Is this a hopeless cause?

I have been making some improvements to my new to me O'Day 322. Installed new Mack Pack, replaced the STB rope clutch, replace the strut bearing, etc...
I have been looking over the instruments, which are a hodgepodge mix of stuff:
Data marine speed / depth (old)
Raymarine St4000+ AP
Tac Tic NM30 wireless wind
Garmin 740 chart plotter

Nothing seems to talk to,each other...
-can't hold a wind angle with AP ( no wind information)
-can't display true wind on NM30 ( no boat speed information )
- can't display any auxiliary data on chart plotter (wind, etc)

In looking at the wiring this weekend, I found what appears to be the start of a "network" backbone....


I am still tracing the wires that connect to the backbone, but will these instruments actually talk to one another, or do I need to start standardizing on 1 manufacturer?

What is the easiest/cheapest way to get AP and NM30 wind instrument to talk to one another?

As a general rule the only way to get things to talk to each other is to use a NEMA format. Pretty sure most of your stuff is not going to talk NEMA 2000 so 0183 is all that is available. 0183 is a many listener single talker protocol. So the wind is a talker to the AP listener. Given that the wind is wireless I'm pretty sure you have to take the NEMA off the display head. Check the manuals.
All the other talkers, depth, speed and plotter/gps would need a completely different listener port on the AP. The Ray AP may have two listener ports or one listener and one talker. The talker would probably want to go to the plotter to confirm way-point arrival, etc.

The best way is to concentrate on one manufacturer. This will help ensure that the equipment can talk to each component. It will also ensure that if you have a problem that the manufacturers involved can't point the finger at each and blame the other guy for the problem. Getting caught in the middle of that can be very frustrating and time consuming.

To get the Tack Tick to talk to anything else, you need a Tack Tick NMEA Interface. This is a separate unit that joins the wireless network, and makes NMEA 183 connections to other devices.

thanks jlp. I think my first job will be to get my vhf radio and chart plotter to talk to one another. The vhf has an AIS receiver, and I wants to be able to,display the AIS on the chart plotter screen. Also want the plotter to provide coordinates to the radio.

If I can figure that out, I will work on the wind intranet issue. I found a NMEA wire in the pod for the wind instrument, but not connected. Will that cause issues trying to get the other instruments (plotter and VHF ) from talking to one another?

Appreciate all of the responses.

Actually, from a safety POV, I would concentrate on cleaning up that rat nest of wiring. :snooty: Kind of looks like mine before I cleared it up.

With what you've listed I am having a tough time figuring out what the Garmin N2K bus actually goes to. Follow the drop cables and see where they connect. You may have another depth or speed transducer that displays on the GPS MAP 740 that you are unaware of. As for interfacing the Tacktick it can be done but requires extra boxes. The analog displays from the Datamarine transducers can also be converted but again requires extra boxes. I much prefer to just use N2K products especially if you already have an N2k backbone. If you already have a Garmin ducer you can simply add a GMI-10, GNX-20 or the GMI-20 displays...

How? I was just going to say that converting the Datamarine is impossible? Does Garmin or Raymarine (in my case) have a conversion to the network?

Agree with others, always good to stay with same manufacturer. Tick Tack is probably there since didn't want to pull wires up the mast, but if that could be converted I think.

I am working on it! But trying to figure out what I have, what works, etc....
