Basic settings
In this area, you can select the antenna whose alignment needs to be optimized. With the
"Start/Stop adjustment" buttons( / ), you can control the measurement of the RSSI values.
By clicking the
on the selected antenna and the measured values obtained are displayed. Any existing
measured values from a previous measurement are deleted. By clicking the
measurement is stopped.
Transponder list
After you have started measuring the RSSI values, all the transponders identified by the
reader are listed in the table. Select the "EPC-ID in ASCII format" check box to display the
EPC-IDs of the transponders in ASCII code.

You can select the transponders individually in the table. The selected transponder is
highlighted in color and its measured values shown in the "RSSI display" area.
RSSI display
This area shows the measured RSSI values of the selected transponder. The bar chart
shows the maximum measured and the current or last measured RSSI value of the
transponder. The current RSSI value of the selected transponder is also displayed as a
numeric value. Using the arrow symbols, you can expand or reduce the window for the
numeric RSSI value. This allows you to read the current RSSI value even from greater
distances so that you can find the optimum alignment for the highest RSSI value quickly and
simply by varying the antenna position.
The RSSI value is also displayed by the status LEDs of the RF680R/RF685R readers and by
the "PRE" LED of the RF650R reader. Low RSSI values are shown in red, medium RSSI
values in yellow and high RSSI values in green.
