Success!
I twigged to the solution from a comment Rick made. I had been removing the RS-485 chip next to the capacitor instead of the RJ-45 connector. Also I believe that I pooched the second v2 Tx/Rx that I made as I have been unable to "unbridge" the two caps directly below the pic.
I now have a v2 Tx talking to a v1 receiver.
Thank you all for your patience. I'm really glad that I didn't have to get another Lynx to see if it was the problem as the weather in Brandon Manitoba right now is -20 C which is -4 F, but with the wind-chill feels like -36 F.
Now I just have to venture out to setup this last controller...
Thank you RJ, Rick, smartcontrols, and n1ist for all your time and patience!
Best regards,
Glen
