Important Information
This handbook contains important information on the installation and
operation of your new equipment. In order to obtain the best results in
operation and performance, please read this handbook thoroughly.
Raymarine’s Product Support representatives, or your authorized dealer, are
available to answer any questions you may have.
Intended Use
Raymarine DS400 and DS500 Digital Fishfinders are intended for
recreational fishfinding.
EMC Conformance
All Raymarine equipment and accessories are designed to the best industry
standards for use in the recreational marine environment.
Their design and manufacture conforms to the appropriate Electromagnetic
Compatibility (EMC) standards, but correct installation is required to ensure
that performance is not compromised. Although every effort has been taken
to ensure that they will perform under all conditions, it is important to
understand what factors could affect the operation of the product.
The guidelines given here describe the conditions for optimum EMC
performance, but it is recognized that it may not be possible to meet all of
these conditions in all situations. To ensure the best possible conditions for
EMC performance within the constraints imposed by any location, always
ensure the maximum separation possible between different items of
electrical equipment.
For optimum EMC performance, it is recommended that wherever
possible:
• Raymarine equipment and cables connected to it are:
• At least 3 ft (1 m) from any equipment transmitting or cables carrying
radio signals, e.g., VHF radios, cables and antennas.
• More than 7 ft (2 m) from the path of a radar beam. A radar beam can normally be assumed to spread 20 degrees above and below the radiating element.
DS400 and DS500 Digital Fishfinders v
• Raymarine specified cables are used. Cutting and rejoining these cables
can compromise EMC performance and must be avoided unless doing so
is detailed in the installation manual.
• If a suppression ferrite is attached to a cable, this ferrite should not be
removed. If the ferrite needs to be removed during installation it must be
reassembled in the same position.
Safety Notices
1. PRODUCT INSTALLATION. This equipment must be installed and
operated in accordance with the instructions contained in this handbook.
Failure to do so could result in poor product performance, personal injury
and/or damage to your boat.
2. HIGH VOLTAGE. The display unit, transducer cable, and transducer
contain high voltages. Adjustments require specialized service procedures
and tools only available to qualified service technicians - there are no user
serviceable parts or adjustments.
3. NAVIGATION AID. This unit is only an aid to navigation. Its accuracy
can be affected by many factors, including equipment failure or defects,
environmental conditions, and improper handling or use. It is the user’s
responsibility to exercise common prudence and navigational judgments.
This fishfinder should not be relied upon as a substitute for such prudence
and judgment.
4. ULTRASONIC ENERGY. The transducer transmits high frequency
energy while in use. The unit should be turned off when swimmers or divers
are in close proximity to the transducer. (There is a lack of scientifically
sound standards or guidelines for exposure levels and limits to ultrasound.
This notice is precautionary only.)
WARNING:
Do not disconnect the transducer cable without first powering off the
display unit. Removal of the transducer cable from the DS400/500 while
power is turned on can cause sparks.

Chapter 1: Overview
1.1 Introduction
This handbook describes the DS400 and DS500 Digital Fishfinders. The
DS400/DS500 feature state-of-the-art High Definition Fish Imaging (HDFI)
technology. Constantly adjusting transmitter and receiver parameters, the
DS400/DS500 intelligently analyzes fish and bottom echoes and
automatically produces a crystal clear echo sounder display.

D6437-1
D6445-1
2 DS400 and DS500 Digital Fishfinders
The DS400/500 employs a very high transmission repetition or “ping” rate
which, along with the digital adaptive high sample rate receiver, ensures that
fish and bottom structure are presented in superb detail and optimal color
allocation. The DS400/500 digital bandwidth adaptation adjusts the receiver
band width dynamically from very wide to very narrow, as required by the
actual water conditions. This provides superior fish and bottom detection in
conditions where other fishfinders see very little or nothing at all.

