DST800 triducer nmea2000

Anyone had problems with the speed output of these units. I have had two go bad on me.
Is there a test for the output with a multimeter?
Or, the wheel magnets?

Re: DST800 triducer nmea2000

I had a DT800 (no speed) where the temp sensor went bad. I just replaced with a DST800 and the speed reads about 50% too fast. So pretty useless so far, but I've made no effort to figure out what it's so far off. Reading slow I could understand, but reading hight seems very odd.

I haven't looked at the sw but I suppose it is not possible to apply a linear or other correction, only a constant offset? Which obviously wont work for 50%.
I suppose you could always apply the 50% for normal cruising speed and then you will be reading high below & low above. OMG, we pay money for this?

A reading at all would be a start for me. Instead of dashes.
I'll try with reading the output in nmea reader and then apply the latest firmware & hope that lights it up. Latest I believe is " DST200_a1_1022"
The Zeus default to sog is annoying.
I bought mine several years ago and only recently installed them, so no rma.

Re: DST800 triducer nmea2000

I have this triducer relabelled by Maretron and it works fine. I can program it from my Maretron display or using the computer with the USB100 gateway.
The Airmar version can be programmed with the Actisense USB gateway I think? I use that for my Airmar heading sensor.

Re: DST800 triducer nmea2000

My dst800 has a lot of calibration options from our Raymarine i70. You can create an offset for every speed if desired. It also has an option to calibrate it to SOG if you can find a calm stretch with no current.

Re: DST800 triducer nmea2000

I have a DST800, my speed is slightly fast but my simrad MFD can compensate for that. The worst is the water temperature , that cant be adjusted so I will have to buy a temperature only sensor for that.

My DST800 water temp is also useless. I can calibrate it with my instruments, but it is so nonlinear that the calibration isn't useful.

The triton T41 has two types of speed calibration; related to percentage of SOG, and measured distance. I don't know which would work out best for the linearity or non of the error. What control heads do you have?
What is the importance of sea temp?
Oh, Toronto...say no more.

Re: DST800 triducer nmea2000

Less than a year later, my replacement DST800 has also failed, now reporting no temperature. These things are junk, and Airmar wants me to remove mine and send it back before they will provide a warranty replacement. That means showering my ER in salt water, which I'm just not going to do. So I'm done with these things. They suck.

Re: DST800 triducer nmea2000

I have the DST800 from Garmin.

Speed is OK except when fouled.
Temperature no longer works at all.
Depth seems very weak, I never get a sounding over 50', even with a perfectly clean transducer.

I will not be replacing it with the same unit.
