It works with NMEA 0183 compatible devices, such as chart plotters, radars or an on-board PC. In addition, it can be calibrated via a PC to match various sensors and installations.

The DST-2 can be used with new or existing transducer installations. When used with an existing transducer the DST-2 can provide a secondary depth sounder as a back up to a new sonar system.

FEATURES

Range of transducer frequencies available
Flash upgradable ‘future proof’ design
Generates the echo sounders ‘ping’ and analyses the returned signal
Digitises analogue signals into NMEA 0183 data

BENEFITS

Use with most NMEA 0183 displays
Can be calibrated
Trip data available with speed transducers
Designed to replace outdated stand-alone echo sounders
General survey firmware available.

NMEA / RS485 Output system
• Exceeds all NMEA 0183 output voltage
specifications
• Capable of driving up to 8 NMEA 0183
compliant devices
• Short circuit protected
• Static discharge protected
• Standard 4800 NMEA Baud rate. Other
Baud rates up to 38400 are possible for
customised software designs
RS485 Input System
• Exceeds all NMEA 0183 input voltage
specifications
• Standard RS485 input voltage
specifications
Data Output rate
• Depth, Speed, Trip and Temperature
data output once per second once the
respective transducer has been detected
• Customised output rates are available
Processing specifications
• Depth: Minimum and maximum
dependent on transducer.
Narrow beam transducers, like the
Airmar P66 transom-mount:
0 –10 knots: Minimum 0.3m,
Maximum 200m
10 – 40 knots: Minimum 0.5m,
Maximum 100m
Wide beam transducers, like the Airmar
DT800 through-hull:
0 –10 knots: Minimum 0.5m,
Maximum 150m
10 – 40 knots: Minimum 0.5m,
Maximum 100m
• Speed: Minimum and maximum
dependent on transducer. Airmar
standard paddle-wheel log transducer
allows 0.5 – 50 knots
• Temperature: Minimum and maximum
dependent on transducer. Uses an
industry standard thermistor (10 KO
at 25°C).