2.3 Selecting the Equipment Location
Mounting Location
The DS400/500 is waterproof to IPX7 is and designed to be mounted either
above or below deck. The unit should be protected from physical damage and
excessive vibration.
CAUTION:
Mount the DS400/500 in a protected area away from prolonged
exposure to rain, salt spray, and direct sunlight, but well ventilated.
When planning the installation, the following should be considered to ensure
reliable and trouble free operation:
• Access: There must be sufficient space below the unit to enable cable
connections to the panel connectors, avoiding tight bends in the cable.
• Interference: The selected location should be far enough away from
devices that may cause interference, such as motors, generators, and
radio transmitter/receivers (see the EMC guidelines earlier in this section).
• Magnetic compass: Mount the unit at least 3 ft (1m) away from a mag-
netic compass.
• Cable runs: The unit must be located near a DC power source. The
power cable supplied is 5 ft (1.5 m), but a longer cable can be used if
desired. Refer to Section 2.4.
The maximum length of cable between the fishfinder and the transducer
unit should not normally exceed 25 ft (8 m). If you need to use a longer
cable, refer to Section 2.4.
• Environment: Good ventilation is required to prevent the unit from
overheating.
WARNING:
Removal of the transducer cable from the DS400/500 while power is
turned on can cause sparks. As with any electronic device, be sure the
fishfinder is mounted where it is well ventilated and free from gasoline
fumes.
8 DS400 and DS500 Digital Fishfinders
2.4 Cable Runs
Consider the following before installing the system cables:
• You will need to attach the power and transducer cables.
• All cables should be adequately secured, protected from physical dam-
age, and protected from exposure to heat.
Avoid running cables through bilges or doorways, or close to moving or
hot objects.
• Sharp bends must be avoided.
• Where a cable passes through an exposed bulkhead or deckhead, a water-
tight feed-through should be used.
• Secure cables in place using tie-wraps or lacing twine. Coil any extra
cable and tie it out of the way.
You will need to run the following cables:
• Power/NMEA cable, supplied with the unit. This 5 ft (1.5 m) cable has
a connector plug at one end for connecting to the fishfinder, and 3 wires at
the other end for connecting the power supply. The power cable may be
extended by up to 60 ft (20 m) using a wire gauge of AWG 12 or greater.
The DS400/500 is intended for use on the boat’s DC power systems
rated from 10-18 Volts DC (13.8V nominal).
• Transducer cable, supplied with the transducer. This 25 ft (8 m) cable
has a connector plug (with an outer nut that you must attach) at one end
for the display unit or extension cable. The transducer cable may be
extended up to a maximum of 60 ft (20 m) using optional extension
cables.
Cutting the transducer cable will severely reduce sonar performance:
• Do not cut the transducer cable or remove the connector.
• Do not shorten or splice the cable.
If the cable is cut, it must be replaced—it cannot be repaired.
Cutting the cable will also void the warranty.

• Transducer connection.
• Power, for 12 VDC power connection and NMEA connection.
D6459-1
Power/NMEATransducer
Figure 2-5: DS400/500 Connector Panel
The following sections detail the connectors used when installing the
DS400/500.
DC Power Connection
The DS400/500 is intended for use on the boat’s DC power systems rated
from 10-18 Volts DC (13.8V nominal).
The power connection to the unit should be made at either the output of the
battery isolator switch, or at a DC power distribution panel. Raymarine
recommends that power is fed directly to the DS400/500 via its own
dedicated cable system.
A 2 amp, fast blow fuse is attached (in-line) to the red (positive) wire.
A 5 ft (1.5 m) Power/NMEA cable is supplied for connecting the boat’s DC
power to the unit. The Power/NMEA cable may be extended by up to 60 ft
(20 m) using a wire gauge of AWG 12 or greater.
DC power is connected at the seven-pin Power/NMEA connector on the
unit’s connector panel. The connector (viewed from the outside) and pin
functions are shown in the following diagram and table.

The RED wire must be connected to the feed from the positive (+) battery
terminal and the BLACK wire to the feed from the negative (–) battery
terminal.
A fast blow 2 amp fuse is installed in-line on the red (positive) wire.
CAUTION:
If the power connections are accidentally reversed the system will not
work. Use a multimeter to ensure that the input power leads are
connected for correct polarity.
Transducer Connection
A 25ft (8m) cable is supplied with the transducer. The transducer cable
connector has a nut that has been removed to aid installation. To enable you
to complete the installation without cutting the cable, ensure that any holes
you drill are large enough to accept the connector, with the nut removed
(approximately 13/16" or 21 mm).
Before attaching the transducer cable, you will need to attach the connector
nut, which is included in the transducer packaging.
The transducer cable is attached to the 7 pin male TRANSDUCER connector on
the connector panel of the DS400/500. (See Figure 2-5 .)
CAUTION:
• Do not pull on the cable. This can damage the transducer wires.
• Do not cut the transducer cable or remove the connector.
• Do not try to shorten or splice the cable. Cutting the transducer cable will
severely reduce sonar performance.
Chapter 2: Installation 15
• If the cable is cut, it must be replaced—it cannot be repaired. Cutting the
cable will also void the warranty.
WARNING:
Removing the transducer cable from the rear of the DS400/500 while the
fishfinder is powered on can cause sparks. Only remove the transducer
cable after power has been removed from the DS400/500.
If the transducer cable is accidentally removed while the DS400/500 is
powered on, remove power from the fishfinder, replace the transducer
cable, and then restore power. As a safety feature, the DS400/500 only
recognizes that the transducer is connected at power-up.

