Example 3:
The following format reads a UHF Gen2 tag with data from address 1, offset 2nd word (EPC data),
Tag ID from address 2, and user data from address 3. Note that the length of the data in the record
determines how much data is read.
<STX>L
D11
1W1x0000000010002xxxxxxxxxxxxxxxxxxxxxxxx
1W1x0000000020000xxxxxxxxxxxxxxxx
1W1x0000000030000xxxxxxxxxxxxxxxx
E
With Option Feedback enabled, the format above would return data such as:
<R;C;03;03;0002:0001;112233445566778899AABBCC;E20060010128FF33;11112222333
34444>
Where, "112233445566778899AABBCC" is the EPC data, "E20060010128FF33" is the Tag ID and
"1111222233334444" is the user memory data. See Option Feedback Mode (<STX>KcOF) for more
information on the response format.
WX / W1X: RFID with Byte Count Specifier
Specified Length – The upper case X identifies an RFID data string with a string 4-digit length
specifier. The length specifier allows values 0x00 through 0xFF to be included within the data
strings without conflicting with the DPL format record terminators. The four-digit decimal data byte
count immediately follows the four-digit column position field. This value includes all of the data
following the byte count field, but does not include itself.
Syntax for RFID with Byte Count Specifier (spaces shown for readability):
