I think you may need separate networks if it is not the same protocol, but i am not sure
Thanks,
I will contact the manufacturer and ask them more for this connection.

On an correct Bus, like your Bus on the Boat now (also powerless, not active) the Multimeter should read 60 Ohm - with Terminatorresistors at both End from the Busline.
Good Luck

Thanks for that.
I will check soon
