Purpose

Raymarine DSM300 Digital So under Modules provide echo sounder data that ca n be displayed on Raymarine E Series, C Series, and hsb display units.

DSM300 Digital Sounder Modules are intended for recreational depth finding and fishfinding purposes. Echo sounder systems require an appropriate Raymarine transducer unit and inter-connecting cable.

This manual contains very important information for installing your DSM300 and transducer. To obtain the best results in operation and performance, please read this handbook thoroug hly. Raymarine’s Technical Services representatives or your local dealer will be available to answer any questions you may have.

SAFETY NOTICE

This equipment must be installed and operated in accordance with the instructions contained in this manual. Failure to do so can result in personal injury and/or navigational inaccuracies. In particular:

CAUTION: High Voltage

The DSM300 contains high voltages. Adjustments require specialized service procedures and tools only available to qualified service technicians – there are no user serviceable parts or adjustments. The operator should never remove the cover or attempt to service the equipment.

PLUS (Pathfinder) Series

CAUTION: Transducer Cable

Removing the transducer cable from the rear of the DSM300 while the sounder module is powered on can cause sparks. Only remove the transducer cable after power has been removed from the DSM300. As with any electronic device, be sure the sounder module is mounted where it is well ventilated and free from gasoline fumes.

If the transducer cable is accidentally removed while the DSM300 is powered on, remove power from the sounder module, replace the transducer cable, and then return power to the module. As a safety feature, the DSM300 only recognizes that the transducer is connected at power-up.

Chapter 1: DSM300 Installation

1.1 Introduction

This chapter provides details for mounting the DSM300 and connecting to the display.

For the system to display depth, water temperature and speed, you must install the transducer type(s) capable of transmitting the appropriate data. Transducer information is provided in Chapter 2.

Planning the Installation

Before you install your system, plan the installation, considering:

• Correct transducer for your application, as described in Section 2.1

• Location of the sounder module, as described in Section 1.3

• Cable Runs, as described in Section 1.5

EMC Installation Guidelines

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 descri be the conditions for optimum EMC performa nce, b ut it i s r ec o gn iz e d t ha t it ma y n ot b e p os si bl e t o m ee t a ll o f t he s e c on di ti o ns in a ll 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 5 ft (1.5 m) from any equipment transmitting or cables carrying

radio signals, e.g., VHF radios, cables and antennas. In the case of SSB radios, the distance should be increased to 7 ft (2 m).

Page 8

8 DSM300 Installation Manual

• 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.

• The equipment is supplied from a separate battery from that used for engine start. Voltage drops below 10 V and starter motor transients can cause the equipment to reset. This will not damage the equipment, but may cause the loss of some information and may change the operating mode.

• 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.

Suppression Ferrites

The following illustration shows typical cable suppression ferrites used with Raymarine equipment. Always use the ferrites supplied by Raymarine.

D3548-3

Figure 1-1: Typical Suppression Ferrites

Connections to Other Equipment

If your Raymarine equipment is to be connected to other equipment using a cable not supplied by Raymarine, a suppression ferrite must always be attached to the cable that is closest to the Raymarine unit.

1.3 Selecting Sounder Module Mounting Location

The DSM300 is waterproof to IPX-7 is and is designed to be mounted either above or below deck.

Mount the DSM300 where it is:

• protected from physical damage and excessive vibration

• protected from prolonged exposure to rain, salt spray and direct sunlight

• well ventilated

• as close to the transducer as possible

Do not locate the DSM300:

• in the engine compartment

• on the main console

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 con-

nections 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 chapter.)

•

Magnetic compass: Moun t the unit at least 3 ft (1 m) away from a magn etic

compass.

•

Cable runs: The unit must be located near a DC power source. The power

cable supplied is 10 ft (3 m).

•

Environment: Good ventilation is required to prevent the unit from over-

heating.

CAUTION: Do Not Remove the Transducer Cable Removing the transducer cable from the DSM300 while power is turned on can cause sparks. As with any electronic device, be sure the sounder module is mounted where it is well ventilated and free from gasoline fumes.

1.5 Cable Runs

Consider the following before installing the system cables:

• You will need to attach power, transducer, and display cables.

• All cables should be adequately secured, protected from physical damage,

and protected from exposure to heat.

• Avoid running cables through bilges or doorways, or close to moving or hot objects.

• Avoid sharp bends.

• Use a watertight feed-through wherever a cable passes through an exposed

bulkhead or deckhead.

• 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 cable, supplied with the unit. This 10 ft (3 m) cable has a connector

plug at one end for connecting to the sounder module, 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 DSM300 is intended for use on boat’s DC power systems rated from 10.7 V to 32 V.

