NMEA 2000 questions.

[A1an]

Firstly, where do people power their network from? Direct from master switch? Can anyone see a problem with using power from the same switch that powers the GPS. It would seem the logical place as all N2k data will be displayed on the screen.
Secondly, do I have to power the network from a T or can power from the end of backbone? Some say yes, some say no?

I’ve always powered via a “T” never herd of powering from one end. Can’t see how that could work, where does the terminator go? Accepted wisdom is to power from a T in the middle of the back bone. My network is powered from the fuse box via the isolator. As soon as the isolator is on, the network powers up.

*heard ffs. Autocorrect

Similar to Dave, I've never heard of the network being powered via one of the terminators.

Mine is powered via a switch that provides power to the chartplotter, AIS and NMEA 2K network simultaneously.

I only have the chartplotter, VHF and AIS on the NMEA 2K network and no engine related stuff.

I've been looking for the pictures that I saw the power being delivered from the end of backbone but cant find them, I've googled a lot of N2k recently.
I've now got it wired via the fuse panel.
I only want the network for engine data and depth transducer on chart plotter. Not enough room on console for both Command Link gauges.
Thanks for the help. ����

Mines is powered through the tee if you are buying the stuff go for the 4 branch tee set up far neater if I get a chance I will put up a picture of my gubbins under the dash

I’ve had the bits and pieces for a couple of years but never got round to putting it together. Spent today sorting it out and the engine is now talking to the Garmin displaying nearly every engine value known to man.
I can overlay select values on to the navigation screen which is handy.

I do need a 2m drop cable though. Can’t believe the price!!

Always use a 'T' power cable with fuse please.
