That is a little like what I meant previously when I mentioned a "shim" -
not a technical term I know but something to transmit the signal.

Hi Stephen,

Glad we are all on the same page now.  I was talking to Bill, KD5TFD, at 
lunch time today and he suggested a simpler solution which would be to 
capture the data from the Janus board and place it into the input buffer of 
VAC.

I'll let Bill explain more of the details but it would be much faster, and 
simpler, than writing a driver.  Bill did mention that VAC can only run at a

max of 48ksps so that would have to be an acceptable limitation.