•

Display cable, used to connect the DSM300 to a display unit. A 3m-long

cable is included for connecting to a C Series display. Connection cables for E Series or hsb be purchased separately. See Table 1-1 “Cable Options“ on page 9 for a list of available display cables.

•

Trans ducer c able, supplied with the transducer. This 30 ft (10 m) cable has

a connector plug (with an outer nut that you must attach) at one end for the sounder module or extension cable. Optional extension cables are listed in Table 2-1 “Accessories“ on page 25.

PLUS (Pathfinder) Series displays, or longer C Series cables, must

CAUTION: Do Not Cut or Splice the Transducer Cable

• There is high voltage on the transducer cable. Splicing could create a safety hazard.

• Cutting the transducer cable severely reduces sonar performance. If the cable is cut, it must be replaced—it cannot be repaired.

• Cutting the transducer cable will void the warranty and invalidate the European CE mark.

D7464-1

The following sections detail the connectors used when installing the DSM300.

DC Power Connection

The DSM300 is intended for use on boat’s DC power systems rated from 10.7 V to 32 V.

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. Power should be fed directly to the DSM300 via its own dedicated cable system and protected by a thermal circuit breaker or fuse on the red (positive) wire that is installed close to the power connection.

DC power is connected at the 3-pin POWER connector on the unit’s connector panel. The connector (viewed from the outside) and pin functions are shown in the following diagram and table.

Page 16

16 DSM300 Installation Manual

D6162-1

Figure 1-6: Power Connector

Pin No. Function Color

1 Battery positive (12/24/32 V systems) Red

2 Battery negative Black

3 Shield (drain wire) No insulation

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. The shield wire (drain) should be connected to the boat’s RF ground. See “Ground Connection” on page 17.

Install a quick blow 8 amp fuse 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.

There is no power switch on the DSM300. The unit turns on when the power cord is attached to boat’s power and plugged into the POWER connector on the connector panel.

Note:

You should locate the DSM300 so that the power cord can be easily removed, if necessary. If the sounder is placed in a difficult-to-reach location, Raymarine strongly suggests installing an on/off switch on the DSM300 power cord at a point where it is easily accessible.

Page 17

Chapter 1: DSM300 Installation 17

Transducer Connection

A 30 ft (10m) cable is supplied with the transducer. For details see “Tra ns du ce r Cable” on page 26. The connector pins are shown in the following diagram, together with the connections and wire colors; this is information is provided as an aid to fault diagnosis.

Pin No Function Color Pin No Function Color

1 Speed Red 5 Speed/Temp Ground Brown

2TempWhite 6+ Depth Blue

3ShieldDrain 7– Depth Black

4 Sense Green

Ground Connection

It is important that an effective RF ground is connected to the system. A single ground point should be used for all equipment. You can ground the DSM300 by connecting the drain wire (shield) of the Power Input cable to the boat’s RF ground. If you need to extend the wire, the extension wire should be an 8 mm braid or AWG 10 multi-stranded cable.

If your boat has a dedicated ground strap available, you can alternatively attach it to the ground wing nu t on the rear panel of the module. If your boat do es not have an RF system, connect the drain wire to the negative battery terminal.

The DC system should be either:

• Negative grounded, with the negative battery terminal connected to the boat’s ground.

• Floating, with neither battery terminal connected to the boat’s ground.

2.2 Transducer Cable

A 30 ft (10m) cable is supplied with the transducer. The transducer cable may be extended up to a maximum of 60 ft (20 m) using optional extension cables.

The transducer cable connector has a nut that has been removed to aid installation. To allow 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.

After the cable has been run through the holes, this nut must be attached before the cable can be connected, as described in

CAUTION: Do Not Splice the Cable Do not cut the transducer cable or remove the connector. Do not try to shorten or splice the cable. If the cable is cut, it cannot be repaired. Cutting the cable will also void the warranty.

• For a Transom mount installation – route the cable up and over the top edge of the transom as shown in Figure 2-2 . Secure the cable using cable clamps (available from your local marine equipment supplier).

If you do not want to expose the cable on deck, you may drill a hole 13/16" (21 mm) through the transom for the cable (with connector attached). To seal the opening, use a feed-thru cap where the cable passes through the transom.

• For either type of installation – run the cable through the interior of the boat.

• If the 30 ft (10 m) cable is not long enough, extension cables are available

from your Raymarine dealer. See Table 2-1 on page 25. Total cable length from the transducer to the DSM must not exceed 60 ft (20 m). When you attach the extension cable, be sure that the connections are watertight. Use Dow Corning DC-4 or an equivalent sealing compound to protect the connector assemblies.

