Commands
Initialize data carrier (SI):
This command allows conventional reading and writing of IDC-...-1K read/write tags that were
configured using the
EP
or
SP
commands.
Extended commands for type IQC-... read/write tags.
Single write words with lock (SL)
This command is the same as a normal write command. The data is write-protected at the end
of the write process, provided the data carriers offer this function.
This applies for 13.56 MHz data carriers of the type 21, 22, 24, 33 and 35 as well as for LF data
carriers IDC-
…
-1K. Write protection is only activated for memory blocks involved in the write
process. Data can continue to be written to all other memory blocks.
The R/W head makes one attempt to write <WordNum> 32-bit words from the address
<WordAddr>.
Enhanced write words with lock (EL)
This command is the same as a normal write command. The data is write-protected at the end
of the write process, provided the data carriers offer this function.
This applies for 13.56 MHz data carriers of the type 21, 22, 24, 33 and 35 as well as for LF data
carriers IDC-
…
-1K. Write protection is only activated for memory blocks involved in the write
process. Data can continue to be written to all other memory blocks.
The R/W head repeatedly attempts until successful to write <WordNum> 32-bit words from the
address <WordAddr>. After each successful write, the head sends the response and then
switches to continuous reading. Then the R/W head reads the same data carrier until it has left
the detection range or a new data carrier appears within the detection range. The command
then starts again with write attempts.
The status '05h' is only output when a data carrier leaves the detection range or is not yet within
the detection range. If two data carriers enter the read range one immediately after the other,
the status '05' is not issued between the two readings.
Extended commands for IQH2-... read/write heads
