Powerful Digital Signal Processor
A high-speed microcontroller capable of 4 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.
A thermistor can precisely measure the water temperature around the transducer, with a 0.1°C resolution.
IP66/IP68 Case and Grommet Design
A robust ABS case with a high waterproof certification. The small case size is ideal for space restrictive applications.
Depth: connects to a standard piezoelectric depth transducer crystal element using a three-wire interface.
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.
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.
