Furuno sounderto raytheon cable-gctid353472

[Guest]

Guys I have an old CRT Furuno that I am trying to wire up to a rayTHEON 7 pin ducer (with a foil shield) .

There are a white a black and a braided (ground??) coming out of the furuno. I am getting a good picture but wave-patterns (like moire) on the screen and it loses bottom over 60 ft. Using butt connectors and going ground to raytheon shield (no other option I can see) Anyone out there got a direction you can point me in to make this connection a little better?

Try the Airmar site: http://www.airmartechnology.com/2009...ch.asp?Type=FF

Or try GEMECO, Wholesale only, but often very helpfull. http://www.google.com/url?sa=t&rct=j...OTFERZkb3O-HPA

Theres more to it than wiring it. Are the frequencies the same in both units?

Is the power output of the two simular? Are both outputs balanced to ground or coaxial?

Its not as easy as just wiring it to a plug.

Power similar, frequencies same. I think it is the difference in shield vs ground. How to work around it? Hmmm

Some transducers excite differently and are just not compatible with certain sounders.

Arimar.com has a good cross reference.

As was posted above, some use a signal to ground, some use a differential signal, some use separate elements for the 200 and the 50 KHZ frequencies.

Some older units even use different frequencies.
