Antenna multiplex configuration
The sequence in which the antennas are used to read the tag can be set under this header. If this antenna is
not activated, the system proceeds to the next entry on the multiplex list. For asynchronous operation of the
reader, the exposure time on the antenna can also be specified. See section [2] „Configurational manual“,
sections MultiplexingAntennaport and MultiplexingExposureTime for more details.
RF settings
Depending on the regulative region, the reader transmits in the frequency range 865 MHz to 868 MHz for
Europe or 902 MHz to 928 MHz for USA / FCC.
In Europe the number of channels to be used can be limited. For this purpose the related check box for each
channel the reader is to use must be selected on the Available channels pick list. In this manner it is
possible to avoid from the start the usage of specific channels on which there is or might be interference.
Each read command connects the channels under country-specific conditions and in accordance with the
selected communications standard. The reader then starts to search through the channels in ascending
order.
In the Communication standard drop-down menu, the reader can be switched to a different country-
specific communications standard. The device firmware defines which customized standards are available.
The modulation type can be switched between double sideband and PR-ASK modulation in this drop-down
menu.
The communications profile is critical for the data rate and the read reliability. This option allows the
technician to directly influence the performance of the reader and the spectrum of the signal. The profile
denominations contain basic indications on the transmission and reception data rates.
Note: The optimal data rate may be subject of the used tag.
The Time until carrier stand-by parameter specifies how long the carrier of the reader remains active on the
air interface after the last action. Once this time has elapsed the carrier is switched off.
Selection parameters
In this section the user can configure the simulation the tags to the EPC standard (see EPC global standard).
The parameters can be selected in the drop-down menu and have the following meanings:
No. Parameter Function
1 Initial Q value Reflects the number of tags expected in the field. (see [2] and look for InitialQ)
2 Sel Specifies whether other parameters are of interest for an inventory of the tag
population, or not. (see [2] and look for QuerySel)
3 Sessions This configuration parameter instructs the reader the session with which it should
work. (see [2] and look for Sessions)
4 Target Specifies which tags in the population should participate in the inventory. (see [2] and
look for QueryTarget)
