I'm trying to help a neighbor with his NN3D system, and ran into some problems relating to the DFF1 fish finder.
When running the MFD12 in Installation mode, the DFF1 is seen, and shows the transducer (Airmar B744V 50kHz/200kHz triducer) to have TD-ID. But both HF and LF are 50kHz/600W, in gray, and can't be changed. Any ideas what the problem could be?
He was using it with the non-NN3D setting for the DFF1 and the power synch switched off in the HUB101. It seemed to work fine with the one frequency. I switched the DFF1 to NN3D and the hub to power synch for both MFD and DFF1, and the DFF1 came on when the MFD was powered up as it should. The same transducer problem as above was seen but otherwise the installation seemed OK. Then the sounder display showed a connection error. Back in the menu any attempt to adjust the DFF1 settings, or reset to factory, kicked out an error which had not been described yet. (Hint to all S/W engineers: put something useful in the error messages when first programmed because you won't do it later!) Any ideas as to what is causing the problem? BTW the LED on the DFF1 is doing the 2 second blink as it should.
Thanks in advance.
