datafield
(D)]
RFWRITE; The RFID Write Tag command.
HEX; Optional parameter to indicate that the
text in
datafield
is in hexadecimal format
and that it will be converted to binary
format.
EPC
m
; Optional parameter to indicate that the
data in
datafield
should be converted to
an EPC number. When this parameter is
used, the HEX option is automatically
enabled and the data field is limited to a
maximum of 14 digits. The AT parameter
is ignored. The tag is then programmed
as follows:
Bits 0 to 1 are programmed with the
EPC value 0 to 3, specified in
m
.
Bits 2 to 57 are programmed with the
hexadecimal characters in the data field
(14 maximum). If the data field has less
than 14 hexadecimal characters, zeros
are assumed for the remaining digits.
Bits 58 to 63 are set to zero.
RF
n
;
L
; Optional parameter to indicate that this
field has dynamic data. Replace
n
with a
number ranging from 1 to 512 to identify
the field number of this RFWRITE field.
Replace
L
with the length of the dynamic
data string. If this option is used, the
datafield
is ignored, and dynamic data
must be entered via the RF command in
the EXECUTE mode. The length of the
dynamic data must be equal to
L
.
LOCK; Optional parameter to write-protect the
data. Currently not supported.
AT
p
;
p
specifies the decimal start position
where data will be written to the tag.
Subsequent bits will be shifted and
previous bits are nulled.
