Symptom

Extra Characters when encoding 96bit, 128bit, or 240bit  EPC (class 1) GEN 2 tags with ZebraDesigner Labeling Software

Applies To

Zebra RFID Printers using ZebraDesigner Labeling Software

Cause or Overview

Zebra Designer supports encoding 96bit, 128bit, or 240bit  EPC (class 1) GEN 2 tags.

When encoding EPC data you must enter the required number of characters to encode the selected data size of the EPC bank.  i.e. If you choose a 96bit EPC tag, then you must send 96 bits of data. If you send less than the 96 bits of data in this case, the printer will pad the rest of the data in the EPC bank with zero's.

 

Solution

Zebra Designer will tell you the correct number of characters when using fixed data.

96 bits = 12 ASCII Characters or 24 HEX Characters

128 bit = 16 ASCII Characters or 32 HEX Characters 

240 bits = 30 ASCII Characters or 64 HEX Characters

Enter the correct number of characters to avoid this problem.
