Field
UID_LNG:
Is a optional parameter and depends on the setting of UID_LF (see MODE). UID_LNG de-
fines the length of the following UID field.
UID:
Read-only serial number of the Transponder. The UID is required only in the addressed
mode.
BANK:
Memory bank of the Transponder which will be accessed by the Reader

Function
A_FLAG
0 0 0 0 0 BANK_NR
BANK_NR:
In case of ISO18000-3M3 Transponder BANK_NR is defined as follows:
b00 reserved
b01 EPC
memory
bank
b10
TID memory bank
b11
User memory bank
A_FLAG:
Indicates whether the reader tries to read a ISO18000-3M3 tag in Secured State.
If A_FLAG is set the protocol contains the access password.
A_FLAG:
b0
no access password in protocol
b1
access password and access password length in protocol. Reader ex-
ecute access command
A_PW_LNG:
Length of Access Password.
A_PW:
Access password which is used to access to the secured state of the Tag.
DB-ADR:
First block number to be read. Depending on EXT_ADR First block can be any value be-
tween 0 and 255 or 0 and 65535.
DB-N:
Number of data blocks to be written to the Transponder, starting at DB-ADR.
The maximum number of DB-N, depends on DB-Size and the interface receiver buffer
size RX-BUF. The maximum number of DB-N is:
(RX-BUF - 20 )/(DB-Size) e.g. Block size 4 (DB-N = (280 – 20) / 4 = 65)
