Wow! If that's the case, that is potentially dangerous... imagine having that
tied to a real world device "launch missiles" and it fires on reboot :-)
I would talk to Eddie at TS and see if he has a comment. I expect there is a
config somewhere... I don't see them missing a design flaw like that.
Plan B might be to install some sort of solid state inverters, and then you
program 1 = off, 0 = on.
Good luck,
