Section 2 Using Multi-Reader/Writer Operation
 When the RF Tag Communications Option of the Master Reader/Writer Is Set to
Repeat
1. Send a READ DATA command from the host device to the Master Reader/Writer.
2. The Master Reader/Writer 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 missing error is detected, processing
proceeds to step 3.