CAUTION: Do not pull on the cable as this can damage the transducer wires.

Transducer Cable Connections

The transducer cable connector (and Y-connector, if supplied) has a nut that has been removed to aid installation. To allow 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 21mm).

28 DSM300 Installation Manual

The transducer cable is attached to the 7 pin male connector on the DSM. How you connect the cable to the unit depends on the type of transducer you have installed:

•

Combined depth/speed/temp transducers have a 7 pin female connec-

tor. Attach the transducer cable connector directly to the sounder module.

•

Combined speed/temperature transducers have a 3 pin female con-

nector that requires the use of an additional Y-shaped cable (Raymarine part number E66022) to attach to the 7 pin connector on the DSM300. This Y-cable is included with your speed/temperature transducer.

Attach the 7 pin female connector on the Y-cable to the sounder module, and then attach the transducer cable to the 3 pin male connector on the Y-cable.

•

Depth-only transducers have a 7 pin female connector.

Attach the transducer cable connector directly to the sounder module. If being installed in conjunction with a speed/temperature transducer, attach

the Y-cable’s 7 pin female connector to the sounder module, and then attach the transducer cable to the 7 pin male connector on the Y-cable.

Note:

If your syste m requires both a Y-cab le and a transducer extens ion cable, ensure that

you connect the Y-cable to the sounder module and the extension cable to the transducer.

CAUTION: Do not cut or splice the transducer cable:

• There is high voltage on the transducer cable. Splicing could create a safety hazard.

• Cutting the transducer cable severely reduces sonar performance. If the cable is cut it must be replaced, not repaired.

• Cutting the transducer cable will void the warranty and invalidate the CE mark.

CAUTION: Removing the Transducer Cable

Removing the transducer cable from the rear of the DSM300 while the sounder module is powered on can cause sparks. Only remove the transducer cable after power has been removed from the DSM300.

2.3 Selecting the Equipment Location

Transducer Mounting Location

It is very important that you mount the transducer correctly. The transducer provides the most reliable readings if it looks into water that is smooth and undisturbed.

Acoustic noise is always present and these sound waves can interfere with the operation of the transducer. Ambient (background) noise from sources such as waves, fish, rain and other vessels cannot be controlled. Carefully selecting the transducer’s mounting location can minimize noise generated by the vessel’s propeller(s), shaft(s), machinery, and other echo sounders. The lower the noise level, the higher the echo sounder gain that can be used, and the better the sounder’s performance.

Page 30

30 DSM300 Installation Manual

To ensure accurate readings, DO NOT mount the transducer in an area of turbulence or bubbles:

• near water intake or discharge openings

• behind strakes, fittings or hull irregularities

• behind eroding paint (an indication of turbulence)

Choose a location where:

• The water flowing across the hull is smoothest with a minimum of turbulence and bubbles (especially at high speeds).

• The transducer will be continuously covered by water when the boat is moving. If the transducer is mounted near the side of the boat, it may be exposed when the boat is turning.

• The transducer beam is unobstructed by the keel or propeller shaft.

• There is a minimum deadrise angle.

• There is adequate headroom inside the vessel for the height of the thru-hull

housing, tightening the nuts, and removing the valve assembly insert.

Transom Mount Transducer

• Single drive boat – Refer to Figure 2-3 . If your boat has one propeller (out- board or inboard), mount the transducer about 18" (455 mm) to the side of the boat’s centerline. To reduce any interference caused by air bubbles, choose the side on the downstroke of the propeller (usually the starboard side).

• Twin drive boat – If your boat has twin propellers (outboard or inboard-out- board), mount the transducer between the drives near the centerline of the boat. If the boat will be operated at high speeds, the transducer may be mounted closer to the centerline of the hull.

• If the propeller can be turned to steer the boat, allow at least 2" (50 mm) beyond the swing radius of the propeller. This will prevent the propeller from damaging the transducer when it is turned.

Page 31

Chapter 2: Transducer Installation 31

Approximately 18 in (457 mm) clearance

Be sure to allow at least 2 in (50 mm) beyond the swing radius of the propeller

D4871-2

Figure 2-3: Transom Mount Transducer Location

• Do not mount the transducer behind any hull fittings, intakes or other parts extending from the hull that may cause turbulence or air bubbles.

• The bracket has a quick-release mechanism, shown Figure 2-4 . This allows the transducer to flip up if it hits any debris or the bottom. Allow enough clearance above the transducer for it to swing upwards completely – this is about 10" (254 mm), measured from the bottom of the transom.

