IDAutomation Data Matrix Font and Encoder
Manual
DEMO NOTICE:
The demo version of this product will produce larger symbols because the text
of "DEMO<CR><LF>" is encoded in each symbol with the data that is being encoded.
In addition, many of the VBA modules are password protected and the Native Crystal
Encoder is not provided. The
purchased version
does not include these limitations.

The IDAutomation Data Matrix Font and Encoder is a collection of components
that generate Data Matrix symbols with fonts and graphics.
Large amounts of text and binary data can be
stored in a single barcode symbol with the Data Matrix symbology. The symbol
can withstand some damage without causing loss of data with Reed Solomon error correction
that is a requirement of all ECC200 symbols. ECC200 is the recommended ISO and AIM
standard of error correction used in the symbols. This high level of error correction
decreases
chances of read errors and is far more advanced than one dimensional barcodes
with check digits. Up to about 850 characters may be
dependably encoded
and read from each symbol with the Data Matrix symbology.
The version of Data Matrix
provided in this package includes support for Structured
Append, which allows thousands of characters to be encoded into multiple symbols.
Additionally, all IDAutomation DataMatrix products support ECC200 by default. This
advanced Data Matrix font uses IDAutomation Vertical Interleaved Technology™
which allows increased throughput and printing at smaller X dimensions than competitors'
products.
The encoders provided in this package return a text string that, when printed
or displayed with the Data Matrix font, create the Data Matrix symbol. It is necessary
to use the encoder because of the complexity of the symbology. Please review the
Data Matrix
Encoder for Windows® Tutorial for a simple encoder usage example.
The following font encoders
are provided:
In addition to the font encoders provided, graphic encoders are also included
in this package. The graphic encoders are components that return a graphic image
of the complete symbol instead of text that needs to be combined with a font.
The following graphic
encoders are provided:
In the event the font encoders and
graphic encoders provided are not supported
in the desired application, there are a few other implementation options available:
- Data Matrix may be printed on an unsupported system by using a
font encoder to populate a database
with the "text string to print" and by accessing the database from the other
system with the Data Matrix font.
- The source code for any single encoder (available
in Java, C++, C# .NET or Visual Basic 6) will be supplied with the purchase
of the Unlimited Developer License and a signed
source code license
agreement. VB 6 source code is automatically supplied with
any Developer License purchase and consists of about 5000 lines of code.
- IDAutomation
Barcode Label Software
Professional may be a good alternative. It is a stand alone label design
application with VB scripting support and database connectivity.
- IDAutomation
Image Generators create images one at a time on Windows systems. Command
line options are also available with this product.
Extract the file(s) provided with the product and run the installation executable.
The installation executable will install the files needed in the application folder
under Program Files, and the following components:
- Data
Matrix Encoder for Windows - An application that provides an easy method
for users to create Data Matrix barcodes and print or paste them into other
applications.
- TrueType Font - The Data Matrix ECC-200
font named IDAtomationDMatrix.
- Crystal Reports UFL - Allows use of the Data Matrix
fonts from Crystal Reports, compatible with version 9 and above.
- ActiveX Control - A
graphic encoder for use in Access,
Excel, Visual Basic, Visual Foxpro and C++.
- Windows DLL - This component is installed
in the Windows System32 folder and is used as the font encoder for Windows applications.
-
Signed ActiveX CAB File - The CAB file may be used with Infopath, Internet
Explorer and FrontPage.
- VBA Module - The module may be used in Visual
Basic, Excel or Access.
- Visual Basic Source Code - the source code
used to create the
Data
Matrix Encoder for Windows is also supplied. The source code for generating
Data Matrix from any other single encoder may be provided with the purchase
of the Unlimited Developer License and a signed
source code agreement.
- Microsoft Office Examples are provided for
Word mail-merge and Access.
Data Matrix fonts cannot be used directly in Excel because the method Excel
uses to display and print fonts is incompatible with stacked barcodes. To print
barcodes from Excel, it is recommended to use the graphic encoder
ActiveX Control or Word Mail-Merge. Additionally,
IDAutomation offers Barcode
Label Software that can easily print barcodes from data in Excel and other
databases.
