Notes:
•
Reader detects antenna connection by measuring the Return Loss of RF ports.
•
Reader stops tag operation if Return Loss is above the threshold.
•
User can turn it off by setting the threshold to 0.
If antenna is not connected, Reader will stop to operate tags with the following screen display:

ISO-18000-6C tag inventory
Connect the Reader correctly. Tag operation could be started when RF Setup is completed.
Tag inventory
means reader identifying multiple tags’ EPC number at the same time. This is the
core funtion of UHF RFID Reader and one of the standards to judge a reader’s performance.
3.3.1
Real Time Mode & Buffer Mode
The most commonly used mode for tag inventory is
Real-time
mode. Data will be uploaded
meanwhile you can find the tags’ EPC number instantly.
RSSI
and
Parameter of Frequency
are
changed and recorded in real time. Due to its dual CPU architecture, performance of multi-tag
identification under
Real-time
mode is the best.
The other is
Buffer
mode, the data will be cached and uploaded together when you need them.
When there are tags with small volume, the data is uploaded filtered and with no repeat. But it will
take some time to filter duplicate data when reader identifies a large number of tags. Therefore, its
identification efficiency will be slightly lower than real-time mode. Note: Tags can’t be operated when
you extract data in the cache.
Users can choose the appropriate method based on actual situation as illustrated below:
