Gen 2 memory bank operation parameters (can be omitted)
u: User Memory HEX
v: User Memory Ascii
o: AFI code
m: Locking
k: kill code
a: access code
p: password code
Specify numeric string to write to USER area in hexadecimals.
Specified digits must be multiples of 4.
This can be specified in the range of 4 to 128 digits, but the maximum
number of digits depends on the used tag.
You may also use the space, tab, line feed in data separator, but these
codes will be skipped.
Specify numeric string to write to USER area in ASCII data. It is
necessary to have data area and data size information separated with
a comma before the data. For example in specifying a data size as 16,
specify as follows:
V:16,abcd...
Specified digits must be multiples of 2.
This can be specified in the range of 2 to 64 digits, but the maximum
number of digits depends on the used tag.
Application Family Identifier. Specify a hexadecimal number from 0H to
1FFH. To write as AFI, specify the ninth bit (MSB) as 1.
5-digit binary number Set the bit of the bank to be locked as 1.
If you specify the access code, it results in a "password lock", and if
you omit the access code, it results in a "permanent lock".
Bit Section to be locked
bit0 (LSB) EPCdata
bit1 KillCode
bit2 AccessCode
bit3 TIDdata
bit4 (MSB) UserMemory
Example: If only the EPCdata area is locked "m: 00001"
8-digit HEX code Used when writing the kill code.
Specify other than "00000000" in an eight-digit HEX number sequence
configured by numbers from 0 to 9, and alphabets from A to F. The
purpose of this parameter is only to write the kill code. You cannot kill
the tag actually.
This is an eight-digit number sequence specified when applying the
password lock.
You can use an eight-digit HEX number sequence configured by
numbers from 0 to 9, and alphabets from A to F. To apply the
password lock, specify other than "00000000". If you omit this
parameter, and specify m: Locking, a permanent lock is applied on
the specified area.
This is an eight-digit number sequence used for rewriting the tags on
which a password lock has already been applied.
It is an eight-digit HEX number sequence configured by numbers from
0 to 9, and alphabets from A to F that is used when writing in a tag on
which a password lock has been applied. Specify the same number
sequence as the access code used at the time of locking.
By specifying a number sequence same as the access code specified
at the time of password lock in the "password code", and specifying
"00000000" in the "access code", the tag on which a password lock
has been applied can be returned to an open state.
