I'm trying to use Butel ARC433 programming software. I have the Radio Shack catalog #20-047 cable, and I have the drivers from that cable installed on my PC. I used the same cable on my Pro-96 and Pro-163 with no scanner detection problem. However, when I use ARC433 and connect the cable to the back of the scanner (PC/IF) the scanner will not recognize the cable. I tried auto-detect on the 433 software, but I keep getting an error message, saying software cannot detect scanner. Please help! Thanks.
