Can you tell us how the FlexControl will connect.
Will it use a USB Port on the PC Running Smart SDR,
and/or will it connect to one of the USB Ports on the Back of the 6000 ???

Ethernet Cards work?
In the FLEX-6000, the DSP is done in the radio. If you pull up a
panadapter, place a slice receiver on the display and start listening to
the audio, the computer is not involved in anything except commanding the
radio and displaying the panadapter. You can turn off your computing and
audio will continue playing out the radio. A big DPC hit might make your
display stutter, but it will not affect your audio.

But shouldn't DPCs be much less an issue if at all with the 6000 series?
