Wow, what a long thread.
Just installed my new spindle, and checked the board for the 485 chip. Everything seems good, but the one thing I can't find is which USB <-> RS485 board I should buy.
There are plenty of examples of the ones I shouldn't
If I read correctly I want a board that handles the switching of receive to transmit automatically, as the plugin keeps RTS high the whole time - is this correct?
Nearly all the boards I look at seem to have RTS driven switching, so these won't work...?
Slight confused, any guidance on making a purchase in the US greatly appreciated.