Allow a clearance of at least 254 mm (10 in)

• On a boat with a fiberglass hull, the leading edge of the transducer should extend 1/8" (3.2 mm) to 1/4" (6 mm) below the bottom edge of the hull as shown in Figure 2-5 . On an aluminum hull, the transduce r should extend a bit more – 1/4" (6 mm) to 3/8" (9 mm)

• If the boat will be trailered, be sure the transducer will not hit any rollers, bunks or fittings on the trailer.

• Displacement hull powerboat – Locate at 1/3 aft load waterline length (LWL) and 6 - 12" (150-300 mm) off the centerline on the side of the hull where the propeller is moving downward.

• Planing hull powerboat – Mount well aft, on or near the centerline, and well inboard of the first set of lifting strakes to ensure that it is in contact with the water at high speeds. Mount on the side of the hull where the propeller is moving downward.

Chapter 2: Transducer Installation 33

Outboard and I/O – Mount just forward of the engine(s). Inboard – mount well forward of the propeller(s) and shaft(s). Step-hull – Mount just ahead of the first step. Boats capable of speeds above 25 kn (29 m.p.h.) – Review transducer location and operating results of similar boats before proceeding.

• Fin keel sailboats – Mount to the side of the centerline and forward of the fin keel 1 - 2 ft (300-600 mm).

• Full keel sailboats – Locate amidships and away from the keel at the point of minimum deadrise angle.

• Fiberglass Hulls – Since the hull absorbs acoustic energy, transmitting through the hull reduces the sensor’s performance. Fiberglass hulls are often reinforced in places for added strength. These cored areas contain balsa wood or structural foam, which are poor sound conductors. If you cannot avoid locating the sensor over coring, follow the instructions for “Installation in a Cored Fiberglass Hull” on page 55.

• Thru-hull Transducer Headroom– Allow adequate headroom inside the vessel for the height of the thru-hull housing, tightening the nuts and removing the insert. The minimum headrooms are: With fairing: 10" (254 mm) Without fairing: 12" (305 mm)

• In-hull Transducer – Find a location where the fiberglass is solid: There are no air bubbles trapped in the fiberglass resin. There is no coring, flotation material, or dead air space sandwiched between the inside skin and the outer skin of the hull.

2.4 Installing the Transom Mount Transducer

Preparation

Transducer Mounting Bracket

When installed, the lower surface of the transducer should tilt down toward the rear at a slight angle (2° to 5°). The mounting bracket includes a wedge; depending on the angle of the transom on your boat, you may need to install this wedge to get the correct transducer angle.

1. To attach the transducer to the bracket, insert the transducer mounting lugs into the slot in the bracket as shown in Figure 2-7 .

Correct Incorrect

Attach the two parts Bracket is installed

Lower the transducer and snap in the release clip

2. Looking at the rear of the boat, be sure the bracket is vertical (perpendicular to the water line) and hold the bracket (plus the wedge, if used) against the transom. Trace the position of the screw slots, then mark the screw positions as shown in Figure 2-8 . The outer two screws should be placed about 1/4" (6 mm) up from the bottom of each slot, the center screw should be placed about 1/4" (6 mm) down from the top. This will allow the bracket to be adjusted up or down. Remove the bracket.

Page 36

36 DSM300 Installation Manual

Correct alignment

Insert screws 1 and 3, 6.4 mm (1/4 in) from the bottom of the slots, and screw 2, 6.4 mm (1/4 in) from the top the slot to allow room for adjustment.

Incorrect alignment

If screws are inserted this way it won't be possible to make the height adjustment.

Installation

1. On a fiberglass hull, to minimize surface cracking of the gel coat: Before drilling the pilot holes, use a 1/4" (6 mm) drill bit to drill a shallow hole (chamfer) at each location about 1/16" (1.5 mm) deep. Drill pilot holes 3/4" (19 mm) deep using a 9/64" (3.6 mm) drill bit. To prevent drilling too deeply, wrap masking tape around the drill bit about 7/8" (22 mm) from the tip. Drill in only as far as the tape.

2. Apply a good quality marine sealant to the pilot holes to protect the hull from water penetration.

3. Attach the bracket to the hull using the panhead screws with flat washers. Do not completely tighten the screws yet.

4. Move the bracket up or down so the leading edge of the transducer has the clearance shown in Figure 2-5 .

5. Once the bracket is in the correct position tighten the screws.

Preparation

Fairing

Most vessels have a deadrise angle at the transducer’s mounting location. If the transducer is mounted directly to the hull, the sonar beam will be tilted off-vertical at the same angle as the deadrise. To offset this deadrise angle, you can install a transducer fairing. Different fairings are available to fit various transducers.

