Joe, you're right of course - and thank you. I have no clue why I typed DTR! Google sources did indeed say RXD (received data, pin 2) and that is in fact how I wired the cable. I guess I was looking at my hand drawn schematic notes and my eyes got a little dyslexic.
Also, thanks to you and others for mentioning that pins 7 and 9 need to be shorted (as shown in the schematic you sent). I did that, and - voila! Everything's working now - SteppIR, MixW, N1MM+. (the latter programs one at a time, or course). Thanks, everyone. 73 Ray K2HYD On Wed, Aug 14, 2019 at 10:44 PM Joe Subich, W4TV <li...@subich.com> wrote: > > > I made up a Y cable to interconnect K3, SteppIR controller and > > computer.
