in relation to the target
scanning area or receiving element. Both the reader and photoeye require
proper alignment to assure optimal performance.
alphanumeric
Consisting of letters, numbers, and symbols.
ambient light
The lighting conditions in the scanning area. Ambient light can interfere
with successful scanning of bar codes.
ANSI (American National Standards Institute)
The principle standards development group in the U.S. A non-profit, non-
governmental group supported by over 1000 trade organizations,
professional societies, and companies. Member body to the ISO
(International Standards Organization).
aperture
Term used on the required CDRH warning labels to describe the laser exit
window.
application
A use to which something is put, or how it is used.
ASCII (American Standard Code for Information Interchange)
Pronounced
as-kee
. A standard seven bit plus parity code, representing
256 characters, established by ANSI to achieve compatibility between data
services.
aspect ratio
The ratio of height to width of a bar code symbol. A code twice as high as
wide would have an aspect ratio of 2; a code twice as wide as high would
have an aspect ratio of ½ or 0.5.
asynchronous transmission
Transmission in which the time intervals between transmitted characters
may be of unequal length. Transmission is controlled by start and stop bits
at the beginning and end of each character.
autodiscrimination (autodistinguish)
The ability of bar code reading equipment to recognize and correctly
decode more than one bar code symbology and process the data without
operator intervention. This is a prerequisite feature of linear bar code
scanners employed in open systems.
Axcess
The Windows®-based primary user interface that provides all the necessary
functions to set up, monitor, and diagnose the operations of an Axiom.
bar
The dark elements of a printed bar code symbol. Referred to as elements in
2D symbologies.
bar code
An array of rectangular bars/elements and spaces arranged in a predefined
pattern to represent elements of data referred to as characters.
bar code character
A single group of bars and spaces that represent an individual number,
letter, or other symbol.
bar code density
The number of characters that can be represented in a linear unit of
measure. Bar code density is often referred to in characters per inch (CPI).
bar code label
A label that carries a bar code and can be affixed to an article.
bar code reader, reader
A single device that performs two functions: 1. examines a printed spacial
pattern (bar code) and then, 2. decodes the encoded data.
bar code symbol
A group of bars that represent a character or group of characters whose
width and spacing is determined by a set of rules. In most cases, human
readable characters are printed below the bars.
bar height
The height of the shortest bar in a bar code.
bar length
The bar dimension perpendicular to the bar width.
bar width
The thickness of a bar measured from the edge closest to the symbol start
character to the trailing edge of the same bar.
baud rate
A unit used to measure communications speed or data transfer rate;
represents the number of discrete conditions or events per second.
BCC (Block Check Character)
Used to check transmission accuracy, a character transmitted by the
sender after each message block and compared with a block check
character computed by the receiver.
bed width
The width of the conveyor bed measured in inches (centimeters).
belt width
The width of the conveyor belt measured in inches.
bidirectional
A bar code symbol capable of being read successfully independent of
scanning direction.
bit (binary digit)
The contraction of binary digit, the smallest unit of information in the
binary system; a one or zero condition.
