Background
 
For years to program my non-CHIRP radios, I used Windows XP in Parallels on my Intel Mac Mini.
 
Historically I purchased the EZLink USB to K-1 cable to program my original Baofeng UV-5R. It has a FTDI chip and a transparent USB case has two LED indicators to give data traffic information. This cable works well with my Baofeng UV-5R, UV-5Rx3, UV13PRO, TYT-88UV and Pofung BF-T11.
 
Both my Anytone AT-779UV and Radioddity DB20-G came with its own USB to RJ-45 cables with, according to Radioddity, a Prolific chip.
 
Although I continue to use that arrangement, I have upgraded to a 2020 Apple Silicon M1 Mac Mini. The use of Parallels on this Mac does not support XP, so I upgraded to Windows 11, but the ARM architecture, because there is no underlying Intel chip on the Mac.
 
This has caused “upgrade” issues for my programming cables.
 
 

Parts and Tools List
 
The components were purchased from Amazon. You can use alternate sourcing for the parts, but the color-coding might be different.
 
   RJ45 Cat 6 Ethernet Patch Cable
 
   Stereo 3.5mm Jack Connector Audio Cable
 
   Stereo 2.5mm Jack Connector Audio Cable
 
   Electrical tape
 
   Soldering pencil or gun (optional)
 
   Multimeter (optional)

NOTE: If your color coding scheme is different, use a Multimeter to determine the needed wires as follows:

a)  On the RJ-45, determine which wires go to pins 1, 3 and 8 respectively.

b)  On a 3.5mm audio plug to bare wires, determine which bare wire goes to the collar furthest away from the center pin (Rx). Then plug the 3.5mm audio plug into the 3.5mm audio jack to bare wires and use your multimeter to determine which bare wire on the jack matches the Rx wire on the plug.

c)  On a 2.5mm audio plug to bare wires, determine which wire goes to the collar furthest away from the center pin (Gnd). Then plug the 2.5mm audio plug into the 2.5mm audio jack to bare wires and use your multimeter to determine which bare wire on the jack matches the Gnd wire on the plug.

d)  On a 2.5mm audio plug to bare wires, determine which wire goes to the collar in the middle of the plug (Tx). Then plug the 2.5mm audio plug into the 2.5mm audio jack to bare wires and use your multimeter to determine which bare wire on the jack matches the Tx wire on the plug.

Instructions to build adapter:
 
1) Take the Cat 6 Ethernet Patch cable and cut the wire about 12 inches from the RJ-45 connector.
 
2) At the cut end, remove about 1 inch of the outer insulation of the wire, revealing all of the 8 color-coded internal wires.
 
3) We want to focus on 3 of these 8 wires for the RJ-45; the ones connected to Pins 1, 3 and 8.  The color coding on the Amazon purchased Cat 6 cable is: 1=White/Green; 3=White/Orange; and 8=Black.
 
4) On the 3.5mm Jack, we want the Black wire
 
5) On the 2.5mm Jack, we want the Black and White wires.
 
6) Connect the RJ-45 White/Orange wire (RX) to 3.5mm Jack Black wire (Rx Data)
 
7) Connect the RJ-45 Black wire (Gnd) to 2.5mm Jack Black wire (Gnd Data); and
 
8) Connect the RJ-45 White/Green wire (TX) to 2.5mm Jack White wire (TX Data)
 
9) Use your Solder gun/pencil to apply some solder for better connectivity and strength.
 
10) Test the adapter and when you are sure the adapter and USB cable are properly functioning, cut off the remaining unused wires on the RJ-45 cable and the 3.5mm and 2.5mm Jack cables.
 
11) Wrap each of the 3 connected wires apart from each other and use electrical tape to insulate them and fasten the ends of the two cables together.
 
12) Plug the two audio jacks into their appropriate 3.5mm and 2.5mm plugs on the K-1 end of the USB cable and use electrical tape to hold them together for the proper spacing.
 
 

 
Parts Reference
-  The FTDI Driver was acquired directly from FTDI Chip
 
 
The adapter and FTDI USB cable now work perfectly to program both my Anytone AT-779UV and my Radioddity DB20-G in Windows 11 ARM.
