Siemens FC922 Panel

You’re gonna have to call in a Siemens dealer. There isn’t anything you can do through the keypad.

Did a monitoring takeover on a Siemens FC922 panel. Disconnected the batteries and down powered the panel to tie in the dialer. Upon reboot I got a trouble stating that the RS485 module was now a unconfigured device. I have maint level access to the panel and wanted to know if anyone has run into this issue and would know how to resolve it.
