Page 5: General
Temperature Transducer. Maretron has designed and built your transducer to the highest standards for years of dependable and accurate service. The DST110 detects the water depth with a 235 KHz depth transducer, the water speed with a paddlewheel and Hall effect sensor, and the water temperature with a precision thermistor element. -
Page 6: Installation
If any of these items are missing or damaged, please contact Maretron. 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 housing material. Please follow these recommendations for determining the right material for your particular installation. -

Cylinder, wax, tape, and casting epoxy. 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. -
Page 8: Choosing A Mounting Location
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. -

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. -

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). -

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. -
Page 12: Figure 4 - Preparing A Cored Fiberglass Hull
DST110 User’s Manual 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.) -
Page 13: 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 6). You ® connect the DST110 to an NMEA 2000 network by plugging the male connector into a female ®... -

This value should be programmed in each DST110 so that each DST110 is associated with a unique device instance number. The default instance number is 0, which is used to indicate the first DST110 that is connected to the network. -

DST110 User’s Manual 4 Maintenance 4.1 Using the Blanking Plug To protect the paddlewheel, use the blanking plug when the boat will be kept in salt water for more than 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. -
Page 17: Replacement Parts
Lost, broken, and worn parts should be replaced immediately. If you have purchased a plastic housing and have a wood hull or desire greater strength, purchase a Maretron metal housing. Obtain the following parts from your marine dealer or directly from Maretron. -

Page 21: Maretron (2 Year) Limited Warranty
8 Maretron (2 Year) Limited Warranty Maretron warrants the DST110 to be free from defects in materials and workmanship for two (2) years from the date of original purchase. If within the applicable period any such products shall be proved to Maretron’s satisfaction to fail to meet the above limited warranty, such products shall be repaired or replaced at Maretron’s option. -

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... - Page 24 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.
- Page 25 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”).
- Page 26 This will set the offset for the water depth measurement. The user has a choice of two types of offset to program into the DST110’s depth transducer. Positive values of offset indicate the depth of the transducer below the waterline. Negative values of offset indicate the depth of the bottom of the boat’s keel below the DST110’s depth transducer.