If it is necessary to verify Data Matrix barcodes, consider purchasing a
Data Matrix Symbol Verifier
or a Data Matrix Imager.
The VBA module is required when using the
font encoders in VB 6, Excel or Access; it is provided in two forms:
- The IDAutomation_Datamatrix_Macro.bas module
accesses the ActiveX DLL for the encoder function. Created in C++, the ActiveX
DLL is faster than the native VBA code. However, the installation executable
provided in the package must be installed on each computer using this module
for proper operation.
- The IDAutomation_Native_Datamatrix_Macro.bas
module is the complete encoder function in "native" Visual Basic form (VBA).
With the exception of the Java Encoder, it is the only encoder that is compatible
with both Windows and the Macintosh. When distributing an application with this
module, the ActiveX DLL does not need to be installed or distributed.
This module is only supplied in the purchased version of the Advantage Package.
Importing the module:
- Extract the files provided with the product.
- Open VB, Excel or Access.
- If Excel or Access is being used, choose Tools - Macro - Visual Basic
Editor to open the VB editor.
- If the IDAutomation_Datamatrix_Macro.bas module
is to be imported, run the installation executable in the package and go to
Tools - References and select IDAutomation Data Matrix Barcode, click
OK.
- Choose File - Import File and select the module to import from the
VBA folder of the extracted files. The native module,
IDAutomation_Native_Datamatrix_Macro.bas, is compatible with Windows
and the Macintosh but is only supplied in the purchased version of the product.
- If Excel or Access is being used, choose File - Close to close the
VB editor and choose File - Save.
- After the file is imported, the IDAutomation_DataMatrix function may be
called according to the chart below. The zero digit is the default for all parameters
(which are optional) and is used for automatic mode or a false setting. The
one digit is used for a true setting.

In Microsoft Access, there are three implementation options, two of which are
supported in this package. When used in reports and forms, the graphic encoder option
may be the easiest product to use.
Graphic encoder implementation:
- Run the installation executable in the package and follow the instructions
to complete the installation.
- Open a report in Design Mode.
- Choose Insert - ActiveX control and choose the IDAutomation Data Matrix
control.
- Move and size the control necessary. To change the properties of the control
such as height and symbology type, right-click on the control and choose Properties.
- To bind the control to a data source, enter the table and field or formula
in the control source field. The proper barcode will show up after the report
is saved and executed.
- Additional implementation information is provided in the
ActiveX Control Manual.
Font implementation:
- Run the installation executable file in the package and follow the instructions
to complete the installation.
- Import the VBA module into the database.
- Open a report in Design Mode.
- Add a text field to the report that is to contain the barcode. Size it appropriately,
to be large enough to contain the symbol. Change the font point size of the
field to 8 points.
- Right-click on the text field and enter the function call as a formula in
the control source property. For example:
=IDAutomation_Native_DataMatrix([Test Data.data])
The following formula combines two fields into a single symbol and inserts
a tab function between them
=IDAutomation_Native_DataMatrix([Test Data.TextData] &
Chr(9) & [Test Data.NumberData])
- Save the report and run it; several numbers should appear in the text field.
This is the data that will create a correct barcode when combined with the Data
Matrix Font.
- Open the report in design mode and select the IDAutomationDMatrix font for
the text field. The recommended point size is
8 points.
- Save the report and run it; a correct symbol should appear in the text field.
Graphic encoder embedding:
Although it is not part of this package, the
Data Matrix Native Barcode Generator
for Access is also available, which creates barcodes without any additional
fonts, ActiveX or plug-ins.
Data Matrix barcodes may be created in a Word mail-merge if Excel is used as
the data source with the following procedure:
- Extract the files provided with the product.
- When using Windows, run the installation executable in the package to install
the IDAutomationDMatrix font. Macintosh users should follow the
Font
Installation Procedures to install the IDAutomationDMatrix font.
