2.2 Housing Material
The DST110 is supplied with a plastic housing that is suitable for most installations. As an option, Maretron offers both a bronze and stainless steel housing material. Please follow these recommendations for determining the right material for your particular installation.
• Plastic housing recommended for fiberglass or metal hulls only. Never install a plastic housing in a wood hull since swelling of the wood may overstress the plastic causing a fracture.
• Bronze housing recommended for fiberglass or wood hulls. Never mount a bronze housing in an aluminum hull because electrolytic corrosion will occur.
• Stainless steel housing compatible with all hull materials. Stainless steel is recommended for metal hulls to prevent electrolytic corrosion. A stainless steel housing must be isolated from a metal hull.
• Never install a metal housing in a vessel with a positive ground system.
2.3 Tools and Materials
• Water-based antifouling paint (mandatory in salt water)
• Safety
• Dust
• Electric drill with 10 mm (3/8”) or larger chuck capacity
• Drill bit:
3 mm or 1/8”
• Hole saw:
51 mm or 2” (plastic or bronze housing)
57 mm or 2-1/4” (stainless steel housing in a metal hull)
• Countersink tool (for installing a flush housing)
• Sandpaper

2.4 Pretest
Connect the DST110 to the NMEA 2000
®
network 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 instrument to the place of purchase.
2.5 Antifouling Paint
Marine growth can accumulate rapidly on the transducer’s surface reducing performance within 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 sensor.
It is easier to apply antifouling paint before installation, but allow sufficient drying time. Reapply paint every 6 months or at the beginning of each boating season. Paint the following surfaces
• Outside wall of the insert below the lower O-ring
• Exposed end of the insert cavity
• Paddlewheel
• Exterior lip of the housing
• Bore of the housing up 30 mm (1-1/4”)
• Blanking plug below the lower O-ring including the exposed end
Figure 1
– Antifouling Paint Application
2.6 Choosing a Mounting Location
The selection of a suitable mounting location is important for the optimal performance of the
Maretron DST110. The mounting location and orientation of the DST110 should be:
1. Preferably on the starboard side of the hull —where propeller blades are moving downward through the water.
2. Continuously Immersed In Water
3. Where Water Flowing across the Hull is Smooth with a Minimum of Bubbles and Turbulence
–
especially at high speeds.
4. Where the Transducer Beam is Unobstructed by the Keel or Propeller Shaft(s)
Revision 1.0 Page 3
DST110 User’s Manual
5. Where there is a Minimum Deadrise Angle
6. Accessible from Inside the Vessel – with adequate headroom for the height of the housing, tightening the nuts, and removing the insert. Allow a minimum of 280 mm (11”).
Please follow the following guidelines for different hull types (see Figure 2):
1. Displacement Hull Powerboats – Locate amidships near the centerline.
2. Planing Hull Powerboats – Mount well aft, on or near the centerline, and well inboard
of the first set of lifting strakes
to ensure that the DST110 is in contact with the water at high speeds.
3. Outboard and I/O – Mount just forward of the engine(s).
4. Inboard – Mount well ahead of the propeller(s) and shaft(s).
5. Step-hull – Mount just ahead of the first step.
6. Boat capable of speeds above 25 knots (29 MPH) – Review the installation location and operating results of similar boats before proceeding.
7. Fin Keel Sailboats – Mount on or as close as possible to the centerline and forward of the fin keel 300 to 600 mm (1 to 2’).
8. Full Keel Sailboats – Locate amidships and away from the keel at the point of minimum deadrise.
Caution:
Do not mount the DST110 in an area of turbulence or bubbles: near water intake or discharge openings; behind strakes, fittings, or hull irregularities.

