[Elecraft] [K3]Computer interface & SteppIR

[Dick Dievendorff]

Whoops!  Got my ends backward.  Corrected note below:

We're puzzling over this.

I read the SteppIR "Y" document to have only RxD and ground connected at the
SteppIR side of the "Y".  If that's the case, it's hard to understand how
any data transmitted from the SteppIR would influence the K3.  

If the SteppIR controller were wiggling RxD, it might affect what the
computer sees. But not what the K3 sees.

Are you sure that the SteppIR Y cable has only RxD connected at the SteppIR
end?

I'm looking at http://www.steppir.com/files/Y%20-%20Cable.pdf as the diagram
for the SteppIR Y cable.
