Page 14: Holographic Scanning Disc
2–2 Hardware Features Holographic Scanning Disc The rotating holographic disc takes the place of a focusing lens, light collection lens, and a rotating mirror. The disc contains 15 to 21 separate holographic sectors. Each sector has its own focal distance, light collection aperture, and mirror scan angle. -
Page 15: Disc Operation
Hardware Features 2–3 Disc Operation As the disc rotates, the laser beam hits the disc. The laser beam is then projected onto the mirror and then projected out through the reader’s window. The reflected light travels toward the mirror. The reflected light is then projected onto the rotating disc where it is detected by an internal sensor. -
Page 16: Interface Box Features
2–4 Hardware Features Interface Box Features The interface box routes signals between the readers and an external package detect. The interface box has the following components: Power transformer. Supplies a stepped down and isolated voltage that produces the 12V dc power for the interface box and external sensor. -

Page 22: Designing Your System
Chapter Designing Your System This chapter provides the information needed to set up a scanner system correctly. Items include: setup goals symbol height and length symbol quality symbol orientation tilt, pitch, and skew determining read range Setup Goals Each application must be evaluated carefully. Successful bar code scanning begins with quality bar code symbols and the correct number, type, and location of readers, decoders, and package sensors. -
Page 23: Symbol Height And Length
3–2 Designing Your System Symbol Height and Length The height is measured from one end of a bar to the other, and its length is always the distance from one end of the symbol to the other, including the Quiet Zones. A Quiet Zone is the empty space before or after the bars, and is usually equal to 10 times the Narrow Element Width. -
Page 24: Symbol Orientation
Designing Your System 3–3 Symbol Orientation Bar code symbols must have the correct aspect ratio to be read by the reader. A scan line must cross every bar, space, and both quiet zones on the same sweep. Correct: All bars are crossed by a scan line Not Correct:... -
Page 25: Tilt
3–4 Designing Your System Tilt A symbol is tilted when the symbol’s bars are not 90 to one of the scan lines. The symbol can be read with any tilt, provided a scan line passes through all bars and quiet zones on each sweep for the required minimum number of scans. -
