5. Connect the coax cable assembly (comcode 847565132) to the outdoor
CAU. Dress the cable down the side of the building to the grounding block.
Attach the cable to the building as required. Be sure to avoid crushing or
otherwise distorting the cable. Make the connector finger-tight only. Using
tools damages the WFB.
6. Cut the coax cable at the grounding block, and ensure that you leave
enough material to form a drip loop. This is the only cable cut permitted. Do
not cut the coaxial cable once it is connected to an active WFB. This
could short and subsequently damage WFB ports. (See the following
“Note.”)
7. Connect the remaining cable to the WFB, and route the cut end through the
previously prepared cable passage.
NOTE:
The DWBS is designed to use the supplied 100 foot coax cable to
interconnect the WFB and the CAU. Using either shorter or longer
cables degrades system performance and violates FCC regulations.
Once the cable is cut in Step 6, do not shorten either portion of the
cable by cutting the cable again. Also, do not mix and match cable
pieces from other outdoor CAUs. If 100 feet of coax cable is
insufficient to interconnect the outdoor CAU and WFB, the WFB
should be moved closer. If this is not possible, the outdoor CAU must
be relocated with guidance from the WiSE Engineering team.
8. Strip the ends of the coax cable, and install the coax connectors as shown
and explained in the following figure. Use only the TNC connectors
provided with the outdoor CAU. These connectors are specifically
designed for use with the supplied cable. Appropriate coax stripping and
connector crimp tools are identified in the following tables.