CAUTION: Using a Fairing If thru-hull transducers are not carefully installed and fitted to the shape of the hull, the vessel may take on water. To ensure proper alignment and a secure fit, these transducer models MUST be installed with a fairing. In addition to improving sounder performance at all speeds, the fairing allows better fitting to the hull and dramatically increases the sealing surface.

Fairings are also strongly recommended for use with other high performance transducers. See the table that follows.

The fairing is used to:

• Vertically orient the sound beam by mounting the transducer parallel to the

water surface

• Minimize aerated water flowing over the transducer’s face by mounting it in

deeper water

• Reduce drag by directing the water around the multisensor

Page 38

38 DSM300 Installation Manual

The fairing is made of high impact urethane with an integrated cutting guide. It can be shaped to accommodate a deadrise angle of up to 25° and a range of hull thicknesses as follows:

CAUTION: The arrow on the fairing always points forward towards the bow. Be sure to orient the fairing on the band saw so the angle cut matches the intended side of the hull.

3. Place the fairing on the table so the cutting guide rests against the fence. The arrow/blunt end will point toward you for installation on the port side and away from you for installation on the starboard side of the boat.

CAUTION: Always wear safety goggles and a dust mask when drilling.

4. Recheck steps 1 through 3, then cut the fairing.

5. Shape the fairing to the hull as precisely as possible with a rasp or power tool.

Antifouling Paint

Marine growth can accumulate rapidly on the transducer’s surface, reducing performance in weeks. Surfaces exposed to salt water must be coated with antifouling paint.

Use water-based antifouling paint only. Never use ketone-based paint since ketones can attack many plastics, possibly damaging the transducer.

Reapply paint every six months or at the beginning of each boating season.

It is easier to apply antifouling paint before installation, but allow sufficient drying time. As illustrated in Figure 2-12 , paint the following surfaces:

Exposed area of the housing, including the acoustic window Bore of the housing up to 1-1/4" (30 mm) Outside wall below lower O-ring Exposed end of the paddle wheel insert Paddle wheel cavity Paddle wheel Blanking plug below the lower O-ring and the exposed end

Drilling Holes

CAUTION: Always wear safety goggles and a dust mask when drilling.

1. Drill a 1/8" (3 mm) pilot hole perpendicular to the water line from inside the hull (see Figure 2-9 ). If there is a rib or strut near the mounting location, drill from the outside.

If the pilot hole is drilled in the wrong location, drill a second hole in a better location. Apply masking tape to the outside of the hull over the incorrect hole and fill it with epoxy.

Page 42

42 DSM300 Installation Manual

2. Cut a hole from outside the hull: Fiberglass or wood hull – Use a 2" (51 mm) hole saw. Aluminium or steel hull – Use a 2-1/8" (54 mm) hole saw to accommodate the isolation sleeve used to prevent contact between the stainless steel housing and the metal hull.

3. Sand and clean the area around the hole, inside and outside, to ensure that the sealant will adhere properly to the hull. If there is any petroleum residue inside the hull, remove it with either a mild household detergent or a weak solvent (alcohol) before sanding.

4. Remove one safety ring, the retaining pin, the cap nut, and the hull nut from the transducer (see Figure 2-13 ).

2. Stainless steel transducer in metal hull - Slide the appropriate size isolation sleeve over the cable and onto the stem of the transducer as far down as possible (see Figure 2-9 ).

Page 44

44 DSM300 Installation Manual

Be sure the top of the isolation sleeve will be below the top of the backing block to prevent the sleeving from interfering with tightening the hull nut.

CAUTION: To prevent electrolytic corrosion, never allow direct contact between a stainless steel transducer and a metal hull.

3. Apply a 1/16" (2mm) thick layer of marine sealant to the sides of the transducer that will contact the fairing, if used, and up the stem 1/4" (6mm) higher than the combined thickness of the fairing, hull, backing block, and hull nut. This will ensure there is marine sealant in the threads to seal the hull and hold the hull nut securely in place (see Figure 2-13 ).

Stainless steel transducer in metal hull - Apply the marine sealant to the outside of the sleeving instead of the stem itself.

4. If a fairing is used, thread the transducer cable through the fairing and seat the transducer firmly within the recess in the fairing.

