All,

Turns out I had a bad RS232 cable. By process of elimination worked my way back through the extension cable (fine) then USB to RS232 cable (fine) then :

Replaced the RS232 cable in the back of the unit and, bingo! Unit detected.

Just had to install a new version of Mconfig exe, and I am now up and away.

Whew 🤣. Was feeling pretty worried there..
