Smoothing Buffer
With the help of the smoothing buffer, the Reader/Writer does not return the communications result
of the RF Tag that has been communicated once as a response to the host device. This reduces the
network load and simplifies the host application processing. This function is enabled when the com-
munications mode is "Repeat".
The number of RF Tags to be accumulated in the buffer is set. The buffered data is cleared when the
command execution request is cleared (the EXE signal turns OFF). Alternatively, when the buffer
size becomes full, the data is overwritten starting from the oldest data.
The smoothing buffer conditions during repeat can be set in the following range.

Precautions for Correct Use
When the number of RF Tags being buffered crosses 65, communications are stopped. Since
communications are resumed when the number of RF Tags being buffered falls below 65, make
sure that the host device acquires the response data from the Reader/Writer without delay.
