I think there is a short in my Pfaff 7570 power switch. Sometimes it will not come on at all. Other times when I hold the switch in, it stays on, but when I let it go, it goes off. Sometimes it will sew for a while and then go off until I touch and hold the switch. How can I fix this? Thanks, Yvonne

It sounds like you have it configured properly if you have the little machine and computer appearing on the display screen. I had this problem too in the beginning, file assistant doesn't use the files for the 7570 its only for some of the newer machines, use Vip customize to send the design to the machine from the file drop down menu. Hope this helps.

I have Windows Vista; I also had a similar problem; found out that I could only use the usb port on my computer exclusively for sewing as the driver software seems to conflict;
Also, having said that, go to Pfaff.com & download the free driver upgrade and see if that will get you started good luck deb

I bought a 25 pin female RS-232 to USB cable from a computer repair store. It works great. You will have to install the software that comes with it so the computer will know that it is a serial port.

SOURCE: connect PfaFF Creative 7570 to a PC

The software you need to connect the Pfaff 7570 to the PC and to create your designs is called PC-Designer version 2.2 from Pfaff. You may be able to find a used copy. The software should come with a dongle (special cable) for connecting the machine to the PC. Make sure you have this piece because it will not work with an ordinary cable. Depending on what type of port you have on the PC to connect to, you may also need an adapter since the dongle has an old style connector on the end going to the PC. If you are going to create your own designs, you will also need a storage card which inserts into the machine that you send the designs to. Pfaff makes one, called the creative card. I have also used a generic card meant for the pfaff; the generic card is less expensive and has a greater capacity. You can find many designs online either free or for sale to send from PC to Pfaff as well.