5. Apply a 1/16" (2mm) thick layer of marine sealant to the surface of the fairing that will contact the hull, if used.

Attaching the Transducer

1. From outside the hull, thread the cable through the mounting hole.

2. Push the stem of the transducer (with the fairing in place) into the mounting hole using a twisting motion to squeeze out excess sealant.

3. From inside the hull, slide the backing block onto the transducer cable and stem, seating it firmly against the hull (Figure 2-15 ).

CAUTION: Be careful to avoid cross threading the cap nut.

4. Screw the hull nut in place and tighten it with slip-joint pliers. Stainless steel transducer in metal hull - Be sure the top of the isolation sleeve is below the top of the backing block to prevent the sleeving from interfering with tightening the hull nut.

5. Apply a 1/16" (2mm) thick layer of marine sealant to the anti- rotation bolt, 1/4" (6mm) higher than the combined thickness of the fairing, hull, backing block, washer, and nut. This will ensure that there is marine sealant on the threads to seal the hull and hold the nut securely in place (see Figure 2-14 ).

6. Push the bolt through the fairing, if used, and into the hull.

7. From inside the hull, slide the washer and nut onto the bolt. Screw the nut in place and tighten it with slip-joint pliers. Wood hull - Allow for the wood to swell.

8. If a fairing is used, apply marine sealant to the flat side of the triangular plug. Push the plug into the triangular recess in the fairing. The triangular plug fits one way only. Be sure the curved side of the plug is exposed, matching the curve on the outside of the fairing. Tap it into place with a mallet.

CAUTION: For smooth water flow over the transducer’s sensor, be sure that the external surface of the installed triangular plug is FLUSH with the external curved surface of the fairing.

9. Being sure the valve assembly is seated firmly in the housing, carefully screw the cap nut in place. Hand tighten it only;

do not over tighten

10. Remove any excess sealant on the outside of the hull to ensure smooth water flow over the transducer.

Page 46

46 DSM300 Installation Manual

11. After the sealant cures, inspect and lubricate the O-rings on the paddle wheel insert with silicone grease or petroleum jelly (see Figure 2-16 ).

12. Slide the paddle wheel insert into the valve assembly with the arrow on the top pointing forward until it is fully seated (the insert fits one way only). Take care not to rotate the outer housing and disturb the sealant.

13. Slide the center ring of the safety chain onto the cable. Slide the retaining pin in place and reattach the safety ring (Figure 2-15 ).

CAUTION: Always attach the safety wire to prevent the insert from backing out in the unlikely event that the cap nut fails or is screwed on incorrectly.

14. Wrap one end of the safety wire tightly around the stem of the housing and twist it together with the long end. Lead the wire straight up and through one eye in the cap nut, then through one of the safety rings. Loop the wire through the pull ring and twist it securely to itself.

15. Route the cable to the transducer, being careful not to tear the cable jacket when passing it through the bulkhead(s) and other parts of the boat.

16. Attach the connector nut to the cable per instructions in

Connections

17. Attach the assembled connector cable to the transducer.

18. Route the other end of the cable to the DSM, being careful not to tear the cable jacket when passing it through the bulkhead(s) and other parts of the boat. To reduce electrical interference, separate the transducer cable from other electrical wiring and the engine.

19. Coil any excess cable and secure it in place using tie-wraps to prevent damage.

Installation in a Cored Fiberglass Hull

The core (wood or foam) must be cut and sealed carefully. The core must be protected from water seepage and the hull must be reinforced to prevent it from crushing under the hull nut, allowing the housing to become loose.

CAUTION: Always wear safety goggles and a dust mask when drilling.

1. Drill a 1/8" (3 mm) pilot hole perpendicular to the waterline from inside the hull. If there is a rib or strut near the selected mounting location, drill from the outside (see Figure 2-16 ). If the hole is drilled in the wrong location, drill a second hole in a better location. Apply masking tape to the outside of the hull over the incorrect hole and fill it with epoxy.

2. Using a 2" (51 mm) hole saw, cut a hole from outside the hull through the outer skin only.

3. Using the 2 3/8" (60 mm) hole saw, cut through the inner skin and most of the core from inside the hull. The core material can be very soft. Apply only light pressure to the hole saw after cutting through the inner skin to avoid accidentally cutting the outer skin

Note:

The optimal interior hole diameter is affected by the hull’s thickness and deadrise

an gle . It mus t be large e nou gh i n diamet er t o allow the cor e to be c omp let ely sealed.

4. Remove the plug of core material so the inside of the outer skin and inner core of the hull is fully exposed. Clean and/or sand the inner skin, core, and the outer skin around the hole.

CAUTION: Completely seal the hull to prevent water seepage into the core.

