Warning: Depth sounders are not designed to perform as navigational instruments or as devices to avoid grounding a vessel. Any such use of the Actisense depth output is at the vessel owner’s own risk and no responsibility will be accepted for any resulting boat damage or personal injury. -
Page 4: Introduction
The Actisense NMEA Depth sounder / Speed log / Temperature sensor (DST) product was developed to allow the connection of a standard passive (no electronics) depth sounder transducer to an instrument with a NMEA 0183 digital data input. The Actisense DST interfaces between these two otherwise incompatible elements. -
Page 5: Connections
Pictures show the 150kHz model. The 200kHz & 235kHz models are identical, but use the label “Actisense DST 200” and “Actisense DST 235” respectively. Referring to figure 1 & figure 2, from left to right, the Actisense DST has connections for: - 1. Battery supply input. -
Page 6: Connecting A Speed/Log Transducer To The Dst Box
On Airmar “Triducer” type sensors, the log and temperature sensors share a ground pin as a return for the signal, and as the negative supply. The Actisense DST also designed to share this same ground return. If the required... -
Page 7: Connecting To The Battery Supply
Cable exits The Actisense DST box is provided with rubber sealing grommets around the edge of the box. It is recommended that the box is positioned with the double grommet at the bottom of the unit, so that two wires may exit downwards from the case. -

Page 9: Using The "Flash" Upgrade Facility
Using the “Flash” upgrade facility Availability The current Actisense DST software program is a mature product that has evolved over the past 5 years, and as such, we believe it has been tested more rigorously than any other depth sounder device currently available. -

Page 12: Compatible Transducer List
This is list is by no means exhaustive. Airmar have brought out many new transducers to the market, and any of the 200kHz and 235kHz models will work with the Actisense DST (Depth / Speed / Temp) module. The 150kHz model has been tested with the following manufacturers transducers. Seafarer transducers are essentially the same as the NASA model, so should be identical in performance, although we have not tested one as yet. -
