WiseWand 2

Bar Code Scanner

The WiseWand 2 (WW2) is a handheld wand-type scanner designed for reading and decoding barcodes. The WW2 converts the barcode data into AT/PS2 compatible keycodes and transmits this data into the external keyboard port of a personal computer. The WW2 is powered by voltage available from the port to which it is connected, making it ideal for use with palmtop and notebook computers where external power would be cumbersome. The WW 2 will, of course, reduce the otherwise obtainable battery life of the host computer.

The WW2 barcode decoder automatically discriminates among 9 popular barcode symbologies including Code 39, Extended Code 39, Codabar, Interleave 2 of 5, Code 128, UPC A, UPC E, EAN/JAN 8 and EAN/JAN 13.

The WW2 has a six foot coiled cable with a mini-DIN type PS2 keyboard input connector. Included with the WW2 is, a clip to secure the decoder module to the host equipment, the bar coded programming menu and the user's manual (on diskette).

Configurable Parameters

Delimiter - A unique character code that is used to delineate the beginning and end of a data string when the auto time and/or date stamps are used. Set this value to zero if no delimiters are desired.

Terminator(s) 1 & 2 - These are the ASCII characters used to mark the end of a stored record in the data buffer. When data is uploaded, these characters terminate each record. If only one terminator is used, set Terminator 2 to null (zero).

Symbologies and Symbol Limits

Each barcode symbology can be selectively enabled or disabled. Typically only the needed symbologies are enabled to improve misread performance. The variable length symbologies (code 39, codabar, I 2/5 and code 128) can be filtered to only allow a range of symbol lengths. Each symbology can have a minimum and a maximum length. The minimum length can be set equal to the maximum length to accept only one length symbol. The minimum or maximum range check can be disabled by setting both values to zero.

Several of the barcode symbols have special options that can be enabled or disabled. These are defined as follows:

Code 39 Extended - Allows full ASCII character set expansion using the extended code 39 standard.

Code 39 Check Digit - Interprets the last code 39 character as a check code character.

Code 39 Check Output - Allows the code 39 check code character to be included in the resulting ASCII data string (record).

Code 39 Concatenation - Will combine multiple code 39 symbols into one string if the first character of each string is a space (20H).

Codabar Start/Stop - Allows the start & stop codes to be included in the CODABAR character string.

UPC/EAN Number Digit - Allows the 1st digit (number system) to be included in the symbol character string.

UPC/EAN Check Digit - Allows the last digit (check digit) to be included in the symbol character string.

Menu Programming

The WW2 can only be configured using the 'Programming Menu'. Some of the typical programming sequences follow here. An audible "beep" will occur for each successful scan of a menu bar code, proceed as follows:

  1. To begin programming scan the "ENTER" programming symbol.
  2. Then scan the desired feature symbol.
  3. Scan an appropriate selection symbol(s). This could be 'ENABLE', 'DISABLE' (i.e. after a symbology or symbol option), a number (for baud, limits, etc), a string of characters (for post-amble or pre-amble) etc.
  4. When programming is complete, scan the "EXIT" programming symbol and the WW2 will return to the data collection mode.

Menu Programming Examples:

Load Defaults - To re-programs the WW2 with the default configuration.

  1. Scan "ENTER" under the PROGRAMMING column
  2. Scan "LOAD DEFAULTS" under the PROGRAMMING column.
  3. Scan "EXIT" under the PROGRAMMING column.

Enable/Disable - Any of the features that can be either enabled or disabled (symbols, checksum character, etc.) should use the 'ENABLE' or 'DISABLE' selection symbols. For example, to Enable Extended Code 39 using the ASCII menu

  1. Scan "ENTER" under the PROGRAMMING column.
  2. Scan "EXTENDED CODE 39" under the OPTIONS column.
  3. Scan "ENABLE" under the SELECTIONS column.
  4. Scan "EXIT" under the PROGRAMMING column.

Values - Any of the features that require a value (Baud, limits, etc.) can use from 1 to 3 digits of the numeric selection symbols. To set the minimum CODE 128 barcode length to 6 characters.

  1. Scan "ENTER" under the PROGRAMMING column.
  2. Scan "CODE 128 MIN (0-32)" under the LIMITS column.
  3. Scan "6" under the SELECTIONS column.
  4. Scan "EXIT" under the PROGRAMMING column.

Preamble/Postamble - To program a preamble using the programming menu;

  1. Scan "ENTER" under the PROGRAMMING column.
  2. Scan "PREAMBLE" under the PROGRAMMING column.
  3. Scan "ENABLE" under the SELECTIONS column.
  4. Scan each character in order that makes up the string from the Code 39 Full ASCII Character Set on the back of the menu (up to 20 characters).
  5. Scan "ENABLE" under the SELECTIONS column again.
  6. Scan "EXIT" under the PROGRAMMING column.

To disable the preamble;

  1. Scan "ENTER"
  2. Scan "PREAMBLE"
  3. Scan "DISABLE"
  4. Scan "EXIT"

Use the same sequence for programming and disabling the postamble except substitute "POSTAMBLE" for "PREAMBLE".

The PREAMBLE is a string of up to 20 characters (key codes) which are to be inserted at the beginning of each scanned barcode data string. The PREAMBLE is programmed into the WW2 with the Programming Menu as follows:

The POSTAMBLE is a string of up to 20 characters (key codes) which are to be appended to the end of each decoded barcode data string. The POSTAMBLE is programmed into the WW2 exactly like the PREAMBLE string (described above).
