Preface

Purpose
Raymarine DSM300 Digital Sounder Modules provide echo sounder data that can be displayed on Raymarine E Series, C Series, and hsb2 PLUS (Pathfinder) Series 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 thoroughly. Raymarines 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. 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.

EMC Conformance

All Raymarine equipment and accessories are designed to the best industry standards for use in the recreational marine environment. The design and manufacture of Raymarine equipment and accessories conform to the appropriate Electromagnetic Compatibility (EMC) standards, but correct installation is required to ensure that performance is not compromised.

Conventions

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 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 chapter.) Magnetic compass: Mount the unit at least 3 ft (1 m) away from a magnetic 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 overheating. 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.
1.4 Mounting the Sounder Module
The DSM300 can be mounted either above or below deck using the supplied hardware. To allow for ease of cable connection, mount the sounder module so that the cables hang below the unit.

To mount the DSM300:

1. Hold the module in the location where you want to mount it, making sure it is perpendicular to the deck. 2. Mark the location of the four key holes onto the mounting surface.

D7479-1

3. Drill a 9/64" pilot hole at each of the marked locations.

D7538-1

Note: For fiberglass with a gelcoat surface, you should overdrill the surface to prevent the
gelcoat from chipping when driving in the screw. Before drilling the pilot hole, hand drill the marked location with an oversized bit and countersink to approximately 3/8" diameter. 4. Drive the supplied #8 screws into the pilot holes. Screw them in about half way. 5. Mount the module to the surface, slipping the screw heads through the four key holes.
6. Press the module downward so the screws align with the narrow end of the keyholes.

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 boats 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 hsb2 PLUS (Pathfinder) Series displays, or longer C Series cables, must be purchased separately. See Table 1-1 Cable Options on page 9 for a list of available display cables. Transducer cable, 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. 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 replacedit cannot be repaired. Cutting the transducer cable will void the warranty and invalidate the European CE mark.

1.6 System Connections

The connector panel provides the following connection sockets: T/D, 7-pin socket for connecting to the transducer HSB2, 4-pin socket for connecting to a C Series or hsb2 PLUS Series display POWER, 3-pin socket for connecting to boats DC power systems rated from 10.7 V to 32 V and one RF ground (screen) connection SEATALK HS, RJ-45 socket for connecting to an E Series display

Figure 1-4: DSM300 Connector Panel CAUTION: To protect exposed pins, please place the attached dust cover over the socket (4-pin or RJ-45) to which you are not connecting a cable. The following sections detail the connectors used when installing the DSM300.

DC Power Connection

The DSM300 is intended for use on boats 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 units connector panel. The connector (viewed from the outside) and pin functions are shown in the following diagram and table.

D6162-1

Figure 1-6: Power Connector

Pin No. 3 Function Color

Battery positive (12/24/32 V systems) Red Battery negative Shield (drain wire) Black 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 boats 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 boats 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.

Transducer Connection

A 30 ft (10m) cable is supplied with the transducer. For details see Transducer 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.

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 boats 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 nut on the rear panel of the module. If your boat does 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 boats ground. Floating, with neither battery terminal connected to the boats ground.
This system is not intended for use on positive ground vessels.

In-Hull Mounting Kit Transom Mounting Kit Notes:
(1) To ensure proper alignment and a secure fit, many thru-hull transducers
require a fairing for installation. In addition to improving sounder performance at all speeds, the fairing allows better fitting to the hull and dramatically increases the sealing surface. (2) This information was current as of the date this handbook was printed. New transducer models are constantly becoming available. Check with your dealer for the most current list.

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 Transducer Cable Connections. 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).
Before attaching the transducer cable, you will need to attach the connector nut and split ring. These items, plus a wedge tool, are included in the transducer packaging.
Connector/cable Protrusion Mounting groove
Nut Split Split ring Wedge tool

D5256-1

Figure 2-1: Assembling the Transducer Connector
To attach the transducer cable connector:
1. Slip the nut over the connector cable end. Push it past the connector and over the cable. 2. Insert the wedge tool into the groove in the split of the split ring and slide the wedge tool until its squared end is flush with the larger edge of the split ring. 3. Slip the split ring and wedge tool over the connector body until aligned with the mounting groove on the connector. 4. Remove the wedge tool and seat the split ring in the mounting groove, making sure the connector protrusion falls into the split. 5. Slip the nut forward until it stops. Twist until the protrusions on the inside of the nut align with the grooves on the split ring. 6. Slip the nut forward and snap into place.
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 connector. Attach the transducer cable connector directly to the sounder module. Combined speed/temperature transducers have a 3 pin female connector 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-cables 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 system requires both a Y-cable and a transducer extension 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. 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.

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

Figure 2-7: Fitting the Transducer to the Bracket 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.

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. 3

Incorrect alignment

If screws are inserted this way it won't be possible to make the height adjustment. 3

D4875-2

Figure 2-8: Position of Screws in Mounting Bracket

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.

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 transducers 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

Note: To install the thru-hull transducer in a cored fiberglass hull, follow the instructions in Installation in a Cored Fiberglass Hull on page 48.

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.
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 ).

Dry Fit for Fairing

CAUTION: If a fairing is used, the anti-rotation bolt must be installed to prevent the fairing from rotating when the boat is underway. 1. Dry fit the transducer to locate the hole for the anti-rotation bolt. 2. Thread the transducer cable through the large hole in the fairing and through the mounting hole in the hull. Seat the transducer firmly in the recess in the fairing. Note: The transducer must be flush with the fairing. If it is recessed more than 1/64" (0.5mm) inside the fairing, you may carefully file or sand the fairing flush with the transducer.
CAUTION: Always wear safety goggles and a dust mask. 3. Attach the drill bit to your drill appropriate for your fairing:

4. Slide the transducers stem with the fairing in place into the mounting hole. Be sure the triangular recess in the fairing is pointing forward toward the bow. 5. While holding the assembly in place and using the bolt hole in the fairing as your guide, drill a hole through the hull for the anti-rotation bolt. 6. Remove the assembly and cable from the mounting hole. 7. Sand and clean the area around the hole, inside and outside, to ensure that the sealant will adhere properly to the hull. Metal hull - Remove any burrs around both holes with a file and sandpaper.

Seating

1. Remove the transducer from the fairing, if used. 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 ).
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.

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 hulls thickness and deadrise angle. It must be large enough in diameter to allow the core to be completely 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 ).

Figure 2-17: Preparing a Cored Fiberglass Hull 6. 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 mild household detergent or a weak solvent (alcohol) before sanding. 7. Proceed with Seating on page 43 and Attaching the Transducer on page 44.

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 Seating on page 43 and Attaching the Transducer on page 44 immediately.

Figure 2-23: Installing the O-ring 9. When the adhesive on the base has cured, pour 2.4 fl. oz. (71 mil) of mineral oil into the base. 10. Lock the transducer assembly into the base by inserting the keys on the locking ring in the notches in the base. Press down and rotate clockwise until seated (see Figure 2-22 ). 11. 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. 12. Attach the connector nut to the cable per instructions in Transducer Cable Connections on page 26. 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 hull is difficult. The objective is to bond the sensor to the inside surface of the hulls outer skin while preventing any moisture from penetrating the core.
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 using 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.
