SeaTalk is just NMEA 2000 with different connectors. You just need an adapter;

Thanks
So I should be able to get all the info that shows up on my SmartCraft display to be fed to my Axiom?

 

the Mercury Smartcraft connect will get you what you're looking for. It's not cheap, but will port all of your engine data, including your depth, onto your axiom on a mercury page. It can also be customized to work within the engine data pages on the axiom itself. https://www.mercruiserparts.com/mer...under-helm-kit?srsltid=AfmBOoq995EWF4PzdAOSSDc0hLMEuJoWYWXsgqwRlY1txiEGiA_HBdoJ

 

In that era of boat, you could have SeaTalk (may be referred to SeaTalk1) or SeaTalkng or even a mix, They are similar, but not the same thing and are based on NEMA 0183 and NEMA2000 respectively. Add to that your SmartGauges network. Depth could be on any of them. Based on the E80, I'm betting its SeaTalk 1, and you will need add a SeaTalk ng network. Not hard.

To do this correctly, your going to have to inventory what equipment is on the boat. First, do you also have a Raytheon Tridata (depth,speed, temp display? Also, do you have radar, a fishfinder, VHF radio, or autopilot? Your going to have to look behind the dash and in the bilge as well as knowing the type/model transducers will be helpful. There is likely 2, maybe 3 wired transducers, in the front of the bilge towards centerline.

If you have a Tridata (Maybe a ST60?) you can convert the transducer signals using a Raymarine iTC-5 and get them on a SeaTalkng (Or NEMA2000 with a pigtail). This is the basic layout, but your display will be your Axiom 9+ Using the iTC-5 will allow full/easy adjustment from the setup menus on the Axiom.

 

Smartcraft Connect, as was mentioned, will get you a lot of info including alarms and will run the custom Raymarine app on the Axiom. If all you want is raw data from the NMEA side then you might be able to just install a smartcraft gateway. For a 2005 340SDA you are most likely smartcraft for sensors and NMEA2000 for add ons although a previous owner could have install NMEA0183 devices if they were connecting to older equipment. You can bridge NMEA0183 to NMEA2000 too.

Another consideration about the Smartcraft Connect is that was designed to replace all other Smartcraft components and rely on MFDs for all displays. It will not drive your legacy gauges. As @KevinC says, I suspect all you need is the Smartcraft Gateway for getting your engine data on the MFD unless you are looking to add more MFDs and/or aux displays to replace your existing Smartcraft display device and gauges.

 

If you have SeaTalk1 you can also use the Raymarine SeaTalk to SeaTalkng 5 port converter. I connected my TriData to the ST1 port, a STng port via a DeviceNet converter cable to the Axiom 9. I get all the ST1 data (depth, speed, water temp and GPS) on the Axiom. This converter was my baseline setup when I bought the Axiom.

I also bought 2 tank sensor converters and via a switch box can I display Fuel tank levels on the Axiom or flip the switch for gauges. The #1 bonus to this is I can fill the tanks till it hits 100% and never spill a drop. Probably not applicable for you but I also added Fox Engine Gateways.
The same ST1-STng Converter comes with a different part number for connecting to a VHF radio to provide GPS data to the VHF, also via the ST1 port on the converter. Same converter different but instructions and part numbers. The one I was using for ST1 data died, so I swapped the cable to the other and it worked fine.
