Quote from: magnethead794 on Dec 15, 2011, 06:53 amAny Answer?Sure, twisted pair wire may cause more trouble than help. Get 20' of four conductor telephone wire and give it a try using three of the conductors for tx/rx/gnd.
Phone wire will plug into an RJ45 right? I just have to find the 4 conductor wire? (I'm assuming put Rx and Tx on the ends with ground in the middle?)
If your signal is relatively low bandwidth you can get away with longer distances - but the receiver circuitry needs a low-pass-filter (R+C) and schmidt-trigger to filter out the high speed noise and reflections and generate a proper logic level again. If you want to send logic speed signals (10's of MHz) then you have to use the cable as a transmission line with proper line drivers and receivers.For 10 feet you may get away with it.
