Operation of the "Auto" Communications Mode
• If the RF Tag completes normally in any of the Reader/Writers in single-access
The master Reader/Writer switches the control of itself and the Slave Reader/Writers in time divi-
sion, waits for the entrance of the RF Tags into any of the communications range, and will return the
communications result after detection.
• If the RF Tag completes normally in any of the Reader/Writers in multiaccess
The master Reader/Writer switches the control of itself and the Reader/Writers in time division, waits
for the entrance of the RF Tags into any of the communications range, and communications will start
if even one RF Tag is detected. Then, if the Reader/Writer detects more RF Tags within the timeout
time from the start of communications, it waits for the timeout and then returns the communications
results.
