Example 2 •The following command specifies that there are 64 bits used with eight 8-bit
fields.
^RB64,8,8,8,8,8,8,8,8^FS
The ZPL code to encode a tag with this format would look like this:
^RFW,E^FD1.123.160.200.249.6.1.0^FS
When writing to the tag, each set of data is written in its respective 8-bit field.
Example 3 •This example uses the SGTIN-64 standard, which defines 64-bit structure in the
following way:
The ZPL code to encode a tag with this format would look like this:
^XA
^RB64,2,3,14,20,25
^RFW,E^FD0,3,12345,544332,22335221^FS
^XZ
These commands would put
• 0 in the header
• 3 as the filter value
• 12345 as the company prefix
• 544332 as the item reference
• 22335221 as the serial number
To read this EPC data and print the results on the label, you would use the following code:
^XA
^RB64,2,3,14,20,25
^FO50,50^A0N,40^FN0^FS
^FN0^RFR,E^FS
^XZ
The resulting label would look like this:
Header Filter Value
Company
Prefix Index
Item Reference Serial Number
SGTIN-64 2 bits 3 bits 14 bits 20 bits 25 bits
10
(binary value)
8
