3. Login to the end of the link that is being aligned.
4. Run linktest 99 command while adjusting the antenna(s), and monitor
the BNC output voltage until the expected voltage/RSSI level is reached.
The voltage at the BNC will range from 0.1 Volts at -90 dBm input level to
4.5 Volts at -20 dBm input level. Use a voltmeter and CBLDAT-RSSI to
monitor the voltage while adjusting the antenna. The following equation
can be used to determine the RSL within 3 dB accuracy
RSL (dBm) = 15.77 x VBNC -91.58
Below is a table showing the voltage to RSL for convenience.

5. Once satisfied with the RSSI reading, tighten down the antenna in the
optimum position.
6. Replace the sealing cap on the BNC connector and tighten until it clicks into
place.
