1.4 Adjusting the RFID Tag Detection Sensitivity
This section describes how to adjust the RFID tag detection sensitivity.
Set the reading distance and reading time for RFID tags with
Reading Distance
and
Reading Time
under the
Tag
Read Settings
on the
RFID Reader Settings
tab in the KW RFID Configurator.
•
For
Reading Distance
, specify the distance from the RFID tag to the KW2D Series Smart RFID Reader as a value
between 7 (near) and 0 (far). This distance is shown as the RSSI (received signal strength) value in eight steps.
•
For
Reading Time
, specify the response time from when the RFID tag is held up to the KW2D Series Smart RFID
Reader as a value between 300 milliseconds (quick) and 3000 milliseconds (slow). The value can be set in ten steps
in increments of 300 milliseconds.
The response time has a margin of error of -300 milliseconds. This means the response time is detected between
300 to 600 milliseconds when 600 milliseconds is specified.
Increase the response time to prevent detection of RFID tags when they mistakenly touch the KW2D Series Smart
RFID Reader. For details, refer to Chapter 6 "Tag Read Settings" on page 6-12
•
When using a KW2D Series Smart RFID Reader with a tag holder, the tag may be detected before the tag is
placed in the holder. Set the reading distance to RSSI value: 6 or 7 (near) to prevent detection of the tag
before it is placed in the holder.
•
The KW2D Smart RFID Reader is in "detection mode (detecting RFID tag)" from the time the tag is held up
until the tag detection is confirmed. For details, refer to "Detecting an RFID tag" on page 5-3.
