    Electromagnetic Interference problem

    An Optical Fiber cable converter is around $800 for the entire setup for my particular application. Being as the (CAT5) data cable has already been run in the conduit with the power wires, I am thinking of simply replacing the UTP (Unshielded Twisted Pair) CAT5 cable with a shielded version of...

    Electromagnetic Interference problem

    Our data translation hardware is grounded next to the motor that we are measuring the vibration from. When we move the computer (Laptop for this application) away from the motor and begin the vibration analysis everything works as it should. The CAT5 cable that is run into the control room...

    Electromagnetic Interference problem

    I have thought about going and buying a hundred feet of CAT6 just to ensure that it isn't the Ethernet cable causing problems with my system. Could anyone explain to me how a USB to Ethernet converter works? Could I use a USB to Ethernet converter on one end and just run the cat5 straight into...

    Electromagnetic Interference problem

    I have tried using battery power on the laptop only (holding it in my hands) and the vibration analysis program still freezes. I thought it might be a ground loop issue so I installed a UPS powered HP PC out there a week ago and still the same problem exists... Which leads me back to the USB...

    Electromagnetic Interference problem

    Can anyone think of anything else (other than EMI from the soft starter) that could be causing this issue with the vibration analysis program? The program freezes when the soft starter kicks on but after I close out of the program and open it back up (with the motor still running) if functions...

    Electromagnetic Interference problem

    The converter needs to be in the same room as the computer with the vibration analysis software on it. If I use the copper tape I linked in the post above, I assume I should ground it to something outside of the control panel where the soft starter is located. I have attached a picture of what...

    Electromagnetic Interference problem

    We cannot move the computer outside of the control room. Would this be an option for wrapping around the USB over CAT5 Converter? Link Thanks for all the help guys.

    Electromagnetic Interference problem

    We tried bringing the USB cable outside of the control room (effectively increasing the distance) to see if that had any effect on the EMI and the vibration analysis software worked great. It's only when the converter is inside of the control room that this problem occurs. I have looked...

    Electromagnetic Interference problem

    I should have been more specific... I am measuring data from a motor 50 feet away. I am using a USB of CAT5 ethernet converter to get around the USB length limitations (16.4 ft) The data translation module is powered by the USB port on the PC (Which goes over the CAT5 until right inside the...

    Electromagnetic Interference problem

    I am performing vibration analysis on a motor that is around 50 feet away from the control panel. The output of the data translation module I am using has a USB output, therefore I had to install A USB over CAT5 converter to run it out to the control panel (since the limitation on USB is 16.4...
