In the case multiple RFID tags are read at the same time, this menu is useful to focus on a target tag.
Set the Q value to “1” or above (2 is recommended). Q value “0” causes the tags to interfere with each
other and disables proper data write.
When the Q value is set, set an AGC threshold for data write and an AGC threshold lower limit for retry,
also. Setting all these values enables writing data to a tag placed just above the antenna.
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:
・ B-EX706-RFID-U4-R
・ B-EX706-RFID-U4-EU/US/AU-R
