Omron V680S Series User Manual

Section 2 Functions
 Repeat
When the Reader/Writer receives a command execution request from the host device, it automatically
detects RF Tags in the communications field and communicates with them. This process is repeated
until the execution request is cleared.
Communications are not performed for RF Tags that have returned communications results to the host
device until the Reader/Writer has to communicate with another RF Tags.
You can use this specification to perform communications with RF Tags in order as they move past the
Reader/Writer. However, if there is more than one RF Tag in the communications field of the Antenna
at the same time, normal communications will not be possible. Make sure that there is never more than
one RF Tag in the communications field of the Antenna at the same time.
