Authentication

No password configuration required. The driver automatically tries the known Christie defaults (1111, 0000, 1234) on connect and remembers the working one for next boot. If none work, an Authentication Failed event fires and AuthStatus reports "Failed" – the panel password has been changed via OSD and must be reset to a default.
