STX KtR Read Data from RFID Tag
(Direct Mode – HF [13.56 MHz] ISO15693 Tag Interface)
This command instructs the RFID device to read data from the tag and then put that
data into a replaceable field. It is expected that the tag transponder will be within the
read / write distance of the RFID programming device; otherwise, “Void” will be printed
in the text or bar code label field(s).
Syntax:
<STX>KtRUn
1…
n
16
Haaabbbcdee<CR>
Un
1
…n
16
-
(Optional) Where n
1
…n
16
is the Unique Identifier (UID)
in hexadecimal format. Must be sixteen characters
long.
H
-
(Optional) Hexadecimal data – “H” may be added
directly after “R” to return a two character hex value of
the data. Since there are two digits per hex value,
replaceable fields should be twice as long than if using
ASCII data (e.g., the character “A” would be returned
as “41”).
aaa
-
Starting block number (000 maximum block
number). Transponder dependent.
bbb
-
The number of blocks to read (001 maximum block
number). Transponder dependent.
c
-
The number of retry attempts, 0-9.
d
-
Reserved. Should be 0.
Where:
ee
-
Field number in which to place the data (must be 01,
02, 03, etc.) matching the order of Label Formatting
command, U.
A 00 value will send tag data to the host with no printing.
Sample:
<STX>L
1911A1802000010TEXT
U
X
<STX>KtRUE00700ABCDEF1234H0000015001
<STX>G
The sample above creates a replaceable text field (01), recalls
data from the RFID tag block zero (reading only one block, which
is attempted nine times), and prints the data in the location
specified by replaceable field.
When using addressed commands and the tag with the specified UID cannot be found, a
standard RFID read/write fault will be issued.
