John thanks for the suggestion. Having a built in converter is the way to go. However I am a little confused. If this cable will work for programming and data transfer... Will my OPC-478U do the same? Work for both applications?
Now that I have a working D RATS program using the internet, I am wanting to set up a RF connection. Does anyone know of a USB version of the OPC-1529 data cable? If not, what serial to usb converter would you recommend?? I am running Windows 8.1. Looking
for recommendations from those that know the converter will work.