2.7 Mounting the DST110
The Maretron DST110 is mounted through the hull. If the hull is a cored fiberglass hull, please
follow the instructions in Section 2.7.2. For other hull types, please follow the instructions in
2.7.1 All Hull Types Except Cored Fiberglass
2.7.1.1 Hole Drilling
Warning:
Always wear safety goggles and a dust mask.
1. Drill a 3 mm or 1/8” pilot hole from inside the hull. If there is a rib, strut, or other hull irregularity near the selected mounting location, drill from the outside.
2. Using the appropriate size hole saw, cut a hole from outside the hull.
Flush housing
– Use a countersink tool to make a “seat” in the 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 inside the hull, remove it with
Revision 1.0 Page 5
DST110 User’s Manual
either mile household detergent or a weak solvent (alcohol) before sanding.
Metal hull
– Remove all burrs with a file and sandpaper.
2.7.1.2 Bedding
Apply a 2 mm (1/16”) thick layer of marine sealant around the lip of the housing that contacts the hull and up the sidewall of the housing. The sealant must extend 6 mm (1/4”) higher than
the combined thickness of the hull, washer(s), and hull nut (see Figure 3). This will ensure
there is sealant in the threads to seal the hull and hold the hull nut securely in place.
Stainless steel housing in a metal hull
– To prevent electrolytic corrosion, the stainless steel housing must be isolated from the metal hull. Slide the isolation bushing onto the housing.
Apply additional sealant to the surfaces of the bushing that will contact the hull. plastic housing bronze housing stainless steel housing in metal hull insert cap nut
(plastic) housing safety wire hull nut washer hull insert cap nut

(housing and isolation bushing)
Figure 3 – Bedding and Installation
2.7.1.3 Installation
Caution:
Never pull, carry, or hold the DST110 by the cable as this may damage internal connections.
1. From outside the hull, push the housing into the mounting hole using a twisting motion
to squeeze out excess sealant (see Figure 3). Align the arrow on the lip of housing to
point forward toward the bow.
If the DST110 is not installed on the centerline, angle the housing slightly toward the centerline to align it with the water flow.
2. From inside the hull, slide the washer onto the housing.
Aluminum hull less than 6 mm (1/4”) thick
– Use an additional rubbery, fiberglass, or plastic washer. Never use bronze since electrolytic corrosion will occur. Never use wood since it will swell, possible fracturing the plastic housing.
3. Screw the hull nut in place.
Wood hull
– Allow the wood to swell before tightening the hull nut securely.
Plastic housing
– Do not clamp tightly on the wrenching flats, possibly causing the
Page 6 Revision 1.0
housing to fracture.
Plastic hull nut – Hand-tighten
only. Do not over tighten.
Metal hull nut
-- Tighten with slip-joint pliers.
4.
Remove any excess sealant on the outside of the hull to ensure smooth water flow over the DST110.
Warning: The O-rings must be intact and well lubricated to make a watertight seal.
5. After the sealant cures, inspect the O-rings on the insert (replace if necessary) and lubricate them with the silicone lubricant supplied.
6. Slide the insert into the housing with the arrow on the top pointing forward toward the bow. Screw the cap nut several turns until there is resistance. The arrow on the top of the insert, the cable exit, and the arrow on the lip will all be aligned. Continue to tighten the cap nut. Be careful not to rotate the housing and disturb the sealant. Hand tighten only. Do not over tighten.
Warning: 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.
7.
Attach the safety wire.
Plastic housing
– Attach the safety wire to one eye in the hull nut. Load the wire in a counterclockwise direction and thread it through one eye in the cap nut. Thread the wire through the eye a second time. Then, lead the wire through the eye in the insert.
Twist the wire securely to itself.
Metal housing
—Wrap one end of the safety wire tightly around the housing and twist it together with the long end. Lead the wire straight up and through one eye in the cap nut. Thread the wire through the eye a second time. Then lead the wire counterclockwise and through the eye in the insert. Twist the wire securely to itself.
This is an important safety step, since attaching the safety wire to a metal housing is different than attaching it to a plastic housing.
8. Route the cable to the network being careful not to tear the cable jacket when passing it through the bulkhead(s) and other parts of the boat. Coil any excess cable and secure it in place with zip-ties to prevent damage.
2.7.1.4 Checking for Leaks
Warning:
Never install a thru-hull transducer and leave the boat in the water unchecked for
several days.
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. It is best 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. If a leak is observed, repeat
“Bedding” and “Installing” immediately (see Sections 2.7.1.2 and 2.7.1.3).
Revision 1.0 Page 7
DST110 User’s Manual
2.7.2 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 not allowing the housing to become loose.
Warning: always wear safety goggles and a dust mask.
1. Drill a 3 mm or 1/8” pilot hole from inside the hull. If there is a rib, strut, or other hull irregularity near the selected mounting location, drill from the outside. (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 51 mm or 2” hole saw, cut the hole from outside the hull through the outer skin
3. From inside the hull, use a 60 mm or 2-3/8” hole saw to cut through the inner skin and most of the core. 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.
4. Remove the plug of core material so the inside of the outer skin and the inner core of the hull are fully exposed. Sand and clean the inner skin, core, and the outer skin around the hole.
Caution: Completely seal the hull to prevent water seepage into the core.
5. If you are skilled with fiberglass, saturate a layer of fiberglass cloth with a suitable resin and lay it inside the hole to seal and strengthen the core. Add layers until the hole is the correct diameter.
Alternatively, a hollow or solid cylinder of the correct diameter can be coated with wax and taped in place. Fill the gap between the cylinder and hull with casting epoxy. After the epoxy has set, remove the cylinder.
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 “Bedding” and “Installing” (see Sections 2.7.1.2 and 2.7.1.3).

