4.3 Cable installation
The length of the cable from the terminal to the next network component may be up to 100 m (328 ft), but
should be kept as short as practical in order to reduce signal loss. All Ethernet cables must be CAT 5e
compliant and suitable for outdoor use. The cable must be UV stable, UL approved and must comply with
local and/or national building codes.
4.4 Antenna alignment
One of A060-Mini
®
link’s biggest advantage is its fast, easy alignment procedure.
The terminals can be coarse aligned optically by using the alignment tool. Electrical alignment is then
used for fine grain accuracy.
The table below shows alignment tolerance:
4.4.1 Alignment Procedure
The following procedure achieves fast, accurate alignment (for all operations, the
enclosed 5 mm allen key can be used):
4.4.1.1 Optical alignment
1. Place the alignment tool to the most accessible corner and ensure good visibility to
the opposite terminal by rotating the telescope.
2. Loosen the horizontal lock screws (labeled “3”)
3. Place the horizontal axis course screw in its middle position
(needle).
4. Carry out a rough alignment on the horizontal axis and fasten the
screw (labeled “1”).
5. Repeat steps b), c) and d) for the vertical axis.
6. Turn the horizontal course screw (labeled “2”) by viewing through
the telescope and carrying out the fine alignment.
7. Repeat e) for the vertical axis.
8. If necessary, repeat the fine alignment procedure e) for both axes
until the opposite link is correctly aligned.
9. Fasten the lock screw (labeled “3”) on both horizontal and vertical axes.
