One thing that might help others who are having issues with these units:

Which pins did power go to?

Which pins do you see RX (and maybe TX) data on?

Which cables went where (and their pinout) to interconnect this or that? 

What software are you using?

Yes, One could make some pretty quick guesses at most of this. It’s often a quick guess gone wrong that messes people up …
