Components Symbology Specific Notes
IDAutomation provides several
Barcode Components
with support for multiple symbologies. This page provides helpful information
for various symbologies available within
IDAutomation Barcode Components.

| CODE 128 |
The "AUTO" setting for Code 128 will automatically switch
character sets as necessary to compact numbers in character
set C and encode functions in character set A. The IDAutomation
implementation of
Code 128
auto offers many options when ApplyTilde is enabled:
-
ASCII
Characters may be encoded by using the format
~???. For example, the text
of BAR~009CODE~013 will
actually encode BAR <tab> CODE <return>.
-
GS1-128 and
FNC1 Functions (aka: UCC/EAN-128)
may be encoded with ASCII 202 (character
Ê,) or
~202 as the FNC1 before each
application identifier (AI). For example, the GS1 data of
(8100)712345(21)12ECC200 should be entered as:
~2028100712345~2022112ECC200.
In most cases, the AIs will be properly represented in the
human readable text. If the parentheses are not around the
correct number for the AI, enter the following as the FNC1
for the correct number of digits in the AI:
ASCII 212 or ~212 = 2 digits
ASCII 213 or ~213 = 3 digits
ASCII 214 or ~214 = 4 digits
ASCII 215 or ~215 = 5 digits
ASCII 216 or ~216 = 6 digits
ASCII 217 or ~217 = 7 digits
For example, to encode (1277)128200, enter
~2141277128200.
Note: IDAutomation products with build dates
May 2009 or later include functionality that allows users
to add application identifiers by adding the parentheses
where needed when apply tilde set to true and the code 128
character set is auto.
-
Mod 10 Check-digits may be generated by using the
format ~m?? where
?? is the number of characters
preceding the tilde in which to base the Mod 10 calculation.
The additional MOD 10 check digit is commonly used in
GS1, UCC and EAN barcode types.
-
FNC2 Functions may be inserted into the DataToEncode
string by using ASCII 197 or ~197. For example; Å8012349091.
The
IDAutomation USB Barcode Scanner may be programmed to
hold the barcode starting with the FNC2 in memory and only
transmit it to the computer after scanning a barcode containing
the FNC1.

| POSTNET,
PLANET and Intelligent Mail |
The X Dimension (or NarrowBarWidth) of
0.045 CM or 19 MILS should be used for all USPS barcode symbologies.
For barcodes to be accepted by U.S. Post Offices, they must
be between 22 and 24 bars per inch. The setting of 0.045 CM
or 19 MILS should produce about 23 bars per inch. If results
are different, adjust this property accordingly. To
adjust the size of
Intelligent Mail, the ascender, descender
and full bar heights are all a function of the tracking bar
height, which is controlled with the PostnetHeightShortBar
property. |
UPC-A,
UPC-E, EAN-8 and
EAN-13 |
The text size and font may need to be
adjusted with these barcode symbologies depending on the implementation
and resolution. The +2 and +5 add-on codes may be encoded by
appending them to the end of the data to encode string. If the
check digit is added, it will be ignored and regenerated to
ensure that the code can be scanned. The margins may need to
be increased when using these symbologies. |
|
UCC128 |
This symbology option encodes an even
number of number digits and includes an FNC1 character in set
C.
Code 128 Auto must be used to encode additional FNC1 codes
or data containing text or odd numbers. Use the UCC128 function
only for GS1-128 applications where the input data is an even
number and only one AI is needed, such as in SSCC-18 and SCC-14
barcodes. |
