will be attached beginning at address 20h, and if the Tag implements Extended Protocol Control (XPC) then either
one or two XPC word(s) beginning at address 210h.
TID memory
shall contain an 8-bit ISO/IEC 15963 allocation class identifier at memory locations 00h to
07h. TID memory shall contain sufficient identifying information above 07h for an Interrogator to uniquely
identify the custom commands and/or optional features that a Tag supports.
User memory
is optional. This area of different manufacturers is different. There is no user area in G2 tag of
Inpinj Company. There are 28 words in Philips Company.
Can write protect in four distinct banks. It means this memory is never writeable or not writeable under the
non-safe state; only password area can set unreadable.
B.
18000-6B TAG
6B tag has a memory space, the minimum 8 bytes (byte 0- 7) is UID of the tag, and can't be rewritten.
Following byte all can be rewritten, can be locked too, but once locking, can't rewrite and unblock again.
8. DETAILED DESCRIPTION OF OPERATION COMMAND
8.1 COMMAND OVERVIEV
The reader supports three kinds of command, one kind is the ISO/IEC 18000-6 protocol command, another
kind is reader-defined command, and also one kind is the transparent command.
If the host input of the command is an unrecognized command, such as the command does not support, or
CRC error in the command, then the return value is as follows:
Len
Adr
reCmd
Status
CRC-16
0x05
0xXX
0x00
0xFE
LSB
MSB
If the length of command operands doesn’t conform to the command request, the return value is as follows:
Len
Adr
reCmd
Status
CRC-16
0x05
0xXX
0xXX
0xFD
LSB
MSB
Two kinds of command reader cannot respond:
1. The reader’s address error.
2. The command is incomplete, namely the command
Len
is longer than the actual command length.
8.2 EPC C1G2 COMMAND
8.2.1 Inventory
The command function is used to inventory tags in the effective field and get their EPC or TID values. The
reader executes an
Inventory
command and gets tag’s EPC before any other operation.
The user may accord need to establish this command the first biggest running time (Inventory scan time),
before the command enquires. The reader completes command execution in inventory ScanTime (not including
host sending data time) except inventory command after receiving host command and returns the results.
The default value is 0x0A (corresponding to 10*100ms=1s). The value range is 0x03~0xFF (corresponding to