- Import the VBA module into the Excel spreadsheet
that will be used as the data source. When using the Macintosh, the native module,
IDAutomation_Native_DataMatrix_Mac.rtf must be used.
(Because Office 2004 for Mac does not have an import feature, users will need to
copy the RTF file manually by going to Tools - Macros - Visual Basic Editor.
Once the editor window is open, go to Insert - Module and paste the contents of
the RTF file.)
- Place a title in each column of the spreadsheet on row 1 that will contain
the data, and then import the data into the Excel spreadsheet.
- Select a blank column on row 1, to the right of the last populated column
in the spreadsheet, and title it Barcode.
- Add a formula on row 2 of the Barcode column that calls the function as
a formula.
- For example, the following formula adds columns A and B to the barcode:
Windows Example:
=SUBSTITUTE(Encn_DM(A2&B2),CHAR(10),"")
Macintosh Example:
=SUBSTITUTE(Encn_DM(A2&B2,0,0,-1),CHAR(10),"")
- The following formula adds just column A to the barcode, with some
optional
parameters:
=SUBSTITUTE(Encn_DM(A2,1,0,3),CHAR(10),"")
- The following formula adds columns A, B and C to the barcode and separates
them with a comma delimiter:
Windows Example:
=SUBSTITUTE(Encn_DM(A2&","&B2&","&C2),CHAR(10),"")
Macintosh Example:
=SUBSTITUTE(Encn_DM(A2&","&B2&","&C2,0,0,-1),CHAR(10),"")
- Highlight the cell with the formula in it and choose Edit - Copy.
- Select the entire range of cells to paste this formula into in the Barcode
column and choose Edit - Paste.
- Follow the procedures in Word to add this spreadsheet as the data source
the mail merge.
- Add the mail merge field of Barcode to place the barcode in the document.
- Highlight the «Barcode» merge field and select the IDAutomationDMatrix
font.
- After the mail-merge is performed, the barcodes should appear in the merged
documents.
- A working example is provided in the Word Mail-Merge.doc
file included with the Windows install package.
IDAutomation provides two font encoders
in this package for Crystal Reports:
- The UFL Formula
accesses the ActiveX DLL and Crystal UFL for the font encoder function. Created
in C++, the ActiveX DLL is faster than the native formula. However, when distributing
the report, the Windows installation executable file must also be installed.
- The Native Formula
is the complete font encoder function that may be embedded in a report. It is
much slower than the UFL formula. However, when distributing a report, no other
components are required except the Data Matrix font. Additionally, the slower
speed may not be an issue when encoding less than 40 characters. This
formula is only supplied in the purchased version of the Advantage Package.
Although not part of this package, IDAutomation offers two other implementations
in Crystal that may be a better solution for the desired application:
Limitations with Crystal Reports
prior to version 9:
The Crystal Reports UFL is designed to work with Crystal Reports 6.0 and above.
However, because of a Crystal Reports limitation prior to Version 9, only limited
information (up to about 40 ASCII characters) may be encoded; To overcome this limitation,
version 9 or greater is required.
Crystal Reports version 9 (and later versions) overcome the 254 character limitation
by using a formula that is able to retrieve the data encoded in 254 byte chunks.
A simple example of creating a Data Matrix barcode in Crystal is included in the
Font and Encoder package. IDAutomation recommends referring to that example if problems
are encountered.
How the Font and Encoder Works with Crystal Reports:
After installing the
Data Matrix Font and Encoder for Windows, the encoder functions will be operative
in Crystal Reports.
- The IDAutomationDataMatrixEncoderDMSet
function returns the number of data segments contained in the barcode and sets
up the barcode for retrieval. All fields passed to the encoder set function
must be text fields or they must be converted to text.
- The IDAutomationDataMatrixEncoderDMGet
function returns a string for the designated data segment. A correct barcode
string is achieved when all data segments are combined.
- When the barcode string is combined with IDAutomation's Data Matrix font,
it will produce a Data Matrix barcode.
How to Create a Data Matrix Barcode with Crystal Reports:
- Choose View - Field Explorer. Select Formula Fields. Right click and select
New. Enter a name to identify the formula created and choose OK.
- The Formula Editor should now appear.
- When the Native Formula is used, change
the Formula Syntax to Basic Syntax. Copy and paste the text from the file
"Native Formula for IDAutomation DataMatrix Fonts.txt"
into the Formula Editor dialog box. The Native
Crystal Report Example.rpt file is provided in this package as
an example, and may be referred to for troubleshooting purposes.
- When the UFL Formula is used, copy and
paste the code below into the Formula Editor dialog box. The
Crystal Reports Example.rpt file is provided
in this package as an example, and may be referred to for troubleshooting
purposes:
stringVar DataToEncode:= {Table.Field};
stringVar CompleteBarcodeString:="";
numberVar i:=0;
numberVar Segments:= IDAutomationDataMatrixEncoderDMSet(DataToEncode,0 ,0
,0 );
For i:=0 to Segments Do
(
CompleteBarcodeString := CompleteBarcodeString + IDAutomationDataMatrixEncoderDMGet(i);
);
CompleteBarcodeString
- Change the DataToEncode = section of the formula
so it encodes fields from a database. Save the formula.
-
The field where the barcode is to be placed on the report must allow multiple
lines, because the formula draws the symbol line-by-line. Format the field
so that all borders are removed; borders will usually cause scanning problems.
Size the field so that it is large enough to contain the barcode.
-
Choose File - Print Preview or the Preview tab. A series of many characters
will be visible in the text field; this is normal.
-
After the font of the field is changed to the Data Matrix Font (IDAutomationDMatrix)
a correct symbol will be created.
There are a number of ways to format the data being encoded. It is also possible
to combine multiple fields and place functions in a single barcode. The most common
functions are CHR(9) for tab and
CHR(13) for a return. For example:
- The following formula combines two fields in a single barcode and places
a tab function between them:
stringVar DataToEncode:= {Table1.DataField1}
& CHR(9) & {Table1.DataField2};
- The following formula places a tab function and a return function after
the barcode:
stringVar DataToEncode:= {Table1.DataField1}
& CHR(9) & CHR(13);
- The formula below combines two fields with the date function:
stringVar DataToEncode:= {Table1.DataField1} & CHR(9) & {Table1.DataField2}
& CHR(13) & CurrentDate;
Refer to the Crystal Reports
documentation for additional information about creating reports with formulas. If
it is necessary to verify barcodes, consider purchasing a
Barcode Verifier or
Hand-Held Scanner.
The Native JavaScript Font Encoder is a complete font encoder in a single JavaScript
file; no other components need to be installed to create barcodes except the IDAutomationDMatrix
font. This product is only provided in the purchased version of the Advantage Package.
The following describes how to use the Native JavaScript Font Encoder in HTML:
- Open the HTML document or application that the barcode is to be integrated
with.
- Add the following line at the top of the file just before the
</head> line to load the appropriate JavaScript
file:
<script language="JavaScript" src="IDAutomation_DataMatrix_Font_Encoder.js"></script>
- Add a script where the barcode is to appear in the HTML document or text
object, which is the file name without the ".js":
<font face="IDAutomationDMatrix" size="2">
<script type="text/javascript">
document.write(IDAutomation_DataMatrix_Font_Encoder("Created
with the IDAutomation.com Native JavaScript Font Encoder"));
</script></font><p>
- Modify "DataToEncode" with what is to be encoded in the barcode. This may
be accomplished with a "variable" in JavaScript or a
dynamically generated
webpage.
JavaScript Font Encoder Parameters |
Result = (DataToEncode As String, Optional
ProcessTilde, Optional
EncodingMode, Optional
PreferredFormat, Optional
HTML) |
Example:
IDAutomation_DataMatrix_Font_Encoder("ECC200_123456789012",false,2,29)); |
The HTML property sets the value for the carriage return
that draws the barcode. If HTML is true (the default setting), the carriage return
is <br> for use in HTML only. If it is false, the carriage return is an ASCII 13
+ ASCII 10 which is a return and line feed.
