General Information about DRS2D-NXT/DRS4D-NXT
Note: Most of the figures in this manual are based on the DRS4D-NXT. Layouts may be slightly
different if you have the DRS2D-NXT.
• TARGET ANALYZER™function* displays targets that are moving and getting close to own ship
in red and other targets in different colors. Speed analyzing range is ±50 kn.
*: Requires a GPS sensor. When you change the setting of [Target Analyzer Mode] to [Rain],
rain clutter is displayed.
• AUTO TARGET ACQUIRE function automatically acquires only the targets which are moving
and getting close to own ship within the range of 3 NM by Doppler calculation. Automatic Dop-
pler function will be activated when there is a target which approaches own ship with the speed
of over 3 kn*.
*: The judged speed of target is dependent on its vector towards own ship.
• RezBoost™provides azimuth resolution equivalent to comparable open-array radar.
Note: Refer to the Operator‘s Manual for your Multi Function Display regarding the above new
functions.
• Instant ON function. This radar sensor does not have a magnetron, therefore preheating of the
magnetron is unnecessary.
• Retrofit from DRS2D, DRS4D or DRS6A is available using the existing cable.
Refer to the following document, supplied with the optional kit OP03-239: "Retrofit Procedures
for DRS2D-NXT/DRS4D-NXT (Type; C32-01501-x/;Code no.; 000-191-116-xx).
• 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 is shown as a line.
• The maximum display range is 48 NM in the single range mode.
• ARPA* (Automatic Radar Plotting Aid) function applicable range is 12 NM.
*: ARPA symbols are erased when switching between single and dual range modes and vice
versa.
• Dual Range Mode has the following limitations.
- The maximum display range is 12 NM. (48 NM when single display)
- The maximum detection range is reduced a maximum of 20% compared to the single
display.
FOREWORD

1. INSTALLATION
1.1 Installation Considerations
• Do not paint the radome, radar wave emission may be affected.
• Do not select a location that allows water to accumulate at the base of the sensor.
• Do not cut power/LAN cable or cable assembly when installing.
• Do not block air vent at the bottom of radome.
Connect to a distribution switchboard
• The radar sensor has no power switch. Connect the sensor to a distribution switch-
board 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 a horizontal (360°) and a vertical (25°) beam.
Place the sensor where there is a good all-round view as far as possible and no part
of the ship‘s superstructure or rigging intercepting the scanning beam. Any small
obstruction causes not only shadows and blind sectors, but also the deterioration of
antenna ability, such as beam width and side-lobe level. It also reduces the radar's
functionality, for example azimuth resolution, and may cause false echoes. 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 ob-
struction; 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 on the following
page for typical placement on a sailboat and powerboat.
• Install the radar where large structures, such as a mast, will not be within 1 m diam-
eter from the center of radar.
• Select a location free of structures as much as possible, in order to avoid causing
blind sector. A blind sector within the radar beam may prevent proper display of ra-
dar echoes.
NOTICE
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.

• 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 installation.
• The radar sensor should not be operated or stored in any position other than the
proper operational position (upright).
Consideration for selecting a location for installation (multiple radars)
• In case multiple radars are installed on a ship, DO NOT install the DRS2D-NXT/
DRS4D-NXT within the range of beam area emitted from other radar(s). Use the il-
lustration below for reference when selecting a suitable location for installation. The
SSD inside the RS4D-NXT will be damaged if it is within the radar beam emission
area from other radar.

Installation with the radiotelephone equipment
• Install the radome away from radiocommunication antennas (SSB, VHF, Inmarasat)
and GPS antenna to prevent radar interference.
• Install the radome away from the radiotelephone equipment so that electrical noise
does not affect the radiotelephone equipment.
Cable routing
• In order to reduce the chance of picking up electrical interference, avoid, where pos-
sible, routing the power/LAN cable and cable assembly near other electrical equip-
ment on-board. Also, avoid running the cable in parallel with other electrical cables.
• Make sure that the power/LAN cable and cable assembly do not run horizontally
and it is placed 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/LAN cable is 1 m from radome to the con-
nector. The supplied cable assembly which runs between the radar sensor, pow-
er supply and display comes in lengths of 10 m, 15 m, 20 m or 30 m. Select the
length when purchasing.
• 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 sen-
sor must not be mounted where the temperature is more than 55°C (131°F).
1.2 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 up-
dated 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 to the right.
• A wrench for M10 bolts
• An electric drill with φ11 mm (0.43‘‘) drill bit
Installation on a platform
There are 5 steps necessary to install the radar sensor. The illustration below summa-
rizes the installation.

How to align the antenna heading
You have mounted the antenna unit facing straight ahead in the direction of the
bow. Therefore, a small but conspicuous target dead ahead visually should ap-
pear on the heading line (zero degrees).
In practice, you will probably observe some small bearing error on the display be-
cause of the difficulty in achieving accurate initial positioning of the antenna unit.
The following adjustment will compensate for the error.
1) Select a range between 0.125 and 0.25 NM and set the mode to ‘‘head up‘‘
You can select a range by a pinch action. The range and range ring interval
appear at the bottom left of the screen.
