So i purchased a Y cable to use on my Helix G3N SI unit so i could connect the ultrex MDI builtin and the mega 360 on this unit and leave my other helix to show mega live at the same time. Got on the water yesterday finally, and only the mega 360 would show up, no DI/2d. Restored defaults, power cycled a few times but nothing.
Any suggestions?
Thanks
Scott
