Figure 32 Basic reading: mode
ᬅ
Synchronous
allows the facility to switch the carrier off during the idle times, saving power.
This mode is intended for applications in which the requirements for timing are not
very demanding. The inventory of the tags is performed across all the antennas that
are configured. Once all the tags in the field have been read on the last antenna,
data are sent to the PC. The PC automatically retriggers the inventory of the tags.
ᬆ
Asynchronous
is intended for applications for which maximum performance is required
The reader starts the inventory as quickly as possible, and at the end of an inventory
it does not deliver every tag that was read to the PC, but only those that have
recently appeared in the field or left it. This way, the time required for
communication between the reader and the client is minimized.
The timing of when a tag was reliably read in the field and when the tag no longer
appears in the field can be defined more precisely using parameters.
Ź For more details of the ObservedThresholdCnt and ObservedTimeoutCnt
parameters, refer to the Configurational manual reader.
