Tacktick to NMEA2WiFI with Garmin

Post by olly_love » Fri Jan 13, 2023 2:55 pm

Hi We have a Tacktick system running through the T122 interface (NMEA)
with this we also have a Garmin 557 plotter which can send data to the tacktick and recieve,

We want to be able to use the laptop or phone with Wi-FI to send data to the tackticks via the NMEA2 WIFI but we seem to not get anything through?

Im assuming that there is a data conflict between the Garmin Plotter and the Data from the Phone/Laptop 9 prob RMB sentence.

Thought please?

Also any help with wiring would be great

Hello

I have no experience with the T122. I couldn't not get the user manual to know how it's wifi interface works and if it can communicate with our multiplexeres through WIFI.

What app will you use in the laptop to send data to the multiplexer? I am assuming that you want to connect the laptop (or phone) to the T122 through the multiplexer. And using no wires, only wifi. This is strange to me. If the T122 has a wifi interface why to place the multiplexer in between?

I am sorry but I need more information.

Regards, Luis

Hi the Tacktick system runs on its on wireless network and is not accessible to other devices the T122 is the Tacktick to NMEA box as per the diagram i have shown,

The issue we are having is that we can receive data over the NMEA2Wifi box but not send this?

We are running Iregatta on the phone and Expedition on the laptop.
We also have a USB connection to the laptop but have the same issue of not recieving on the instruments hence i feel i may need the NMEA4Wifi to provide more inputs and outputs and also filtering

Hi,

Thank you for your explanation. Still if you can send a URL for the manual it would useful. As far as I could understand you cannot communicate between the T112 and the multiplexer through wifi. Only using the wired ports on the diagram.

So you would dedicate the nmea0183 output of the T112 to connect to one of the input ports of Nmea2Wifi (I don't know how you can set the baud rate on the T112). Then you would connect the output P3 of the multiplexer to the Nmea 2 input port of the T112. That is for the multiplexer to the T112 connection.

For the laptop to the multiplexer communication you would use wifi. In the multiplexer to laptop direction the best is to use UDP and on the other direction (laptop to multiplexer) you could use TCP.

Have you a Nmea2Wifi? If you have sensors that you need to add to your system there is only 1 input port left (the other is receiving data from the T112. The Nmea4Wifi has more input ports and as you say filtering.

Hope that helps, Luis

Hi the manual is here

http://www.tacktick.net/pdf/tacktick-Hu ... ter_ug.pdf

Our issue is that we cannot seem to get the information to send back from the multiplexer to the system or it gets over written by the plotter signals

I have got everything plugged in on a test rig now

When on simulate I can get data to the instruments and all works well

The issue is that the iRegatta app is outputting the attached sentence which none of the systems can read?

Is this something that the multiplexer isn’t reading right?

Hello,

I am sorry. I did not get time to read the manual you sent. Your system is totally strange to me. I will try to read and answer. Do you mean that during 20 seconds you only get that sentence? What would you expect? Could you copy and paste into a txt file the text that appears in the debug window? A picture does not help. For example I would like to check if the checksum is OK.

Regards, Luis

Olly, if I can add something.
RMB is a waypoint message, so are you trying to send a waypoint or route from IRegatta?
The multiplexer IS seeing this message, as you caught it in the debug, and it will send it from UDP to any output provided you select the appropriate UDP>xxx button.

Depending on what program / instrument is ‘receiving’ the message it may or may not be able to interpret and display the RMB message.

Are you trying to see the waypoint data on the TackTic multi display ? .

Follow up:
I think I now see from earlier posts that you are trying to send the Multiplexed output from the NMEA2 ("P3" =Pins A3/B3) to a TackTick NMEA wireless interface. To do this you presumably have already set the UDP>P3 . But you need to know the Baud rate to use: (and connections).

The Manual for the Tactic is spectacularly uninformative on Baud rates needed, so the simplest approach is probably just to try various Baud rates:
I would try 4800 first and see if the Tactick multi display "now" recognises the waypoints.
If not, change to 9600 and repeat!

There are also some notes on the website on NMEA wiring options to use (and to avoid) that Luis wrote to assist connection problems:

When you do get connection, please post here the Baud rate needed to assist others with similar TackTic Baud problems!
