STX KaR Read Data from RFID Tag
(Direct Mode – Generic Read/Write Interface)
This command instructs the RFID device to read data from the tag and then place 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.
Syntax:
KaRAaaabbbcdee
Where: A - Optional – for data in the ASCII format.
aaa - The number of bytes to read.
bbb - HF - Starting block number (000  maximum block
number, which is dependent upon the
transponder manufacturer).
UHF – Should be 000.
c - Command 1. Reserved. Should be 0.
d - Command 2. Reserved. Should be 0.
ee - Field number in which to place the data (must be 01,
02, 03, etc.) matching the order of Label Formatting
command U.
 The 00 value will send read data to the host with no
printing.

The sample above creates a replaceable text field (01), recalls data
from the RFID tag block zero (reading only one block), and prints
the data in the location specified by the replaceable field. Since
there are two digits per each hex value, replaceable fields should be
twice as long than if using ASCII data (e.g., the character “A” would
be returned as “41”).
