First-Time Boat Rigging (Lowrance) – NMEA2000 & Ethernet Layout

[ZH1]

Hey everyone,


First time really posting on here, and I’m hoping this is the right place for this. I’m currently rigging a boat for the first time and would really appreciate a second set of eyes to make sure I’m on the right track. This might be intuitive for some, but since it’s my first time setting up a "Boat Network," I want to confirm that I’m not missing anything.
I’m confident in my power layout, but the NMEA2000 and Ethernet networking is where I could use some guidance, please see the photos.
Electronics Setup:

Bow:

• Lowrance FS12 dedicated to Active Target 2
• Lowrance PRO 9" for mapping/sonar
• Lowrance Ghost with 3-in-1 transducer
• TMC-1 compass

Console:

• Lowrance PRO 10" for mapping/sonar
• Point-1 GPS/heading sensor

Rear Transducers:

• Lowrance Active Imaging HD 3-in-1
• Lowrance In-hull 83/200 kHz

Questions:

NMEA2000 & TMC-1 Layout:

• Does my overall layout look correct? Is there a more efficient or reliable way to set it up?
• I understand that the power node should ideally be in the center of the network. Is my current placement centered enough?
• The Ghost runs its heading from the TMC-1 compass. Will having the Point-1 on the same NMEA network cause any conflicts or issues?

Ethernet and Sonar Layout:

• Does my overall layout look correct? Is there a more efficient or reliable way to set it up?
• With my current setup, will I be able to access all transducers (Ghost 3-in-1, rear HD 3-in-1, and in-hull) from both the PRO 10" and PRO 9" units?

Misc. Question:

• I've reached out to a bunch of mount companies but due to my console design (2006 Skeeter ZX200) can't effectively mount a graph nicely above the steering wheel. That being said I am planning on mounting the PRO 10" to the right of the console. I have ran RAM mounts in the past but was wondering how the Precision Sonar Lockjaw compares? The mounting face on the boat is at a slight angle—so, is the Lockjaw able to adjust for this? Basically, can the base portion be mounted at an angle while the graph mounting portion is adjusted to remain horizontal? I don't see this adjustability point in the picture online.

Thanks in advance for your time and help!

I can't speak to the Precision Sonar Lockjaw mount, but your NMEA 2000 and Ethernet wiring are perfectly OK.

I prefer to mount the Point-1 as close as possible to the transom mounted transducer, this improves location accuracy of way Points marked while idling around and scanning.
I set the console graph GPS source and heading source to Point-1 but the bow graph GPS source is set to internal while the heading source is set to Point-1.
I prefer to set the NMEA 2000 network up this way so I can easily add components anywhere on the boat by just adding another tee and a short drop cable.

I would run the AT module Ethernet to the 9 HDS instead of the FS. Then connect the 9 to the 12. This way all your shared waypoints will be available to the FS. Simple matter to select the AT image off the 9 to show on the FS. NMEA looks good but preferred location for the Point 1 is at the rear. I agree with Bill. I like the. NMEA network to be infinitely expandable. Point 1 and TMC-1 will not affect each other.

Thank you all for reviewing this. These are some great tips/ ideas and I will definitely implement these. This answers my questions of how to get all 3 units to share waypoint and information.

I've update the Ethernet layout.

Looks better IMO
