CAN Bus Design Guide

[mbell20688]

I am installing two TZT13X MFDs, a DRS6A-NXT and a Hub-102. I found a document on the Furuno USA website called 'Furuno CAN Bus Network Design Guide', document number TIE-00170-B, which emphatically states the Furuno equipment should have a single connection to the CAN bus. All other inter-device communication is handled through the Furuno Ethernet bus. This differs from the network topology in the TZT13X installation manual which clearly shows multiple MFDs connected through the Furuno Ethernet bus and each with a connection to the CAN bus. Which is correct?

They need their own connections to ethernet and NMEA2000.
Some things can be repeated over ethernet to the other devices, but they might as well listen to it first hand by being on both networks.
I'm guessing the document referenced is for older equipment.
