Appreciate it, tried them all but no luck on this device.
@pturmel I would not be against trying that if this wasn't a demo model we were lent tor testing out the beginning of this project, but as such I don't want to take anything apart.
As it stands, it seems like we will have to upgrade all 12 HMI's to the next model up for some extra cost that allows you to rotate the OS from their built in configuration screen as I can not find a way to get terminal access otherwise. I appreciate all the help everyone.
The password +-+- is correct for editing the configuration using their UI but that is limited to what I can change. I am trying to get right into the linux OS directly as a root type user- that's what I don't have a password for. I am guessing doing so probably voids warranty or something as I would not be making changes through their interface. It's fine though, seems like we're just going to go with the other model so it's not a big deal.
They must have changed the root password before they lent it to us. It is a demo model, I'm sure they'll lend it out to others after we give it back and probably don't want people like us changing anything directly in the OS as such lol. Appreciate the research!
