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.
