1. MOUNTING

1.1Mounting Methods for Scanner Unit

•The scanner unit is generally installed ei- ther on top of the wheelhouse or on the radar mast on a suitable platform. Locate the scanner unit where there is a good all- round view. Any obstruction will cause shadow and blind sectors. A mast for in- stance, with a diameter considerably less than the width of the radiator, will cause only a small blind sector, but a horizontal spreader or crosstrees in the same hori- zontal plane as the scanner unit would be a much more serious obstruction; you would need to place the scanner unit well above or below it.

•It is rarely possible to place the scanner unit where a completely clear view in all directions is available. Thus, you should determine the angular width and relative bearing of any shadow sectors for their in- fluence on the radar at the first opportu- nity after fitting.

•If you have a radio direction finder on your boat, locate its antenna clear of the scan- ner unit to prevent interference to the di- rection finder. A separation of more than two meters is recommended.

•To lessen the chance of picking up elec- trical interference, avoid where possible routing the signal cable near other onboard electrical equipment. Also avoid running the cable in parallel with power cables.

•A magnetic compass will be affected if placed too close to the scanner unit. Ob- serve the following compass safe dis- tances to prevent deviation of a magnetic compass: Standard compass, 1.00 m, Steering compass, 0.75 m.

•Do not paint the radiator aperture, to en- sure proper emission of the radar waves.

•When this radar is to be installed on larger vessels, consider the following points:

•The signal cable run between the scan- ner and the display comes in lengths of 10 m (standard), 15 m, 20 m and 30 m. Whatever length is used it must be unbroken; namely, no splicing allowed.

•Deposits and fumes from a funnel or other exhaust vent can adversely affect the aerial performance and hot gases may distort the radiator portion. The scanner unit must not be mounted where the temperature is more than 70 C.

As shown in the figure below, the scanner unit may be installed on the bridge, on a com- mon mast or on the radar mast.

1.2Fixing Holes in Mounting Platform

Referring to the outline drawing on page D- 1, drill five holes in the mounting platform: four holes of 15 mm diameter for fixing the scanner unit and one hole of 25-30 mm di- ameter for the signal cable.

1932 MARK-2 specifications

The Furuno 1932 MARK-2 is a state-of-the-art radar system designed for maritime applications, providing exceptional performance and reliability. This advanced radar unit is renowned for its impressive range, superior target detection capabilities, and user-friendly interface, making it an essential tool for vessels of all sizes.

One of the standout features of the Furuno 1932 MARK-2 is its high-resolution display. The 10.4-inch color LCD screen offers crystal-clear visuals, enabling mariners to easily interpret radar data. With the capability to display 16 different colors, users can customize their views for enhanced clarity, allowing for better discrimination between targets and clutter. Additionally, the unit incorporates adjustable gain and clutter control, giving operators the ability to fine-tune the radar image to suit varying conditions, whether in busy harbors or open waters.

The 1932 MARK-2 utilizes a powerful 2.2 kW magnetron, allowing for excellent range performance. It can effectively detect targets up to 36 nautical miles away, providing mariners with ample warning of potential hazards. This long-range capability is complemented by advanced target tracking technologies, including ARPA (Automatic Radar Plotting Aid). This system enables users to monitor and track multiple vessels simultaneously, providing essential information such as course, speed, and distance for better situational awareness.

In terms of technology, the Furuno 1932 MARK-2 includes a Fast Target Update feature. This allows for rapid refresh rates, ensuring that moving targets are accurately displayed, even in heavy traffic areas. The unit also employs advanced digital signal processing to filter out noise and improve target detection, enhancing overall operational efficiency.

Another key characteristic of the 1932 MARK-2 is its robust build quality. Designed to withstand the marine environment, the unit features a waterproof casing with an IP55 rating, ensuring durability against splashes and humidity. Furthermore, its compact design offers versatile mounting options, making it adaptable for various vessel configurations.

Overall, the Furuno 1932 MARK-2 radar system stands out for its blend of advanced technology, user-centric features, and rugged reliability. Its ability to provide clear and accurate radar imagery makes it an invaluable asset for navigators, enhancing safety and efficiency on the water. As an investment in maritime technology, it offers significant advantages to enhance both recreational and commercial navigation.
