Enhanced program special fixcode (EP)
Command:
Response:
The R/W head attempts to write a
special read only code
until successful. 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' (read/write command) is output when the data carrier leaves the
detection range or if the data carrier is not yet within the detection range when the
command is executed.
If two data carriers enter the read range one immediately after the other, the status
'05h' is not issued between the two readings.
