The ePlex system was used by Newmar (through MY2011) to manage the house and chassis functions on their highline coaches.

Our RVC (Can-Bus for RVs) system has been used instead since MY2012. In theory and practice these ePlex versions can be retrofitted to the same RV-C system. In practice, we've converted one, Newmar one. We each found it's ...difficult... A refit for a system with lighting/shades (etc) requires a significant tear-down and more than a month if a small team is available. We don't have that available. No one does ...however...

Newmar has put together a 2019 'Owners Guide' for each of the newest highline models. These are more similar-than-not to the previous models and so are quite valuable. While its a bit large (approx. 12MB) the helpful detail can be seen here for the New Aire Owners Guide or the King Aire version for the expanded package.
