Perfect, Thanks a lot guys
I am wating to get the specific wiring diagram for my transducer from airmar, they had to have my part number on the transducer to find the correct set of drawings, because the m260 is produced whit diplexer, (signals 50/200khz on one pin) and whitout (signals 50/200khz on two pins), due to seperat 50 and 200 khz elements in the transducer.
I will report back as soon as i have made the cable and tested the configuration, probably next weekend.
I like this site more and more. Once again thanks!
