Tab. 4.2: Conducted power
EPCC1G2 Q:
Q parameter (integer 0÷15) is useful for the optimization of the inventory
efficiency: as a rule of thumb, if you have to read a huge population of tags you need to select a
high value for the Q parameter, otherwise you can select a lower value. For more information on
Q parameter see EPC Class1 Gen2 protocol specification [RD1]. Default value is EPCC1G2 Q =6.
You can change the default value using the drop-down menu.
EPC C1G2 Session:
Session used by the anticollision algorithm. The reader chooses one of four
sessions available (S0, S1, S2 and S3) and inventories tags within that session. For more
information on
session
see EPC Class1 Gen2 protocol specification [RD1]. Default value is
EPC
C1G2 Session
= S0. You can change the default value using the drop-down menu.
GPIO0 Trigger:
Through this option you can enable/disabled the tag inventory at the change of
state of the GPIO0. By default, the GPIO0 Trigger is disabled. You can change the default value
using the drop-down menu:
Enable (one shot):
enables the tag inventory each time the GPIO0 toggles from
Low
to
High
Enable (start/stop):
starts the tag inventory when the GPIO0 toggles to
High
and repeats
the inventory until the GPIO0 returns to
Low
(stop)
GPIO1 Trigger:
Through this option you can enable/disabled the tag inventory at the change of
state of the GPIO1. By default, the GPIO1 Trigger is disabled. You can change the default value
using the drop-down menu:
Enable (one shot):
enables the tag inventory each time the GPIO1 toggles from Low to High
Enable (start/stop):
starts the tag inventory when the GPIO1 toggles to High and repeats
the inventory until the GPIO0 returns to Low (stop)
Software Trigger:
Through this option it is possible to enable/disable the tag inventory via
software. By default, the software trigger is disabled. You can change the default value using the
drop-down menu. If enabled, the reader waits to receive xml data from the host to perform the
inventory. The xml data must be as follows:
<
trigger
><action>
value
</action><repetition><duration>

</duration><interval>

The reader with the FCC regulation cannot supply more than 1000 mW to the connector. By analogy with the power expressed in
the ETSI table, the percentage refers to the full scale of 1400mW, but the percentage of 80% and 100% (that exceed 1000mW) are
limited to the maximum of 1000 mW.