installation.
CAUTION: NEVER USE SOLVENTS
Cleaners, fuel, paint, sealants, and other products may contain strong
solvents, such as acetone, which attack many plastics greatly reducing
their strength.
Applications
• Not recommended for boats with large or twin screw inboard engine(s)
• Requires 89mm (3-1/2") of headroom to install
• Good operation up to 44kts (50MPH)
• Vertically orients sound beam on hull with deadrise angle up to 30°
• Adjusts to transom angles from 2°– 22°
• Bracket protects multisensor from frontal impact only

Pretest
Connect the multisensor to the instrument and spin the paddlewheel. Check
for a speed reading and the approximate air temperature. If there is no reading
or it is inaccurate, return the product to your place of purchase.

Mounting Location
For the best performance, the transducer must be in contact with aeration-free
and turbulence-free water. Mount the transducer on the transom as close to
the centerline (keel) of the boat as possible. On slower heavier displacement
hulls, positioning it farther from the centerline is acceptable.
Do not mount in an area of turbulence or bubbles:
• Near water intake or discharge openings
• Behind strakes, struts, fittings, or hull irregularities
• Behind eroding paint (an indication of turbulence)
CAUTION:
Avoid mounting the transducer where the boat may be supported
during trailering, launching, hauling, or storage.
• Single drive boat—Mount the transducer on the starboard side at least
75mm (3") beyond the swing radius of the propeller (see Figure 2-7 ).
• Twin drive boat—Mount the transducer between the drives.

Installation
Assembling
1. Insert the transducer’s pivot posts into the recesses on the sides of the
bracket (see Figure 2-8 ).
2. Press the two nuts into the slots in the back of the bracket.
3. Aligned the holes in the transducer, bracket, and nuts. Insert the two
machine screws capturing the nuts. Tighten the machine screws until the
transducer will stay in the “up” (released) position unaided.

Marking and Hole Drilling
1. At the selected location on the starboard side of the hull, position the
transducer, so the transducer projects 3mm (1/8") below the bottom edge
of the transom (see Figure 2-10 ).
2. Being sure the bottom of the transducer is parallel to the waterline, mark
the location of the screw holes with an “X” in the center of the two outer
most slots.
CAUTION: Always wear safety goggles and a dust mask.
3. Using a 4mm, #23, or 9/64" drill bit, drill two holes 22mm (7/8") deep at
the locations indicated. To prevent drilling too deeply, wrap masking tape
around the bit 22mm (7/8") from the point.
Fiberglass hull—Minimize surface cracking by chamfering the gelcoat.
If a chamfer bit or countersink bit is not available, start drilling with a
6mm or 1/4" bit to a depth of 1mm (1/16").
Plastic Shim
• Standard transom (13° transom angle)—The bracket is designed for a
standard 13° transom angle. The shim is not needed for this installation.
Skip to Mounting the Bracket.
• Stepped transom and jet boats (3° transom angle) —Use the shim with
the tapered end down. Be sure the nuts are in the slots in the back of the
bracket before applying the shim (see Figure 2-8 ).
• Small aluminum and fiberglass boats (20° transom angle)—Use the
shim with the tapered end up. Be sure the nuts are in the slots in the back
of the bracket before applying the shim (see Figure 2-8 ).
• If you are unsure about using the shim, do one of the following:
• Measure the transom angle of your boat using a digital level or bubble
level and protractor. Then follow the instructions above for your transom angle.
• Experiment with the shim by following the instructions Mounting
the Bracket and Checking the Angle and Projection.
Mounting the Bracket
1. Apply marine sealant to the threads of two, #10 x 1-3/4", self-tapping
bracket screws to prevent water seepage into the transom.
2. Screw the transducer (with the shim if needed) to the hull (see Figure 2-10
). Do not tighten the screws at this time.
