fyi
The bad news:
I did the same thing only to realize that the sonar unit in the Spectra
uses a custom IC to control the transducer. The receive or analog IC
is the same as the commercial ones.
I did find out the pin outs to the connector but unfortunately I don't
have my notes with me they are at work. I did some experimentation with
the unit, but due to the custom Logic IC only one ping can be initiated
at one time then the whole board must be power cycled to reset. Other
than the above problem the unit works!
The good news:
I solved the above problem by replacing the custom IC with a Texas
Instrument TL851 IC and now I have a sonar board that is much cheaper
than buying one for $50.
As for the pin outs I'll get my notes and post it ASAP.
