CAUTION: Over-tightening the smart antenna on the pole or using a tool could
damage the threaded socket in the base of the antenna. In addition, do not use
thread-locking compounds, since they can corrode plastic
2.4.2. Connecting the GPS Smart Antenna to the Display
A standard 50 foot long interface cable (Evertz part WA-T09) is provided with the GPS version of the
display and the smart antenna. One end of this cable is fitted with a weather-tight 12 pin Molex
connector. The other end is fitted with a 9 pin male sub-miniature D connector and should be connected
to the GPS connector on the rear panel of the display. The pin out of the cable is shown in Figure 2-9. If
you require a longer cable, a 100 foot (Evertz part WA-T76) or 400 foot cable (Evertz part WA-T11) may
be ordered from the factory. Custom length weatherproof cables can also be special ordered.
Alternately, you can wire a 9 pin Extender cable as shown in Figure 2-10.
Connect the 12 pin connector on the interface cable to the smart antenna. The connector on the interface
connector has a locking ring for securing the connection.
CAUTION: Over tightening the locking ring can damage the connector on the smart
antenna.
Route the interface cable to the location of the display using the most direct path. Avoid routing the cable
near hot surfaces, sharp or abrasive surfaces, or corrosive fluids or gases. Avoid sharp kinks or bends in
the cable. Additional protection such as heat shrink tubing may be required to protect the cable jacket at
points where the cable enters the building, especially if the opening is rough or sharp. Once the cable is
run, use cable-ties to secure the cable to the pole and to provide strain relief for the connections. When
securing the cable, start at the antenna and work towards the display. Connect the 9 pin male D
connector to the GPS connector on the rear panel of the display. Power is provided from the display
along the interface cable to the smart antenna.
