    Default max Length btw USB and Teensy to operate (Vixen data flow)

    Hi,

    Does anybody know the max length for an USB cable connected on a Vixen Laptop (USB 2.0) and a Teensy controler.
    Is there a limit in communication range, so at what range do VIXEN don't get all data out to the controler and we got mixups in the light display?

    Greetings
    Thomas

    I think the USB 2.0 specification distance is 5 meters. So I bought a 65 foot (20 M) USB extender from Monoprice last year. I connected my Arduino MEGA without any issues. They make a longer one (82 feet) as well.

    Keep in mind that Vixen is an application running on a computer and is not in control of the computers ability to create a clean USB signal.

    Different computers use different chips to implement the USB interfaces. The spec is 5M (16'). You can go longer if you have a well designed interface and good cable. You can also insert USB hubs at strategic locations to get a bit more distance.

    Ok, thx for the details.
    It should be a 10m distance. Therefore I think i will run the controler next to the computer.

    Remember, if going a longer distance in USB, you may look at the extension cables. But pick one that has a repeater built in. This will keep the signal from degrading.

    even better is an active USB over cat5 converter pair. They're similar price to USB booster/repeater cables, but you can make the cat5 yourself and make it any length you like.
