STX KaW Write Data to RFID Tag
(Direct Mode – Generic Read/Write Interface)

tag transponder will be within the read / write distance of the RFID programming device;
otherwise, a warning will occur and a warning message (Read / Write Fail) will be
displayed.
Syntax:
<STX>KaWAaaabbbcdee…e<CR>
Where:
Aaaa
- Optional – for data in the ASCII format, followed by
the byte count (000-999).
bbb

UHF Hexadecimal formats must be 16 or 24
character pairs.
Sample:
<STX>KaW0000054455354[CR]
The sample above writes the data “TEST” at block zero.
