Use MA3d and fixtures on one ethernet port

  • Hi joseflekardal,
    yes, that´s possible.
    The dot2 is able to communicate with different ethernet protocols at the same time via the same ethercon port.
    If your communtication towards your rig is done via ArtNet or sACN, the options you´ve found in setup/network protocols.

    The communication towards your dot2 3D is done via IPv6 and dot2 protocol, so you don´t need any options- it just connects.
    So if you put a network switch inbetween, all should normaly work without any further setup work.

  • Hello. I will connect to the topic. I have a console connected to the router. I have a 3d dot2 running on my laptop, and connect with a laptop via a wi-fi. Everything works well with a small show file. When I have a larger file volume, the console sends data to the network, dot23d - "working", after a dozen or so seconds the console again sends data to the dot23d network again "working", and so on and on. What are the minimum requirements for wi-fi (bandwidth) networks envisaged for cooperation with dot2? I know that I certainly have to change the router faster. :)

  • Very hard to impossible to answer this.
    The point is, that WiFi doesn´t offer a stable constant connection.
    Also nobody ever stated that WiFi is a "realtime" data transmission.
    Means that it might work (as you say) for smaller shows, but as soon as the ammount of data exceeds a certain level, it doesn´t work.
    What influences this as well is, that maybe some waiter with an alloy plate serves drinks and a refection or and interrupion appears in WiFi...
    What I want to say is, with a cable connection you don´t have all the "maybees" inbetween the transmitting device and the receiving one.

    The dot2 3D is handled in the network structure as a console- it gets the full amount of show data whenever the system thinks it´s necessary.
    If the receiving station cant reply back "yes, I have received all the data you wanted to send me" in time,
    what should the transmitter do? Is it a fault from the receiver, is it a problem on the way to the receiver and so on...

    That´s why we always state not to use WiFi (inbetween consoles or similar rated stations in a network)- if it might work or not,
    there will come the moment, when it will not work- be sure.

    Long speak, short sense: No serious person will be able to tell you where the limit is, between working and darkness where there should be light... ;)

  • You're right. The cable is a more reliable connection. However, the console gives you options such as wi-fi connections, so I sometimes use it. Why? Because it is straight and fast. And this is enough for me, after all (except for small exceptions), it only serves to visualize, and the clou of the case takes place on the stage. Wi-fi does not give a stable and reliable connection, I do not discuss it, after all we can see that even professional players on the stage lighting market offer lamps with built-in WDMX, and designers distribute networks through objects using this technology. Risk - but this is probably the future - without cables.
    I understand that it is difficult to answer my question, because it has a lot of unknowns. I rent some routers and check it in configuration - my
    show - router - my laptop.
    Thank you for your answer. Regards. :)

  • No guy, sorry,
    we use professional Lumen Radio wireless dmx transmitters sucessfully for years, they are really great. They operate in 2,4 Gb, because this is not licensed. But wireless free times with today's frequency technologies comes out very fast. At many venues transmission troubles occures not because of wifi speed, you are fixed on. Huge amount of other waves in the air all around causes mush. Coexistence all of these signals is at its limit. Try to find wifis on the city square. Neverending amount, all of them with only 12 channels.

    Chinese wireless fixtures? They respect no standards about transmission volume, have droppings, it is completly not stable solution making more mush in the air. I tried some.

    What is more, tens of our wireless microphones both frequency range C and G have more and more troubles to find a free frequency (in cities). Some part of the free band have been sold for LTE mobile networks, it is much narrow now in our country. Manufacturers consider about new sentence in manuals: We do not guarantee the function. Really. And never try to use wifi wireless microphones. The reason is the same. Terrible troubles.

    If you want play at home, use wifi and dream about wireless world, why not, it looks cool, but always use wires for the serious jobs, otherwise you risk all. And we work for money :)


  • You're right. But not all. Show me an artist who is singing to a microphone on a cable today? A guitarist who can play wireles, he attaches to his 5m cable. We have been using wireless microphones successfully for many years. And I can not imagine an actor who plays with a microphone on a cable, sorry. Of course, LTE occupies some bandwidth, but new wireless systems - digital systems have long been added. Wireless systems have interference, cable too. You probably use a mobile phone, you do not always have a range, but you will not give it up for a wired telephone, just because sometimes you have no coverage. Controlling the console with a smartphone also sometimes loses something in time, but I do not intend to give it up in favor of running a few dozen meters to the console to put out one spotlight.
    But as a matter of fact, my question was about something completely different.
    I do not want to control the light through wi-fi. I connect a visualizer running on a laptop, with a console, using wi-fi. For me, there is no problem with the stability of the connection, after all it is max 1-2m. And there is no problem with "controlling" the DMX data visualizer. I have less than one uniwerse busy. The "problem" appeared only at the beginning when the console sends the show data, data containing all 3d elements (also mine, not very optimized), etc.
    I have a router working in the G standard (this was provided to us along with the console). So it is not a "demon" of speed. So
    I asked a question, counting on a hint, some small suggestion, is it worth investing in a more expensive router (n or ac type), does not make
    sense, because the transmission speed is ok, only there was another "problem". And that's all.
    And just as I understood what Michael wrote. The console sends data to the network, dot23d receives them. The console does not get the answer that the program received all the data, because dot23d is busy processing the received data, so it sends them again, and so on and on.
    So maybe if the question asked by the console whether you received all the data, dot23d could answer - "wait, I'm still working on this data, do not be so nervous", our problem (in quotes), it would cease to be a problem. But I do not know it, and I do not know how it works. ?(
    cheers :)

  • Hi nasula,
    it seems to me, that a few things are mixed up in this discussion.

    I don´t know much about the stability of wireless microphone transmissions or wireless DMX and if these transmissions are reliable or not, that´s not our business.
    I worked on quite a few jobs where we had to use wireless DMX products because of geographic issues and with the right antennas, transceivers aso. it worked fine.
    If it wouldn´t, what would happen?- just a few lights that are not doing what I wanted them to do.
    Looks maybe not as the customer or artist expected, but nobody would have died.

    We are talking about transmissions of a DMX signal that has a speed which is, compared to most ethernet protocols, absolutely boring.
    And: most fixtures do not send back anything that would be of my interest during the show.

    We wanted to talk about stations in a network, that could perform only 100% when they are connected as stable as possible.
    We are also talking about a bi- directional communication and as I wrote in my first answer- the 3D visualizer is handled like a console in MA networks.
    We are also talking about the brain of your lighting system, not just a few fixtures that might get stuck or cannot do as they should- if the brain stops working,
    all of the body becomes just a piece of heavy mass, hanging around.

    I have read, that you´re only having one universe of DMX and the distance inbetween the transmitter and receiver is short, but as you can see, it even does not work reliable over 2 meters!

    In your case and until now, nothing to worry about as it´s only the visualisation that doesn´t work.
    But what if a busy or not correctly responding station in your (little) network setup makes your console stop working?
    This can happen, so why to risk it?

    I could bore you now with a lot of details about what happens, what might and why we do things like we do at MA, but I don´t.

    In your case (I know, I know) it´s a little network but it´s not only a visulizer that doesn´t work propperly,
    it´s a fully station in your network that fails and might influence other stations in the system to do their job correctly.

    Or to say it simple: if you want to be professional, please do not do it. (or work for the handfull of companys worldwide that have the knowledge and equipment)
    Just not.
    Even if it´s only half of a fixture and the distance is 1 meter.
    Btw, why in the world do you that for a 2 m distance between your console and your 3D ???
