Re: QCX+ CAT control with ready made FTDI cable

Very goood question,
checked with the scope and looking carefully it should be what is needed.
Still I wasn't completely convinced but in the end it works, either HRD and WSJT-X are able to see and use the radio, no mod except the sw handshake setting that triggered the occasional senior moment.
YMMV of course.
The interface transmits on the tip of the JACK PLUG, and this is what QCC+ expects, the signals shold be crossed to talk.
See the manual, probably what fooled me was the picture on the left(section 3.7.7 page 101), albeit correct it lists the connection from top to bottom but the top most listed is the middle in the JACK (either) my suggestion is to rearrange the listing order of the wire, should be even easier.
Next will be the gps connection.

I looked up that wire on Amazon and found https://www.amazon.de/dp/B07JBJHSTL/
The pinout is exactly the opposite of what's listed in the QCX+ manual. Did you have to make any changes, did it just work or did I miss something?
Cable: Sleeve ground / Ring RxD / Tip TxD
