2.4. Modify Reader Setting
There are several options that you can configure in the ReaderTool which you can
choose prior to starting the RFID Scanning/Inventory. You will be able to set the
parameter for the following options:
(1) Output Power - refers to the strength of the RF output the UHF RFID will
produce. It is measured in dBm. Range can be set from 5dBm to 31.5dBm
(increments of 0.5dBm).
(2) Antenna - refers to how many antennas are plugged in the RU224.
(3) Session - refers to a function in the EPC Gen2 standard for inventory of UHF
RFID tags. There are four sessions available in the settings. The following are
the recommended settings in various scenarios:
(4) Target - There are two status for the target, A and B. Target determines whether
a UHF RFID Tag will be read in which state, A or B. It is advised that Target be
set at A unless necessary.

Average Tag Response. Suitable for Tag Population >100
Session 2
Normally used when two readers need to do separate
inventories and a much longer persistence time can be
tolerated. Less often tag response rate.
