I recently installed a new Ev-1 w/P70, and a E7d mfd w/ i50 depth sounder. All connected via Seatalk ng. Problem: my i50 depth, powers up etc., but reads --- . The transduce is a P19 (I think) and is clean. The transducer is connected to the E7d and reads correctly on the MFD but not on i50. The transducer is clean. The only connection on back of i50 is a spur cable to P70 for power. Can I sync my 150 with the E7D? Why is my i50 reading --- ?
