RSSI Events
RSSI events provide information about the signal strength of the transponder responses.
The number of these events is significantly higher than that of the tag events and they are
sent per identification (inventory) and in some cases even per antenna. This results in a
precise series of events during the identification process, however it leads to a lot of data
traffic particularly if large numbers of transponders are passing through the antenna field. For
this reason, we recommend that you only activate RSSI events when diagnostics is
necessary.
For the reader to report the RSSI events events that occur to the XML API interface, the
"Enable" check box must be selected.
The following additional data of the RSSI events can be configured:
Table 7- 18 Description of the event data "RSSI events"

IO Events
For the reader to report the IO events that occur to the XML API interface, the "Enable"
check box must be selected.
All events (edge change) of the digital inputs/outputs are always reported to the XML API
interface.
You will find more information on events in the section "Events (Page 266)".
