4.23 RFID MODULE (B-SX704-RFID-U2-AU-R)
4-178
4.23.5 AGC Threshold Setting
The B-SX704-RFID-U2-AU-R chooses a tag to write data on according to a radio intensity of RFID tags (AGC
value).
An AGC threshold value has been set to 0 (00h) as factory default, but it may be necessary to change this value
according to the tag type to be used.
When the factory default threshold value is not proper for the tag type used, follow the procedure below to
configure the following settings.
As the changes are stored in the internal memory, they are retained after the printer power is turned off and on
again. When the tag type is changed or data write cannot be operated properly, perform the setting again.
Step 1. Load an RFID tag embedded media in the printer.
Step 2. Follow the procedure below to measure the radio intensity of the tags.
1) Place the media so that an RFID tag (IC chip) is positioned above the Antenna, and close the Top
Cover.
Note
: If an RFID tag is not positioned above the Antenna while the Print Head is at a print start
position, use @003 command to adjust the media position so that an RFID tag is positioned
above the Antenna. For detail of the command, refer to the External Equipment Interface
Specification (Printer Command Manual).

WT AGC 0
[PAUSE]
AGC threshold for data write setting menu is displayed.
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 thresholdfor data write, data
write 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.
The optimum value differs depending on the tag type.
(For details, refer to Section 4.23.5 AGC Threshold Setting.)
Set an AGC threshold for data write with the

or
[RESTART]
key, if necessary.

AGC threshold lower limit for retry setting menu is displayed.
When the Q value is set to 1 or greater, the AGC threshold lower limit for retry becomes
effective.
When there are tags of which AGC values fall within the range between the AGC threshold for
data write and the lower limit, the printer retries data write for a tag with the highest AGC value
among those tags. When printer retries data write, that value is then used as an AGC
threshold.
The optimum value differs depending on the tag type.
(For details, refer to Section 4.23.5 AGC Threshold Setting.)
Set the lower limit for retry with the

The LCD message returns to ”<10>RFID”.
Now, the RFID module settings are completed. If data write to RFID tags cannot be properly
performed, refer to Section 4.23.5.