2.8 Connecting the DST110
The Maretron DST110 provides a connection to an NMEA 2000
®
interface through a five pin
male connector located on the end of the cable attached to the DST110 (see Figure 5). You
connect the DST110 to an NMEA 2000
®
network by plugging the male connector into a female receptacle of the NMEA 2000
®
network (note the key on the male connector and keyway on the female connector). Be sure the cable is connected securely and that the collar on the cable connector is tightened firmly. The DST110 is designed such that you can plug or unplug it from an NMEA 2000
®
network while the power to the network is connected or disconnected. Please follow recommended practices for installing NMEA 2000
®
network products.

DST110 User’s Manual
2.8.1 Checking Connections
Once the NMEA 2000
®
connection to the Maretron DST110 have been completed, check to see that speed, depth, and temperature information is being properly transmitted by observing
an appropriate display. Refer to Section 8, “Troubleshooting”, if no heading information
appears, otherwise proceed to Section 3 entitled “Calibration”.
3 Transducer Depth Offset Calibration
The DST110 measures the depth of the water from the transducer, which may or may not be the waterline depth or the depth of water underneath the keel depending on the mounting location. Fortunately, the DST110 can be calibrated for reporting the offset from the transducer to the waterline or the DST110 can be calibrated to report the offset between the transducer and the lowest point on the vessel. Depth display readings then report either the waterline depth or the depth under keel depending on your preference.
The easiest way to set the offset calibration is through a Maretron display product (please refer to your Maretron display manual) although users with direct access to the NMEA 2000
® interface can perform transducer offset calibration directly through the NMEA 2000
®
interface
(see Appendix A).
4 Temperature Offset Calibration
The Maretron DST110 may be programmed with an offset value which is added to the water temperature measured by the DST110 before the value is transmitted over the NMEA 2000
® network.
The temperature offset in the DST110 may be programmed by a Maretron display product
(please refer to your Maretron display manual).
5 Speed Multiplier Calibration
While the Maretron DST110 as shipped from the factory accurately represents the speed of water traveling past the paddlewheel sensor, the speed of water past the sensor might not be the same as the speed of the vessel, due to hull shape or how or where the DST110 is mounted. The DST110 can be programmed with a multiplier by which the internally calculated speed through water is multiplied before the speed through water value is transmitted over the
NMEA 2000
®
network. In this way, the DST110 can be programmed such that its transmitted speed through water can more closely match the speed of the vessel.
The speed multiplier in the DST110 may be programmed by a Maretron display product
(please refer to your Maretron display manual).
6 Zeroing the Cumulative Voyage Distance (Log)
The Maretron DST110 automatically logs two different cumulative distances; 1) total cumulative distance since installation, and 2) cumulative voyage distance since reset. You cannot zero out the total cumulative distance since installation but you are able to zero out the cumulative voyage distance since reset. Zeroing the cumulative voyage distance is easily done

