I have two VX-510s that I am trying to program, I have the software and I purchased a programming cable from ebay. When I tried to program for the first time the programming cable that I bought would not fit in the mic jack, as the software says. So I went to radio shack and bought an adapter to go from 3.5mm jack to 2.5mm jack and so far everything is fitting in the appropriate inputs. I hook it up to my computer and follow the instructions to read the radio and it doesn't read. So I tried to just program one channel, and when I try to write it to the radio I get an error saying "Problem detected with connection to interface box. Transfer aborted." Am I doing something wrong? Any help would be greatly appreciated.
