  • Page 101 Glossary ASCII American Standard Code for Information Interchange. A 7 bit-plus-parity code representing 128 letters, numerals, punctuation marks, and control characters. It is a standard data transmission code in the U.S. Binary digit. One bit is the basic unit of binary information. Generally, eight consecutive bits compose one byte of data.
  • Page 102 G–2 Codabar A discrete self-checking code with a character set consisting of digits 0 to 9 and six additional characters: (- $ : / , +). Code 128 A high density symbology which allows the controller to encode all 128 ASCII characters without adding extra symbol elements.
  • Page 103 G–3 Decode To recognize a bar code symbology (e.g., UPC/EAN) and then analyze the content of the specific bar code scanned. Decode Algorithm A decoding scheme that converts pulse widths into data representation of the letters or numbers encoded within a bar code symbol. Discrete Code A bar code or symbol in which the spaces between characters (intercharacter gaps) are not part of the code.
  • Page 104 G–4 International Electrotechnical Commission. This international agency regulates laser safety by specifying various laser operation classes based on power output during operation. Intercharacter Gap The space between two adjacent bar code characters in a discrete code. Interleaved Bar Code A bar code in which characters are paired together, using bars to represents the first character and the intervening spaces to represent the second.
  • Page 105 G–5 Laser An acronym for Light Amplification by Stimulated Emission of Radiation. The laser is an intense light source. Light from a laser is all the same frequency, unlike the output of an incandescent bulb. Laser light is typically coherent and has a high energy density. Laser Diode A gallium-arsenide semiconductor type of laser connected to a power source to generate a laser beam.
  • Page 106 G–6 Scanner An electronic device used to scan bar code symbols and produce a digitized pattern that corresponds to the bars and spaces of the symbol. Its three main components are: 1. Light source (laser or photoelectric cell) - illuminates a bar code. 2.
