Output sentence limitation

The number of sentences which can be output depends on baud rate and output interval settings. The maximum number of characters per each data sentences are shown in the table below and the total number of characters must satisfy the formula shown below. The number of characters which can be output “N” is calculated by the following formula

N < 0.083 x T x B

T:Interval (s)

B:Baud rate

*: Output is 1 s if interval set is shorter than 1 s.

For example, the baud rate is 4800 bps, interval is 100 ms (= 0.1 s). Therefore, the number of characters is N <0.083 x 0.1(s) x 4800(bps) = 39.4.

Then, the number of characters which can be output is 39. For sentences (sentences not having an asterisk in the table) where the output interval is variable the number of characters is as shown in the table, however sentences where the output interval is not smaller than 1 s (asterisk-marked sentences in table) the number of characters which can be output is “number of characters in table” x “setting interval.”

For the above settings the following applies:

If both HDT and HDM are selected the total number of characters is 19+19 = 38. Since the count is less than 39 both can be selected.

If both HDT and VTG are selected the total number of characters is 19+46x0.1=23.6. Since the count is less than 39 both can be selected.

If HDT, HDM and VTG are selected the total number of characters is 19+19+46x0.1=42.6. In this case, the message “SENTENCE OVERLOAD” appears.

Furuno SC-110 manual Output sentence limitation, Sentence and maximum number of characters

SC-110 specifications

The Furuno SC-110 is a sophisticated marine navigation system designed for a wide array of maritime applications. This advanced device showcases Furuno’s commitment to quality and innovation, making it a popular choice among boat owners, commercial vessels, and maritime professionals.

At the heart of the SC-110 is its precise Positioning Differential GPS (DGPS) technology. This cutting-edge systems enhances the accuracy of standard GPS operations, enabling users to obtain real-time positioning with an impressive level of precision. The SC-110 offers positioning accuracy within one meter, vital for navigation safety and efficiency, particularly in congested or challenging maritime environments.

One of the standout features of the Furuno SC-110 is its built-in Automatic Identification System (AIS) capability. AIS technology allows the SC-110 to display real-time information about nearby vessels, including their position, course, and speed. This additional situational awareness helps mariners avoid potential collisions, making it an essential component for navigation in busy shipping lanes.

The device also incorporates a user-friendly interface, characterized by a sharp, high-resolution display that is easy to read in various lighting conditions. This ensures that maritime operators can access critical navigation data quickly and without confusion. Additionally, customizable settings allow users to tailor the system to their specific needs, improving overall usability.

Another significant aspect of the Furuno SC-110 is its robust integration capabilities. The system can seamlessly connect with other onboard electronic equipment, such as radar systems, chart plotters, and autopilots. This interoperability enhances operational efficiency, allowing mariners to control all their navigational tools from a singular platform.

The SC-110 is designed to withstand the rigors of the marine environment. Built with durable materials and an IP67 waterproof rating, it provides reliable performance even in harsh weather conditions. This resilience ensures that the system will serve maritime operators effectively over time without compromising functionality.

In summary, the Furuno SC-110 represents a blend of advanced technology and practical usability. Its high-precision DGPS, AIS integration, user-friendly interface, and robust construction make it an invaluable tool for safe and efficient maritime navigation. Whether for leisure boating or commercial operations, the SC-110 stands as a testament to Furuno’s expertise in the marine electronics field.
