Why would I want or need an Active DST Module?

← Back

The Actisense Active DST Module was designed as the perfect solution to:

A) the situation where an existing depth sounder’s transducer is still working but the display unit controlling it is faulty and/or too old.

B) the situation where the user requires to use a non-Airmar transducer, but still wants all the benefits of the Active Transducer.

The Actisense Active DST Module, working with a large range of transducers, can supply high quality depth, speed, distance log and water temperature information (in NMEA 0183 format) to a chart plotter, radar or even an onboard PC.

The Active DST Module design is very flexible, having been tried and proven with a large range of transducers. This list is always growing, and currently includes, but is not limited to:

  • Airmar 170 kHz, 200kHz and 235kHz (In-hull, Thru-hull, Transom mount)
  • Skipper 200 kHz (In-hull)
  • EchoPilot Marine 150 kHz (In-hull)
  • NASA Marine 150 kHz (In-hull)

The proven Actisense depth sounding algorithm, working with, for example an Airmar transducer, can provide the best-in-class tracking of the seabed – capable of tracking the seabed down to 0.3 metres (1 foot) and up to 200 metres (660 feet), and still outperform other depth sounders at speeds up to 50 knots (57 MPH).

Added to this is the ability to interface to a standard paddle-wheel log transducer and calculate the vessel’s speed and the trip distance travelled (log).

The final ability of interfacing to a standard temperature transducer, to calculate the current water temperature, completes the picture of this powerful, all-in-one system.

Simply install the Actisense Active DST Module (and the associated transducers if not already fitted) and connect it to your NMEA 0183 network – normally through an NMEA Multiplexer (NDC-4) or an NMEA Buffer (NBF-2) – and all the NMEA data will be instantly available to any NMEA devices that require it.

Using the Actisense RS485 to RS232 Adapter cable and free software available (on this website when necessary), the NMEA Active DST Module software may be updated as many times as required with the very latest software enhancements, or even user defined software.
