Interesting Mike, mine shows No AC on the Aladdin. I do show battery information but no 120 information. They are installing the new one right now. I’ll ask the tech if he noticed a cable. I do have the ATS module but there is no cable feeding it.

I just double checked my Transfer Switch (as best I could with the limited space and visibility) and there is no data cable coming out of it (I don't even see a data port). Maybe that data port was an option for the TS).
I have a photo of my tank area where the Aladdin modules are located - and like you, I have the ATS module but I don't see anything plugged into it either.
I do recall Steve or Gerald or someone more familiar with these coaches saying the voltage/amperage is read off the "feed wires" at the main circuit breaker panel. If that is the case, and your not seeing any data in the Aladdin display perhaps you need to remove the CB panel cover and have a look in there (probably not a bad idea anyways if you had a large voltage surge)
BTW - just took the covers off the inside breaker panels to see if there was anything in there for measuring current or voltage - and there is not.
