Connection of external power supply

An external power supply is necessary when the repeater signal is step-by-step type and the step voltage is below 20V or output voltage is less than 5 W.

1.Cut jumper wire JP1 on the GYRO CONVERTER Board when an external power supply is used.

2.Connect gyro cable and power cable as shown below.

DIP switch, jumper wire settings

Default setting

The default setting of all DIP switches is off and all jumpers wire are set to “#1.” (Note that jumper wire JP1 is set at #1, #2, and #3.) In those settings the gyrocom- pass having the following characteristics can be directly connected; modification of the GYRO CONVERTER Board is not necessary.

AC synchronous signal: 50/60 Hz

Rotor voltage: 60 V to 135 V AC

Stator voltage: 60 V to 135 V AC

Gear ratio: 360x

Supply voltage: 30 V to 135 V AC

If the specifications of the gyrocompass differ from those mentioned above, change jumper wire and DIP switches settings on the GYRO CONVERTER Board. Set- tings may be changed according to gyrocompass specifications or make and model of gyrocompass (see page 4-5). For the location of DIP switches and jumper wires, see page 4-6.

One of the standout features of the FR-2155 is its high-definition display, which offers a crystal-clear view of radar images. The 15-inch LCD screen provides an easy-to-read presentation of targets, weather conditions, and navigational information. The display is designed to be sunlight-readable, ensuring clear visibility even in bright conditions.

The radar utilizes Furuno's advanced Doppler technology, which allows users to track moving targets accurately. This feature enhances collision avoidance efforts by providing real-time information on the speed and direction of approaching vessels, making it easier to assess potential risks. Moreover, the FR-2155 incorporates an Automatic Radar Plotting Aid (ARPA) function that automatically tracks up to 50 targets, allowing operators to concentrate on navigating rather than manually monitoring multiple targets.

Another remarkable characteristic of the Furuno FR-2155 is its ability to operate in various weather conditions. The radar system can filter out rain, sea clutter, and other interference, ensuring a clear image of surrounding objects. This feature is especially beneficial in adverse weather, where visibility is often compromised, thereby enhancing safety during challenging navigation scenarios.

Connectivity is crucial in modern maritime operations, and the FR-2155 excels in this regard by offering various integration options for onboard systems. It can seamlessly connect with GPS, AIS, and other navigation systems, providing a comprehensive overview of the vessel's environment. Additionally, the radar is capable of outputting data to chart plotters and electronic displays, consolidating critical information for the crew.

In terms of installation, the Furuno FR-2155 is designed for versatility. Its compact design allows for flexible mounting options, accommodating different vessel layouts without compromising performance. The radar also features a powerful magnetron that ensures long-range detection capabilities, effectively covering vast areas of water.

In summary, the Furuno FR-2155 marine radar system stands out due to its high-definition display, Doppler technology, automatic target tracking, and excellent clutter rejection. Its ability to integrate seamlessly with other navigation tools and its user-friendly design make it an invaluable asset for any vessel, ensuring safety and efficiency on the water. For those looking for a reliable radar solution, the FR-2155 is certainly worth considering.
