UHF RFID System V780-series Reader/Writer User’s Manual (Z389)
The processing of communications with RF Tags depends on the RF communications mode that is
specified in the Reader/Writer.
The setting of the communications mode is effective immediately after it is changed. It is saved in inter-
nal memory in the Reader/Writer even after the power supply is turned OFF.
The Reader/Writer communicates with an RF Tag when it receives a command from the host device.
When the Reader/Writer is finished communicating with the RF Tag, it returns the communications
results to the host device and waits for another command.
If there is no RF Tag in the communications range when the Reader/Writer executes the command, an
RF Tag missing error will occur. It is therefore necessary to use a sensor or other device to detect the
presence of an RF Tag before a command is executed.
