Sensitivity of Antenna Connection Detector is set by users which is the Return Loss of antenna port, the

unit of which is dB. The larger this value is, the better impedance matching requirements between

antenna and port. For normal antennas, you can set the threshold to 3-6dB. Sensitivity of Ceramic

Antenna and Handset could be more lower.

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:

2.3 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

function of UHF RFID Reader and one of the standards to judge a reader’s performance.

2.3.1 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:

Method NO.1: Real-time Mode

1. Click Tag Inventory (Real Time Mode). Select the connected antenna(s) port. Set the number of
