Edifact Encoding Scheme
X12 encoding scheme includes 63 ASCII values (values from 32 to 94) plus an Unlatch
character (binary 011111) to return to ASCII encoding. Edifact encoding encodes four data
characters in three codewords.

Barcode ID
The printer is able to print two different unique Data Matrix barcodes per format and this
parameter is used to select which formatting data is being used. The valid parameters are a
0 or a 1. To printer the proper barcode, the CGN field must also reflect a 0 or 1 to match the
Barcode ID field. The CGN default is a 0 so if only one barcode is present and the Barcode
ID is a 0, nothing has to be entered as the CGN.
Data
Data to be converted to 2D Data Matrix Barcode, maximum number of characters supported
in the printer implementation is 1000.
