Hello to everyone.
We use Garmin, Lowrance brand fishfinders with cable connection on our boats. However, I haven't come across a project about converting them to wireless.
Some use the NMEA0183, some use the NMEA2000 protocol.
My thought is this;
To be able to transfer data between Transducer and Monitor with Lora.
Is there an article you can refer to for this? Or have knowledge?
For example, when I connect the monitor and transducer to the arduino, would it be sufficient to just transmit the data I receive between each other? Or should I interpret them with the relevant libraries and then pass them on?
have a look at NMEA2000 protocol and NMEA0183 library
how far apart are the transducer and monitor? what are the environmental conditions?
possibly you could replace the Monitor with Arduino microcontrollers - what extra facilities would you gain?
Thanks for the answer
I plan to receive data from a distance with the Lora module. This will be on the water and I believe Lora will achieve this without any problems.
The product I want to use is "Lowrance Hook2 4x" or "Garmin Striker Vivid 5VC".
I plan to connect the sonar converter to Arduino and transmit the data I read to Lora.
I intend to receive data from anywhere with the Monitor, without being dependent on the sonar transducer.
I have not used one, but I do count on being able to grab a set off some shelf and easily replace any cabled serial communications setup I might want to, without code or any real fuss at all.
Which as I say may or may not be what I hope to find the day I need it: a pair of modules that can literally be placed at each end of what was formerly a cable between two points.
Of course it's way less fun than doing it any number of other ways.
Wow, if it's really easy as you say (snap on both wires and start receiving data), I'd say it's a really great module.
You are very lucky to have the product in hand.
Now I have to achieve this in a different way.
So any help would be appreciated.
As far as I understand the Garmin Striker Vivid 5cv model is NMEA0183. The sonar mirror comes with a 4-pin cable. The monitor also has 4 pins for mirror connection and has a different input for power supply. How can I communicate these two remotely? I thought with Arduino, RS232 TTL converter and Lora. But if there's an easier way, I'd be very grateful..
This is what I am talking about, 1000 words. I repeat, I have not done this; I only hope if I ever need to do it will be as simple,e as plunking down the money for the wireless modem set.
You can have fun making your own wireless modem out of parts laying around the home (mine anyways) or you can buy some wireless modems.
Sorry if it looks like I drew the diagram using my finger sitting under the umbrella at the beach. There's a reason that's what it looks like.
But the thing in the big bold box is a 1. converter to get the data in and out of an 2. Srduino which then uses some kind of 3. RF module and code to transmit/receive the data with another identical setup.
It's down to what kind of fun you want to have and I suppose where you like to spend time and/or money.
As far as I know, LoRa is a packetised comms system and would need quite a lot of protocol to transmit serial data transparently. As I understand it you are seeking a "wireless wire" that just replaces the data cable. That appears to be what the Zulu product offers.
Thanks for the answers.
As far as I saw the product specified in the Zulu model, yes, it is the product I was looking for. but it appears to be discontinued. or if there is a product that can be used instead of Zulu, I would definitely like to try it. Otherwise, choosing the hard way is not my choice, it's my obligation
What distance do you need to communicate over? There's a class of devices called "wireless serial modems" or "wireless serial servers" whose job is to take an RS232 signal and transmit it over a radio link to another device. The specific device would depend on what features you need. Here's an example: https://www.digikey.com/en/products/detail/aim-dynamics/USR-W610/13530863
Depending on how far you need to transmit, it may be simple to DIY, or not.
Thank you very much, I will look into it. It appears as LoraSerial, I hope I can find products close to it, because it is very difficult to procure this product..
