Which explains why someone reported big-time ground loop problems
on a multi-floor net.
We really should do it properly. DC-DC for the AUI is my vote.
Digi-key lists a few - from US$10.00 to US$60.00 apiece. (In
quantities of 10 or more.) Wow. That's an expensive vote. Tell
me they're not that much...
There must be a cheaper alternative with Linear Tech, Maxim, NatSemi,
Motorola, and TI pumping out switching regulator chips.
