RSSI Only Aiming Mode
In the RSSI Only Aiming Mode, the screen displays the signal strength based on the
amount of energy in the selected frequency, regardless of whether the module has
registered. This mode simplifies the aiming process for long links, such as where the
module is mounted to a Canopy Passive Reflector.
To invoke the RSSI Only Aiming Mode
1. select the frequency of the AP in the Configuration Page of the SM. See Custom
RF Frequency Scan Selection List on Page 208.
2. click the Enable button on the RSSI Only Mode line of the Alignment page.
3. click the Enable Aiming Mode button. (The aiming procedure is described on
Page 280.)

BER Display
This page displays the current bit error rate in the link, but only if the AP or BHM is
configured to send the BER stream.
The value in the Measured Bit Error Rate field represents the BER at the moment of the
last browser refresh. To keep the value of this field current, either repeatedly click the
Refresh Display button or set the screen to automatically refresh.
BER Results
The link is acceptable if the value of this field is less than 10
-4
. If the BER is greater than
10
-4
, re-evaluate the installation of both modules in the link.
