 Stable Operation
When the Reader/Writer communicates with an RF Tag, it diagnoses the communications leeway and
reports the result. You can check the communications leeway to appropriately install the Reader/Writer
and RF Tags to achieve stable operation of your OMRON RFID System.
You can use communications leeway diagnosis with Reader/Writers with firmware version 2.00 or higher.
For details, refer to Using Communication Diagnostic and the RF Analyzer in Section 6 Functions.
p.129
If you use the RFID System under installation conditions that provide a high communications leeway,
you can reduce communications troubles during system operation and achieve stable line operation.
