Axiom 9RV or 7DV to Airmar B744v

[rich59]

Is there an adaptor cable that will mate my existing Airmar B744v to either of my Axiom 9 RV or my Axiom 7DV MFD. The transducer was directly mated to a lowrance LMS5. The info for my transducer has 2 part numbers first being Lowrance #021-0073-00 and Airmar # 31-666-1-01. I was told by phone support that adapter A80488 was needed and was purchased. While being 7 pin to 25 pin it is not compatable. Second call was told the the same thing. The transducer connector has a number of Airmar 05-185-01. I purchased a RV100 not thinking of the performance issues with the boat being an inboard and nowhere to mount. I will be purchasing a pair of RV thru hulls when i can get the boat pulled. I am not concerned with the speed or temperature of the B744v at this time but i really need the depth for the time being. If needed i would waste the A80488 and try a splice if i could get a pin out drawing. I have the pin out for the 05-185-01 connector. Any help would be greatly be appreciated.
