Single read special read only code (SS):
The R/W head makes only one attempt to read a
special read only code
.
Enhanced read special read only code (ES):
The R/W head attempts to read a
special read only code
until successful. Only data that
changes is transferred via the interface, i.e. the R/W head transfers data whenever it reads a
new data carrier or whenever it reads a data carrier where there was previously no R/W head
within the detection range.
The status '05h' (read command) is output whenever a data carrier leaves the detection range.
Single program special read only code (SP):
The R/W head makes only one attempt to write a
special read only code
.
Enhanced program special read only code (EP):
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.
