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‑4X is fully
booted.
Signal Level
Once fully booted, the Signal 1-4 LEDs act as a
bar graph showing how close the AF‑4X 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‑4X. 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.
