MLO 48 & MAIN 40 support

I have 2 SPAN Panels - a model 00200 and a new MLO 48. 

The 00200 is discoverable by the integration, but I am unable to connect to the MLO 48.  The panel also does not answer my web browser and throws an error 404 when trying to attempt to get to the login page. 

Looks like it is probably a different version of software on the new panel - should this panel work with this integration? 

Thanks
