Today I changed the administrator password on a brand new NX-2200 from the default to a customer specific one and got locked out... I probably made a typo, although I could swear I didn't... Don't think I ever did that before in 20 years of AMX, but here you go.
I soon realised that login is required on the RS232 program port as default, so I couldn't use the 'resetadminpassword' option.
Something I read to hold down the 'ID' button, while powering on the controller, also did nothing.
Is there any way to recover from this? I know this has been difficult/impossible in the past, but not being able to recover from something so basic seems weird.
