Advanced Access Tab
The Advanced Access tab has three general control areas: Read, Write, and Lock. All three
operations require you to specify the bank of tag memory to access (Reserved, EPC, TID, and
User). When reading and writing, you must specify the offset into that bank of memory where you
would like to access. The reading operation also requires you to specify the length of the data to
read. Both the offset and length parameters are measured in words (1 word = 2 bytes = 16 bits).
Three main areas in Advanced Access:
Read, Write, and Lock. Each requires
you to specify a memory bank.
Note in this read that the tag’s actual
EPC code (FEEDFACEBEEF…) is two
words offset into the EPC bank.
You must enter the hex data to write in
the field. The helpful popup keypad
makes entering hex data easy.
Verifying the success of the write, with
another read (of just the EPC code).
