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...

Codabar

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.

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”...

Scan the bar codes below to change the message length.  Refer to Message 
Lengthon page 6-2 for additional information.  Minimum and Maximum
lengths = 2-60.  Minimum Default = 4, Maximum Default = 60.

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

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...

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,

When Check Digit is set to Validate and Transmit, the image scanner only 
reads Interleaved 2 of 5 bar codes printed with a check digit, and will transmit 
this digit at the end of the scanned data.  
Default = No Check Digit.

Scan the bar codes below to change the message length.  Refer to Message
