Bootup to airOS

When powering on, the Power, GPS, LINK, and Signal 1-4 LEDs light on. Once the CPU code takes over, the

GPS, LINK, and Signal 1-3 LEDs turn off. Signal 4 LED remains on to indicate the boot sequence is underway.

Initializing airFiber Software

When the airFiber application begins to boot under airOS, the Signal 4 LED goes from solidly on to a 2.5 Hz flash. This continues until the AF-2X is fully booted.

Signal Level

Once fully booted, the Signal 1-4 LEDs act as a bar graph showing how close the AF-2X is to ideal aiming. This is auto-scaled based on the link range, the antenna gains, and the configured TX power of the remote AF-2X. Each Signal LED has three possible states: On, Flashing, and Off. All Signal LEDs would be solidly on in an ideal link. If the link has a 1 dB loss, the Signal 4 LED will flash; a 2 dB loss and the Signal 4 LED will turn off. The full bar graph LED states are shown below.

Alignment

Tips

• To accurately align the airFiber radios for best performance, you MUST align only one end of the link at a time.

• You may need to use additional hardware to compensate for issues such as the improper orientation of a mounting pole or significant elevation differences between airFiber radios.

Establishing a Link

Adjust the positions of the Master and the Slave to establish a link.

Note: The Master must be aimed first at the Slave because the Slave does not transmit any RF signal until it detects transmissions from the Master.

1. Master Visually aim the Master at the Slave. To adjust the

Master’s position: a. Loosen the four pole clamp nuts, and rotate the airFiber antenna on the pole to align the azimuth.

b. Loosen the six elevation bolts, and use the hex nut on the elevation rod to adjust the elevation.

Note: Do NOT make simultaneous adjustments on the Master and Slave.

2. Slave Visually aim the Slave at the Master. To adjust the

Slave’s position: a. Loosen the four pole clamp nuts, and rotate the airFiber antenna on the pole to align the azimuth.

b. Loosen the six elevation bolts, and use the hex nut on the elevation rod to adjust the elevation.

3. Check to see if a link is established. Ensure that the LINK

LED is solidly lit green and the Signal LEDs of the Slave are displaying signal levels.

4. Slave Aim the Slave at the Master to achieve the strongest signal level on the Master.

Note: Refer to the Signal LEDs section for details on the signal values.

Note: Maximum signal strength can best be achieved by iteratively sweeping through both azimuth and elevation.

5. Master Aim the Master at the Slave to achieve the strongest signal level on the Slave.

6. Repeat steps 4 and 5 until you achieve an optimal link, with all four Signal LEDs solidly lit. This ensures the best possible data rate between the airFiber radios.

7. Lock the alignment on both airFiber antennas by tightening all the nuts and bolts.

8. Observe the Signal LEDs of each airFiber radio to ensure that the values remain 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 antenna again, and retighten the nuts and bolts.
