Default $7,000 Raymarine Display and CHIRP transducers and no picture

Raymarine MFD e127
Raymaring CP450C CHIRP Pulse Sonar
Airmar B175-L and B175-H CHIRP transducers
Raymarine Adapter Box (Airmar transducer junction box)
Raymarine Sonar
Raymarine Autopilot

No sonar and CP450C was found to be defective. It was replaced and CHIRP transducers operated briefly until powered down and now will not power up. May be the Airmar transducer junction box as it is wired in between the two transducers and the CP450C to make the two transducers appear to be a single transducer. No help from the Raymarine dealer in my area whose people are good with marine electricals but no idea as to how communication electronics work in a networked environment.

The setup screen on the MFD show that it can see the CP450C box but not the transducer(s). There is also not the clicking noise that the CHIRP transducers make when operating.

Has anyone else experienced similar problems with this Raymarine setup or the Airmar transducer junction box?

Strange, I had the exact same system but the Raymarine transducers were matched specifically for Raymarine. So, there was no special box. I'm a bit worried that someone has gotten "creative".

You may want to call Gemeco for help. I know of no older CP450 setup were a box was used. Again, if there were from Raymarine, they had plugs and a y-cable.

Good luck with your post. I'm curious too.
