Glossary–1 SCANTEAM 3700 GLOSSAR Y AIM– is the Automatic Identification Manufacturers, Inc. AIM is an industry organization that supports the application of all varieties of automatic identification technology including bar codes.
Glossary–2 Buffer– refers to a storage facility in a data communications system which can compensate for a difference in time or rate of data transmission. Byte– is a group of 8 bits handled as a unit. Character (Bar code)– is group of bars and spaces which represents a single number , letter , mark or other graphic element.
Glossary–3 Digital – (used in contrast to Analog) describes a coded squarewave signal (processed from an analog signal) which is utilized by decoding circuitry . Digital bar code is generally square wave pulses (0 to 5 volts) with widths which depict the bar and space widths in the code.
Glossary–4 Minimum and Maximum Message Lengths – refers to how the various symbologies may be restricted in code length to minimize the chances of misreading a bar code. By setting the message length, the decoder will count the data characters plus any others (start/stop, check digit, etc.
Glossary–5 Scan Rate – is the number of times a laser ’ s scanning beam passes through the exit window in one second. Scan V elocity – is the speed of a laser ’ s scanning beam on a target at a given distance from the front of the scanner or rotating polygon mirror .
