STX KuT
Send Tag ID (Alien only)
This command instructs the RFID device to read data from the tag and return it to the host. This is
a low level command that issues an air interface command to acquire one tag ID. There is no
collision avoidance used. A CRC validation is performed on the data; however, the CRC data is
not returned.
Syntax:
<STX>KuT<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 (only included if ‘Good’ ID status):
0x08
= 64-Bit Tag
0x0C
= 96-Bit Tag
Printer response:
Parameter 3 thru (Tag Data 2), (only included if ‘Good’ ID status):
Tag Data, MSB to LSB.
STX KuV
Send Tag ID with Verify (Alien only)
This command instructs the RFID device to send a VERIFY air interface command. 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
(only
included if ‘Good’ ID status):
0x0C
= 64-Bit Tag
0x10
= 96-Bit Tag
Printer response:
Parameter 3: CRC byte one
Parameter 4: CRC byte two
Parameter 5 thru (Tag Data Length): Tag Data, MSB to LSB
Param Tag Data 1: Kill Code
Param Tag Data 2: Lock Code
