Functions

This section describes the functions provided in an RFID Unit.

Function name Description
RF Communications option function This function switches the operation sequence during communications with
an RF Tag.
Communications command function This function reads or writes the memory for a RF Tag on the antenna
communications area.
Write protection function This function prevents the loss of data due to overwriting by specifying the
areas in which it is not possible to write to an RF Tag.
RF Tag service life detection function This function records the number of times data is rewritten to an RF Tag,
and determines the maximum rewrite count.
RF Tag memory error detection function This function detects an error during reading by performing CRC calculation
for the memory of an RF Tag.
RF Tag memory error correction function This function detects an error during reading by performing ECC calculation
for the memory of an RF Tag, and corrects the error to an appropriate value.
Test command function This function checks the margin in communications with an RF Tag, and
measures the surrounding noise.
