Fellow wrenches,
I have been following the AC coupling discussions with interest, and
now have a site where this would make a lot of sense. One question
remains that I have not been able to answer by reading the archives I

Jason,

Still waiting!
Thanks,
Fellow Wrenches,

inverters to a PC for data acquisition and/or control. The cabling
