INSTALLATION
1.1
General Information about DRS4D-NXT
• ECHO ANALYZER function, the first model in the world to achieve with marine radar, to display rain clutter, moving objects (approaching/ moving away) and static
objects with different colors.*
* Requires heading sensor and GPS sensor.
• ACCU-SHIP function, the first model in the world to achieve with marine radar, to
automatically acquire only the moving objects by doppler velocity and display other
ships and their traces with large/medium/small icons.
* The judged speed of objects is dependent on its vector towards own ship.
• RezBoost function achieved high-azimuth resolution, the same as open-array radar.
• Instant ON function.
• No radiation hazard to look out for.
• No need to worry about the life of magnetron or to replace any parts periodically.
• Retrofit from DRS2D, DRS4D and DRS6A is available with using the installed cable.
Refer to Chapter 4 for retrofit.
• RACON (RAdar beaCON) and SART (Search And Rescue Transponder) within 0.5
to 1.5 NM (Range dependant) can be displayed.
* The signal from RACON and SART will be shown as a line.
• ARPA (Automatic Radar Plotting Aid) function applicable range varies according to
the range scale. 12 NM when display range is less than 1 NM. 24 NM when display
range is larger than 1.5 NM. * Changing the display range may lose the ARPA symbols.
• Dual Range Mode sets below limitations.
• The maximum display range is 12 NM. (32 NM when single display)
• Echo Analyzer function becomes unselectable.
• The maximum detection range lowered by 20% at the maximum comparing to the
single display.
1.2
Installation Considerations
Don’ts to Avoid Damages to the Radome and Connectors
• Do not apply paint, anti-corrosive sealant or contact spray to coating or plastic parts
of the equipment. Those items contain organic solvents that can damage coating
and plastic parts, especially plastic connectors.
• Do not paint the radome, its emission of the radar waves may be deteriorated.
• Do not select a location that allow water to accumulate at the base of the sensor.
• Do not cut pre-attached cable or selectable power/Network cable when installing.
1. INSTALLATION
Connect to a Distribution Switchboard
• The radar sensor has no power switch. Therefore, it is recommended that you connect the sensor to a distribution switchboard with a switch for power control.
Considerations for Selecting a Location for Installation
• Install the radar sensor on radar arch, on a mast or on an appropriate platform.
For sailboats, a “radome mount” is optionally available for installing the sensor to
a mast.
• This radar sensor emits horizontal (360°) and vertical (25°) beam.
Horizonal and vertical Beam Width of DRS4D-NXT
12.5°
12.5°
12.5°
12.5°
Place the sensor where there is a good all-round view with, as far as possible,
no part of the ship’s superstructure or rigging intercepting the scanning beam. Any
small obstruction causes not only the shadow, an blind sectors, but also the deterioration of antenna ability, such as beam width, side-lobe level. It also worsens the
radar functionality, such as azimuth resolution and occurrence of the false echo. A
mast for instance, with a diameter considerably less than the horizontal beam width
of the radiator, causes only a small blind sector, but a horizontal spreader or cross
trees in the same horizontal plane as the radar sensor would be a much more serious obstruction; you would need to place the radar sensor well above or below it.
Be sure there are no metallic objects near the antenna. See illustrations below for
typical placement on a sailboat and powerboat.
• It is rarely possible to place the radar sensor 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 influence on the radar at the first opportunity
after fitting.

1. INSTALLATION
Consideration for Selecting a Location for Installation (Multiple Radars)
• In case multiple radars are installed on a ship, DO NOT install the DRS4D-NXT
within the range of beam area emitted from other radar(s). See below illustration for
the suitable place to install the DRS4D-NXT. The SSD of DRS4D-NXT will be damaged if it is within the radar beam emission area from other radar.
Radar beam emission area from

Suitable location for installing
the DRS4D-NXT
Installation with the Radiotelephone Equipment
• Install the radome away from the radiotelephone equipment, VHF antennas, GPS
antennas and Inmarsat dome so that the emission beam from the radome not obstructed.
• Install the radome away from the radiotelephone equipment so that the radiotelephone equipment do not pick up electrical noise.
Cable Routing
• In order to reduce the chance of picking up electrical interference, avoid where possible routing the power/Network cable near other electrical equipment on-board. Also, avoid running the cable in parallel with other electrical cables.
• Make sure that the power/Network cable does not run horizontally and it is put away
from the cables carrying radio signal and antennas.
For Large Vessels
• When this radar sensor is to be installed on a large vessel, consider the following
points:
• The length of the pre-attached power/Network cable is 1 m from radome to the
connector.
• The length of the standard supply power/Network cable is 15 m from the connector to the power supply and display.
• The power/Network cable which runs between the radar sensor and power supply
and display comes in lengths of 10 m, 15 m, 20 m or 30 m. Select the length when
purchasing.
1. INSTALLATION
• 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 radar sensor must not be mounted where the temperature is more than 55°C (131°F).
1.3
Installation of the Radar Sensor
Determine the suitability of the mounting location BEFORE permanently mounting the
sensor. Incoming and outgoing signals may overlap one another depending on the
shape of the vessel, preventing communication between the radar and display. Set the
sensor on the selected location and connect the sensor to the distribution switchboard
and display unit. Turn on the sensor and the display unit. Check that the picture is updated with each sweep on the display unit. Some trial and error may be necessary to
find a suitable location.
Required tools for installation
Prepare the tools shown below.
• A wrench for M10 bolts
• An electric drill with 11 mm (0.43”) drill bit
Installation on a platform
There are 6 steps to proceed for installing the radar sensor to the selected location.

5. Connect the power/Network cable pre-attached to the radar sensor to the power/
Network cable.
Follow this guidelines for laying the power/Network cable
• The connectors must not strike any part of the vessel by wind, etc.
• Do not apply any load to the connectors.
• If the cable is passed through a mast on a sailboat, be sure the cable does not
touch ropes (sheet, halyard, etc.).
• Do not let the cable touch the hull.
1. INSTALLATION
• The cable must be located where no tension is applied to the connectors. To
prevent tension, create a loop in the cable close to the sensor and tie the loop
with cable ties, as in the figure below.
The minimum
bend diameter
is 80 mm.
Loop cable and tie loop with cable ties.
• Wrap the junction of the connectors with self-vulcanizing tape for waterproofing.
