Dear friends:
I would like to ask you for your help in the following:
I have a programmer for watering my garden that is far from it. The plastic tube that conducts the electric wires from the programmer to the electrovalves is blocked and is impossible to add more cables or even to pull them for using as a guide. Now, there are 2 electrovalves that are controlled by 3 wires from the programmer (one mass). The problem is that I would like to add 2 more electrovalves. As it is impossible to add two cables, I am wondering if you see any method to convert the signal that generates the programmer for four valves (the programmer can control up to 4 valves) in a binary code who travels along one of the cables. Then, in the garden demodulate the signal convert back in a signal for 4 electrovalves. The other cable should be used to provide the supply for the valves (26 volts AC).
Thank you very much for your help
Arturo
