Single write fixcode (SX)
Command:
Response:
The R/W head makes only one attempt to write a read only code.
Type IDC-...-1K tags can be programmed in such a way that they are compatible
with the type ICC-... read only carriers. This programming occupies the first 8
bytes in the tag. The read/write commands can be used to access the remaining
memory.
