For Axiom 9 plus addition do I need an iTC-5, Seatalk ng adapter or both

[pilot1995]

I'm adding an Axiom 9 (replacing a Raymarine Dragonfly) and adding a Vesper Cortex. I believe I need an iTC-5 converter but do I also need a seatalk ng adapter?
Here is the current Raymarine Equipment I have using Seatalk 1 and Seatalk ng

Autopilot Control Head ST6001
SmartPilot Autopilot
i60 Wind Display,
ST60+ Tridata

The ITC-5 takes the analog readings from legacy equipment (masthead fly, knot sensor, depth sensor) and converts it directly to SeaTalkNG, where you can display it on any multi-function display.

You will need a Seatalk-SeaTalkNG converter to keep your legacy autopilot and TriData display in the system.

With the state of your system right now, unless you want to eliminate the long runs of analog wiring through your boat, the ITC-5 will do little for you (except maybe give you more room in the tubes for the pedestal guard, since you can replace three analog wires with one seaTalkNG wire). The individual SeaTalk instruments will put it on the SeaTalk network, then the SeaTalk-SeaTalkNG will convert it so it talks to your Axiom.

Here is mine after a series of upgrades has almost eliminated the SeaTalkNG converter entirely.

This was stage 1 of my update, that more closely resembles your system. Stage 2 was swapping the legacy chartplotter for the Axiom,

What you have is an ST1 network. The STNG cables also carry the ST1 signal and that’s what you are using. You will need to build a STNG/N2k network if you want to connect your current instruments to the Axiom. Either the iTC or the ST1-STNG converter (E22158) would work. I am using the converter and it would keep you from having to remove the transducer wires from the instruments to feed the iTC. I don’t know if the Smartpilot can be controlled by the Axiom if it remains ST1. I bought the STNG Smartpilot cable to connect to the STNG network. I would follow TimMarks stage 1 except connect the Smartpilot course computer to STNG.

Thank you for all the information. I'm not too concerned about controlling the SmartPilot from the Axiom. I'm more interested in seeing the data on the Axiom. The diagrams are really helpful too. I think I'll go with the Seatalk-SeaTalkNG converter and pick up the necessary cables to do the job.

Everything your asking is covered in the ST NG Reference Manual... SeaTalk1 to SeaTalkNG Manuals | Raymarine

Make sure your networks, when connected, have a single power source! Often the ST1 power comes from the Autopilot Computer.... I'd remove that power and power everything from the middle of the new ST NG network.

The big advantage of the ITC 5 is you don't have to pull 3 wires from the mast/keel all the way to the helm, only one ST NG backbone.... Then the ITC 5 can be in the cabin near those sensors (behind the nav desk?).

Don't put the power into the SeaTalk converter, even though a power cable is supplied with the unit. It will eventually fry the circuitry inside the converter. I was on the 3rd converter when I got that answer from Raymarine.

I am powering the STNG/N2k network from my ST1 instruments, thru the converter. Works great and this way I don’t have to keep the Autopilot powered at anchor if I want the network up.
