Re: [chirp_users] chirp_users Digest, Vol 69, Issue 20
Yes you need a ground reference connection. Join the Data TX and RX together onto the data pin and it works.
I made my own cable for the VX-5 and it works.

It seems like VX-7R uses one pin for data and it is bidirectional. If that is the case then you should add some more components to convert bidirectional single pin to standard RX/TX serial connection.

Hi Bob,
Thanks for that advice. I had started to think that I was going to try that as I'd seen a number of photos of the CP2102 with the RX and TX pins jumpered together and I read this PDF file too.

I should have the various bits and pieces here by the weekend if the Ebay traders do their stuff and I'll give it a go.
