S0 Factory default setting.
In this setting, the reader communicates with all tags existing
in the communication field whenever a command is executed.
S1/S2/S3 In this setting, the reader communicates with un-read tags (it
ignores once-read tags.)
If S1 is set, tag refreshes its S1 flag when a specified time has
passed after flag setting (after communication transaction)
regardless of whether tag energized or not. It means that the
tags are read repeatedly in a certain interval.
If S2 or S3 is set, tag refreshes its S2 or S3 flag when a
specified time has passed after tag energizing stopped. It
means that the tag is not re-read unless the tag stays out of
the communication field for the specified time.
S2 Factory default setting.
In this setting, the reader communicates with new-detected
tags existing in the communication field during the command
execution.
S0 When there is a tag the reader can not read because of flag
conflict with other readers, this setting enables the reader to
read the tag.
S1/S3 If another reader set in the previous process line uses S2 flag,
the reader same flag may encounter the flag conflict. S1 and
S3 flags are used to avoid this conflict.
Setting S3 provides same operation as S2 setting.
If S1 is set, tag refreshes its S1 flag when a specified time has
passed after flag setting (after communication transaction)
regardless of whether tag energized or not. It means that the
tags are read repeatedly in a certain interval.
