This idea has been around for years.
You basically install a local area network in your airplane
and use these modules wired in series on a 3 or four wire
RS232 buss. The modules are placed wherever you need to measure
or control something. Some modern cars are now using
this idea. Saves miles of wiring.

My interest is in data acq for engine parameters like  oil/water
temps and pressures.  Almost any computer can then be used
for data acq.

The price for these modules is now about 1/5 of what it used to be.
