I was looking at simple KT LED displays and it seems to change parameters you have to use a KT LCD display and parameter transfer cable which connects both displays with a little cable going off to insert the necessary power. Anyone have experience of these. Are there easier and better solutions especially if the displays in question actually have the round waterproof connections rather than the connectors shown in this diagram. I've never seen such a cable for sale but admittedly I haven't been looking for one. I like the LED displays for simplicity and durability but seems like a lot of hassle to set them up. I guess most people use them with the default settings? Yet from what I understand they can hold all the parameters just a like a normal LCD display and they function better if properly setup.
