6 - 54 UHF RFID System V780-series Reader/Writer User’s Manual (Z389)
The Focus Mode of the Reader/Writer uses a target level index to determine the RF Tag that is posi-
tioned in front of the Reader/Writer.
When the Reader/Writer receives a command from the host device, it communicates with the RF
Tag that has the highest target level. The target levels will change according to the positions and
travel speeds of the RF Tags passing through the communications range. The distance between RF
Tags also has some influence on the target levels of those RF Tags.
You can use a focus monitor to check and adjust differentiation of target RF Tags and achieve more
stable RFID system operation.
