Field Valid Inputs Meaning
HF:
Lock after write, where:
x = 0 – Use printer setup to determine if lock is performed.
x = 1 – Lock after write.
yy = Not Used
UHF EPC Gen2:
Lock after write, where:
x = 0 – Use printer setup to determine if lock is performed.
x = 1 – Lock after write.
yy = Lock state where “01”is for permalock, “10” for pwd-

eee xyy
UHF other tag types:
Not Used, should be 000
HF:
Starting block number to write.
UHF EPC Gen2:
Block address where “0001” is EPC data, “0002” is Tag ID or
“0003” is user memory. Using “0000” is for EPC data also (for
backwards compatibility).
ffff
0000 – 9998
UHF other tag types:
Not Used, should be 0000
HF:
Not Used, should be 0000
UHF EPC Gen2:
Data word offset – currently only used for read operation
gggg 0000
UHF other tag types:
Not Used, should be 0000
hhhh
Four-digit decimal data
byte count.
Number of bytes to follow (to include all bytes that follow until
the end of the data).
 Note: UHF: Data length must be 8 or 12 for EPC, 8 for Tag ID or
multiples of 2 for user memory sections
jj…j
Valid ASCII character
string followed by a
termination character. Data to write to the tag.
