In this example, the Asset Reference field obtains its value from the keyboard.

1.  Load (or design) the label or tag that you want to use.  (Refer to Creating RFID Smart Labels in this chapter, if needed.) 

2.  Add a variable text field, AssetRef.  Leave its Data Source set to Keyboard.  For the Printing Field, select No.

3.  Double click on the RFID antenna icon.  (Alternatively, select and then right click on the RFID antenna icon.  From the popup menu, select Edit Data Source.)

4.  From the Data Source dialog, select Block Configuration and then click on the Configure button.  This launches the Block Configuration dialog.

5.  Set the Tag Type to UHF 96 bit Class 1. 

Note: In Loftware RFID versions before 8.3, Loftware programmed the RFID field as one unit and did not consider block composition.  Nonetheless, it was designed to produce an EPC that uniquely identified the tagged item.  Because block structure was not utilized, most of the settings for the RFID field were selected or assigned from its property box.  The RFID field’s properties that could be set from its properties box included its Tag Type, its EPC Encoding Type, its Filter Value, etc.  In addition, any field needed to pass a value to the RFID field had to have its RFID Link Field property set to ‘Yes’ and its RFID Link Field Name property set to a field from which the value was derived.

Beginning with Version 8.3, user-programmable blocks became accessible.

6.  Set the Data Source for the EPC block to EPC.  Click on its ellipsis button in the Data column to display the EPC Configuration dialog.

7.  Set the EPC Encoding Type to GIAI-96 ALT.

Refer to the section Global Individual Asset Identifier (GIAI) section for a description of the fields on this dialog.

8.  For the Filter Value, set the Data Source to Choice and its Data value to 0.

9.  For the Company Prefix, choose the Fixed Data Source and type in 12345 for its Data value.  You may substitute your own Company Prefix here, if you wish.

10. For the Asset Reference field, set the data Source to Field.  For its Data value, select AssetRef. 

11. Click OK from each of the dialogs to return to the design area.