Microsoft
.NET Integration |
Implementation of Data Matrix in .NET applications may be accomplished with graphic
or font encoders. Integration into ASP.NET and other web applications is best implemented
as a graphic encoder with the
ASP.NET
Web Component provided in this package. Information about
printing from the .NET Forms Control
without using the font is provided in the
.NET Forms
Control Manual..NET Font Encoder Example:
The following is an example that uses the font encoder to obtain the data, that
when printed with IDAutomation's Data Matrix Font, will create a correct barcode.
The source code for this font encoder example is provided in the package for testing
and reference.
- In a .NET project, add a reference to the DLL and place the import statement
in the declarations section of the project. For example:
Imports IDAutomation.Windows.Forms.Data
MatrixBarcode
- Obtain the string of data, that when printed with IDAutomation's Data Matrix
Font, will create a correct symbol:
Dim NewBarcode
As Data MatrixBarcode = New
Data MatrixBarcode()
TextBox2.Text = NewBarcode.FontEncoder(TextBox1.Text, 0, 0, 0,
False, Data MatrixBarcode.Data MatrixModes.Text,
True)
This section describes the font encoder process in Java. Implementation in Java as a graphic encoder is described in the
Java User Manual.
Install the Encoder Class Library:
Copy everything in the "Java Class Encoder" directory to the root directory of
the system's Java classpath. Consult the Java documentation or the company that provided
the Java virtual machine for assistance.
Integrate the Font Encode Method:
After the directories are copied to the classpath root, the method to format
data to the font can then be called from a method in a Java application as in this
example:
import java.io.*;
import com.idautomation.fontencoder.datamatrix.*;
class DMatrixTest
{
public static void main ( String [] args )
{
String dataToEncode = "Data Matrix Test";
DataMatrixEncoder dme=new DataMatrixEncoder();
System.out.println( dme.fontEncode(dataToEncode) );
}
}
The data string returned by the fontEncode method will create a proper Data Matrix
symbol when printed with the Data Matrix font. To install the font
on an operating system, consult the OS documentation or follow IDAutomation's
font installation
procedures.
Java Encoder Properties and Methods:
- fontEncode() - The method that formats and returns a string of data
formatted to the Data Matrix Font.
- code - This is the value to be encoded.
- encoding - The encoding mode;
valid values are E_ASCII (default), E_C40, E_TEXT or E_BASE256.
- preferredFormat - Sets the preferred
format represented by a number; valid values are from 0 (10X10) to 23 (144X144)
and from 24 (8X18) to 29 (16X48); the default value is -1 which sets this to
automatic.
- processTilde - If true ("Y") the tilde (~) will be
processed.
Install the Font and Encoder for Windows by running the EXE file provided
in the package. Upon execution, it installs TrueType fonts, implementation examples
and registers the ActiveX DLL. To register the DLL manually, perform the following:
(1) copy the DLL to the \System directory; (2) Register the DLL by going to the
command prompt, change to the \system directory, and type the following command:
REGSVR32 "IDAutomationDMATRIX.DLL". After the DLL is installed and registered,
it may be accessed by any application that can retrieve a text string or graphic
object from a COM DLL.When using the COM DLL as a graphic encoder, refer to the
instructions in the
ActiveX Control Manual. When using the COM DLL as a font encoder, the FontEncode
function is used to convert the data to encode into a string, that when combined
with the Data Matrix font, will create a correct barcode. The following is Visual
Basic 6 code that places the result in the "PrintableBarcodeString" variable:
DataToEncode = InputString.Text
Dim DMFontEncoder As DMATRIXLib.Datamatrix
Set DMFontEncoder = New Datamatrix
DMFontEncoder.FontEncode DataToEncode, 0, 0, 0, Printable_string
PrintableBarcodeString = Printable_string
A Visual Basic project example is included with the package. These files are placed
in the destination directory upon installation.