5. Coat a hollow or solid cylinder of the correct diameter with wax and tape it in place. Fill the gap between the cylinder and hull with casting epoxy. After the epoxy has set, remove the cylinder (see Figure 2-17 ).

Check for Leaks

CAUTION: Never install a thru-hull transducer and leave the boat unchecked for several days.

1. When the boat is placed in the water, immediately check around the thru-hull transducer for leaks. Note that very small leaks may not be readily observed. Do not to leave the boat in the water for more than 3 hours before checking it again. If there is a small leak, there may be considerable bilge water accumulation after 24 hours (probably not enough to cause water damage). If a leak is observed, repeat

Testing the Selected Mounting Location

Establishing a Performance Baseline

The results of this test are used to determine the best in-hull location for a transducer.

1. Take the boat to the maximum depth for which your instrument is rated, or the maximum depth in which you will operate the sounder.

2. Connect the transducer to the DSM. Refer to on

boat with the active face submerged in the water (see Figure 2-18 ). Keep the active face of the transducer parallel to the surface of the water.

4. Observe the sounder’s performance and depth reading.

D5000-2

Figure 2-18: Establishing a Performance Baseline

Testing the Mounting Location

While the boat is moving around the same site (and depth of water), test the transducer at your selected mounting location inside the hull. Use one of the methods below:

1. This method is recommended if the sensor will be located near the stern and the boat has a minimum deadrise angle.

i. Clean away any large build-up of dirt and/or grease using detergent or a

weak solvent such as alcohol.

ii. Place the sensor against the hull and allow bilge water to cover the sur-

face where they touch (see Figure 2-19 A).

CAUTION: Always wear safety goggles and a dust mask.

2. This method can be used at all hull locations. i. If the hull surface is not smooth, grind it with a disc sander. ii. Partially fill a thin plastic bag with water, place the sensor inside the bag

and close it tightly with a twist-tie.

iii. Wet the surface of the hu ll and press the sensor face against it through the

bag (see Figure 2-19 B).

3. This is the least desirable testing method, as it may be difficult to remove all traces of the petroleum jelly before bonding the base to the hull.

i. If the hull surface is not smooth, grind it with a disc sander. ii. Coat the face of the sensor with petroleum jelly.

Page 52

52 DSM300 Installation Manual

iii. Press it against the hull with a twisting motion (see Figure 2-19 C).

ABC

D5001-2

Figure 2-19: Testing the Transducer at the Selected Location

Observe the sounder’s performance and compare it to the baseline. Look for a stable depth reading that is similar to the baseline, compare the thickness and intensity of the bottom trace.

If the performance is close to the baseline, this is a good mounting location. Remember, some energy is lost transmitting through the hull.

If the test reading differs markedly from the baseline, you need to find another location to install the transducer.

If there is no reading or it is erratic, the sensor may be positioned over coring which is absorbing the acoustic energy. Choose another location. If no other spot is available, check with the boat manufacturer to be certain coring is present before proceeding with

Installation in a Cored Fiberglass Hull

Installation

1. Measure the deadrise angle of the hull at the selected location using a level and protractor (see Figure 2-20 ). Measure carefully, since the installed transducer must be within 5 ° of vertical.

CAUTION: Always wear safety goggles and a dust mask.

2. The hull surface to be bonded must be smooth and free of paint or any other finish. If the surface is rough, use a disc sander to smooth an area 4" (100 mm) in diameter.

3 . R e m ov e a ny d u st , g re a s e o r o il w i th a w ea k s ol v e nt , s uc h a s a l c oh o l, t o en s u r e

a good bond. Clean and dry both the selected area and the underside of the base.

5. The numbers on the flange of the base represent deadrise angles. Identify the number that most closely corresponds to the deadrise angle of your hull. Find its match on the opposite side of the flange. Keeping the keel direction arrows on the side of the base nearest the keel, align the two raised marks indicating your deadrise angle with the guideline drawn on the hull (see Figure 2-21 ).

CAUTION: The base must be liquid-tight.

6. When you are satisfied that the location of the transducer is optimal and the orientation of the base corresponds to the deadrise angle of your boat, apply a bead of adhesive to the bottom of the base flange. (Follow the adhesive manufacturer’s instructions for use). Press the flange firmly in place to form a liquid-tight seal and allow the adhesive to cure.

Transducer Cable

13. Attach the assembled connector cable to the transducer.

14. Route the other end of the cable to the DSM, being careful not to tear the cable jacket when passing it through the bulkhead(s) and other parts of the boat. To reduce electrical interference, separate the transducer cable from other electrical wiring and the engine.

