randyb 1 Posted February 15, 2009 Sorry if this has been covered but i want to switch from USB to 9 pin port? Can somebody explain, (step by step) how to hook up this way.And the correct cable to use? When i plug it in nothing happens.I have a feeling i am not getting the drivers installed correctly? My MH721 works pretty well with the USB but it does stop sometimes on really big cuts. From what i read 9-pin is the way to go? Also i have a 9-pin to USB cable.Is this a good way to connect? or not so much? Share this post Link to post Share on other sites
