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
tranducer's 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 Terminals
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 customer's
individual requirements - be they different Baud rates, faster/slower data
output rates, and/or specific data output formats, or even a different depth
frequency.
