SECTION TWO - Installation

3.Feed the open end of the supplied coax cable down through the antenna base and through the hollow core of the antenna mount.

4.Affix the TNC connector-end of the coax to the mating connector inside the upper half of the GPS antenna. Be sure to tighten it securely, as vibration can loosen the connection over time. In addi- tion, protect the coax-to-antenna connection with liquid electrical tape or self-vulcanizing electrical tape.

5.Align the upper half of the antenna with the bottom half and tighten the four screws. Be careful not to over-tighten the screws, as this may deform the watertight seal between the two antenna halves.

6.Make a termination for a male BNC connection—as described in the following steps—then connect the antenna to the female BNC con- nection at the back of the unit.

1.Strip cable jacket to the following dimensions (in inches), as illustrated in Figure 7: ‘Stripping the coax cable jacket,’ below: a=0.57, b=0.34, c=0.14, d=0.43. Do not nick the center conductor.

2.See Figure 8: ‘Flared cable braid,’ below: Slide outer ferrule on as shown. Slightly flare the end of cable braid, as shown, to facilitate insertion into inner fer- rule.

3.Place center contact onto center conductor so that it butts against the cable dielectric. Crimp the contact in place using Amphenol tool handle #227-944 and Cav- ity B of Die Set 227-980-3.

4.Install cable assembly into body assembly so inner fer- rule slides over dielectric and under braid. Push cable

961X, 961XD specifications

NorthStar Navigation has long been a leader in marine navigation systems, and the NorthStar 961XD and 961X are no exceptions. These cutting-edge devices bring advanced navigation capabilities to both recreational boaters and professional mariners, ensuring precise positioning and enhanced safety on the water.

The NorthStar 961XD is equipped with a powerful GPS receiver that delivers exceptional accuracy, even in challenging environments. This is achieved through a combination of differential GPS (DGPS) technology and support for WAAS (Wide Area Augmentation System). These features enable users to achieve positioning accuracy within a few meters, which is crucial for safe navigation in crowded or complex marine environments.

One of the standout features of the NorthStar 961XD and 961X is their intuitive user interface. The devices boast a large, high-resolution color display that provides clear visibility in various lighting conditions, including bright sunlight. The menu-driven system allows users to quickly access essential functions, making it easy to plot courses, set waypoints, and track routes on the go.

Both models support advanced charting capabilities, including the ability to display vector and raster charts. The chart database can be easily updated via USB, ensuring that users have access to the latest navigational information. This is particularly important for long-distance cruisers navigating through unfamiliar waters.

Another significant feature of the NorthStar 961XD and 961X is their integrated fishfinder capabilities. With sonar technology, users can locate fish, understand the underwater topography, and enhance their fishing experience. This dual functionality makes the devices versatile companions for both navigation and hunting for the next big catch.

Connectivity is another important aspect of the NorthStar systems. Both models feature multiple connectivity options, including NMEA 0183, allowing seamless integration with other onboard electronics such as autopilots, radars, and AIS systems. This enhances the overall situational awareness and safety of the vessel.

Finally, the rugged design of the NorthStar 961XD and 961X ensures they can withstand the harshest marine environments. With water-resistant housing and durable construction, these devices are built to last, providing reliable performance year after year.

In summary, the NorthStar 961XD and 961X deliver a winning combination of advanced navigation technologies, user-friendly interfaces, integrated fishfinding capabilities, and robust construction. These features make them indispensable tools for anyone serious about safe and efficient navigation on the water.
