The Baofeng, Wouxun and Kenwood radios use the same pin-outs. There are
two plugs on the programming cable: a 2.5mm 3 conductor and a 3.5 3
conductor.
The "shield" or inward-most contact on the 3.5mm plug is "rx" data and
the "ring" on the 2.5mm is the "tx" data. Ground is the "shield" or
inward-most contact on the 2.5mm plug. I cut the USB connector off of
the Baofeng programming cable (which has a counterfeit Prolific chip
that won't work on anything past X86 Windows XP) and wired it to an
in-line 3.5mm 3-conductor (Stereo) socket that works with the Elecraft
programming cable that comes with the KX3. To program the set of
Baofeng 888s handhelds I use for my GMRS license for event management, I
can just unplug the cable from my KX3 and plug it in to the modified
programming cable. Works perfectly.

Hi Don and the group
Could you give us the information on which wires of the Wouxun cable go to
which pins on the DB9 connector so I can use the USB adaptor for my K3 to
program my hand held. I have only 3 computers all using Windows 8.1 and so far
a work around but haven't used it for a month so don't know if it is working
today or next time I need it. Please respond here on the reflector as I know
other people need this information just as I have for almost 2 years. If
possible it would be nice to use the KX3 USB adaptor also.
Thank you and I know your answer will be appreciated.

That "explanation" dances all around the real world situation. The Chinese
have been making cheap counterfeit Prolific and FTDI chips. Both Prolific and FTDI have
produced drivers which detect those counterfeit chips to protect their intellectual
property.
While the counterfeit chips may work fine when used under Windows XP, they will
not work with the newer Windows 7 or 8 drivers.
Yes, there are "workarounds" - turn off Windows updates and load the older drivers which
do not have the detection algorithms. I would prefer not to do that, and I have been burned
several times with the Chinese counterfeit transistors and ICs. I ordered what was supposed to be
2N5739 transistors which are no longer available from reliable manufacturers. I had to throw all
10 of them into the trash because they did not work above the audio range. The SSM2165 used on the
K2 KSB2 board is an obsolete part, but is advertized from Chinese vendors - unfortunately, that
chip does not work, so it is "buyer beware". If you buy counterfeit goods, it is just
like getting a counterfeit $100 bill, it is worthless. Unfortunately, there are vendors who are
listing 'workarounds' in order to sell their counterfeit products rather than 'raising hell' to
stop this proliferation of counterfeit devices.
I cut the USB end off the USB to Wouxun adapter that had the counterfeit chip
in it and will be connecting it to a DB9 connector. I can then connect it to
either a real serial port or to a good USB to serial adapter.

Here is a very good explanation about USB to serial port converters. ( see
below) You pay a higher price but the recommended one works with my Windows 7
PC. I have had no problems connecting older RS232 equipment to my Windows 7 PC.
It works like a champ.
I have no interest in the US Converters but there products work well!

Hi all,
I have had an experience with the Chinese "fake" Prolific USB to serial chips.
A Wouxun VHF/UHF handeld would not work with my Win7 computer because the Prolific
drivers identified the chip as a fake Chinese knockoff. I tried the solutions in the web
as well as the older Prolific drivers with no great success. I even tried the Linux
solutions and was not able to program the handheld (I am not a Linux guru, but I followed
the instructions). Simply, it did not work, and I am not willing to keep a Windows XP
computer going just for these Chinese fake chips. I bought the programming cable in good
faith, but that faith has been destroyed by the Chinese fake chips.
