Starting command repetition
You have the option of using command repetition with or without transfer of the command.
The various procedures are described below.
Sequence of the repeat command with simultaneous command transfer:
1. If applicable, enable presence mode (with RF61xR/RF68xR).
2. Start the command using the input parameter "EXECUTE" while "RPTCMD" is set at the
same time.
The command is processed and the result transferred to the Ident profile.
The Repeat command is activated on the reader.
3. The reader confirms activation with the output parameter "RPTACT" of the Ident profile.
The confirmation is made only after the first command has been executed.
The reader executes the command automatically as soon as a transponder is identified in
the antenna field.
If the reader does not support the Repeat command, "RPTACT" remains inactive. If
"EXECUTE" is nevertheless set, the error "0xE7FE0900" is output after a timeout of 10
seconds.
4. You can read out the individual results by repeatedly setting the "EXECUTE" input
parameter.
