When the Q value is set to 1 or above, the AGC threshold for data write becomes effective.
When the obtained gain of an RFID tag is lower than the AGC threshold for data write, a data write operation
is not performed. In other words, setting an AGC threshold for data write enables writing data only to a tag
placed just above the antenna.
Supposing that the gain of a tag just above the antenna is 14 and that of a tag off the antenna is 7, setting
the threshold to 11 (a value between 8 and 14) enables the printer to write data only to the tag just above the
antenna.
When the threshold is set to 0, a data write operation is performed regardless of the gain of a tag.
Both of the AGC threshold and the AGC threshold for data write are used to determine whether a tag is
defective or not, but the timing of a gain measurement is different. In the case of the AGC threshold, this is
performed after data is written to a tag. On the contrary, when the AGC threshold for data write is effective a
measurement is performed before data is written. And if a gain value is lower than the threshold, a data write
operation is not performed.
The optimum value differs depending on the tag type.
Actually, the problem of reading multiple tags at the same time does not occur with most RFID tag types. It
is not necessary to change the default setting of
“0”.
Note: This is effective only for the following modules:

When the Q value is set to 1 or above, the AGC threshold lower limit for retry becomes effective.
In the case the printer could not find any tag whose gain is over the AGC threshold for data write, the AGC
threshold is lowered to the highest gain of the detected tags whose gains are over the AGC threshold lower
limit for retry specified with this parameter.
Example 1
AGC threshold for data write: 11
Lower limit for retry: 9
Detected tag’s gain: 10
