Changing the output rate

Changing the NMEA 0183 waypoint ID

SECTION THREE - Interfacing

The 961 normally uses a two-second update interval for data transmis- sion. Some applications require a longer update period, so the 961 lets you increase that span to 199 seconds. You can choose a one-second interval, but at that rate, the bandwidth of 4800-baud NMEA data only allows the output of a reduced set of sentences.

To change the output rate:

1.From the PORT OUTPUT SETUP screen, press the CURSOR PAD to highlight the SEND EVERY field.

2.Enter a number, then press the ACCEPT key (or press CANCEL to leave the option unchanged).

Many marine electronic devices (such as radars and electronic plotters) can display your waypoint names, rather than a number, if they’re output by the 961.

If the peripheral equipment has this capability, at the PORT OUTPUT SETUP screen, change the 961’s 0183 WAYPTS field from NUMBERS to NAMES, by highlighting the field, making the change, and pressing the ACCEPT key. The listening device will now display the nine-character waypoint names. Included spaces will be output. When exporting to another device, be aware that the numerical identifiers aren’t assigned sequentially and may be re-used by the system on a random basis.

NOTE:

Be sure to verify this capability in the listening device before changing the 0183 WAYPTS field. Most older equipment

won’t understand this identifier, and using it may cause prob- lems with the display of the waypoint information.

Setting the NMEA 0183 checksums

Certain older devices may not accept sentences containing the NMEA 0183 checksum that’s output by the 961. In such cases, the device may not operate properly, if at all.

If you encounter difficulty when interfacing to older equipment, the 961 offers you the flexibility of turning off the NMEA 0183 checksum:

1.At the PORT OUTPUT SETUP screen, press the CURSOR PAD to high- light the 0183 SUM field, then press the EDIT key.

2.Press the CURSOR PAD to change the setting from ON to OFF.

3.Press the ACCEPT key (or press CANCEL to leave the option unchanged).

4.Press the RETURN key to go back to the PORT SETUP screen.

Setting the auxiliary port

The auxiliary (aux) port is a general-purpose port used to transmit differ- ential corrections (interfacing with an external device that accepts SC-104

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.
