I got some Microchip CAN transceivers and some Stellaris Launchpads from TI. I would like to learn how CAN works. It looks very nice for what I want to do (one controller per room, controls lights, vents, etc.)
Anyway, my real question is, while 60 ohms is the impedance recommended for CAN, can I use 50 or 75 ohm coax cable? Googling it didn't yield anything much for me, nothing definite.
So I can just run a coax cable and T it off instead of passing through (or splicing the cable I guess).
Coax seems a nice clean way to do it, but since it's not talked about I am missing something, I imagine.
