I am trying to connect a newer computer (w/usb ports) to my toyota 850 embroidery machine. I bought a usb to serial adapter to use with the pre-existing serial cable and thought that would work but it did not. I called Datastitch today and they indicated that this seems to be a common problem encountered when updating to a newer computer. They suggested a BAFO (brand) cable. After looking at numerous web pages, I think I need the BF-810 cable...does anyone know specifically which one I may need? Also, if you have any other suggestions on adapters and/or cables that may work I would appreciate the help. Thanks!
