4.6 Connection of Interface Unit CS-120A

With connection of navigator, the Interface Unit CS-120A and electronic fishing equipment, the function of the CSH-23/24 series is expanded to include true motion presentation, target lock, echo sounder picture, FNZ marker presentation and digital indication of position, water temperature and depth. This chapter provides the information for interfacing the CSH-23/24 series with external equipment.

Connections for true motion and target lock

Heading (digital) and speed (200 pulses/nm) data are required to provide the true motion and target lock functions. Both data are fed to the display unit via Interface Unit CS-120A.

Basically, there are three methods to feed the data:

Heading data is fed to J205 from A/D Converter AD-100 and the speed pulse data to J206 from the speed log.

Both heading and speed data are fed to J207 or J204 from the CIF line of the CI-30/50/60.

NMEA signal is fed to J208 (NMEA port) or J207 (CI/NMEA port).

CSH-24F, CSH-23F, CSH-23, CSH-24 specifications

Furuno, a leader in marine electronics, has developed a range of advanced marine radar systems known as the CSH series. The CSH-24, CSH-23, CSH-23F, and CSH-24F are particularly notable for their innovative technologies, designed to enhance navigational safety and operational efficiency for vessels of various sizes.

The CSH-24 and CSH-23 models are known for their impressive 24 GHz and 23 GHz frequency bands, offering high-resolution imagery and enhanced target detection capabilities. These radars utilize Furuno’s digital signal processing technology, which significantly improves target discrimination, even in cluttered environments. This feature is invaluable for navigational safety, especially in busy waterways or coastal areas.

One of the key highlights of the CSH series is its advanced Automatic Radar Plotting Aid (ARPA) functionality, which enables the proactive monitoring of marine traffic. With the ability to track multiple targets simultaneously, mariners can make more informed decisions, avoiding potential collisions and ensuring smoother navigation. Additionally, the systems provide enhanced Tracking History that allows users to analyze target movements over time.

The CSH-24F and CSH-23F models incorporate Furuno's cutting-edge features, including Fast Target Tracking and Target Predictive Motion, which further enhances reactive capabilities. These radars also offer an intuitive user interface, making it easy to operate and customize settings to fit specific navigational requirements. The displays are designed for readability, even under challenging lighting conditions, thanks to advanced anti-glare technologies.

Built with ruggedness in mind, the CSH series is designed to withstand harsh marine environments. The robust construction and weatherproof design ensure that the systems perform reliably, regardless of sea conditions. Moreover, these radar systems are compatible with a range of marine integration options, allowing for seamless connectivity with other onboard navigation equipment.

In summary, the Furuno CSH-24, CSH-23, CSH-23F, and CSH-24F radars embody a blend of advanced technology, robust design, and user-friendly interfaces. These systems stand out in the marine electronics market for their reliability and precision, making them an excellent choice for maritime professionals seeking enhanced safety and efficiency on the water.
