Adding EV100 to Seatalk network

[Bikerbob]

Looking for some help clarifying how I should wire this.

I have.

Ev100 - p70 head evsensor and acu100 (all on seatalk ng)

St60 depth and St60 wind

Garmin 441s GPS

I am making a pic of the system on the computer, and will add to this thread tomorrow.

But What I am looking to do is use just a seatalk1 to ng cable from the P70 to say depth then depth to wind then wind to the seatalk/nmea bridge(which has the Chartplotter off of it). Then the other side of the p70 to the ng junction which would have the ev sensor and the acu100 also running into it.

Now as I understand it.. the ACU100 cannot power the ng network. So I need to get power into the junction - so could I run a backbone cable to a T - run a spur to power off that.. and that would power the ng network? I then run separate power into the ACU100 so that can power the wheel drive.

Does this sound correct? or do I need to get a converter KIT in here somewhere??
