Yes, the info and all other protection is disabled when I use the bypass but surge protection is still enabled.
The Honda supplies excellent steady power to the degree that a computer can be plugged into it directly without concern. After reviewing the output specs, I have little concern about needing the EMS for reverse polarity, frequency protection or open neutral issues. I've used it this way for 2 years with zero issues.
That said, just because something hasn't happened doesn't mean it never will. John Kohl's advice to seek a certified electricians input is solid.

Thank you for your answers. Our Progressive Industries EMS-HW50C manual says that the bypass switch on the remote "allows AC power into the RV in the event of a computer failure; it does not disable the surge protection portion of the EMS; however, all other features are disabled." If there's someplace else in the manual or in a separate remote manual about flipping the switch when connected to a generator, we missed it, so never thought to try it.

Jay, thanks for letting us know that this is the solution with your Honda. Are the "features that are disabled" the power info about voltage, currency, frequency?

John, thanks for your concern about our safety. We do not intend to muck about with something as dangerous as electricity if we don't know what we're doing. I asked for clarification about making a pigtail, not necessarily in order to make it ourselves, but in order to know exactly what was meant by it so we could (somewhat) intelligently discuss it with an electrician. The electrician who installed our EMS was someone we knew and trusted who was familiar with trailers, EMS, etc. Before approaching someone we don't know here, knowing exactly what's needed to solve the problem (if, in fact, we do need the pigtail unit) would make us feel more confident that the person would create just what we need.

Thanks again for your prompt responses.
