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.
Slave
Listen to the audio tone of the Slave – the higher
the pitch, the stronger the signal strength. Aim the
Slave at the Master to achieve the strongest signal level
on the Slave.
Note:
Maximum signal strength can best be
achieved by iteratively sweeping through both
azimuth and elevation.
6.
Master
Aim the Master at the Slave to achieve the
strongest signal level on the Master.
Note:
If the Overload LED lights up, identify
and eliminate any source of strong in-band
interference.
7. 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.
Note:
If you have difficulty discerning whether the
link is symmetric, you can use one of the following
methods to determine more precise, received
signal level readings.
• LED Display (See “Using the LED Displays” on
page 12.)
• airFiber Configuration Interface (See “Using
the airFiber Configuration Interface” on page
14.)
8. Lock the alignment on both airFiber radios by
tightening the nuts and bolts.
9. Listen to the audio tone for each airFiber radio
to ensure that the values remains constant while
tightening the nuts and bolts. If the audio tones
change during the locking process, loosen the nuts
and bolts, finalize the alignment of each airFiber radio
again, and retighten the nuts and bolts.
10. For each airFiber radio, close the port cover and ensure
that the Ethernet cable stays in the cable feed slot.
