ST60 and ST50 on the same network

I've fitted an ST60 wind, speed and depth in the cockpit which is attached via the Seatalk network to ST50 Multi, Autopilot, GPS down below. I tried to calibrate the ST60 wind transducer at the weekend (going round in circles until I was dizzy!) but it wouldn't calibrate. I had an intermittent alarm sounding on the ST50 Multi and it refused to move away from reporting wind (it will also display depth/speed etc). Do I have a conflict arising between ST50 & ST60 here? Anybody with any experience of this?
 
There is a compatibility problem between some ST50 and St60.

For instance I know that ST50 masthead unit is only compatible with the early ST60 instruments. I am not sure what Raymarine changed, but our early ST60 wind reads Ok with the ST50 masthead bit we inherited, but a later ST60 is no good. You may have to check with Raymarine. They are normally very helpful.
 
When you say calibrate my reading of the ST50 wind system is that you navigate in circles making sure that the indicator always follows the wind direction and then you calibrate it to the heading by use of the keys on the instrument. Is this correct.
 
The ST60+ does not make mention of the pointer moving around as does the wind; it simply says "drive in circles" and this will automatically calibrate the head transducer. I have aligned the pointer to the wind direction but I still get the CAL flashing in the head unit (an indication of calibration needed apparently) and also the wind direction which is passed to the Seatalk bus is nonsense. I repeat the wind direction on various instruments and it appears quite different to the pointer indicated direction, Confusing stuff.

I had a problem with calibration of my ST60 wind instrument it turned out to be low voltage in the supply apparently its quite critical. I eventually diagnosed it with a multimeter and a Raymarine technician on the end of a mobile phone, as said before they are extreamly knowledgable and helpfull. the solution was to put in a second power supply at the end of the daisy chain. It was well within what the handbook says in terms of no of instruments but the addition of extra volts cured my problem.
 
Pete; very helpful, thanks. I'll test the voltage on the Seatalk network. I've asked two questions on the Raymarine site but I've had no response from them as yet - and I can't find a telephone number to call. When you say you had him on the line - was it a guy from Portsmouth? And if so do you still have the number please?

I just broke my ST50 Tridata /forums/images/graemlins/frown.gif and my ST50 Wind has a load of condensation in it, so am thinking of pushing the boat out and getting new ST60+ heads for both.

BUT will the existing transducers work? From reading this thread (which is better than the Raymarine Knowledgebase!) it would seem that this would work ok.

Does anybody know for sure that the ST60 Plus Tridata will work ok with ST50 transducers. The Raymarine site says the ST60 Plus wind works with ST50 masthead - but does it really?

All comments and thoughts greatly appreciated!

All I can say for certain is that the speed transducer will work with ST50s and 60s. I know 'cos I've just done it. I believe that wind and echo also work but I've not tried it.

This was what I suggested to you on the other similar thread PBO. Try it!
 
I asked the same question at Greenham Regis just recently, as I am also faced with the need to replace wind and tridata. They told me without any hesitation that ST50 and ST 60 are compatible across seatalk, I suspect though that the ST60 head unit will need a ST60 wind transducer.
 
Thanks - glad to know i'm not alone in this!

I am reading all the threads and there are clearly some compatibility issues around wind. The Raymarine site simply says "ST60 Plus Wind Display only. For use as a repeater or with an existing ST50 or ST60 wind transducer" - but it would appear not to be quite true!

I had a problem calibrating a wind instrument and it was because my boat speed was about the same as the wind speed. At one point in the circle the cups stopped spinning and the calibration failed. When I repeated the exercise travalling at a slightly higher speed, it worked OK.
