Bit Field
NOTE: 1. Multiple RFRTAG commands are allowed in the same form but the same DFn field cannot be
defined multiple times.
2. The DF field length is restricted to 64 bits for binary or decimal format and must be a multiple of
8 bits. The sum of all field lengths must be equal to the tag size.
3. The first field always start at the MSB bit. The bit length of a field dictates the start bit of the next
field, etc. As a result, DF fields will not overlap each other.
4. RFRTAG does not allow incremental fields (with the "I" prefix).
5. 432 IGP dots in the ~CREATE line specifies a 6 inch label. 6 inches = 432 (IGP dots)/72 (dpi)
Use 144 for 2 inch labels and 288 for 4 inch labels.

When the UNLOCKn option is used to unlock any memory bank, which
at the same is programmed to read the tag, the operation UNLOCKn
will not unlock ACS memory area. The passcode (n) can also be in
dynamic format. For dynamic format, enter LOCK<DFn>, where DFn is
the dynamic field defined in EXECUTE mode.
format is the optional parameter to specify the format for the
passcode data. Enter B for binary, D for decimal, and H for
hexadecimal. The default is decimal if format is not specified.
Specifies which tag logical memory area that this command will be
applied. If omitted, it defaults to the EPC memory area. Other areas
include Identification, User Data, Access area, and Kill area. Enter
one of the following values:
'EPC' – EPC 12 bytes data area (default)
'TID' – Tag identification 8 bytes area
'USR' – User 32 bytes area
'ACS' – 4 bytes access code area
'KIL' – 4 bytes kill code area
'PC' – 2 bytes PC code area (Gen 2 tags only)
A line description of a bit field; must have one of the following syntax
formats:
length;DFn;format
length A decimal number specifying the bit length of a field
within a tag. The maximum length is 64 bits for
binary or decimal format. For hexadecimal format,
the bit length can be up to the maximum bit length
specified for the corresponding memory bank.
DFn Indicate dynamic data field to store the read result.
Replace n with a number ranging from 1 to 512 to
identify the field number of this particular field.
format A letter specifying the representation
format of the field data.
B – binary, D – decimal,
H – hexadecimal
