  • Page 17: Overview

    5-5. These scanners read bar codes printed on all substrates. Typical Applications The LS 1220 Wide Angle Scan Engine features a broad 60° scan angle to accommodate larger bar codes within extremely close range. The LS1220WA is ideal for high-volume, near-contact scanning such as Kiosks, ATM, Lottery Machines and other applications that require superior scanning performance in a complete package.

  • Page 18: Theory Of Operation

    Introduction Figure 1-1. LS 1220 Theory of Operation A laser diode produces a single beam of coherent light which is deflected off of an oscillating mirror to create the laser scan beam. When the laser light strikes a bar code, the dark bars absorb the laser light and the light spaces reflects it.

  • Page 20 Introduction Decoder The Decoder contains a micro-controller that provides the capability for bar code decoding, host I/O interface protocol, and other decoder functions. The micro-controller contains a watchdog timer. The enabling/disabling and maintenance of this watchdog are totally internal to the decoder; the host can not configure the watchdog. The Decoder’s reset circuitry holds the micro-controller in reset after power up to allow sufficient time for hardware initialization.
  • Page 21 LS 1220 Product Reference Guide Motor Driver The Motor Driver is an electromagnetic and electronic circuit that provides feedback control of the mylar motor scan element. The circuit regulates the scan amplitude of the motor/ mirror assembly. The scan frequency is determined by the resonance characteristics of the mechanical design.

    Bar Height The dimension of a bar measured perpendicular to the bar width. Bar Width 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 measure of the data flow or number of signaling events occurring per second.
  • Page 123 Those characters available for encodation in a particular bar code symbology. Check Digit A digit used to verify a correct symbol decode. The scanner inserts the decoded data into an arithmetic formula and checks that the resulting number matches the encoded check digit. Check digits are required for UPC but are optional for other symbologies.
  • Page 124 Continuous Code A bar code or symbol in which all spaces within the symbol are parts of characters. There are no intercharacter gaps in a continuous code. The absence of gaps allows for greater information density.
  • Page 125 A condition which occurs when the data output of a reader or interface (Misdecode) controller does not agree with the data encoded within a bar code symbol. MSI Plessey A numeric-only bar code type. It can accept a variable number of digits up to 13.
