GLOSSARY
ACR™
Advanced Code Reconstruction technology allows the reading of low aspect ratio labels
placed anywhere on a parcel and enhances the readability of poorly printed or damaged
codes.
Aperture
Term used on the required CDRH warning labels to describe the laser exit window.
ASTRA™
Automatically Switched Reading Area™ is a Datalogic technology based on a multi-laser
architecture and a fixed mounted optic system which concentrates the multiple laser
emissions in a single laser beam. As each laser emitter is focused on a specific range of the
reading area, a sophisticated electronic controller selects the best focused laser emitter with
respect to the code to read. This allows the reading of medium-high density codes in a large
reading area on very fast conveyors.
Barcode
A pattern of variable-width bars and spaces which represents numeric or alphanumeric data
in machine-readable form. The general format of a barcode symbol consists of a leading
margin, start character, data or message character, check character (if any), stop character,
and trailing margin. Within this framework, each recognizable symbology uses its own unique
format.
Barcode Label
A label that carries a barcode and can be affixed to an article.
Baud Rate
A unit used to measure communications speed or data transfer rate.
CD SQUARE™
CD SQUARE™ provides useful information on label position and object shape elaborated
during the barcode reading phase. This innovative technology identifies the area in which the
code is located and measures the code distance from the scanner.
CDRH (Center for Devices and Radiological Health)
This organization (a service of the Food and Drug Administration) is responsible for the
safety regulations governing acceptable limitations on electronic radiation from laser devices.
Datalogic devices are in compliance with the CDRH regulations.
EEPROM
Electrically Erasable Programmable Read-Only Memory. An on-board non-volatile memory
chip.
Full Duplex
Simultaneous, two-way, independent transmission in both directions.
Half Duplex
Transmission in either direction, but not simultaneously.
