can click only the Back button of your browser to do so.
26.6.1 Alignment Page (SM, BHS)
An example of the Alignment screen is displayed in Figure 112 on Page 280.
Modes
The Alignment web page provides tools to assist in the alignment of an SM to an AP (or
BHS to a BHM). Whether and how these tools operate depends on the mode that you
invoke. The following modes are available:
◦ Normal Aiming Mode
◦ RSSI Only Aiming Mode
◦ Operating Mode
Regardless of the mode that you select to align the module, you must achieve all of the
following indications for an acceptable link between the modules:
◦ RSSI greater than 700
◦ jitter value between 0 and 4 in Release 4.0 and later releases or between 5 and 9
in any earlier release
◦ uplink efficiency greater than 90%
◦ downlink efficiency greater than 90%
IMPORTANT!
If any of these values is not achieved, a link can be established but
manifest occasional problems. In Release 4.0 and late releases, RSSI
measurement is more consistent and jitter control is improved.
In either aiming mode, you must either set the Alignment page to automatically refresh or
repeatedly click the Enable Aiming Mode button to keep current data displayed as the
module is moved. After 15 minutes in an aiming mode, the module is automatically reset
into the Operating Mode.
Normal Aiming Mode
In the Normal Aiming Mode
◦ the screen displays the RSSI level and the jitter value.
◦ the five left-most LEDs in the module act as a bar graph that indicates the best
achieved RSSI level and jitter value when the greatest number of LEDs is lit.
(The colors of the LEDs are not an indication in this mode.)
To invoke the Normal Aiming Mode
1. ensure that the Disabled button on the RSSI Only Mode line is checked.
2. click the Enable Aiming Mode button. (The aiming procedure is described on
Page 280.)
