    A decode zone simply plots working range as a function of minimum element widths of bar code symbols. Decode zones for integrated scan elements available on the PDT 7500 are provided in Appendix A, Specifications.

  • Page 53: Smart Raster Capability

    Operating the Terminal Note: Contact the Symbol Support Center if you have chronic difficulties scanning. Decoding of properly printed bar codes should be quick and effortless. Smart Raster Capability All integrated 1-D/PDF417 scan elements may be programmed for “Smart Raster” capability, which causes the scanner to emit a raster pattern dynamically optimized to the particular PDF417 bar code’s shape.

  • Page 54: Scanning Mode Options

    Make sure the terminal is programmed for a slab raster aiming pattern and Smart Raster mode. 1. Aim the scanner at the symbol. Try to keep the nose of the scanner parallel with the symbol’s rows. 2. Make sure the symbol you want to scan is within the scanning range; refer to the 1- D/PDF417 decode zones.
  • Page 55 Figure 4-2. Slab Raster Pattern on a PDF417 Bar Code 3. If the pattern is parallel to the symbol’s rows, the pattern spreads vertically to cover the symbol (Figure 4-3). If the pattern does not cover the top and bottom of the symbol, pull the scanner back until it does.
  • Page 56 PDT 7500 Series Product Reference Guide for DOS The scanner has successfully decoded the symbol when the green LED lights and you hear a short, high tone beep. Scan the Entire Bar Code Symbol The larger the symbol, the farther away you should hold the scanner to permit the raster pattern to cover the symbol (but not more than 8 inches).

  • Page 57: Scanning (Imager)

    Operating the Terminal Figure 4-5. Moving Scan Pattern Upward and Downward on “Tall” PDF Symbol The scan beam does not have to be perfectly parallel with the top and bottom of the symbol (up to a 4 tilt will work).

  • Page 58: Operational Modes

    The Imager has two modes of operation: Decode Mode and Image Capture Mode, activated by pressing the scan button. Decode zones for the Imager on the PDT 7500 are provided in Appendix A, Specifications Decode Mode In this default mode, upon pressing the scan button, the Imager attempts to locate and decode enabled bar codes within its field of view.
  • Page 59 Figure 4-8. Acceptable and Incorrect Aiming 2. The aiming pattern is smaller when the Imager is closer to the symbol and larger when it is farther from the symbol. Scan symbols with smaller bars or elements (mil size) closer to the unit, and those with larger bars or elements (mil size) farther from the unit.
