I have a Uniden BCT15 scanner that I previously programed using the serial cable and the bctool software. My new computer does not have a serial port, so I purchased the Uniden USB PC Interface Cable, USB-1. I downloaded & installed the Prolific PL2303 chipset driver, connected the USB-1 cable which was recognized as a "com port". I connected the cable to the BCT15 scanner and opened the bctool software. I clicked on "connect to scanner" and the software said it is connected but the scanner does not connect and I cannot read from the scanner. Any help that I can get is greatly appreciated.
