Tsunami Multipoint Version 1.3 Installation Guide
The Base Station Unit (BSU) is shipped with a dust cover over the large 18-pin connector. Keep
this cover on until ready to mate with cable connector to avoid getting the connector wet.
To ensure proper weatherproofing, follow these procedures to connect the supplied Cat 5 cable
to the BSU’s Power and Ethernet port.
A. Check the BSU connector. The only moving part should be the plastic nut (“B”), which screws
onto the BSU housing.
B. If there is any movement or play between parts A and C, you must tighten these parts before
proceeding; otherwise you could cause connector pins to disconnect or break when you apply
the weatherproofing tape. To tighten, first loosen (but do not remove) the connector’s
screws (indicated with arrows in the previous figure).
C. Then, while holding the pin connection portion (1), turn the bottom portion (2) clockwise until
there is no more movement, making sure you do not over-tighten.
D. Re-tighten the screws.
E. When mating the BSU to the cable connector, first apply a bead of silicone grease or RTV to
the 3mm-wide outward-most flange on the BSU connector (or in the outer ring of the cable-
end mating connector).
F. Then tighten the plastic nut on the cable end to 16 inch-lbs (1.81 N-m). The cable connector
must be tightened onto the BSU sufficiently to compress a small O-ring that resides inside the
male BSU connector. If the O-ring is missing or insufficiently compressed, moisture can get
through into the connector pins.
