There have been errors in several ads that say the cable fits the BC296D when it does not. I have seen numerous reports where people who ordered the cables say they do not fit. I have a BC296D cable and it does not fit the BCD396T, BCD996T, BCD396XT, or BCD996XT. The plug is closer to being a square shape than the other Uniden RS232 serial cables. Take this ad for example: Amazon.com: USB to RS232 Mini 4P Serial Adapter Cable for Uniden Bearcat BC250D BC296D UBC3300XLT Scanner PC Programming Cable FTDI Chip : Electronics Stated in this ad:The other ad link picture, either a bad picture or they used the wrong cable for the ad.
Better look at the connector, I recall doing a 296d years ago and I didn't have to use a special cable that I didn't already have.
All had to use was the serial-usb adapter and the serial cable that came with the 396T/396XT's. I used the cable for the 396's and I also recently did a 796D and used just the serial-usb adapter cable only to plug into that 796D.
This ad even mentions 396.
tvenger is again correct.I have a BC296D cable and it does not fit the BCD396T, BCD996T, BCD396XT, or BCD996XT.
Older USB cables are not compatible with Windows 10. In fact, many of the older USB to serial adapters aren't compatible. I had to get a newer USB to serial adapter to use with the cable that came with the radio to get ProScan to talk to my BCT15, 996T, 996XT, 396T and 396XT. This might be the answer to get the computer to talk to your radio.
That looks exactly like the plug on my BC296D cable.This is a close up of the scanner end for the BC296D scanner cable shown in that scanner ad:
The BC796D has a DB9 female connector on the rear for programming. The digital card gizmo is behind the cover labelled EXPANSION SLOT. If your computer does not have a serial port, you will need a USB to serial adapter cable. This is the one I use for programming my BC796D scanners: Insignia™ 1.3' USB-to-RS-232 (DB9) PDA/Serial Adapter Cable Black NS-PU99501 - Best Buy It will connect directly from the USB port on your computer to the DB9 connector on the rear of the scanner. You can use a short DB9 extension cable if desired. Please let me know if you have any questions about the scanner. I use Butel ARC250 Basic software to do my programming. With the software, I would be happy to do a file for you. You can try this to check if your present cable works: In your scanner, press MENU. Using the CHAN/FREQ knob, scroll to SYSTEM OPTION and press E. Scroll to PC CONTROL and press E. Select 57600 bps and press E. Press SCAN to exit the menus. With the scanner connected to your computer, go the tab in the ARC250 software with the scanner model (BC250D, BC296D, BC785D, or BC796D) and click on RS232 Communication and Scanner Model Setup. Select a Baudrate of 57600 and the scanner model of BC796D. If you click on AutoDetect, the software will find the computer port for you. Click on OK to exit RS232 Setup.I bought a cable from a dealer that allegedly oughta work. My scanner's a -BC796D- with the APCO P25-II gizmo in it.
I tried the reputable scanner-programming progs, downloaded from reputable sources, and none would talk to it through the cable. My PC is a common Win10 machine, and I can't be sure if it's a PC, cable, or scanner issue.
