Perfect. I’m connecting a Lowrance Point 1 to a Garmin fish finder. This answered all my questions. Thanks for putting it together.

[@irishtower]

Beautifully clear explanation. Thanks!

[@fatandyboy6856]

Such a great explanation - well done!

[@BenitoNsx]

Well explained, thanks!

[@PittwaterMowing]

Great easy to understand video Thanks for the tips

[@rongmeiner329]

Great for starting to understand.

Great video... well explained thank you.

[@Mr.Pasbon]

Great video by the way .

[@kevincrawford6936]

I'll have to say that this was one of the best how-to videos I've ever er seen. Very well explained and demonstrated. Now even a caveman can do it 🤪

[@jayjohn52]

Thank you!

[@MrGambitx13]

If the can connectors are loose will that keep my hds unit from turning on?

[@walterbatalhacameira3917]

Hi, Im change my old GPSMAP 20xx per an new GPSMAP 7400/7600 series and I can use an GSD 22 with Him? how to install GSD 22 on GPSMAP 740/7600?

[@adamhrubie5738]

Can I plug something in to either end of the backbone? Or does it have to be a resister?

[@chuckcelestine6558]

Hi, love this video. My name is Chuck and i have an 1825 Jetcraft Falcon and I bought the NMEA Starter kit, for all I care to hook up is my Lowrance display, and my vfh radio. So does these units need to be on a separate battery? Please explain Thanks

[@guydauderman1645]

Where can you find a list of manufacturers devices that are NMEA2000 certified?

[@stathisyannacopoulos3004]

What is the max power I can withdraw from the NEMEA network and avoid a separate power supply? I wish to connect a AIS transceiver (em trak 953) to my network, should I take power from the network or feed it with a separate power supply?

[@Mr.Pasbon]

Do I need the power T supply if I am going from my engine directly to my gps, which has a power supply of its own ?

[@neillee3793]

You mentioned separate power needed to the multi-ruction display correct? Your example did not include that correct?

[@zash008]

I just put together a network on my boat. One end of the 'backbone' has two power leads that connect to battery. The other end must have the termination cap. In-between the power end and the termination end is your T's that each 'drop cable' connect to and each device. So if you have and un-used T it is easy to just remove that T until you have another device you want to connect. The network is easy-peezy to build and make work. Without the power end and the termination end, the network will not function.

[@Shanester66]

So do you have to run separate power to the fishfinder or is it powered off the connection to the backbone?

[@toobglued]

its powered separately. they draw too much. also he states this. ;)

[@DavidReySilva]

What is the model of that Garmin mini mfd display?

[@Jerryh31]

Do you have to use all four ports on that tee or can you put a terminator in the unused ports? I heard there should only be two terminators in the entire system.

[@Jerryh31]

@csrgatorfan From what I can find online, the unused ports can be left open. Only the ends of the backbone cable need terminators.

[@fishingismydrug1]

On the multi port, would the unused spot need a Terminator? Or is that only for the ends?

[@stevenderusha6421]

I have the same question about terminators on unused drop tee,s.

[@returner323617]

No: you only connect a total of two (2) Terminators to the Backbone; one at each end of the bus. Generally speaking, you would not have any unused/unnecessary Tees on the Backbone, as each connection introduces a small degree of loss. The best practice is to have the bus built using right-sized cables (in terms of length, not excessively long that needs to be coiled, or lots of short lengths extended by Tees), and just the right number of Tees.

[@ricardonunesdesouza2621]

I need to buy 3 instruments for this engine of mine etc. 130 evinrude this product works and what is the price, do you deliver it right there in the USA,

[@DamianT361]

So if I have an open port on for way will that prevent communications ?

[@DamianT361]

Four!

[@DecisiveOutdoors]

If I am only running a GPS antenna to my display do I need to run power into the backbone?

[@TheGPSStore]

If the antenna is NMEA 2000 then yes you do.

[@DecisiveOutdoors]

The GPS Store, Inc. right on, that what I figured. Thanks for the reply

[@jackwebb111]

If you only have one NMEA 2000 accessory (such as a SteadyCast Heading Sensor), is it necessary to build a "NMEA 2000 Backbone", or can the SteadyCast plug directly into the chartplotter (741xs)?

[@TheGPSStore]

Hi Jack, if you add any NMEA 2000 accessories or components it is necessary to build a NMEA 2000 network. the easiest way to do that would be to buy a NMEA 2000 starter kit.

[@jolantakusmirek3128]

Jack Webb nme

[@zash008]

I learned if you only want to connect two devices as in your yamaha engine to your simrad you indeed still must build the network.

[@jimmybranca5795]

Can you add more than one transducer and does it matter what order components connect to the backbone?

[@michaelbirch9265]

I have a Nema backbone and unlike your video, I cannot connect my Raymarine instrument to it. The Raymarine has a 6 pin plug and the Nema has a 5 pin plug. Can you tell me how you fitted that Raymarine device to the Nema backbone?? Maybe you used a specific connector but you did not explain that.

[@SF-rl7hl]

Your Raymarine is Not compatible with NMEA. must be 5 pin setup.

[@michaelbirch9265]

@@SF-rl7hl only took a year for a reply. Awesome support

[@russelldevane5434]

All I want to know is how do I hook my Garmin 94sv up to my new 2020 50 horsepower Mercury so I can get all the data on my depth finder screen

[@benlyons5884]

How this technology is still being used is beyond me. So old school. Bluetooth and wireless is here!!!

[@theottovanpagel]

Ben Lyons everyone does not have that option boat is too big wireless does not reach.

[@benlyons5884]

@@theottovanpagel unless you're on a 40+ footer, wireless is fine

[@theottovanpagel]

I agree but I’m on a Westsail 43 with a 54 foot from the deck mast. Wireless does not work that good for me.

[@benlyons5884]

@@theottovanpagel nice yacht. Your helm is only about 11 feet from the stern, which is where all your sensors would need to be. Id imagine you'd have no issues if you needed to set up a wireless connection between a sounder and sensors. However, we should invent a wireless system first 😁

[@minibar7165]

I noticed on the four way drop, one was left unused, I think it also needs to be terminated with a resistor ....

[@coffinsa]

He has it wired correctly

[@anchorsandpilots6850]

Not much help.... seems way too much work

[@zash008]

One of the easiest things you can do on your boat. Its like connecting legos. It just looks complicated but its not. One end has the power leads that connect to battery. The other end has a termination cap. In between are T's that cables from each device connect to. Thats it. Period. If you remove a device just remove that T also and done. Add a device? just install another T and connect T to device with a cable. All the devices are connected at T's between the power end and termination cap of the network. Thats it and it works.
