Section 2 Using Multi-Reader/Writer Operation
3. Slave Reader/Writer No. 1 will communicate with the RF Tag using the Once communications option.
Here, if RF Tag communications end normally, the Reader/Writer will return a response to the host
device and processing is repeated from step 2. If an RF Tag tag missing error is detected, processing
will be continued in order by Slave No. 2 and then by Slave No. 3.
4. When communications have been completed for all of the Slave Reader/Writers, the operation is
repeated from step 2.
In Field Extension Mode, the Reader/Writers do not simultaneously perform communications. The Reader/Writers
individually perform communications on a time sharing basis.
