Master
Visually aim the
Master
at the
Slave
. To adjust
the
Master
’s position:
a. Rotate the airFiber radio on the pole to align the
azimuth.
b. Use the hex nut on the
Elevation Rod
to adjust the
elevation.
Note:
Do NOT make simultaneous adjustments on
the
Master
and
Slave
.

Slave
Visually aim the
Slave
at the
Master
. To adjust the
Slave
’s position:
a. Rotate the airFiber radio on the pole to align the
azimuth.
b. Use the hex nut on the
Elevation Rod
to adjust the
elevation.
5. Check to see if a link is established. Ensure that the
local and
Remote
Signal Strength
bar graphs are
displaying signal levels.
6.
Slave
Aim the
Slave
at the
Master
to achieve the
strongest signal level on the
Remote Signal Strength
bar
graph
of the
Slave
.
Note:
The
Signal Strength
bar graphs display the
absolute power level (in dBm) of the received
signal for each chain. Smaller numerical values
indicate stronger received signal levels. For
example, a reading of -49 dBm is stronger than a
reading of -55 dBm.
Note:
Maximum signal strength can best be
achieved by iteratively sweeping through both
azimuth and elevation.
7.
Master
Aim the
Master
at the Slave to achieve the
strongest signal level on the local
Signal Strength
bar
graph of the
Master
.
Note:
If the Overload LED lights up, identify
and eliminate any source of strong in-band
interference.
8. Repeat steps 6 and 7 until you achieve a symmetric
link, with the signal levels within 1 dB of each other.
This ensures the best possible data rate between the
airFiber radios.
9. Lock the alignment on both airFiber radios by
tightening the nuts and bolts.
10. Observe the
Antenna Alignment
window to ensure
that the values remains constant while tightening
the nuts and bolts. If the values change during the
locking process, loosen the nuts and bolts, finalize the
alignment of each airFiber radio again, and retighten
the nuts and bolts.
11. For each airFiber radio, close the port cover and ensure
that the Ethernet cable stays in the cable feed slot.
