  • Page 13: Scanner Features

    1–2 Scanner Features Scanner Features The 2-D scanner emits a raster scanning pattern which is capable of scanning both: • One-dimensional bar codes • Two-dimensional bar codes (PDF417 bar codes) The scanners use a low power visible (red) laser diode for scanning, which can read color bar codes and symbols printed on just about any substrate.

  • Page 14: Led Indicators

    Scanner Features 1–3 LED Indicators On the back of the scanner there is a clear window through which two LEDs are visible. Green Green LED = Decode, indicating that a bar code symbol has been scanned and decoded. LED remains on until the next scan (trigger pressed).

  • Page 15: Safety Labels

    1–4 Scanner Features Safety Labels The scanners use a low power visible laser diode. As with any bright light source, you should avoid staring directly into the beam. Momentary exposure to a CDRH Class II laser is not known to be harmful.

  • Page 16: Smart Raster

    If the target is a 1-D bar code, the pattern never opens beyond a slab raster. If the target bar code is a 2-D (PDF417) bar code, the scanning pattern opens to a full, optimized raster pattern when the scanner is poperly aligned over the bar code.

  • Page 17: Scanning Options

    A trigger pull creates the slab raster pattern. If the target is a 1-D bar code, the pattern never opens beyond a slab raster. If the target is a 2-D (PDF417) bar code, the pattern opens to an optimized raster pattern when the scanner is properly aligned over the bar code.

  • Page 99: Advanced Data Formatting

    Appendix Advanced Data Formatting Advanced Data Formatting (ADF) provides a way to customize data before transmitting it to a host device. Scan data can be edited to meet your particular requirements. Topics in this appendix include: • Rules • Programming a Rule •...
  • Page 100 E–2 Advanced Data Formatting ADF can be implemented by scanning a related series of bar codes, which appear in the Programming Guide (Publication 2755-6.7). The table below references the page location of the ADF bar codes. ADF Bar Codes Page Special Commands Start/Save Rule Erase/Quite Rule...
  • Page 101 Advanced Data Formatting E–3 Rules ADF data is customized using rules. These rules perform detailed actions when the data meets certain criteria. One rule may consist of single or multiple criteria applied to single or multiple actions. The following describes an example of a data formatting rule: •...
  • Page 102 E–4 Advanced Data Formatting Programming a Rule When programming a rule, the rule must follow a specific format. Plan ahead before you start scanning. To program each data formatting rule: • Start the Rule. Scan the Start New Rule bar code. •...
  • Page 103 Advanced Data Formatting E–5 Criteria Code Types Select any number of code types to be affected. All selected codes must be scanned in succession, prior to selecting other criteria. If you don’t select a code type, all code types will be ignored. Code Length Define the number of characters the selected code type must contain.
  • Page 104 E–6 Advanced Data Formatting Actions Select how to format the data for transmission. • Send Data – Send all data that follows, send all data up to a specific character selected from the Alphanumeric Keyboard bar codes, or send the next N characters. N= any number from 1 to 254, selected from the Alphanumeric Keyboard.
  • Page 105 Advanced Data Formatting E–7 • Send Keystroke – Scan the Send “___ ” bar code for the keystroke you want to send. • Send Preset Value – Send Values 1 through 6 by scanning the appropriate bar code. These values must be set using the Scan Prefix or Scan Suffix bar codes located on page 1-16.
  • Page 106 E–8 Advanced Data Formatting ADF Formatting Example This section shows how ADF rules are entered and used for scan data. An auto parts distributor wants to encode manufacturer ID, part number, and destination code into their own Code 128 bar codes. The distribution center also has products that carry UPC bar codes, placed there by the manufacturer.

  • Page 108 E–10 Advanced Data Formatting Alternate Rule Sets ADF rules may be grouped into one of four alternate sets which can be turned on and off as needed. This is useful when you want to format the same message in different ways. For example, a Code 128 bar code contains the following information: Class (2 digits), Stock Number (8 digits), Price (5 digits) This bar code might look like this:...
  • Page 109 Advanced Data Formatting E–11 The sale rule may look like this. When scanning a bar code of length 15: – send the next 2 characters – send the class key – send the next 8 characters – send the stock key To switch between the two sets of rules, a “switching rule”...
  • Page 110 E–12 Advanced Data Formatting Rules Hierarchy (in Bar Codes) In addition to the correct programming of rules, you must be aware of the order of programming individual rules. Program the most general rule last. All programmed rules are stored in a buffer. As they are programmed, they are stored at the top of a rules list.

  • Page 111: Default Rules

    Advanced Data Formatting E–13 Default Rules Every unit has a default rule to send all scan data. Units with custom software may have one or more default rules burned in. The rules hierarchy will check user programmable rules first, then the default rules.
  • Page 112 E–14 Advanced Data Formatting Beeper Definitions – Error Indications When errors occur, the duration of tones very long. Beeper Sequence Indication Out of rule memory. Erase some existing rules, Low–High–Low–High then try to save rule again. (The current rule need not be re-entered).

  • Page 115 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. Asymmetric Width Growth Non-uniform growth of elements in a printer symbol. Autodiscrimination The ability of an interface controller to determine the code type of a scanned bar code.
  • Page 116 G–2 Glossary Bar Code Density The number of characters represented per unit of measurement (e.g., characters per inch in one-dimensional symbologies, characters per square inch in PDF417). 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 code.
  • Page 117 Glossary G–3 Byte On an addressable boundary, eight adjacent binary digits (0 and 1) combined in a pattern to represent a specific character or numeric value. Bits are numbered from the right, 0 through 7, with bit 0 the low-order bit. One byte in memory can be used to store one ASCII character.
  • Page 118 G–4 Glossary Code Set of unambiguous rules specifying the way in which data may be represented. Codeword In PDF417, a single group of bars and spaces (4 bars and 4 spaces, for a total of 17 module widths) which represents one or more numbers, letters, or other symbols.
  • Page 119 Glossary G–5 Dead Zone An area within a scanner’s field of view, in which specular reflection may prevent a successful decode. Decode To recognize a bar code symbology (e.g., UPC/EAN) and then analyze the content of the specific bar code scanned. To translate the bar/space pattern into defined characters within a defined symbology.