15. Coil any excess cable and secure it in place using tie-wraps to prevent damage.

Note:

If you are using an extension cable, be sure to locate the mated 3-pin connectors well above the bilge waterline. To facilitate this, use cable clamps on either side of the connection.

Installation in a Cored Fiberglass Hull

Installation in a cored hull is difficult. The objective is to bond the sensor to the inside surface of the hull’s outer skin while preventing any moisture from penetrating the core.

Page 56

56 DSM300 Installation Manual

CAUTION: There is no way to determine if the outer skin is solid (no trapped air bubbles in the fiberglass) at the selected location before cutting the inner skin.

WARNING: Always wear safety goggles and a dust mask.

1. Using a 4" (100 mm) hole saw, cut through the inner skin and the core at the selected location (see Figure 2-24 ). The core material can be very soft. Apply only light pressure to the hole saw after cutting through the inner skin to avoid accidentally cutting the outer hull.

2. Remove the plug of core material, so the inner core of the hull is fully exposed. Sand the inside surface of the outer skin usi ng a miniature disc sander. Slightly undercut the surrounding coring if possible.

3. Clean and dry both the inside surface of the outer skin and the housing with a weak solvent, such as alcohol, to remove any dust, grease or oil.

CAUTION: Do not proceed if the hull temperature is below 60° F (15° C) since the cure time of the casting epoxy will be greatly extended.

4. If the hull temperature is above 60° F (15° C), mix a half cup of casting epoxy stirring carefully to avoid trapping air in the mixture. Pour this around the housing until the cavity is full. Allow the casting epoxy to set for at least 1 hour.

Chapter 3: Maintenance and Problem Solving 57

Chapter 3: Maintenance and Problem

Solving

This chapter provides information on routine maintenance and on possible causes of problems you may experience with your DSM300.

3.1 Maintenance

CAUTION: The sounder unit contains high voltage. Adjustments require specialized service procedures and tools only available to qualified service technicians. There are no user serviceable parts or adjustments and the operator should not attempt to service the equipment. The operator should not remove the rear cover of the module.

Routine Checks

The DSM300 is a sealed unit. Maintenance procedures are therefore limited to the following periodic checks:

• Examine the cables for signs of damage, such as chafing, cuts or nicks.

• Check that the cable connectors are firmly attached.

Cleaning Instructions

Cleaning the Module

The DSM300 is a sealed unit and does not require regular cleaning. However, if you find it necessary to clean the unit, please follow these basic procedures:

• Ensure power is off.

• Wipe the module clean with a damp cloth.

• If necessary, use IPA (isopropyl alcohol) or a mild detergent solution to

remove grease marks.

Cleaning the Transducer

Sea growth can collect quickly on the bottom of the transducer, this can reduce the performance in just a few weeks. To prevent the build-up of sea growth, coat the transducer with a thin layer of paint.

Page 58

58 DSM300 Installation Manual

Use only a water-based antifouling paint, or a water-based paint specifically designed for transducers. Apply the paint with a brush.

If your transducer becomes fouled or stops working because of sand or sea growth, use a stiff brush to clean it. You may sand the surface with a fine-grit wet or dry sandpaper (#320 grade or finer), but this will affect the performance of the unit when the boat is moving at higher speeds.

The paddle wheel mechanism may become jammed by dirt, grit or barnacles. Work the contaminant out of the mechanism, then clean the unit with soap and water or alcohol.

Cleaning the Hull

Use caution when sanding or cleaning the outside of the hull near the transducer.

CAUTION: Harsh cleaning solvents such as acetone may damage the transducer.

EMC Servicing and Safety Guidelines

• Raymarine equipment should be serviced only by authorized Raymarine service technicians. They will ensure that service procedures and replacement parts used will not affect performance. There are no user serviceable parts in any Raymarine product.

• Some products generate high voltages, so never handle the cables/connectors when power is being supplied to the equipment.

• When powered up, all electrical equipment produces electromagnetic fields. These can cause adjacent pieces of electrical equipment to interact with one another, with a consequent adverse effect on operation. To minimize these effects and enable you to get the best possible performance from your Raymarine equipment, guidelines are given in the installation instructions, to enable you to ensure minimum interaction between different items of equipment, i.e. ensure optimum Electromagnetic Compatibility (EMC).

• Always report any EMC-related problem to your nearest Raymarine dealer. We use such information to improve our quality standards.

• In some installations, it may not be possible to prevent the equipment from being affected by external influences. In general this will not damage the equipment but it can lead to spurious resetting action, or may result in momentary faulty operation.