7 Maintenance
7.1 Using the Blanking Plug
To protect the paddlewheel, use the blanking plug when the boat will be kept in salt water for more that a week, or when the boat is removed from the water, or aquatic growth build-up on the paddlewheel is suspected due to inaccurate readings from the instrument.
Warning: The O-rings must be intact and well lubricated to make a watertight seal.
1. Inspect the O-rings on the blanking plug (replace if necessary) and lubricate them with the silicone lubricant supplied or petroleum jelly (Vaseline
®
2. Remove the insert from the housing by removing the safety wire. Loosen the cap nut.
3. With the blanking plug ready in one and, pull the insert most of the way out. Remove the insert and rapidly replace it with the blanking plug. With practice, only 250 ml (10 oz.) of water will enter the boat.
4.
Screw the cap nut several turns until there is resistance. Continue to tighten the cap nut.
Hand-tighten
only. Do not over tighten.
Warning: 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.
5. Reattach the safety wire.
6. Winterizing
After the boat has been hauled for winter storage, remove the blanking plug/insert to let the water drain away before re-inserting it. This will prevent any water from freezing around the blanking plug/insert and possibly cracking it. insert blanking plug arrow

7.2 Servicing the Insert
Aquatic growth can accumulate rapi dly on the depth transducer’s surface and impede or freeze the paddlewheel’s rotation, reducing performance within weeks. Clean the insert with a soft cloth and mild household detergent. If the fouling is severe, remove the paddlewheel with needle-nose pliers. Use a stiff brush or putty knife to remove the growth taking care to avoid scratching the depth transducer. Lightly wet sand with fine grade wet/dry paper.
T he water lubricated paddlewheel bearings have a life of up to 5 years on low-speed boats
[less than 10 knots (11 MPH)] and 1 year on high-speed vessels. Paddlewheels can fracture and shafts can bend due to impact with water borne objects and mishandling in boat yards. Orings must be free of abrasions and cuts to ensure a watertight seal. A replacement
Paddlewheel Kit (33-398-04) is available.
1. Remove the old paddlewheel shaft with needle-nose pliers (see Figure 6).
2. Place the new paddlewheel in the cavity with the flat side of the blade facin g the same direction as the arrow on the top of the insert.
3. Tap the new shaft into place until the end is flu sh with the outside wall of the insert.
4. Install a large O-ring near the top of the insert. Install a small O-ring near the
5. paddlewheel.
Place the rema ining two O-rings in similar positions on the blanking plug.
7 .3 Replacement Parts
Lost, broken, and worn parts shoul d be replaced immediately. If you have purchased a plastic housing and have a wood hull or desire greater strength, purchase a Maretron metal housing.

Periodic Data Transmitted PGNs
PGN 128267 – Water Depth
The DST110 uses this PGN to indicate the water depth relative to the transducer and offset of the measuring transducer.
Field 1: SID – The sequence identifier field is used to tie related PGNs together. For example, the DST110 will transmit identical SIDs for Speed (PGN 128259) and Water depth
(128267) to indicate that the readings are linked together (i.e., the data from each
PGN was taken at the same time although reported at slightly different times).
2: Water Depth, Transducer – This field is used to report the depth relative to the transducer in units of 1x10
-2
m.
3: Offset – If the value of this field is positive, it represents the difference in depth between the transducer and the waterline of the vessel. If the value of this field is negative, it represents the difference in depth between the transducer and the keel of the vessel. The unit of measurement for this field is 1x10
-3
m.
4: Reserved – This field is reserved by NMEA; therefore, the DST110 sets all bits to a logic 1.
PGN 128259 – Speed
The DST110 uses this PGN to indicate the vessel’s speed through the water.
Field 1: SID – The sequence identifier field is used to tie related PGNs together. For example, a compass would transmit identical SIDs for Water depth (128267) and Speed (PGN
128259) to indicate that the readings are linked together (i.e., the data from each
PGN was taken at the same time although reported at slightly different times).
2: Speed, Water Referenced – This field is used to report the vessel’s speed relative to the water in units of 1x10
-2
meters per second.
3: Speed, Ground Referenced – This field is not used by the DST110; therefore, it transmits a value of 0xFFFF (65,535) for this field (which represents “data not available”).
4: Reserved – This field is reserved by NMEA; therefore, the DST110 sets all bits to a logic 1.
PGN 130310 – Environmental Parameters
The DST110 uses this PGN to indicate the water temperature.
Field 1: SID – The sequence identifier field is used to tie related PGNs together. For example, the DST110 will transmit identical SIDs for 130310 (Environmental Parameters) and
130312 (Temperature) to indicate that the readings are linked together (i.e., the data from each PGN was taken at the same time although they are reported at slightly different times).
2: Water Temperature – This field indicates the water temperature in units of 1x10
-2
°K.
3: Outside Ambient Air Temp – This field is not used by the DST110; therefore, it transmits a value of 0xFFFF (65,535) for this field (which represents “data not available”).

