2. The range of output level is 18 (approx. 100mW) to 0 (approx. 1mW).
3. The setting range of B-EX700-RFID-U2-EU / US-R is 9-18, but LCD displays 0-18.
4. If you set 0 to 8 out of the setting range in B-EX700-RFID-U2-EU/S-R, the operation is not guaranteed.

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”.

When the obtained gain of an RFID tag is lower than the AGC threshold, the tag is considered as an error
tag even if a data write succeeds.
When the AGC threshold is set to
“0”, all tags are writable.
When this parameter is set to
“8”, for example, tags with the AGC threshold level of 7 or less are considered
as error tags.
The optimum value is different depending on the tag types.
