Can the module be customised to fit my requirements exactly?

Actisense can offer full design support at competitive rates for companies and individuals wishing to include the Active DST Module as part of their sensor solution, or wishing to create their own depth sounder solutions.

Possible customised applications range from outputting the data in a customer's specific format (for example, to an onboard depth sounder network that could indicate the depth at all four corners of a vessel's hull), changing the rate of data transmissions (update rate), to simply using a different Baud rate.

Almost anything can be customised.

If you or your company is interested in this full Active transducer custom design service, please contact Actisense.

Why would I want or need an Active DST Module?

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.

What special features does it have?

This is a very open-ended answer because, as the Actisense Active DST Module's software can be updated, the list of special features can be extended or modified when required - by Actisense, or a particular customer.

The first special feature developed for a commercial customer was the Hydrographic firmware upgrade which enables additional proprietary NMEA 0183 data to be sent to the PC allowing a hydrographic (picture) slice of the water/seabed to be displayed in full colour, detailing the differing strengths of all echoes.

By scrolling this data every time another slice is received, a history of seabed information is built up. This display creates a detailed picture of the seabed and other echoes (potentially fish) found in the water below the transducer.

This specialist firmware and NMEA display software (for a Windows PC or laptop) is not currently available to the general public.

Please contact Actisense if this option is of interest to you or your company.
