Hello, I have a need to put several pics on parallel lines. I have to go about 1000ft, so I plan on using rs485. What size wire should I use to provide power to these pics? I was going to use 6 conductor cat5 cable. This is what I was planing. Use 4 conductors for data and pic selection, the other two would be for power. I would call a pic by using an and condition on two of the wires to select the pic. The other two would be used for communications. Anybody done anything like this? Brian Gracia
