I had a similar problem with K3 and SteppIR SDA-100 controller. Experimenting
with the order may solve the problem, it's worth a try.
I found that the how I added the devices, the order apparently made a
difference. Try a fresh start the computer on, next turn on the radio and
finally the SteppIR controller. That worked for me but I have not had the
problem repeat so it may have been just a temporary software issue.

I built my serial cable for the K2 to talk to my SteppIR controller from the
Elecraft manual. Works just fine. It also talks to my computer for HRD, N1MM
etc. So I decided to work on having the two interfaces work together like they
did with my IC 746 Pro. However, building a Y cable doesn't seem to be working
out the way I want! Each device works fine when I have it plugged into the Y
cable by itself but when I plug in both at the same time, One or the other will
freeze up. I am simply using pins 2, 3 and 5 from the K2 serial port wired
straight through to the female DB 9s at the device end and have 7 and 8
jumpered at the external device end. What am I doing wrong?
My KPA500 arrives on Monday so I'd like to get this resolved before my next
project!
