DST-1 DST Module
This version of the DST is no longer in production. Please see the current DST-2 model.
The Actisense Active Depth, Speed & Temperature module is the best solution for interfacing standard analogue transducers and NMEA 0183 compatible chart plotters, radars, and on-board laptop PC’s.
Designed for use with most existing analogue transducers already fitted to a vessel, or new analogue transducers. Our industry proven depth sounder algorithm has the best-in-class seabed tracking, and when in conjunction with a good quality depth transducer, can track the seabed down to 0.3m or 1 foot (proven with Airmar transducers).

100W peak depth power enables a maximum depth range of 200m or 660 feet under optimum conditions (proven with Airmar transducers). 150 KHz & 200 KHz depth transducer frequencies are available to match most existing transducers. For enhanced interference rejection (from other sounders), a 235 KHz capable module is also available.

Log transducer and temperature thermistor interfaces allow additional data to be provided over the NMEA data stream, giving a cable saving. Easy reprogramming of the DST module’s software is possible, to include the very latest software enhancements or customisations.

The DST module’s data interface is configured for NMEA 0183, but can operate as a fully bi-directional RS485 interface for customised applications, such as an on-board multiple depth sounder network.

Testimonial
"We have been working with Actisense for more than 9 years now. Our sales in terms of units raise to a 4 digit figure. As far as I can remember, we have returned just one NMEA Buffer back to the manufacturer under warranty. That says it all."
