Airmux-200 Ver. 1.750 Evaluating the Link D-3
When the SA reads the expected receive signal, the antennas are aligned and
there is an indication of a good link between the sites.
6. Tighten the antenna azimuth axis and elevation axis.
7. Stop the CW function.
The NMS will restart the system.
8. Connect Airmux-200-AIND unit to external antenna. See
Airmux-200
Installation and Operation Manual
for details. The operational link is shown in
Figure 2-3 .
9. Configure Airmux-200 NMS at both sites to operate at the pure channel
frequency found in the RF survey.
Airmux-200 is now ready for operation.
D.3 Configuring the Link
1. Run the Installation Wizard in the Airmux-200 Manager Software to set the
configuration of the link.
2. Configure the link in accordance with the parameters calculated in the Link
Budget Calculator.
3. Airmux-200 has a unique identification number, the SSID. Each side of the link
looks for its partner with the same SSID. Therefore both sides of the link
must be configured with the same SSID.
4. The Airmux-200 link is now ready for operation.
D.4 Evaluating the Link
With the link operating at a pure channel as determined by the RF survey
procedure, the recommended performance threshold of an Airmux-200 link is the
following:
RSS: –84 dBm minimum
There are cases when there is no line of sight, but still the link is of an acceptable
quality.
If the link is not within the acceptable limit, see
Alignment Troubleshooting .
