Finally managed to get the 14.6.0 software talking to my S-drive 200Amp controller! using the Serial converter module I posted in a link above and mods as per above posts.
I did this by removing the 33k(47k) resistor altogether.
The process I used is as follows:
1 - Without anything connected to the 4-pin Molex plug on the controller, I turned on the controller, and checked the DC voltages available on pins 3 and 4 with a multimeter
2 - confirmed with a TTL logic probe that there were data pulses on those pins.
My reasoning was that because there is 5 volts supplied by the controller on pin 4 of the molex, when the controller is 'On' then there is no need for further voltage to be supplied via the resistor from the USB of the PC.
NOTE: I have only tried this on the S-drive 200Amp controller.
A huge thanks to Woody and Burgerman for providing this forum and those who share their knowledge and experiences here.

Remembering that the connection convention is RX < TX & TX > RX ...
With or without diode?
Direct cable?
NOTE:- THE CONTROLLER MUST BE SWITCHED ON FOR PROGRAMMING & YOU MUST TELL THE SOFTWARE THE COM PORT NUMBER ASSIGNED TO YOUR USB LEAD.

To turn on the controller connect 24V+ to pin 5 of the 14 pin socket.
You will need the INDUSTRIAL Software to program the Solo.
