impulses are terminated on the IDU case by the winding shield, and further – on
the grounding contour. The data & power wires pickups on the top are
terminated via ODU protection scheme; on the bottom – via IDU protection
scheme (discharger and additional air gap). ODU and IDU grounding contours
are connected with 100 kOhm resistor, and that provides no static charge
accumulation on the ODU case if there are some problems with its connection to
the grounding contour.
Antenna pole, tower, ODU and lightning arrestor should be connected
to the first common grounding contour. Cable thickness should be no
less than 10AWG using corrosion-steady connectors. It is highly
recommended to entrust grounding contour development to the
skilled personnel. IDU should be grounded to the same contour as
customer LAN, having the second common grounding contour.

Antenna alignment
To obtain maximal system performance antennas must be precisely aligned one
towards another according to LOS requirements. General recommendations for
antenna alignment are the following:
• Align antennas using optical equipment (binoculars, spyglass)
accompanied by mobile phone actions coordination
• Use GPS receiver and area map
• Use build-in InfiNet Wireless Router features. These features allow
evaluating current channel/signal quality and perform precise antenna
alignment
Omni-directional and sector antennas have a wide radiation diagram width, thus
usually they either do not require a very precise alignment or it is just not
necessary due to radio link requirements.
Antenna polarization must be taken into consideration while installation. In most
cases omni-directional and sector antennas have a vertical polarization.
Directional antennas can be installed either with vertical or horizontal
polarization. Please check a corresponding labeling on the antenna and address
to the antenna technical documentation.
Sound indication usage
Sound indication is performed in channel testing mode (RMA command with
Autotest option). The device is intended to be used while preliminary link
establishing and antenna alignment procedure in order to obtain the maximum
signal level from the remote side.
When having AudioMonitor plugged into the console port of the device with
headphones plugged in, the sound signals will be sent to the headphones. The
AudioMonitor or the console cable must be plugged in when the device is
powered off.
No return packets state on the testing device input (no link) with described
testing mode turned on is indicated by seldom tones in the headphones.
If there is a link established, the signal level is indicated by the set of clicks. The
higher the signal level, the higher is the frequency of the clicks and their number
in the set. The durability of the set and the interval between the sets is always
the same and has a value of 2 and 0.5 seconds correspondingly. The indication
cycle always corresponds with a PREVIOUS measurement cycle. That means that
the sound indication has a delay of 2.5 seconds.
The maximum signal level (16) is indicated by a permanent tone.
