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.

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!
