The SteppIR "S26" cable will result in a doubly loaded "serial in"
line (two drivers connected to the K2/K3/K3S RxD line resulting in
no data to the K2/K3/K3s) when used with a standard "all 9" DB9 Y
cable.
The schematic for the SteppIR "Y" cable that I provided to K2HYD is
also available in the SteppIR groups.io files section and works
directly with SteppIR controllers and the K2, K3, K3S without any
other cables.
BTW, your "FT947" cable is labeled incorrectly - it is FT847.

Subject: Re: [Elecraft] K3 - Steppir interfacing
I made up a Y cable to interconnect K3, SteppIR controller and
computer. Lots of Googling told me that the connections to SteppIR
controller should be only DTR and Gnd, so I made sure that was how it
was wired.
Your Google "sources" are nonsense. The direct version of this e-mail includes
the schematic for the *STEPPIR* Y cable.

So a couple of days ago I posted tale of woe, trying to get my newly
acquired K3 to work with MixW - well, thanks to a few off line e-mails
and some stumbling around, I got that working. Ditto, got N1MM+ working great.
Next - how to get the K3 to play with my SteppIR vertical antenna
controller. Worked fine with my ICOM 746PRO, where I had both MixW and
SteppIR autotracking working fine with the radio.
So: My computer is a Windows XP thing that I bought specifically
because it has an actual RS232 (9 pin) serial interface, so no need to
struggle with a serial to USB adapter. I made up a Y cable to
interconnect K3, SteppIR controller and computer. Lots of Googling
told me that the connections to SteppIR controller should be only DTR
and Gnd, so I made sure that was how it was wired. Other posts point
out that the CONFIG AutoInf should be set to Auto1 (one post said it
should be set to Norm, so I tried it both ways). I even tried setting
K3, SteppIR and computer to a slower data rate (9600) in case the 38k
rate was too fast. No joy. Did the obvious newbie stuff like turning
things on and off, plugging and unplugging cables - still NG.
As I said, my logging program and N1MM are working just fine (one at a
time, of course), and I could live without having the SteppIR do
autotracking as I change bands/frequencies, but dagnabbit!!! it's the
principle of the thing! I ought to be able to have everything working.
Any suggestions would be appreciated.
