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.
Benefits of the DST-2:
- Digitises analogue signals into NMEA data
- Use with any NMEA 0183 compatible device
- Range of frequencies available
- Flash upgradeable future-proof design
- Can be calibrated
- Trip data available with speed transducers
- 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 tranducers frequency -
150kHz, 200kHz or 235kHz.
- 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 TerminalsL 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.
- 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.
- Customise Service Available: Actisense® offers a full user configuration service for the Active DST Module range. The module can be fine tuned to match each customers individual requirements - be they different Baud rates, faster/slower data output rates, and/or specific data output formats, or even a different depth frequency.