Distributing IDAutomation's Font and Encoder
Note: Redistribution of IDAutomation's fonts or
components requires a Developer License.
When Crystal Reports or Microsoft Access applications are distributed, the
Native Crystal Formula or the
Native Access Encoder provided in this package may
be distributed without any dependencies as the font encoder function along with
the IDAutomationDMatrix font. Other encoders provided such as the ActiveX DLL, .NET
DLL and Java Class Library do not have any dependencies.
The benefits include high scalability with operating system, application and
printer independence, these are best described in IDAutomation's
Font Quality Statement.
Encoding Extended ASCII Characters
It is possible to scan and encode extended characters provided these rules are
followed:
- Encode the data using BASE256. This option encodes ASCII 0 to 255
of the ASCII character set. To encode ASCII 0, the format
~d000 should be used. When encoding over 1024 characters
of data, ASCII 127-160 must also be encoded in the format ~dNNN.
- Scan the data via the serial interface option (data bits have to
be 8N) on a scanner. Normally, keyboard wedges and USB scanners do not support
extended characters above ASCII 128 and they only can scan characters that are
actually on the keyboard. Contact the scanner vendor for more information on
how to do this; some internal settings may have to be modified on the scanner.
Amount of Data that may be Encoded
IDAutomation's Data Matrix product will encode the amount of data specified in
the Data Matrix Formats section. However, in most situations it is difficult to
scan data
over 800 characters. The ActiveX and COM DLL provided have an encoding limitation
of about 800 characters, which is necessary for compatibility with Visual Basic.
The "Structured append" function is also an
option that will allow large amounts of data to be represented as a sequence of
up to 16 symbols. The original data can be reconstructed regardless of the order
of the symbols.
Microsoft Excel Compatibility
Microsoft Excel may be used as a data source for the font; however, it is difficult
to use the Data Matrix font in Excel. To overcome this problem, the Data Matrix
DLL supplied also works as an
ActiveX Control
and may be used in this way when it is not necessary to use a font. To use it in
this manner, see the
ActiveX Control
tutorial as an example.
Some implementations of PostScript fonts can cause a small space to appear between
rows in the symbol. The only way to overcome this issue is to make sure the printing
application is not adding additional line feeds, or in the case of PCL fonts, change
the vertical motion index as indicated below.
When using 12 or 14 point PCL fonts, an adjustment to the vertical motion index
is not usually necessary. However, if other sizes are being used, an adjustment
may be needed to close the gap between rows. To set the vertical motion index, issue
the command before printing with the Data Matrix font. The code for the vertical
motion index command is Escape "<Ec>" + "&" + lowercase L "l" + Number Index + Capital
"C". Use the chart below to find the command for the font size desired. The number
may be adjusted as necessary for the printer.
PCL Font Point Size |
Vertical Motion Index
Command to Use |
10 |
<Ec> &l6.5C |
8 |
<Ec> &l5.2C |
6 |
<Ec> &l3.9C |
In the example above, the <Ec> represents the escape character for the software
used. In DOS Edit, Ec is represented by holding down the CTRL key and pressing the
letter P, Releasing both keys and then press the ESC key.
X axis issues or left margin alignment issues when
using the font
This issue may exist if moving the barcode to the right on the X axis using a
programming language such as Visual Basic. When using the printer.currentX specification
to set the X axis, only the first line of the barcode would print in the new position
and the remaining lines would print at zero (all the way to the left). This is because
the printer.currentX specification is reset every time a return is performed. A
return must be performed to print the font on the new line
The best solution to this problem is to find a command that could move the left
margin so that a new line will return the insertion point to the correct position.
Since Visual Basic does not have a command like this a small piece of code must
be written to set the currentX for each line.