4: Atmospheric Pressure – This field is not used by the DST110; therefore, it transmits a value of 0xFFFF (65,535) for this field (which represents “data not available”).
5: Reserved – This field is reserved by NMEA; therefore, the DST110 sets all bits to a logic 1.
PGN 130311 – Environmental Parameters
The DST110 uses this PGN to provide a regular transmission of water temperature. The factory default state of this PGN is disabled. The transmission of this PGN can be enabled
(see PGN 126208 – NMEA Request Group Function – Transmission Periodic Rate).
Field 1: SID – The sequence identifier field is used to tie related PGNs together. For example, the DST110 will transmit identical SIDs for 130310 (Environmental
Parameters) and 130312 (Temperature) to indicate that the readings are linked together (i.e., the data from each PGN was taken at the same time although they are reported at slightly different times).
2: Temperature Instance – The DST110 sets this field to a value of 0x00 to indicate that the temperature reading is a reading of sea temperature.
3: Humidity Instance – This field is not used by the DST110; therfore, it transmits a value of 0x03 (3) for this field (which represents “data not available”),
4: Temperature – This field is used to indicate the water temperature in units of 0.01°K.
5: Humidity – This field is not used by the DST110; therefore, it transmits a value of
0x7FFF (32767) for this field (which represents “data not available”).
6: Atmospheric Pressure – This field is not used by the DST110; therefore, it transmits a value of 0xFFFF (65535) for this field (which represents “data not available”).
PGN 130312 –Temperature
The DST110 uses this PGN to provide a regular transmission of water temperature. The factory default state for this PGN is disabled. The transmission of this PGN can be enabled
(see PGN 126208 – NMEA Request Group Function – Transmission Periodic Rate).
Field 1: SID – The sequence identifier field is used to tie related PGNs together. For example, the DST110 will transmit identical SIDs for 130312 (Temperature) and
130311 (Environmental Parameters) to indicate that the readings are linked together
(i.e., the data from each PGN was taken at the same time although they are reported at slightly different times).
2: Temperature Instance – The DST110 sets this field to identify a particular temperature measurement from the source specified in Field 3. Every temperature measurement from a given source type on the network should have a distinct instance value, so that monitoring devices and displays can identify which measurement is which.
3: Temperature Source – This field is used to indicate the type of temperature measurement being taken. The DST110 transmits a value of 0x00 (0) for this field, which represents “Sea Temperature”.
4: Actual Temperature – This field is used to indicate the temperature, whose source is specified in field 2, in units of 0.01°C.
5: Set Temperature – The DST110 sets this field to a value indicating “data not available”.
6: Reserved bits – The DST110 sets all bits in this field to a value of “1”.

PGN 128275 – Distance Log
The DST110 uses this PGN to indicate the total cumulative distance traveled through the water since installation and the cumulative voyage distance traveled through the water since the last reset. The distances through water are accumulated and the values are periodically stored in memory.
Field 1: Measurement Date – This field is not used by the DST110; therefore, it transmits a value of 0xFFFF (65,535) for this field (which represents “data not available”).
2: Measurement Time – This field is not used by the DST110; therefore, it transmits a value of 0xFFFFFFFF (4,) for this field (which represents “data not available”).
3: Total Cumulative Distance – This field indicates the total distance traveled through the water since the DST110 was installed in units of 1 m.
4: Distance Since Last Reset – This field indicates the total distance traveled through the water since this parameter was last reset. This is most commonly reset at the beginning of a voyage and then reflects the total distance traveled in that voyage.
The unit of measurement for this field is 1 m.
