2.9 RFID Module Setting
2-83
2.9.11 RFID Wireless Power Level Setting
With this parameter, it is possible to adjust the level of radio frequency output from the RFID module.
The optimum level differs depending on the tag types and module types.
First, try issuing RFID tags with the default setting. If an error frequently occurs, adjust the output level.
When “POWER LEVE” is displayed, press the [PAUSE] key. (Default is 18.)
Use the [FEED] or [RESTART] key to select a desired option. (Range: 9 to 18)
After selecting the adjustment value, press the [PAUSE] key. The display returns to “<10>RFID”.
NOTE: The optimal value is different depending on the tags used. Usually it is not necessary to change
this value but changing the value sometimes can increase the number of successful read/write
times.
2.9.12 RFID AGC Threshold
This parameter is to set a threshold used to identify an RFID tag is defective or not.
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 set to “8”, for example, only tags with the AGC threshold level of 9 or greater are writable. The optimum
value is different depending on the tag types. The factory default is 0.
Set an AGC threshold with the [FEED] or [RESTART] key.
When “AGC THRESHOLD” is displayed, press the [PAUSE] key.
Use the [FEED] or [RESTART] key to select a desired option. (Range: 0 to 15)
After selecting the adjustment value, press the [PAUSE] key.
