Actisense DST-2 Active Depth, Speed, and Temperature Module

The Actisense DST-2 is an active transducer interface module designed to digitize analogue signals from depth, speed, and temperature sensors into standard NMEA 0183 data. By converting raw transducer readings into digital sentences, the Actisense DST-2 allows older analogue transducers to interface seamlessly with modern chartplotters, radars, instrument displays, and onboard PCs without replacing existing hull fittings.

Connecting an existing analogue transducer to the Actisense DST-2 provides a cost-effective alternative to hauling out a vessel to install expensive smart transducers. For NMEA 2000 networks, pairing this module with an Actisense NGX-1 gateway bridges converted 0183 sentences directly to NMEA 2000 backbones, saving time and maintenance costs during electronics retrofits.

Key Features of the Actisense DST-2

• Analogue-to-Digital Signal Conversion: Converts analogue depth, paddlewheel speed, and thermistor temperature signals into NMEA 0183 sentences

• Universal NMEA 0183 Compatibility: Fully compatible with NMEA 0183, RS232, and RS422 displays, supporting configurable baud rates from 4,800 to 38,400 baud

• Multiple Transducer Frequencies: Supports standard transducer drive frequencies including 150kHz, 170kHz, and 200kHz

• PC Calibration & Firmware Upgrades: Flash-upgradable design allows field calibration via PC software to match specific transducer setups and hull characteristics

• IP66 Waterproof Enclosure: Housed in a durable polycarbonate case with M16 nylon clamping glands and EPDM seals for harsh marine environments

• Trip Data & Speed Tracking: Generates detailed trip data and tracks vessel speeds up to 50 knots with standard paddlewheel transducers
