BC296D

I don't know if anyone can identify with my problem, but I have a used BC296D handheld scanner. The manual is very difficult, along with the software, to understand and doesnt make sense ! I have been having a terrible time with PC control., getting a continuoes "communication error. check the Bc250 or 296 SS remote" Someone had suggested keeping at 19200, but not the cause. I contacted Uniden support and they recommended the USB-1. After researching their own site, it says this cannot be used with my model, and suggested the prolific PL 2303 (serial to usb) that I have, through radio shack. More research said that a new driver may be the problem, but still nothing. Does anyone have any situation like this ? Thanks
