We also have had (and still have) sporadic problems with connecting
FACSCalibur and PPC7600:

When you restart the PPC while the FACSCalibur is on and had been connected
to the PPC before, the same problem as in your case occurs.
We then switch off FACS and PPC, wait some minutes and then re-switch on
everything in the right order and most of the time it then will work.

This indeed is very annoying, an even more annoying problem is when
the connection obviously is lost *during* aquisition, what sometimes
happens, too. I hope BD is working on these problems.

Hope this helps a bit.
