This drawing I cut and pasted together shows the network powered from an end T and different NMEA2000 device locations.
Powering and device placement and terminations are common on all compliant NMEA2000 networks.

Just so there is no confusion. Shouldn't the T with power on it be a "power node"? Unless they've changed it since I did mine several years ago you can't power it through a regular T. Also the terminators are not the same, there is a male and a female for a lack of better terminology.
The Ts are all the same. Nodes are just points of entry/exit from the backbone, thus the "power node". Since the backbone T are arranged in a Male/female in-out arrangement, the Terminator resistors are also male/female arrangements. This coincides with the beginning/ending of the backbone nodes. But, of course, some numskulls can hook it up wrong. The connections are really straight forward.
When I did mine I had never seen any of the parts that make it up. What I ran into was numbskulls that didn't know anymore than I did selling me parts that I didn't need or that didn't work with my application.
I understand your message. If you call Lowrance for HDS help, there is not much knowledge of NMEA. The installation drawings kinda suck too.Quote:
