    Hi all,

    i know Dsnake can go through dmx cable(xlr 110ohm), also dmx can go through cat5 via rj45 plug.

    Now, is the Qu32 to DSnake protocol using all cat5 wires?
    I mean, if i have only 1 cable to run Dsnake and dmx from my office to the stage…possible?
    But maybe all cat5 pairs are already buzy with DSnake…

    Thx.

    “i know Dsnake can go through dmx cable”

    I’m pretty sure it can’t.

    I think you need another cable

    I guess in theory 100mb/s ethernet only uses 4 of the wires in an Ethernet cable (though impedance seems to be less than half dmx), and a 3 pin dmx cable has 3 wires, so you could probably craft some wonky dmx to ethernet adapter for the unused wires… but the impedance mismatch will cause problems, same reason as why mic cables shouldn’t be used for dmx. 4-pins of Ethernet to a 5-pin dmx adapter is an even worse idea, it would leave no spare wires for the dmx signal (and there isn’t any reason to use a dmx cable for ethernet to begin with; A&H definitely doesn’t have support for something crazy like that).

    To be honest, you should not try making any crazy adapter. The right way to use a shared ethernet cable for carrying both would be getting a box or two like https://www.amazon.com/70405-Ethernet-Lighting-Controller-Interface/dp/B072XY2PGV/ref=pd_lpo_vtph_147_tr_t_2?_encoding=UTF8&psc=1&refRID=01VAPWQMMGWHV8VJ4GR5 that converts the dmx signal into a protocol that is properly wrapped by in Ethernet packets, then have network switches at either end of your ethernet cable.

    Oh, seems I did a mistake by saying something.
    I think I had some confusion on wires/cables and protocols.
    I did check!

    Thx guys for your responses …and sorry for that.

    but anyway… if you are using 100MBit only you can use the remaining wires for DMX
    it works, but it’s not foolproof

    From what I’ve always found CAT cable is 110ohm. Someone can correct me if that’s wrong. That said I know dmx will work on CAT. I’ve heard of contractors using it on permanent installs. I haven’t.

    To my knowledge and again I might be wrong , in CAT cable orange/white-orange and brown/white-brown are not used unless there is POE which runs on the orange pair. Only the middle 4 wires are used. So in theory you could do what the O/P has requested. My thought though is that CAT cable is cheap enough why not just run two to keep from fabricating and adapter.

    huu!?

    So, can I make myself this wiring by taking cables, wich are not use by DSnake protocol?
    Wich one?

    get it, thx GCumbee!

    blue/white blue and brown/white brown are unused on ‘Ethernet LAN Standards’ chart
    Not in GigaBite, wich requires 4 pairs of course, it’s ok.

    I will try this on a tiny box/pc cable first then why not the long one.

    Want to heard about this or not guys? I can give ou some news soon…
