North American AC Power Bar question

[blundr]

Unfortunately I think it's a problem with the outlet, it could be the relay or mosfet that switches it. If you want I can give you a diagram on what to check or you can send it back? I also see you ordered a couple of these, thanks, that's very kind of you.

Hi Rob,

I'm happy with the 7 working for now, assuming the new units will work with 8 (getting one for my buddy who has your robotank as well).  Do you know what the max length on the db9 cable is?  will a 15 foot cable work?

Thanks!
Matt
