heathwithnoteeth said:differential boards... you can put 4 outputs using the receiver board 250+ feet away from main control board. but you need a power supply for those 4 outputs locally. If that makes sense.
I actually have a differential expansion plus 4 receiver boards - if anyone needs some. I went with the normal expansion board instead.
I will be looking to go the differential expansion route this time. Just had normal board this year but the distance covering will be awesome.... What state are you in Heath?
