SECTION TWO - Installation

The 8410 ACU has a separate black ground wire inside the coupler base, this wire should be connected to an electrically quiet ground location. This wire is the AC signal ground connection from the antenna input cir- cuit. The purpose of bringing it out is to make available a separate signal ground path. Use #16 AWG minimum for grounding. If possible, use a grounding “strap” that is designed for this purpose.

Other electrical equipment onboard can cause large amounts of electrical noise, even at points that appear well-grounded. Try several ground points (ground plate, vessel ground, engine block, and so on) to deter- mine which works best under different conditions.

WARNING!

Whenever any antenna is disconnected from on-board equip- ment, be sure to ground the antenna shield in order to dis- charge extremely large static voltages that can quickly build up on an ungrounded antenna system. These voltages are haz- ardous to personnel and equipment!

Differential GPS antenna cable connectors

Both ends of the differential beacon receiver antenna cable end in UHF connectors. To prepare UHF connectors, follow the assembly instructions in Figure 17. For best results, coat these connectors with silicone dielec- tric grease (DC 4 or equivalent) to protect the connector junction against water intrusion and surface corrosion of the contacts.

In addition, the connector area including the shield-to-connector junc- tion and jacket-to-crimp ferrule area can be protected with liquid electri- cal tape (Starbright Liquid Tape comes in color-coordinating black or white), or self-vulcanizing electrical tape (Tommy Tape).

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.
