Example 1: The following example encodes an HF tag , starting at block 001, with
“Datamax writes RFID best”:
<STX>L
D11<CR>
2W1x0000000010000446174616D61782077726974657320524649442062657374<CR>
E
Example 2: The following format encodes a UHF Gen2 tag with EPC data
“112233445566778899AABBCC” and user memory data “1111222233334444”.
<STX>L
D11
2W1x0000000010000112233445566778899AABBCC
2W1x00000000300001111222233334444
E
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.
