CCD camera AV40002.0 - Accu-Sort Systems - #101

An array of rectangular bars/elements and spaces arranged in a predefined pattern to represent elements of data referred to as characters.

A single group of bars and spaces that represent an individual number, letter, or other symbol.

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).

A label that carries a bar code and can be affixed to an article.

A single device that performs two functions: 1. examines a printed spacial pattern (bar code) and then, 2. decodes the encoded data.

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.

The height of the shortest bar in a bar code.

The bar dimension perpendicular to the 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.

A unit used to measure communications speed or data transfer rate; represents the number of discrete conditions or events per second.

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.

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.

The contraction of binary digit, the smallest unit of information in the binary system; a one or zero condition.

When the scanner is mounted under the conveyor to read codes on the bottom of the boxes or on the front or back of the boxes. If used there is not enough clearance for a standard front or back read.

Unit of data transmission rate. See baud rate.

A control character sent to acknowledge that a transmission block has been received.

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.

The average power limitations of electronic radiation from a laser light source as defined by the CDRH.

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.

Consisting of letters, numbers, and symbols.

The lighting conditions in the scanning area. Ambient light can interfere with successful scanning of bar codes.

The principle standards development group in the U.S. A non­profit, non-governmental group supported by over 1000 trade organizations, professional societies, and companies. Member body to the ISO (International Standards Organization).

Term used on the required CDRH warning labels to describe the laser exit window.

A use to which something is put, or how it is used.

Pronounced as-kee. A standard seven bit plus parity code, representing 256 characters, established by ANSI to achieve compatibility between data services.

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 % or 0.5.

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.

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.

The dark elements of a printed bar code symbol. Referred to as elements in 2D symbologies.
