Ok I finally got the correct Axiom 9 with sonar capability. I have not yet been able to haul the boat to install the RV transducer. In the mean time I was hoping to use my already installed airmar b744v transducer. I have purchased the appropriate Y-cable as well as the 7 pin to dsm300 adapter cable. I hooked everything up but the Axiom does not detect any sonar connected. The airmar transducer worked fine with the previous C90w/dsm300 setup. What could be the problem here? Is there a way to diagnose the transducer by testing between different pins for ohms/resistance values? Is it possible that the RV transducer needs to be connected as well to complete some internal circuit? Thanks again for your help
