5) FIFO Continue
After waiting for the Tag to approach, then communicates with the Tag
and transmits a response. After transmission is completed, Tag will
become inoperative. After transmitting a response, the Reader Writer will
await Tag to approach again if it receives [ACK], and CONTINUE UNTIL
THE READER WRITER RECEIVES A STOP COMMAND. When
communicating with the Tag, THERE MUST BE ONLY ONE ACTIVE
TAG within the transmission area.
♦ Operation Sequence
Upon receiving the command, the Reader Writer awaits Tag to approach.
When Tag is detected, the Reader Writer executes command and
transmits a response. Afterwards, when [ACK] is received, the Reader
Writer repeats the same operation. Once process is executed on a Tag,
the Tag becomes inoperative, and thus a Tag will only be processed once.
When the Reader Writer receives a STOP command, processing will
stop.
