We have recently received a used Kuka KR 60-HA with a KRC4 controller. I've plugged everything up and the computer and smartpad boots fine, all three icons at the top are green, but it says "Could not initiate robot interface. Please turn keyswitch." when I turn it it says "no HMI" under my robot. I also get an error message that says "Invalid RDP credentials. Invalid credentials received from spartPAD service."
Since these all seem related to the computer, I plugged up an external monitor (had to put a graphics card in first) and while the monitor is working, after booting it goes to a black screen with flashing underscore in the top left. Going to BIOs / setup doesn't seem to help either.
Not sure if this is a controller error, windows error, or error on my part during setup. The computer seemed to be in working order when we purchased it.
Thank you for any help
