Dear Mal, LF Group,...>Does anyone know of a QRS prog that uses the USB port on a computer instead of the Serial or Parallel ports de mal/g3kev...>More to the point, how to connect the other end of the USB cable to the transmitter, given that it only contains fixed 0, +5V power supply connections and a differential pair carrying high-speed bi-directional data. The usual solution is to use one of the inexpensive USB - RS232 converters. The one in use here takes the form of a cable with USB plug on one end and D9 plug on the other, containing the interface circuit. It seems to work fine. Cheers, Jim Moritz 73 de M0BMU |
