SECTION FOUR - Service/Maintenance

Configuring the receivers

Processor serial number and software revision

The serial number of the processor is affixed to the back of the unit, and also has been permanently programmed into the unit’s database. You can view this serial number at the PRODUCT INFORMATION screen in the PROCESSOR SN/REV field.

Serial numbers ending with the letter D indicate that the unit contains an internal DGPS differential receiver.

Beacon receiver self-test and software revision

The 961 automatically self-tests the internal beacon receiver, if installed, each time you power-up the unit. The BCN RCVR ST/ REV field displays the software version used by your 961’s DGPS receiver (if installed), as well as the self-test message PASS or FAIL. If all test parameters are met, the field says PASS. If the differential receiver fails any of the test criteria, the field says FAIL. If the field says FAIL, the 961 won’t be receiving DGPS signals; for details about troubleshooting the DGPS receiver, see ”Testing and troubleshooting the 961” beginning on page 32. In many cases, the reason for the failure is an open or shorted antenna cable, which can be repaired in the field. If this isn’t the source of the failure, call the North- star Service Department for further instructions.

If a beacon receiver isn’t installed, this field is blank.

GPS receiver self-test and software revision

The GPS RCVR ST/REV field displays the software version used by your 961’s GPS receiver, as well as the self-test message PASS or FAILED. This field should read PASS, not FAIL. If the 961 displays the message FAIL, return the 961 to Northstar for service.

The 961’s RECEIVER INFORMATION screen provides you with access to several of the 961’s GPS and DGPS (if installed) receiver functions. To dis- play these functions, press the STAR key until you reach the SERVICE MENU screen, then press the RECEIVER SETUP key.

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.
