DST-2: Overview

The Actisense DST-2 module is the market-leading way to take analogue transducers into the digital age.

When used with new or existing transducers fitted to a vessel, the DST-2 digitises depth, speed and temperature transducer signals into NMEA data to deliver best-in-class seabed tracking.

When used with an existing installed transducer, the frequency of the DST-2 must match that of the transducer. Typical frequencies used by manufacturers are 150 kHz (common in the UK and EU) and 170 kHz & 200 kHz (more common in the USA).

The module is ideal for operation with any NMEA 0183 compatible devices, such as chart plotters, radars or an on-board PC. In addition, it can be calibrated via a PC for various sensors and installations.

A special 235 kHz version of the DST-2 is available. Please contact Actisense sales for MOQ and pricing information.

Powerful Digital Signal Processor

A high-speed microcontroller capable of 10 million instructions per second, and a large memory to handle the advanced digital signal processing techniques required to calculate the depth of water below the vesel, vessel speed, distance travelled and water temperature.

Class Leading Depth Performance

Depth performance in a class of its own, with an industry leading shallow depth capability of just 0.3 metres / 1 foot (below 10 knots), and a maximum depth of 200 metres (depending on the transducer type).

Proven Depth Algorithm

The depth processing algorithms have been fine-tuned over an 6 year period and represent the best-in-class available for calculating the correct depth, even under difficult conditions - at speed, with layers of algae, turbulence and interference from other vessels.

Optional Depth Frequencies

Three variations of the module are available to match an existing depth tranducer's frequency - 
150kHz, 170kHz or 200kHz.

A special 235kHz version is also available. Please contact sales for MOQ and pricing information.

Speed Tracking Algorithm

Speed calculations can accurately track even the smallest changes in vessel speed, with a resolution of 0.1 knots.

Temperature Algorithm

A thermistor can precisely measure the water temperature around the transducer, with a 0.1°C resolution.

Transducer Interfaces

Depth: connects to a standard piezoelectric depth transducer crystal element using a three-wire interface. Speed: connects to a standard ' paddle-wheel' hall-effect speed transducer using a three-wire interface. Temperature: connects to a standard metal case thermistor transducer using a two-wire interface.

P66/IP68 Case and Grommet Design

A robust polycarbonate case with a high waterproof certification. The small case size is ideal for space restrictive applications.

High Quality Angled Screw Terminals

The 'moving cage' type terminals make cable installation a simple and quick operation.

NMEA 0183 Full-Differential Output Driver

Can drive up to 4 fully compliant NMEA 0183 device loads, with a 10mA (maximum) drive capability. The full-differential output ensures better quality communications and lower noise emissions on unshielded twisted pair cabling. Simply wire to a device capable of showing NMEA information to view all the NMEA data. sit the Active Research website to view general information on our current product partnerships.

NMEA 0183 Sentences Output

Depth (DBT and DPT), Speed (VHW), Distance Log (VLW) and Water Temperature (MTW) sentences are output once per second.  Speed and distance sentences are output upon receipt of at least three pulses from a compatible log transducer.  Likewise, temperature sentences are output when a compatible transducer is detected.

Wide Battery Input Voltage Range

For maximum compatibility, any battery supply between 11 and 28 volts can be used.

Very Low Current Consumption

Ideal for small vessels with small batteries.
