body into which the upper half is secured (see Figure 15, “ACU Assem- bly”). A gasket and rubber O-ring on the upper half provide weathertight sealing when the two halves are secured. The bottom of the base is threaded (1"–14) to mount onto an antenna mast or onto a standard deck mount.

Figure 15: ACU assembly

CAUTION!

Maintaining the ACU’s weathertight seal between its upper and lower halves requires only hand-tightening the two together. Using a wrench or other tool may distort the gasket or housing/ rubber O-ring inside, or break the coupler base.

The ACU connects to the 961X with RG-58U coaxial cable, which carries signals to the differential receiver and DC power to the ACU amplifier. See Figure 16 below for the correct AN150/8410 wiring. A 25-foot length of this cable is supplied with the unit; this cable may be extended up to a length of 300 feet. The cable passes up through the hollow ACU base and connects to the PL-259 (UHF) connector at the bottom of the ACU. For UHF connector preparation, see“Differential GPS antenna cable connec- tors” beginning on page 25.

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.
