The Conversion Software and the PC communicate with the Quantum® XL-6000 through a special serial port cable called a Null Modem Cable, (Singer Part # 270-10D1-20206 for 6-foot cable, Part # 270-10D1-20210 for 10-foot cable). This special cable is a 9-pin cable with both a male and female end, one for the PC and one for the sewing machine. The wiring in a Null Modem cable is configured in a way to allow communication to flow both ways between the two devices, the PC and the machine. A straight serial port cable will not allow the information to flow back and forth. However, a Null Modem Adapter may be added to a straight serial port cable, creating the same effect.
If you have windows 7 follow this. Jenny Q.My computer only has USB ports. Can you recommend a Serial (nine pin) to USB converter cable that will work with the Professional Sew Ware™ 2.00a?A.We have found that the PSW works best on newer computers when the USB serial adapter cable has not only compatible drivers for the Windows operating system but also a FTDI chip. We have found this FTDI chip in the cable which is listed below: CUSB-232A available from Computerplug.com and Cablesalesusa.com. Any USB to serial adapter with an FTDI chip will work. These cables will work for Windows XP, VISTA, and 7. ___________________________________ I forgot to add.....I have the usb cable and port all set up....I think my problem is with the conversion tool software running on Windows 7. Is there an update, patch, or something?
