Choosing the NMEA 0183 talker ID

Figure 26: Port 1 output setup screen

To set the output sentences to the factory default settings, press the DEFAULTS ON key. To turn on only a select few sentences, press the CLEAR ALL key, then turn the desired sentences back on.

To modify the unit’s NMEA 0183 sentence output format, first follow the above description to display the 0183 sentence screen, then perform the following steps:

1.At the PORT 1 OUTPUT SETUP (SENTENCES) screen, display the list of sentences, then press the EDIT key.

2.Press the CURSOR PAD to select the desired sentence.

3.Press the ON/OFF key.

4.Press the ACCEPT key.

5.Repeat for each sentence requiring modification. Press the RETURN menu key to go back to the PORT OUTPUT SETUP screen.

Part of the NMEA 0183 standard requires that the equipment you are interfaced to—the “listener”—know what type of device is transmitting the data. The talker ID tells the listener that it is receiving information from a navigation source (the 961) and not a communications or sensor device, which transmit completely different—and therefore unusable—forms of data.

The “talker ID” enables you to configure the 961’s output data to tell the listener it is receiving data from either a GPS (GP) navigator or Integrated Instrument (II). The choice you make depends on what the listener device is expecting.

1.Check the listener device’s instruction manual to determine which “talker ID” codes it will respond to.

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.
