• No RF Tag in the Communications Range
When the Reader/Writer does not detect an RF Tag in the communications range, it waits for a
timeout and then returns the communications results (RF Tag missing error).
When the Reader/Writer receives a command from the host device, it automatically detects RF Tags in
the communications range and communicates with them.
When the Reader/Writer is finished communicating with the RF Tag, it sends the response to the host
device and waits for another command. With auto communications, the Reader/Writer automatically
detects RF Tags, so a sensor or other device to detect RF Tags is not necessary. Also, auto communi-
cations will continue indefinitely until a command to stop communications is received from the host
device.
Single-access Operation
The Reader/Writer waits for an RF Tag to enter the communications range and returns the commu-
nications results after it detects an RF Tag. If there is already an RF Tag in the communications
range when the command is executed, the Reader/Writer communicates with the RF Tag.
The timeout setting is disabled for single-access communications.
