Hi Guys,
I'm in the process of implementing some simple control nodes (just switches) and looking for the simplest (cheapest) network protocol to use. To date, LIN bus seems to be the best candidate. I need very low speed, high reliability and low off-board distance (a few up to
10s of feet).Ideally, something that could be two wire with power and data combined would be ideal, so that the power could be distributed to power the slave nodes. LIN is good, but it requires a 4 wire (or 3 I suppose) interface.
I looked at ASI (Acuator Sensor Interface), but not sure how practical it is.
Anything else on the radar screen?
