6.5.3. Link test
Basic parameters of the link are shown in the menu Status – Brief, its quality is characterized by RSS
and SNR. Values on Status screens can be refreshed manually by pressing the Refresh button or
in real time with a period of several seconds after activating the Start button. Press the Stop button to
terminate the periodic refresh of values.
The RSS, SNR and BER values can also be viewed on the screen Tools – Live data – Bar indicators.
After pressing the Start button, values will be refreshed with a period of one second.
After installation, it is good to reset the statistics using the Clear stats button in menu Status – Detailed.
This allows easier diagnostics of the link’s reliability over time.
6.5.4. Parameters setup
After both antennas have been aligned, setup operation parameters for the link. In the case of links
operating in the free band, setup the parameters based on survey results from the tool Tools – Live
data – Frequency analyser. In the case of links operating on a licensed band, setup the parameters
based on the assigned license:
• Bandwidth
• Channel Selection (TX / RX channel)
• Modulation (TX modulation) – ACM is recommended. When selecting fixed modulation it is necessary
to account for the fade margin. If fixed modulation is setup close to a possible maximum, then a
deterioration in RSS could endanger the link both for data transfer as well as service access.
• Transmit power (TX power), or ATPC
• Verify and record IP addresses
• Define access channels – https / telnet / ssh / ssh with password
• Check the users password settings.
Restart both units by interrupting their power supply and verify the status of the link. This verifies that
all parameters have been stored correctly in the memory.
Select Tools – Maintenance – Backup – Settings (Local & Peer) - Download and save the configuration
to backup file “cnf_backup.tgz”.
This completes the installation. Further configuration can be performed remotely.
