Re: Loops and Extended Buses

Doc,

You are not limited to 30 feet or less.  But beyound 30 feet you should twist the bus wires and add a R/C filter (snubber) to the end of the long bus.

Why....  induction in the longer wire will cause spikes and may fry a decoder.

This has nothing to do with amps.

I have read you can go 30' in any direction, even say a star 5 arms each 30' or less.
So what then is limiting the bus to only 30' in a single direction regardless of whether its power is rated 8 or 5 or 3 amps?
