Adjustment of signal level (R36, R56)

1.Set the MODE switch to E/S.

2.Turn the potentiometer R36 to suppress a noise, and the potentiometer R56 so that the color gradation of the E/S picture on the screen appears similar to the intensity gradation of the combined E/S echogram.

Adjustment of white line inhibit time (R27)

In case digital depth data is not combined with the CS-120A, the white line signal from the echo sounder is used for depth information. Potentiometer R27 cancels the white line pulse for about 10 ms after transmission to avoid false depth indication caused by unwanted noise in short ranges. Readjustment of potentiometer R27 is not required as long as CSH-23/24 series indicates the correct depth. If does not, however turn R27 to the right.

Adjustment of white line output level (R55)

Improper setting of potentiometer R55 causes the seabed line to be painted in deep blue due to the white line pulse. Adjust it so that the seabed line is painted in same color as seabed.

Priority for data

The priority between ports, the category of data or formats is as follows. “1” has the highest priority.

Basic priority

1.NMEA data > CIF data

2.NMEA data: NMEA port data > CI/NMEA port data

3.CIF data: CI/NMEA port data > CIF port data

Heading priority

1.Heading data from GYRO 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.
