Hi John. I missed your question and just came across this when Wayne bumped this thread again. My apologies.
I never did get the DI working with the HW transducer installed (and various settings adjusted for it). Between the DI not working, and the SI/DI frequencies not maintaining their setting adjustments when the unit is power-cycled, I gave up playing with this process. I switched back to the older high speed transducer and left the selected transducer and settings stock. I was notified that there is a new update available, so I may play with this stuff again.
Hope things worked out for you...
