    Symbologies
    Introduction
    This programming section contains the following menu selections.  Refer to 
    Chapter 10 for settings and defaults.
    All Symbologies
    If you want to decode all the symbologies allowable for your image scanner, 
    scan the All Symbologies On code.  If on the other hand, you want to decode 
    only a particular symbology, scan All Symbologies Off followed by the On sym-
    bol for that particular symbology.All SymbologiesInterleaved 2 of 5

    Message Length
    You are able to set the valid reading length of some of the bar code symbologies.   
    If the data length of the scanned bar code doesn’t match the valid reading length, 
    the image scanner will issue an error beep.  You may wish to set the same value 
    for minimum and maximum length to force the image scanner to read fixed 
    length bar code data.  This helps reduce the chances of a misread.
    EXAMPLE:Decode only those bar codes with a count of 9-20 characters.
    Min. length = 09 Max. length = 20
    EXAMPLE:Decode only those bar codes with a count of 15 characters.
    Min. length = 15 Max. length = 15
    For a value other than the minimum and maximum message length defaults, 
    scan the bar codes included in the explanation of the symbology, then scan the 
    digit value of the message length and Save bar codes on the Programming Chart 
    inside the back cover of this manual.  The minimum and maximum lengths and 
    the defaults are included with the respective symbologies.

    Codabar
    Codabar Start / Stop Characters
    Start/Stop characters identify the leading and trailing ends of the bar code. You 
    may either transmit, or not transmit Start/Stop characters.  
    Default = Don’t Transmit.
    Codabar Check Character
    Codabar check characters are created using different “modulos.”  You can pro-
    gram the image scanner to read only Codabar bar codes with Modulo 16 check 
    characters. 
     Default = No Check Character.
    No Check Character
     indicates that the image scanner reads and transmits bar 
    code data with or without a check character.
    When Check Character is set to 
    Validate and Transmit, the image scanner will 
    only read Codabar bar codes printed with a check character, and will transmit 
    this character at the end of the scanned data.

    When Check Character is set to Validate, but Don’t Transmit, the unit will only 
    read Codabar bar codes printed with a check character, but will not transmit the 
    check character with the scanned data.
    Codabar Concatenation
    Codabar supports symbol concatenation.  When you enable concatenation, the 
    image scanner looks for a Codabar symbol having a “D” start character, adja-
    cent to a symbol having a “D” stop character.  In this case the two messages 
    are concatenated into one with the “D” characters omitted.
    Select Require to prevent the image scanner from decoding a single “D” Coda-
    bar symbol without its companion.  This selection has no effect on Codabar 
    symbols without Stop/Start D characters.

    Code 39 Check Character
    No Check Character indicates that the image scanner reads and transmits bar 
    code data with or without a check character.
    When Check Character is set to Validate, but Don’t Transmit, the unit only 
    reads Code 39 bar codes printed with a check character, but will not transmit 
    the check character with the scanned data.  
    When Check Character is set to Validate and Transmit, the image scanner 
    only reads Code 39 bar codes printed with a check character, and will transmit 
    this character at the end of the scanned data.  
    Default = No Check Character.
    Code 39 Message Length
    Scan the bar codes below to change the message length.  Refer to Message

    Code 39 Append
    This function allows the image scanner to append the data from several Code 
    39 bar codes together before transmitting them to the host computer.  When this 
    function is enabled, the image scanner stores those Code 39 bar codes that 
    start with a space (excluding the start and stop symbols), and does not immedi-
    ately transmit the data.  The image scanner stores the data in the order in which 
    the bar codes are read, deleting the first space from each.  The image scanner 
    transmits the appended data when it reads a Code 39 bar code that starts with 
    a character other than a space.  
    Default = Off.
    Code 32 Pharmaceutical (PARAF)
    Code 32 Pharmaceutical is a form of the Code 39 symbology used by Italian 
    pharmacies.  This symbology is also known as PARAF..

    Full ASCII
    If Full ASCII Code 39 decoding is enabled, certain character pairs within the bar 
    code symbol will be interpreted as a single character.  For example:  $V will be 
    decoded as the ASCII character SYN, and /C will be decoded as the ASCII 
    character #.  
    Default = On.
    Character pairs /M and /N decode as a minus sign and period respectively.
    Character pairs /P through /Y decode as 0 through 9.

    Code 39 Code Page
    Code pages define the mapping of character codes to characters.  If the data 
    received does not display with the proper characters, it may be because the bar 
    code being scanned was created using a  code page that is different from the 
    one the host program is expecting.  If this is the case, scan the bar code below, 
    select the code page with which the bar codes were created from the chart, 
    Code Page Mapping of Printed bar codeson page A-6, and scan the value and 
    the SAVE bar code from the Programming Chart inside the back cover of this 
    manual.  The data characters should then appear properly.

    Check Digit
    No Check Digit indicates that the image scanner reads and transmits bar code 
    data with or without a check digit.
    When Check Digit is set to Validate, but Don’t Transmit, the unit only reads 
    Interleaved 2 of 5 bar codes printed with a check digit, but will not transmit the 
    check digit with the scanned data.