Step 1. Declare and initialize a variable with the desired X position. Example:
my_x = printer.currentX
Step 2. Replace the "Printer.Print OutputString" command with something similar
to the following:
For i = 1 To Len(Output)
out1 = out1 & Mid(Output, i, 1)
If Mid(Output, i, 1) = Chr(10) Then
out1 = Replace(out1, Chr(10), "")
out1 = Replace(out1, Chr(13), "")
Printer.CurrentX = my_x
Printer.Print out1
out1 = ""
End If
Next i
The selected format determines the smallest size of the symbol. If the data encoded
cannot fit in the selected size, a larger symbol will automatically be generated.
Valid values are from -1 (for automatic) and 0 to 23 (144X144) and from 24 (8X18)
to 29 (16X48). The following table contains the size, the best case capacity and
the correction error features of each format:

The data represented in the symbol may be compressed by changing the encoding
mode, if certain text is being encoded. Valid values are 0 for BASE256,
1 for C40, 2 for TEXT and 3 for ASCII.
- 0 - BASE256 is used to encode 8 bit values.
- 1 - C40 is used to encode data that mainly contains numeric and upper
case characters. C40 encodes three alphanumeric data characters into two bytes.
- 2 - TEXT is used to encode data that mainly contains numeric and
lowercase characters. TEXT encodes three alphanumeric data characters into two
bytes.
- 3 - ASCII is used to encode data that mainly contains ASCII characters
(0-127). It encodes one alphanumeric or two numeric characters per byte.
All encoding systems can be used to encode any data; however, encoding binary
data with C40 generates much more overhead (a larger symbol) than with BASE256.
Control Characters and use of the
Tilde
When ProcessTilde is equal to 1 or TRUE, the tilde (~) may be used to recognize
some special characters in the input data. The following possibilities are available:
- ~dNNN: Represents the ASCII character encoded by the 3 digits NNN. For example,
~d065 represents the character 'A'.
- ~1: Represents the character FNC1. When FNC1 appears in the first position
(or in the fifth position of the first symbol of a Structured Append), it will
indicate that the data conforms to the UCC/EAN Application Identifier standard
format.
- ~2: It is used to represent Structured Append.
Structured Append is used to link information from several symbols in a sequence.
The ~2 must be followed by 3 additional bytes. The first 4 bits of the first
byte identify the position of the particular symbol in the sequence. The last
4 bits identify the total number of symbols in the sequence. The second and
third bytes are used as a file identifier and can have a value between 1 and
254 (up to 254*254=64516 identifiers). See the Data Matrix Specification for
more information about this (ISO 16022).
- ~3: This character is only allowed in the first position of the symbol.
It indicates that the data contains commands for the barcode reader.
- ~5 and ~6: These characters are only allowed in the first position of the
symbol. If ~5 is used the header [)> ascii30 ascii05 ascii29
will be transmitted by the barcode reader before the data in the symbol and
the trailer ascii30 ascii04 will be transmitted after the data.
If a ~6 is used, the header [)> ascii30 ascii05 ascii29
will be transmitted by the reader before the data and the trailer ascii30
ascii04 will be transmitted afterwards.
- ~7NNNNNN: Specifies the Extended Channel to be used, where NNNNNN is a value
between and 000000 - 999999. For example: ~7000010 means Extended Channel 10.
Extended channel is used for using character sets other than ASCII. See the
Data Matrix Specification for more information about this (ISO 16022).
The IDAutomation DataMatrix font is named IDAutomationDMatrix, and is included
in several formats including TrueType, PostScript, OpenType and PCL. The IDAutomationDMatrix
font should be printed at 8 points unless it is necessary to create a larger or
smaller symbol.

Using the Data Matrix Encoder for other
purposes such as with Intelligent Positioning Drives.
The data returned from the Data Matrix Encoder may be used for other
purposes such as in using intelligent positioning
drives to stamp codes into metal parts. The images in the characters of the font
are 4 squares stacked on top of each other. The sequence is a binary 0 (0000) (0
being a white space or no impression and 1 being dark space or an impression) at
character "P" to a binary 15 (1111) at character "A". For example, multiple A's
(1111) stacked, create a vertical line of 4 squares.
