It is a standard USB-1 cable modified to replace the small Uniden serial plug with a DB-9 so the standard USB-1 driver is used.Rich,
I have seen your videos, checked the pictures, read your posts AND have googled for the Driver for the rear Serial Port on the BCT15X and BCD996P2 to USB, and can't find it. All I can find is the front port driver to USB. I need the Serial to USB so as I can run my scanners from the rear to ProScan, yes like yours. Not from the front with cables hanging. Yes, I have the Serial to USB cables purchased already but my PC is only recognizing the scanners from the front port.
The Green wire from the USB-1 goes to Pin 2 on the DB-9F, the Red to Pin 3 and the black to Pin 5.
