Direct Mode - Generic Read/Write Interface
This interface allows the Host Application to send generic commands for RFID operations. These
commands consist of simple read and write operations requiring no knowledge (except data format) of the
tag types being used. They utilize the printer’s database for specific parameters.
STX KaW
Write Data to RFID Tag
This command instructs the RFID device to write data to the tag. It is expected that the tag transponder is
within read/write distance of the RFID programming device otherwise a fault will occur and a warning
message will be displayed.
Syntax:
<STX>KaWAaaabbbbcddd…
Where:
Aaaa
- Optional – for data in ASCII format followed by byte count,
000-999
bbb
- HF- Starting block number, (000 -> Max block number)*
UHF – Should be 000.
c
- Command 1. Reserved for Future (should be 0)
d
- Command 2. Reserved for Future (should be 0)
eee
- Data to be encoded on RFID tag. (HF - Last used block will be
null padded if necessary)
Sample:
<STX>KaW0000054455354[CR]
This example programs the data “TEST” at block zero
*Dependent on transponder manufacturer.
