STX KuJ
Write Data to Gen 2 Tag Section
This command writes a specific block address of a Gen2 tag.
Syntax:
<STX>KuJaaabbb<data>
Where:
aaa
- Block address number, where: 000 is kill/access section; 001
is EPC section; 002 is Tag ID; or, 003 is user memory
bbb
- Data offset in word length
<data>
- Hexadecimal data, must be length of multiples of 4
Sample:
<STX>KuJ001002112233445566778899AABBCC
This example writes data “112233445566778899AABBCC” to block address 1 at offset word 2,
which is the EPC data.
STX KuI
Send Inventory (Alien only)
This command instructs the RFID device to read data from the tag and return it to the host. This is
a high level command that uses collision avoidance.
Note: CRC validation is performed, but the CRC is not included in the response (nor is the kill / lock
code).
Syntax:
<STX>KuI<CR>
Printer response:
The data will be output as 16 hex bytes for a 64-bit tag, and 24 hex bytes for
a 96-bit tag.
STX KuG
Send Tag ID with Global Scroll (Alien only)
This command instructs the RFID device to read data from the tag and return it to the host. The
reader sends GLOBALSCROLL air interface. Data is reported regardless of CRC verification.
Syntax:
<STX>KuG<CR>
Parameter 0 – Tag Decode Status:
0x00
= Good ID
0x01
= No Tag
0x02
= Collision
0x03
= CRC Error
Parameter 1 – Antenna Number:
0x00
(always)
Parameter 2 – Tag Data Length, with CRC and kill/lock codes.
0x0A
= 64-Bit Tag
0x0E
= 96-Bit Tag
Parameter 3: CRC byte one
Parameter 4: CRC byte two
Printer response:
Parameter 5 thru (Tag Data 2): Tag Data, MSB to LSB
Note: Data response includes Parameters 2, 3, and 4 only with a ‘Good ID’ (Parameter 0) decode
status.
