5.3 Mounting bracket fixing:
Fix the mounting bracket with the provided screws. This must be very tight to hold the
bracket, if the provided screw is fixed successfully, in that case the console should hold at
around 100 kgs. Optionally extended bracket can be ordered with the pico systems which
are longer and stronger than the standard one. For further information please ask your
local distributor!
5.4 On-the-table test
All Pico units were preset and pretested before shipping!
Warning! Do not look either into the transmitter or the receiver optics because at this
distance even the reflected laser beam can be dangerous to your eyes. Operating the
system on much shorter distance than presumed originally can cause saturation or even
permanent damage to the receiver. Always use optical attenuators for this kind of test.
The on-the-table test is easy to do. The units should be placed at about 2 m distance from
each other with optical windows facing one another. Put an appropriate optical attenuator
between the heads. Make all the necessary connection as described earlier to connect your
device to the heads and power up the units. Turn ON the Outdoor Interconnection Units
and check if the power LED is ON on the head.
You should be able to align the units without any tool and get full received level on the
signal strength LED’s. Make sure that the “Saturation” indicator is OFF. Adjust your
attenuators if necessary to avoid saturation of the receivers. After obtaining the desired
received level, check the data connection between devices. If there is a transmission
problem check the status of the connecting devices (e.g. link ON) and cables. If there’s no
LINK signal, connect the network equipments back-to-back omitting the Black Box
system to ensure that they work properly. Should they operate well, get in contact with
your supplier or call the technical support (a Problem Report Form can be found at the end
of this book).
