Actisense DST 2 Depth Sounder Module

Breathe new smart digital life into your old or new
transducers, with digital signal processing technology.

The Actisense DST 2 Depth Sounder 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 and
200 kHz (more common in the USA).

The Actisense DST 2 Depth Sounder 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.

Actisense DST 2 Depth Sounder Module Features:

• 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
