1)
The internal time stamp of the reader that relates to this event is output. The internal reader time stamp is not synchro-
nized with UTC.
2)
The value "Reads" indicates the total transponder recognitions (inventories) regardless of the set smoothing parame-
ters. In this way, in extreme situations, the "Reads" counter can reach extremely high values without the transponder
ever reaching the "Observed" status.
3)
The "current_Power" value is specified as transmit power in 0.25 dBm steps (ERP/EIRP). A "current_Power" value of
"72" (0x48) therefore corresponds to 18 dBm (ERP/EIRP).
