2. Ensure that the pole mount is snug yet the four
M10
Hex Nuts
attaching the
Pole Clamps
are loose enough to
allow rotation around the pole for azimuth alignment.
3.
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
.
4.
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
Link
Status
LED is solidly lit green and the
Remote
and
Local
LED Displays
of the
Slave
are displaying signal levels.

6.
Slave
Aim the
Slave
at the
Master
to achieve the
strongest signal level on the
Remote LED Display
of the
Slave
.
Note:
Values on the
LED Displays
are displayed in
negative (-) dBm. For example, 67 represents a
received signal level of -67 dBm. Smaller numerical
values indicate stronger received signal levels. For
example, a reading of 49 is stronger than a reading
of 55.
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
Remote LED Display
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
Local
and
Remote LED Displays
of each
airFiber radio to ensure that the values remains
constant while tightening the nuts and bolts. If any LED
value changes 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.
