Hi all, I have a few Ray 27's where Im only using 20 of the 27 channels available. im running LSP, E1.31 setup. The Rays are running through a D4. I should need to account for those extra 7 channels in LSP right? otherwise im thinking it will through all my dip switch address I've set out. So in the controller I drop into LSP, shall I assign it 27 channels but just use the 20 channels for the prop, so basically 7 channels will sit there unused? unfortunately its impossible to use all 27 channels of the controller in my setup, they are on one side of the yard to the other. I think that will cause a wiring nightmare. Am I on the right track.
