Alignment
Tips
• To accurately align the airFiber radios for best
performance, you MUST align only one end of the link at
a time.
• For more convenient alignment, you may consider using
long-range scopes (not included) temporarily attached
to your airFiber radios.
• 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.
Determining the Received Signal Level
There are three methods for determining the received
signal level:
• LED Displays (See the next column.)
• airFiber Configuration Interface (See
“Using the
airFiber Configuration Interface” on page 14
.)
• Audio tone (Optional equipment required. See
“Using
the Audio Tone” on page 16
.)
Using the LED Displays
Before a link is established, the
Master’s LED Display
looks
like this:
•
GPS
and
Master
LEDs are solidly lit
Note:
The
GPS
LED may not be lit if there is a
weak GPS signal. A GPS signal is not required for
alignment.
•
Link Status

Note:
The

may briefly flash a
large number (such as 95) when there is no link.
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. Ensure that the following bolts and nuts are loose:
• Four
Pre-Installed M10x25 Flanged Bolts
on the
airFiber radio (two on each side)
• Four
M10 Hex Nuts
used to lock the elevation
alignment on the
Upper Mount Bracket
(two on
each side)
