SECTION THREE - Interfacing

NOTE:

If you’re viewing and editing information on the PORT OUTPUT SETUP screen, and you press one of the five function keys to view other data, the 961 immediately cancels your edit-in-progress so that you can view the data requested by your function keypress. To resume editing at the PORT OUTPUT screen, you must return to that screen and re-enter the data that you lost when you pressed the function key. To purposely cancel an edit-in-progress, however, you’d normally press the CANCEL key.

Setting the output format

The unit will output navigation data in any of several standard formats as required by the receiving, or “listener,” device. Upon pressing the EDIT menu key at this option, you’ll find the following choices available: NMEA 0180, NMEA 0183, (DATAMARINE) CDX, 0183-R,and OFF.

•NMEA 0180 is an infrequently-used format, developed in the late 1970’s and required by certain older autopilots.

•NMEA 0183 V2.1 is a general-use interface output format is used by most autopilots, radars, plotters and other equipment. The NMEA 0183 Version 1.5 sentences (BWC, GLL, and RNN) enable the 961 to be backward-compatible with marine equipment previously designed for this earlier version of 0183. For details on using the 0183 format, see ”About NMEA 0183 and RAY 0183” starting on page 48.

•0183 RAY is used when transmitting/receiving position information to/from Raytheon equipment. It uses Raytheon’s non-standard NMEA 0183 checksum, where, on output, the checksum is not included, and on input to the 961, the checksum is ignored. (It should be noted that, with the checksum ignored on input, there is a possibility of the unit receiving contaminated NMEA data when it is connected to an external Raytheon loran.) Format is supported on PORT 1, PORT 2, and PORT 3.

•DATAMARINE CDX is required by Datamarine’s cross-track error indicators, the latest of which display distance and bearing to the waypoint.

•The Off setting helps to isolate noise problems potentially caused by I/O.

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.
