2.9.14 AGC Threshold for Data Write Setting

This parameter is to set the AGC threshold for data write.

When the Q value is set to 1 or greater, 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.

The optimum value differs depending on the tag type. (For details, refer to Section 8 of Option Installation Manual.)

Difference between the AGC threshold and the AGC threshold for data write

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.

Set an AGC threshold for data write with the [FEED] or [RESTART] key, if necessary.

When “WT AGC” is displayed, press the [PAUSE] key.
